I uploaded the CBLs via ZendTo last week. They are also attached. They include the temp logs, with the same presentation as we did for Rosetta 1: noting zero/reference elevation in log header; showing both coiled tubing depth and depth referenced to sea level on the up/down temp log overlay. READ Cased Hole is invoicing the temp logs separately, as for Rosetta 1. We did pump a minimal amount before logging in hole, and above 500’ while POH, and take fluid returns through the choke while RIH to keep the well liquid-packed and to maintain READ’s recommended 150 psi at the tool for CBL data quality. Due to unknown casing integrity, we couldn’t RIH with choke closed and let pipe displacement pressure up the casing.

Thanks, Adrienne Requested change to approved Sundry: Do not displace the well to 9.5 ppg brine after drilling out the surface plug with water. Continue using water as the work fluid until preparing to pump the surface cement plug, at which point the casing and annulus will be circulated to 9.8 ppg brine. Reason for change: To minimize brine mixing operations in the field. Also, since this is now a summer operation, freeze point is no longer a concern. We do plan to circulate the 10-3/4" x 5-1/2" annulus to 9.8 ppg brine via perforations at 290' before pumping the surface cement plug. Risk/mitigation: The risk is that the condition of the top ~40' of 5-1/2" casing, currently covered with a cement plug, is unknown. It is possible, but not likely, that section of casing does not have sufficient integrity to contain MPSP. The MPSP of 840 psi in the Sundry was calculated based on a gas gradient to surface from the deepest perforation at 1527' and a 12.5 ppg formation pressure. This is likely very conservative. The interval from 1270-1280' where a heavy flow of salt water with some gas was reported during drilling is cased and cemented. Per the well files, the only perforations are at 1518' - 1527'. A cased hole flow test of these perforations yielded no flow of water or gas. In the unlikely event the calculated MPSP occurs, the section of casing currently covered with the surface cement plug will see that pressure at the moment the plug is drilled out. At this point, the well will not yet have been circulated out, so KWF is not a mitigation. The approved Sundry states the surface plug will be drilled out with water. While drilling out the surface plug, we will be managing surface pressure via a choke, taking returns to an active circulating system comprised of a frac tank with diffuser, positive displacement pump, and filter skid, sending filtered fluid back to Fox's pump. The frac tank will be equipped with a gas monitor (we rented an extra gas monitor so one can be dedicated to the frac tank whenever we are taking returns). Please see attached diagram. ⚠️CAUTION: EXTERNAL SENDER This email originated from outside of the organization.

Please document in the email the reason for change and mention any risk/mitigation for making the change. The risk that comes to mind for me is that we might not know if the casing below the surface cement plug has integrity, so even though we have tested BOP/lubricator/stripper, are we sure the casing below the new wellhead has integrity to contain the surface pressure? In that case, using KWF as a barrier would be a mitigation. On the other side of that equation, we know that the well, with a gassy column of water is containing all but a trickle of fluid, and we will be prepared to divert that fluid and any reasonable increase in flow rate, so a consistent column of water should provide at least the same protection as we have today. Please also include in the email and procedure a piping diagram showing how the choke/diverter line, pumps and any return tanks will be plumbed?

Changes to the original version sent 2/13/25: 1. Since we’ll be conducting the work in the summer, I eliminated mention of heaters, heated water, and freeze protect. 2. I added cement details and an appendix with the lab test results. I’ve planned 2 separate slurries planned for Rosetta 4: a. Plug #1 inside 5-1/2” casing: i. Will be placed with CTU. ii. Includes retarder. Thickening time 3:57. b. Plug #2 inside 5-1/2” casing and 5-1/2” x 7-1/2” annulus: i. Will be circulated with cement unit rigged up directly to dry hole tree. ii. To ensure a good cement job with the known annular flow, this slurry includes the following: 1. Accelerant (CaCl2). Thickening time 2:01. 2. The FLAC is a polymer that also functions as a gas-blocking additive. Please let me know if you have questions or would like to meet to review.

Below I have listed 3 items we discussed during our 1/16/25 meeting. #1 and #2 are differences between the attached program and the approved Sundry. #3 is a follow-up to our discussion on big hole perf charges versus the Gator mechanical perforator for establishing circulation into the 5-1/2” x 10-3/4” annulus. 1. Planning not to displace the 5-1/2” casing to 9.5 ppg brine or water-based mud after drilling out the surface cement plug. Plan to stay with water. At the time of our meeting, I was inclined to use 9.6 ppg NaCl brine. However: Since we are using CTU, don’t need KWF. Regarding freeze point: we’ll be running a recirculation skid, so we’ll have an active circulation system much like a rig, with a heated diffuser tank to keep the water warm. We will follow Fox’s normal procedure for freeze protecting the CTU reel and the top ~100’ of the well when shutting down for the night, which is to blow down with nitrogen. If CTU is not able to complete the P&A and we need to prepare the well for a rig, we can circulate the well over to KWF before rigging down. We can mix brine or mud on location with Fox’s batch mixer. I do plan to displace the 5-1/2” x 10-3/4” annulus with 9.6 ppg NaCl brine prior to pumping cement plug #2. 2. Planning to use 15.3 instead of 15.8 ppg cement, as this is Fox’s normal practice for plugs pumped through coiled tubing. Plug #1: pumped through coiled tubing into 5-1/2” casing. Plan to use Fox’s “base” 15.3 ppg blend. Plug #2: circulated into 5-1/2” casing x 10-3/4” annulus after standing back coiled tubing. Plan to use a polymer FLAC (in addition to controlling fluid loss, this additive helps block gas inflow) and an accelerant (lessening transition time will also help block gas). I am still waiting on updated lab reports and will share as soon as they’re available. 3. Planning to use Gator Mechanical Perforator Tool for perforating 5-1/2” casing. This is not a change to the sundry, but we discussed it during our 1/16/25 meeting. At that time, I was leaning towards big hole perf charges. After a technical and cost analysis, I agree the Gator is superior to big hole perf charges and gives us flexibility to punch more holes on a single run if required. Please let me know if you have any questions. I’d be happy to set up a meeting to discuss the procedure.

and Remediation Program Rosetta 4 Plug and Abandon Detailed Procedure Houston, Alaska AOGCC 3 July 2025 18697-01 Rev. 2 1.0 Introduction The Rosetta 4 well is planned for plug and abandonment (P&A) as part of the AOGCC Orphan Well Plugging and Remediation Program. The P&A work will be conducted by ASRC Energy Services Alaska, Inc. (AES-AK) as operator, on behalf of the AOGCC. Rosetta 4 was spudded in August 1959 as an exploration test well. 10-3/4” surface casing was set at 301’ and cemented to surface. 8-3/4” hole was drilled to TD at 1627’. Well files include no mention of gas or oil shows other than gas mixed in with a “heavy flow of salt water at 1270’-1280’, approximately”, which required 12.5 ppg mud to shut off. After reaching TD, numerous flow tests were conducted on open hole intervals between 1535’ and TD, yielding varying levels of salt water and flammable gas flows. One open hole drill stem test (DST) from 1550’ – 1662’ yielded a rate of 8000 bpd of water. The well was suspended in October 1959. In 1961, Hackathorn Drilling planned to re-enter the well and drill to 5000’ but instead decided to run and cement 5-1/2” casing at 1627’ and perforate from 1518-1527’. The perforated interval was tested but showed no flow of gas or fluids. A 6-sack surface cement plug was placed in October 1961. Well files indicate that the USGS required the operator to re-enter the well again in 1962 to place a cement plug across the perforations from 1495-1545’, although this is not certain. Currently the well is leaking water/brine, with intermittent audible gas bubbling and LEL’s, from one of the open 2” wellhead side outlets. These side outlets provide a direct pathway from the 5-1/2” x 10-3/4” casing annulus to the environment. Observed leak data is ~2 cups per minute of water/brine, and up to 100% LEL when bubbling is active.

Plan forward will depend on log evaluation. Do not proceed with cementing without AOGCC approval. 4.5 Cement Plug #1 Per 20 AAC 25.112(a)(3) the objective of the cementing program is to provide cement coverage and isolation from 150’ below to 50’ above the base of freshwater at 490’. Thus, cement isolation is required from 440’ – 640’. This cementing program assumes the CBL will find cement coverage behind 5-1/2” casing adequate. If the CBL finds the TOC deeper than 440’, be prepared to adjust the current program to allow for deeper perforations. In this case, diagnostic and remedial work could include: x Remedial cement (perforate deeper and attempt cement squeeze) – requires a Sundry – Change Approved Program request. x Ultrasonic LDL to locate entry point of annular water and gas flow (Archer VIVID Seal memory tool; READ Cased Hole has one in Prudhoe Bay).

Additionally, the base of freshwater at 490’ must be cemented/isolated from 150’ below to 50’ above this point, as per 20 AAC 25.112.(a).(3). If these objectives are met, results of the CBL are not expected to lead to a significant change in the forward P&A plan, but to possibly refine overall plug placement and depth of perforations for cement placement within the 5-½” x 10-¾” annulus. The plan as written assumes TOC allows for the 5-½” x 10-¾” cementing operations to be conducted through perforations at ~290’, just inside the 10-¾” surface casing shoe. If the cement plug placement is adjusted from the plan in the approved Sundry, a Sundry – Change Approved Program request will be submitted. If it is determined that the remedial work required exceeds the capability of coiled tubing, the coiled tubing work will be concluded with this step and a plan developed to execute the remainder of the abandonment with another intervention tool will be developed and submitted. Meeting with Bryan McLellan (AOGCC Senior Petroleum Engineer), Danny Kara (AOGCC Independent Cost Estimator), Tim Brandenburg (AK-AES Project Manager), and Adrienne McVey (AK-AES Drilling Engineer) on 16 January 2025: Ideally: CBL shows good isolation of zones that yielded 8000 bpd water flows at 1270-1280' (required 12.5 ppg mud to kill) and 1550-1611', good isolation of base of freshwater at 490' (adequate cement required from 440' - 640'), and clean TOC that will allow perfing just inside the 10-3/4" shoe and circulating cement to surface in the 5-1/2" x 10-3/4" annulus. Cement is designed for fairly short thickening time, right-angle set, and has gas blocking additive (polymer); hopefully would be adequate to mitigate the small leak rate currently observed. But what if: 1. Cement above the water flow zones looks ratty: clearly the annulus is not currently in full communication with the water flow zones (leak rate from annulus side outlet is 2 cups/min = 0.125 gal/min = 4.3 bpd). If those water flow zones are the source of the leak to surface, something is currently choking off the flow/channel in the annulus. Would we worry that perforating deeper in the well might disturb the "choke" and open up the annulus more fully to the water flow zones, resulting in an increased leak rate to surface? Wouldn't be able to kill the annulus (surface shoe at 300' can't withstand KWF) and wouldn't be able to get a good cement job; wouldn't be able to stop flow to surface. Would we consider an ultrasonic LDL to find the leak path and inform our plan forward if the CBL looks poor above the water flow zones? 2. CBL shows some cement above the 10-3/4" shoe, making ability to circulate cement to surface in the annulus uncertain: would we consider making multiple cuts with Gator mechanical perforating tool and then using Hydrawell to try and clean up the annulus and provide a better circulation path? The result of the discussion was to leave the procedure open-ended and decide path forward pending CBL results. We will be using the Gator mechanical perforating tool, which gives the ability to make multiple sets of perforations in a single run. And we can source a memory ultrasonic LDL if desired (though this is not included in the cost estimate).

Thanks, Adrienne Requested change to approved Sundry: Do not displace the well to 9.5 ppg brine after drilling out the surface plug with water. Continue using water as the work fluid until preparing to pump the surface cement plug, at which point the casing and annulus will be circulated to 9.8 ppg brine. Reason for change: To minimize brine mixing operations in the field. Also, since this is now a summer operation, freeze point is no longer a concern. ⚠️CAUTION: EXTERNAL SENDER This email originated from outside of the organization. Do not click links or open attachments unless you recognize the sender and know the content is safe. We do plan to circulate the 10-3/4" x 5-1/2" annulus to 9.8 ppg brine via perforations at 290' before pumping the surface cement plug. Risk/mitigation: The risk is that the condition of the top ~40' of 5-1/2" casing, currently covered with a cement plug, is unknown. It is possible, but not likely, that section of casing does not have sufficient integrity to contain MPSP. The MPSP of 840 psi in the Sundry was calculated based on a gas gradient to surface from the deepest perforation at 1527' and a 12.5 ppg formation pressure. This is likely very conservative. The interval from 1270-1280' where a heavy flow of salt water with some gas was reported during drilling is cased and cemented. Per the well files, the only perforations are at 1518' - 1527'. A cased hole flow test of these perforations yielded no flow of water or gas. In the unlikely event the calculated MPSP occurs, the section of casing currently covered with the surface cement plug will see that pressure at the moment the plug is drilled out. At this point, the well will not yet have been circulated out, so KWF is not a mitigation. The approved Sundry states the surface plug will be drilled out with water. While drilling out the surface plug, we will be managing surface pressure via a choke, taking returns to an active circulating system comprised of a frac tank with diffuser, positive displacement pump, and filter skid, sending filtered fluid back to Fox's pump. The frac tank will be equipped with a gas monitor (we rented an extra gas monitor so one can be dedicated to the frac tank whenever we are taking returns). Please see attached diagram.

Please document in the email the reason for change and mention any risk/mitigation for making the change. The risk that comes to mind for me is that we might not know if the casing below the surface cement plug has integrity, so even though we have tested BOP/lubricator/stripper, are we sure the casing below the new wellhead has integrity to contain the surface pressure? In that case, using KWF as a barrier would be a mitigation. On the other side of that equation, we know that the well, with a gassy column of water is containing all but a trickle of fluid, and we will be prepared to divert that fluid and any reasonable increase in flow rate, so a consistent column of water should provide at least the same protection as we have today. Please also include in the email and procedure a piping diagram showing how the choke/diverter line, pumps and any return tanks will be plumbed?

Changes to the original version sent 2/13/25: 1. Since we’ll be conducting the work in the summer, I eliminated mention of heaters, heated water, and freeze protect. 2. I added cement details and an appendix with the lab test results. I’ve planned 2 separate slurries planned for Rosetta 4: a. Plug #1 inside 5-1/2” casing: i. Will be placed with CTU. ii. Includes retarder. Thickening time 3:57. b. Plug #2 inside 5-1/2” casing and 5-1/2” x 7-1/2” annulus: i. Will be circulated with cement unit rigged up directly to dry hole tree. ii. To ensure a good cement job with the known annular flow, this slurry includes the following: 1. Accelerant (CaCl2). Thickening time 2:01. 2. The FLAC is a polymer that also functions as a gas-blocking additive. Please let me know if you have questions or would like to meet to review.

Below I have listed 3 items we discussed during our 1/16/25 meeting. #1 and #2 are differences between the attached program and the approved Sundry. #3 is a follow-up to our discussion on big hole perf charges versus the Gator mechanical perforator for establishing circulation into the 5-1/2” x 10-3/4” annulus. 1. Planning not to displace the 5-1/2” casing to 9.5 ppg brine or water-based mud after drilling out the surface cement plug. Plan to stay with water. At the time of our meeting, I was inclined to use 9.6 ppg NaCl brine. However: Since we are using CTU, don’t need KWF. Regarding freeze point: we’ll be running a recirculation skid, so we’ll have an active circulation system much like a rig, with a heated diffuser tank to keep the water warm. We will follow Fox’s normal procedure for freeze protecting the CTU reel and the top ~100’ of the well when shutting down for the night, which is to blow down with nitrogen. If CTU is not able to complete the P&A and we need to prepare the well for a rig, we can circulate the well over to KWF before rigging down. We can mix brine or mud on location with Fox’s batch mixer. I do plan to displace the 5-1/2” x 10-3/4” annulus with 9.6 ppg NaCl brine prior to pumping cement plug #2. 2. Planning to use 15.3 instead of 15.8 ppg cement, as this is Fox’s normal practice for plugs pumped through coiled tubing. Plug #1: pumped through coiled tubing into 5-1/2” casing. Plan to use Fox’s “base” 15.3 ppg blend. Plug #2: circulated into 5-1/2” casing x 10-3/4” annulus after standing back coiled tubing. Plan to use a polymer FLAC (in addition to controlling fluid loss, this additive helps block gas inflow) and an accelerant (lessening transition time will also help block gas). I am still waiting on updated lab reports and will share as soon as they’re available. 3. Planning to use Gator Mechanical Perforator Tool for perforating 5-1/2” casing. This is not a change to the sundry, but we discussed it during our 1/16/25 meeting. At that time, I was leaning towards big hole perf charges. After a technical and cost analysis, I agree the Gator is superior to big hole perf charges and gives us flexibility to punch more holes on a single run if required. Please let me know if you have any questions. I’d be happy to set up a meeting to discuss the procedure.

The original plan for re-heading the well involved cutting off the existing wellhead and casing strings at surface and installing a conventional well head. Under the modified plan, the wellhead will be installed directly onto the 5-1/2” long string. This method is less invasive and reduces the need to cut the casing strings with the well leaking water and gas from the surface x long string annulus.

Sincerely, Doug Cismoski VP of Drilling, Projects and Engineering ASRC Consulting & Environmental Services, LLC OUR PURPOSE: TO FIND SUSTAINABLE SOLUTIONS FOR A SUSTAINABLE FUTURE ASRC Energy Services, LLC | 3900 C Street, Suite 701, Anchorage, Alaska 99503 | 907.339.6200 | asrcenergy.com Page 2 of 9 1.0 Well Summary – Rosetta 4 The Rosetta 4 well is planned for plug and abandonment (P&A) as part of the State of Alaska AOGCC Orphan Well Program. The P&A work will be conducted by AES-AK as Operator, on behalf of the State of Alaska AOGCC. Operations on Rosetta 4 are scheduled to begin 3Q of 2024. General Well Information Status: Orphan Well – See attached ‘Current Wellbore Schematic’ (Figure 1.1-1) for details. An active water / brine leak of ~2 cups/minute with intermittent audible gas bubbling was observed during a June 2023 site visit. The liquid and gas were coming from the side-outlet of the wellhead for the 5-½” x 10-¾” casing annulus. Gas measurements varied from 10% to 60% LEL at the wellhead side outlets. Base of Fresh Water: Estimated at 490’ MD / 490’ TVD Reservoir Pressure: Based upon information within the AOGCC & DNR Rosetta 4 well files, there is no mention of gas and oil shows seen during the original drilling, other than gas noted to be mixed in with a “heavy flow of salt water at 1270-1280’, approximately”. This flow was eventually shut off with a 12.5 ppg mud while drilling towards TD. After reaching TD at 1627’ numerous flow tests were performed across an open hole interval from 1535’ to 1624’ with some delivering varying levels of salt water and flammable gas flows, and other tests resulted in no flow at all. After running and cementing of the 5-½” casing an additional cased hole flow test was performed on the perforated interval from 1518’ to 1527’, which resulted in no flow of either gas or water. During the proposed P&A operations, this perforated section should be the only formation in communication, as shown in Figure 1.1-1. Abnormal Pressure: As noted above, the interval from 1270-1280’ delivered a strong flow of salt water and was held back with 12.5 ppg mud while drilling towards TD. Records also show the 5-½” casing was run and cemented with 12.5 ppg mud. Therefore, an expected worst case for the well is 12.5 ppg EMW for this interval and on to TD. MASP: The Maximum Anticipated Surface Pressure is based upon a gas gradient to surface from the deepest perforation at 1527’ MD/TVD and a 12.5 ppg formation pressure. MASP is calculated as ~840 psi. Rig for P&A Ops: Fox Energy Services Coiled Tubing Unit (CTU) Wellhead: Vault 10-¾” Casing x 11” 5M, 11” 5M x 7-1/16” 5M (see Figure 1.1-3 for details) BOP Configuration: 4-1/16” 10M BOPE (see Figure 1.1-4 for details). BOP Test Pressure: 1000 psi (g ) An active water / brine leak of ~2 cups/minute with intermittent audiblep gas bubbling was observed during a June 2023 site visit.

This moves the plug out of open hole, which should improve chances of establishing circulation in the 5-½” x 10-¾” annulus and aid cement plug placement, as proposed. The 5-½” will be filled with cement across this interval to meet regulation requirements. 1.1 P&A Procedure – Rosetta 4 Pre-Coiled Tubing Work 1. Prepare location for coiled tubing operations and remove any debris / solid waste specified for clean- up. 2. Excavate around well to provide access to the exiting casing and for installation of sealed well cellar. 3. Perform hot tap on 10-¾” and 5-½” casings at desired cut-off depth (for wellhead installation) to ensure no trapped pressure exists on the well. 4. Cut 10-¾” and 5-½” to remove the old wellhead and place both casing stubs at the desired elevation for installation of new wellhead equipment. Verify the presence of cement in the 5-½” casing and look for signs of cement in the 5-½” x 10-¾” annulus at surface. Note: Cement was confirmed during the June 2023 site visit in the 5-½” casing, however not in the 5-½” x 10- ¾” annulus, which had water and gas shows flowing from the side outlet. Based upon the observed water flow and information from the 5-½” cement records, it is not expected to find quality cement in the annulus at surface. 5. Install sealed well cellar and attach new starting head / wellhead configuration. Coiled Tubing/E-Line Based Operations 1. Move in and rig up Coiled Tubing Unit and equipment. Note: Notify AOGCC 24 hours prior to the BOP test. 2. Nipple up 4-1/16”, 10M BOPE and test 250 psi low / 1000 psi high. 3. Make up cleanout assembly and drill out surface cement plug in 5-½” casing. x Records indicate a 6 sack cement plug set at surface, equating to 40’ in the 5-½” casing. x The surface plug will be drilled with water and then the well displaced to a 9.5 ppg brine or water-based mud for P&A operations. The perforated interval in the well demonstrated no flow potential during a 48 hour cased hole flow test as part of the original well operations, and therefore the 9.5 ppg weight should be more than adequate to manage the exposed formation pressure. 4. Once the surface cement plug is drilled out, run in hole to PBTD at ~1589’ (depth based upon 9/8/1962 cased hole neutron log information). Wash down and tag PBTD, setting weight to confirm firm bottom. Note: As part of the final P&A in September 1962, the possibility exists that a cement P&A plug was placed within the 5-½” casing to isolate the perforations from 1518’ – 1527’. There is no record of this plug in the well Variance is not required. 20 AAC 25.112(b) refers to open hole below the deepest casing string. This well had casing run to TD, so for purposes of this regulation, there is no open hole in the well. Fluid density during cased hole flow test is unknown. -bjm Perform quantitative methane-monitoring per DOI procedure to compare with post-P&A monitoring. Pressure test wellhead seals to 900 psi. -bjm OUR PURPOSE: TO FIND SUSTAINABLE SOLUTIONS FOR A SUSTAINABLE FUTURE ASRC Energy Services, LLC | 3900 C Street, Suite 701, Anchorage, Alaska 99503 | 907.339.6200 | asrcenergy.com Page 4 of 9 file, however the plug was a requirement of the US DOI, who later approved the final P&A in November 1962. The intent is to verify this plug is in place while running in the hole, and if encountered, only clean-out enough of the plug to verify good cement and a firm base for the upcoming cement plugs, without exposing the perforations below. Notify AOGCC 24 hours prior to tag of cement plug to allow witnessing of the operations. 5. Pull out of the hole, lay down BHA. 6. If available and if deemed of greater efficiency than running on e-line, run the CBL in memory mode on Coiled Tubing from PBTD to surface in the 5-1/2” casing. Otherwise, proceed to step 7. 7. Rig down the Coiled Tubing Unit and equipment. 8. Rig up e-line and run CBL from PBTD to surface in 5-½” casing. Submit results of CBL to AOGCC immediately and review log to determine TOC, using this information to refine the plan forward for the P&A plug placement, if necessary. Approval of plan forward must be obtained from the AOGCC prior to proceeding with any cement operations. Note: The CBL will be reviewed to ensure annular cement provides the appropriate isolation of the interval from ~1200’–1270’ where gas was noted to be mixed in with a heavy flow of saltwater. Additionally, the base of freshwater at 490’ must be cemented/isolated from 150’ below to 50’ above this point, as per 20 AAC 25.112.(a).(3). If these objectives are met, results of the CBL are not expected to lead to a significant change in the forward P&A plan, but to possibly refine overall plug placement and depth of perforations for cement placement within the 5-½” x 10-¾” annulus. The plan as written assumes TOC allows for the 5-½” x 10-¾” cementing operations to be conducted through perforations at ~290’, just inside the 10-¾” surface casing shoe. If the cement plug placement is adjusted from the plan in the approved Sundry, a Sundry - Change Approved Program request will be submitted. If it is determined that the remedial work required exceeds the capability of coiled tubing, the coiled tubing work will be concluded with this step and a plan developed to execute the remainder of the abandonment with another intervention tool will be developed and submitted. 9. Rig up Coiled Tubing Unit and equipment. 10. Nipple up 4-1/16” 10M BOPE and test 250 psi low / 1000 psi high. 11. Make-up cementing stinger, run in hole to PBTD depth as established from prior clean-out run. Note: Notify AOGCC 24 hours prior to pumping of initial and all cement plugs to allow witnessing of the operations. 12. Rig up cement unit. Mix and pump 15.8 ppg cement, laying in the plug from PBTD up to 290’ (assuming deepest potential PBTD of ~1589’, a 33 bbl plug volume will result in a TOC ~50’ above the planned plug height of 290’). Circulate the top of the plug off at 290’.

BOP Configuration 1 McLellan, Bryan J (OGC) From:Brandenburg, Timothy <tbrandenburg@asrcenergy.com> Sent:Friday, August 2, 2024 2:44 PM To:McLellan, Bryan J (OGC) Cc:Danny Kara Subject:RE: Rosetta 4 (PTD 159-008) question Bryan, The basis for the 9.5 as a Ʊnal Ʋuid is that the perforations are likely isolated and that the tested interval failed to Ʋow on extended test, though in fact the Ʋuid type or density in place at the time of test is not known. The well history strongly suggests that a plug was placed from1545’ to 1495’ to isolate the only recorded perforations in the 5-1/2” at 1518-1527’. The question remains as to the quality and location of that plug. The deepest depth recorded after running and cementing 5-1/2” is a Neutron Log to 1,589’ (38’ from the shoe). If this is the case, there is enough rat hole that if the plug moved down it could have uncovered the perfs. If the plug is in place and eƯective, the 9.5 ppg will be suƯicient baring a casing leak from a zone of higher pressure above the plug. The only perforations (1518-1527’) were reported to have been “left open for 48 hours without a resultant Ʋow of gas or Ʋuid”. Either the perforated interval has very low perm, the perforations were not successful or there was kill weight Ʋuid in the hole when testing. The 9.5 assumes that they did not perforate with 12.5 mud in the hole and likely had at most a brine in the well. Also, based on the overall Rosetta history and practice, it is also likely that they swabbed for this test though there is no record of it. The completion Ʋuid assumption may be incorrect but, in any case, actual kill weight Ʋuid will be determined once the well has been displaced to a known gradient Ʋuid. The MASP is conservatively estimated using the 12.5 ppg mud weight used to drill the well which equals an MASP of ~840 psi with a gas gradient as stated in the Sundry Application. When we drill the plug out with coil, the worst case scenario will be if gas has fully displaced the Ʋuid column to 1527’ (basis for the MASP) or to a shallower casing leak. Once through the plug, we will learn what Ʋuid is initially present (gas or Ʋuid packed) and at what surface pressure once stabilized. Once we get to PBTD and get the well turned over to a known gradient Ʋuid we will verify the well is dead, and if not kill accordingly. Following is a high level history of the well from the time the 5-1/2” casing was run: June 19, 1961 – Ran 5-1/2” casing to 1,627’ (no record of Ʋuid used to displace cement) September 8, 1961 – “Perforated 1518’ to 1527’ No resultant Ʋow of gas or Ʋuid” “Wellhead Ʋowline left open for 48 hours without a resultant Ʋow of gas or Ʋuid” October, 1961 - well abandoned with 6’ plug at surface (Note: The operator failed at that time to place a plug from1545’ to 1495’ as had been requested in an approval letter from the regional Oil and Gas Supervisor of the USGS) February 6, 1962 – the operator commits to the USGS that they will re-enter the well during their summer program and will “place the required plug in the approved manner” CAUTION: This email originated from outside the State of Alaska mail system.

In the Reservoir Pressure summary in section 1.0, you state that the Ʋow was controlled with 12.5 ppg mud. Do you know the Ʋuid density in the hole during the time when the Ʋow test was performed?

Please contact me at 907-339-7410 or William Isaacson at 907-339-6455 with any questions. Sincerely, Doug Cismoski Director of Drilling and Field Management ASRC Consulting & Environmental Services, LLC Rosetta 4 (PTD 159-008) Southcentral, Alaska Rev. 0 November 2023 1.0 Well Summary – Rosetta 4 The Rosetta 4 well is planned for plug and abandonment (P&A) as part of the State of Alaska AOGCC Orphan Well Program. The P&A work will be conducted by AES-AK as Operator, on behalf of the State of Alaska AOGCC. Operations on Rosetta 4 are scheduled to begin 1Q of 2024. General Well Information Status: Orphan Well – See attached ‘Current Wellbore Schematic’ (Figure 1.1-1) for details. An active water / brine leak of ~2 cups/minute with intermittent audible gas bubbling was observed during a June 2023 site visit. The liquid and gas were coming from the side-outlet of the wellhead for the 5-½” x 10-¾” casing annulus. Gas measurements varied from 10% to 60% LEL at the wellhead side outlets. Base of Fresh Water: Estimated at 490’ MD / 490’ TVD Reservoir Pressure: Based upon information within the AOGCC & DNR Rosetta 4 well files, there is no mention of gas and oil shows seen during the original drilling, other than gas noted to be mixed in with a “heavy flow of salt water at 1270-1280’, approximately”. This flow was eventually shut off with a 12.5 ppg mud while drilling towards TD. After reaching TD at 1627’ numerous flow tests were performed across an open hole interval from 1535’ to 1624’ with some delivering varying levels of salt water and flammable gas flows, and other tests resulted in no flow at all. After running and cementing of the 5-½” casing an additional cased hole flow test was performed on the perforated interval from 1518’ to 1527’, which resulted in no flow of either gas or water. During the proposed P&A operations, this perforated section should be the only formation in communication, as shown in Figure 1.1-1. Abnormal Pressure: As noted above, the interval from 1270-1280’ delivered a strong flow of salt water and was held back with 12.5 ppg mud while drilling towards TD. Records also show the 5-½” casing was run and cemented with 12.5 ppg mud. Therefore, an expected worst case for the well is 12.5 ppg EMW for this interval and on to TD. MASP: The Maximum Anticipated Surface Pressure is based upon a gas gradient to surface from the deepest perforation at 1527’ MD/TVD and a 12.5 ppg formation pressure. MASP is calculated as ~840 psi. Rig for P&A Ops: Team Snubbing International 340k Hydraulic Workover (HWO) Unit 101 Wellhead: 10-¾” Casing x 11” 5M (see Figure 1.1-3 for details) BOP Configuration: 13-5/8” 5M BOPE - Annular/Pipe Rams/Blind/Choke & Kill Line (see Figure 1.1- 4 for details). 5 Station Accumulator. BOP Test Pressure: 1000 psi Choke Manifold: 4-1/16” 5M (see Figure 1.1-4 for configuration details) (g ) active water / brine leak of ~2 cups/minute with intermittent audiblep gas bubbling was observed during a June 2023 Rosetta 4 (PTD 159-008) Southcentral, Alaska Rev. 0 November 2023 Regulatory Variance / Waiver Requests Contingent upon the results of cement evaluation logging showing adequate isolation of the base of fresh water at 490’, a variance to the requirements of 20 AAC 25.112 (b) is being requested to allow moving the cement plug segregating cased and uncased sections of the 5-½” x 10-¾” annulus up into the surface casing shoe, rather than across the casing shoe. This moves the plug out of open hole, which should improve chances of establishing circulation in the 5-½” x 10-¾” annulus and aid cement plug placement, as proposed. The 5-½” will be filled with cement across this interval to meet regulation requirements. 1.1 P&A Procedure – Rosetta 4 Pre-Rig Work 1. Prepare location for rig operations and remove any debris / solid waste specified for clean-up. 2. Excavate around well to provide access to the exiting casing and for installation of sealed well cellar. 3. Perform hot tap on 10-¾” and 5-½” casings at desired cut-off depth (for wellhead installation) to ensure no trapped pressure exists on the well. 4. Cut 10-¾” and 5-½” to remove old wellhead and place both casing stubs at the desired elevation for installation of new wellhead equipment. Verify the presence of cement in the 5-½” casing and look for signs of cement in the 5-½” x 10-¾” annulus at surface. Note: Cement was confirmed during the June 2023 site visit in the 5-½” casing, however not in the 5-½” x 10- ¾” annulus, which had water and gas shows flowing from the side outlet. Based upon the observed water flow and information from the 5-½” cement records, it is not expected to find quality cement in the annulus at surface. 5. Install sealed well cellar and attach new starting head / wellhead configuration. Rig Based Operations 1. Move in and rig up P&A rig and equipment. Note: Notify AOGCC 24 hours prior to commencing P&A operations and for the upcoming BOP test. 2. Nipple up BOPE and test to 250 psi low / 1000 psi high (annular to 1000 psi). 3. Make up 4-¾” cleanout assembly and drill out surface cement plug in 5-½” casing using snubbing force as required to aid in drilling the plug. x Records indicate a 6 sack cement plug set at surface, equating to 40’ in the 5-½” casing. x To manage the risk of trapped pressure beneath the shallow cement, plans are to divert flow from below a closed stripping annular (above the BOP stack) and through the rigs mud gas separator while drilling the surface plug. x The surface plug will be drilled with water and then the well displaced to a 9.5 ppg brine or water-based mud for P&A operations. The perforated interval in the well demonstrated no flow potential during a cased hole flow test as part of the original well operations, and therefore the 9.5 ppg weight should be more than adequate to manage the exposed formation pressure. Perform pre-P&A methane measurement per DOI recommended procedure. -bjm Rosetta 4 (PTD 159-008) Southcentral, Alaska Rev. 0 November 2023 4. Once the surface cement plug is drilled out, add 5-½” casing scraper to the 4-¾” cleanout BHA and run in hole to PBTD at ~1589’ (depth based upon 9/8/1962 cased hole neutron log information). Wash down and tag PBTD, setting weight to confirm firm bottom. Note: As part of the final P&A in September 1962, the possibility exists that a cement P&A plug was placed within the 5-½” casing to isolate the perforations from 1518’ – 1527’. There is no record of this plug in the well file, however the plug was a requirement of the US DOI, who later approved the final P&A in November 1962. Plans are to look for this plug as running in to PBTD, and if encountered, only clean-out enough of the plug to verify good cement and a firm base for the upcoming cement plugs, without exposing the perforations below. Notify AOGCC 24 hours prior to tag of cement plug to allow witnessing of the operations. 5. Pull out of the hole, lay down bit and BHA. 6. Rig up E-line unit and run CBL from PBTD to surface in 5-½” casing. Submit results of CBL to AOGCC immediately and review log to determine TOC, using this information to refine the plan forward for the P&A plug placement, if necessary. Approval of plan forward must be obtained from the AOGCC prior to proceeding with any cement operations. Note: The CBL will be reviewed to ensure annular cement provides the appropriate isolation of the interval from ~1200’–1270’ where gas was noted to be mixed in with a heavy flow of saltwater. Additionally, the base of freshwater at 490’ must be cemented/isolated from 150’ below to 50’ above this point, as per 20 AAC 25.112.(a).(3). If these objectives are met, results of the CBL are not expected to lead to a significant change in the forward P&A plan, but to possibly refine overall plug placement and depth of perforations for cement placement within the 5-½” x 10-¾” annulus. The plan as written assumes TOC allows for the 5-½” x 10-¾” cementing operations to be conducted through perforations at ~290’, just inside the 10-¾” surface casing shoe. If the cement plug placement is adjusted from the plan in the approved Sundry, a Sundry - Change Approved Program request will be submitted. 7. Make-up cementing stinger, run in hole to PBTD depth as established from prior clean-out run. Note: Notify AOGCC 24 hours prior to pumping of initial and all cement plugs to allow witnessing of the operations. 8. Rig up cement unit. Mix and pump 15.8 ppg cement, spotting as a balanced plug from PBTD up to 950’ (assuming deepest potential PBTD of ~1589’, results in a 16 bbl plug volume). Pull up to top of plug at 950’ and circulate the well clean above plug. 9. WOC until desired compressive strength is reached. Run in hole and tag top of plug to confirm location. Note: As per guidance from the AOGCC, weight testing of this bottom plug to requirements of 220 AAC 25.112 (g) will serve as a test of the base for following plugs, eliminating need for weight test verification of those plugs. 10. With bottom of the cement stinger at 950’, mix and pump 17 bbls of 15.8 ppg cement, spotting as a balanced plug from 950’ to 250’. Pull up to 290’ (~40’ below top of plug) and circulate the well clean, leaving a clean top of cement at 290’. Pull out of hole and lay down cement stinger. 11. Rig up e-line and perforate the 5-½” casing over a 5’ interval immediately on top of cement plug at 285’-290’. 12. Close the blind rams and attempt to establish circulation around the 5-½” casing through the perforations. If successful, displace the 5-½” x 10-¾” annulus to 9.5 ppg brine/mud while working up to desired cementing rate. Shut down and monitor to verify the well is dead.

Rig up cement unit. Pump ~28+ bbls of cement (final weight to be determined) down 5-½” casing, through perforations at 290’ and out 5-½” x 10-¾” annulus valves. Continue to pump until good cement returns to surface and both casing and annulus are filled to surface. Flush lines and equipment of cement as required, leaving cement at approximately ground level. Note: Final details of cement weight and cementing surface configuration will be worked with suppliers in detailed planning stage. 15. Nipple down BOPE. Rig down and move out P&A rig and associated equipment. Post-Rig Work 1. Remove wellhead and well cellar. Complete excavation as needed around the well to allow cutting the 10-¾” and 5-½” casing strings to a minimum depth of 3 ft below ground level for final P&A.

Soyster, Re: Rosetta Wells 3 and 4A Oil and Gas supervisor U. S. Geological Survey Box 259, Anchorage. Dear Mr Soyster: Enclosed please find three copies of subsequent report of abandonment on our Rosetta No 3 well, covering the final plugging and erection of the steel marker and identification on Rosetta No 3 well. We wish to ask your indulgence for a time, as to actually moving the derricks off of the well locations, for the following reasons - 1. While we recognize that the y will have to be moved, it will cause us considerable unnecessary expense to have to move them twice at this time. We expect to move the Emsco from 4A to a new. drilling location sometime this winter or early spring. We have already removed the rotary table, all drilling pipe , tubing, cable, drilling collars, etc. , from the No 3 location, but do not have a suitable crew available currently to dismantle the derrick itself. 2. Since the oil and gas lease itself has now expired, but is under State selection, there will be a delay of several months before the acreage can be processed for further filing, even if in the face of abandonment of both wells, someone should be interested in a new filing. 3. We have written permission from the entryman who filed for homeistead rights covering both well sites, to leave the equipment standing for the time being. We sincerely believe that there is no practical reason that leav- ing the derricks in place for a time would cause any complications, and it would save a considerable amount of otherwise duplicated expense to ourselves. If possible, we would much prefer to spend the money saved toward further exploration for oil and gas in the general area where we still have current leases. I Ci `; la 3) OCT g AD Thanking you for your consideration of the situation, we are Very truly yours SAI CHORAGE !S JD"/0IL'DEV. Ii` eG org H.

Wunnicke sugjEGT:Field Inspection of abandonment and location clean up of Anchorage Gas and Oil Development Company's Rosetta No's. 3, 4, and 4A. Lease No. A-019332. The subject well locations were inspected October 3, 1463 by Messrs. Soyster and Wunnicke. A satisfactory monument had been installed on Rosetta #3. The 1204- Standard derrick with some of the drilling equipment was still in place over the hole. The mud pump had`been disconnected and moved a few feet off location. The reserve pit had not been covered and there is considerable debris scattered around the location. A satisfactory monument has been installed on We11'#4, and the cellar had been filled. Rosetta #4A is located about 75 feet from Rosetta #4. A satisfactory monument had been installed on Rosetta #4A. The jack knife derrick, engines, draw works, mud pump and engine were still in place over the abandoned hole. A considerable amount of leveling and clean up remains to be done. Mr. and Mrs. (Ruby) Manion, caretakers near the Rosetta #1 well informed us that Mr: Geo. Tucker has recently been in the process of cleaning up the subject locations. As a matter of information - A standard drilling derrick is in place over the abandoned well, Rosetta #1 located on a fee land lease. At this well most of the draw works and other machinery has been removed and there were 15 joints of 7" 23# N-80 casing at No. 1 location. W. C.

GOVUNMENT PRINTING MICK MEMORANDUM TO: THRU: State of Alaska Alaska Oil and Gas Conservation Commission 'David John~ Chairm~"'~'- Blair Wondzell, P. I. Supervisor 9/~.~ FROM: John Spauldina.~fl~ SUBJECT: Petroleum insp..(~.l,lA~ DATE: October 23,1994 FILE NO: ROSETTA.doc Inspection of Rosetta Wells Vicinity of Houston Ak... ', Friday October, 23,1.994: I traveled by POV from my residence to the area near Houston Ak. to inspect the 5 Rosetta well locations for leaks of oil, gas water. Due to the new growth of brush and quite tall grass I was able to Iocate'~ of the 5 wells, ( wells 2,3,4,&4A. Rosetta #2: The 10 112" casing extends about 12' above ground level and has a flange welded to the top with a steel plate bolted to the top. There are two side outlets, one near the flange ( 2" ) and one aboUt 4' from the flange ( I 1/2" ). The 2" side outlet appears to be plugged. The I 112" outlet is open and does not appear to have any hydrocarbons or water escaping from it. Water is bubbling up around the casing and is flowing down the highway cut toward the highway; due to the sandy nature of the soil, the water is flowing a distance of 10 to 15 feet before disappearing. I dropped a rock into the 1 1/2" side outlet and was able to detect fluid at or very near the surface, The water coming from around the casing does not appear to have any hydrocarbons in it, although a slight smell of gas can be detected. I recommend that the State of AK. consider a proper, abandonment of Rosetta well #2 in the near future. ~osetta.#3: There is a 6 1/2" marker post welded to the casing head extending 5 1/2" above ground level. The marker is properly marked with the well name, section, township, range and meridian. The well marker is located in the middle of the MEA power line ri.qht of way constitutin~ a personal hazard as these ROW's are quite often used by ATV's durin.q the summer months & snowmachines in the winter months. There is a rusted area where the marker post is welded to the casing head; it does not show any leakage of any type. The location is cluttered with old rig junk and an abandoned camper. The location is growing over with alders and small birch covering up much of the existing rig junk. Rosetta #4: A properly marked 4" capped steel pipe is welded to the 6" casing head. As noted in a previous report dated 10125/71tthe 1 112" valve located on the 6" casing was found to be operative. I found this valve to be in the open position and was unable to close it. There did not appear to be any hydrocarbons escaping from this valve or the several bullet holes in the 4" marker post. The area in and around the cellar box has some water seepage that appears to be somewhat salty. .Rosetta.#4A: Located approximately 75' from Rosetta #4, has a properly marked 4" capped steel pipe, with well name, section, township, range and meridian. No leaks were found in the area immediately adjacent to the casing head. the marker post has bullet holes in it with no apparent leakage. As noted in the 10/15/71. r. eport at that time, parts of a rig were scattered around both Rosetta 4 and 4A, all junk has been removed and everything looks to be in excellent shape. Rosetta #1: I was unable to locate this well or the diamond core hole located next to Rosetta #1. The area has grown over with quite dense vegetation and the well has no known marker post. This well is of some concern, as the 10/15/71 report indicates there was some leakage arond the casing of the well and also from the 3" diamond core hole. I will return in the spring prior to the grass getting as tall and try locate and inspect the wells in question. Summary and Recommendations: I inspected Rosetta wells 2,3,4&4A and found all to be in fair condition with the exception of Rosetta 2 as noted above.' I recommend that Rosetta 2 be considered for surface abandonment, # 3 be cut off below ground level and minor work that should be done to the other two Wells. Property ownership will need to be determined. FORM NO 9 1964— A SITE NO. y I,?`vl` ;' I I I U S. DEPT.

Gilbreth, Jr. ~ j / Chief Petroleum Engineer FROM: Karl L. VonderAhe State of Alaska DEPARTMENT OF NATURAL RESOURCES DIVISION OF OIL ~ GAS DATE : October 15, 1971 /.,~,/J .~~ Inspection of Rose~a Wells ,~x .,~/'v SUBJECT: Petroleum Engineer ?"' L-- '~ & Vicinity Near Houston. Left the office October 14 at 9:20 A. M. and drove, with Don Blasko, U.S.B.M. Engineer, in a Federal car, to Houston, arriving there at 10:45 A. M. We visited the location of all five Rosetta wells and checked them for leaks of gas, oil and water. ~Rosetta f/1 has no marker. The casinghead is in the remains of a cellar with board sides. The top of the casing is about two feet below ground level and about one foot above the bottom of the cellar. It is 8-5/8" (est.) casing with a steel plate welded on top. There are no side connections aboveground, but there is a leak in the casing a few inches below the surface from which a very small amount of gas is bubbling. We took a liter sample of the gas by water displacement. There also appears to be a very slight seepage of water which is very salty. Also caught a sample of this water. Either the water seepage is very, very slight or it is seeping away into the surrounding formation, as so little is present it was difficult to get even a liter sample. Alongside, to the south toward the railroad, is a sump of about 15' X 60' which is standing nearly full of water. About 90 feet SE of Rosetta ~;1 a 3" pipe protrudes 7" aboveground and from this is flowing a stream of water with considerable gas bubbling up through it. The water flow was measured and found to be one gallon a minute, or 34 barrels per day. The water is slightly brackish. 'A liter sample of the gas was caught by water displacement and a gallon sample of the water was taken. Don Blasko is sending the gas for analysis and the water for salinity determination. At present we have no way of identifying this well, but it is known that Tucker and Peterson requested the Bureau of Mines to leave their diamond core hole ?~2 unplugged for their use. Because of the size of the pipe from which the water is flowing it would indicate a diamond core hole rather than a rotary-drilled hole for oil exploration. Tucker & Peterson may have wanted it left open for a water supply for their drilling rigs. While brackish, the water could be used for drilling mud and cooling water for engines. This possibility should be explored to identify the well and the responsible party. Considering it is only a 3" pipe and is flowing water, the latter seems more likely. There'is no shOwing'of oil in'this water or adjoining the surface stream from it. There is a great deal of iron oxide below as the stream flows through a lot of discarded thread protectors, collars and barrels. The stream flows for about 60 feet ~_~ from the highway and toward the railroad; here it seeps into the ground so that beyond this point down to the base of the railroad fill. there is no water visible on the surface. The water is not salty enough to show any effect upon the vegetation. · O. K. Gilbreth, Jr. -2- Octobe~ :15.', 19 71 About 36 feet SE and 54 feet NE from this '%~ater well" is a 10-1/2" casing protruding 3-1/2 feet above-a-concrete .block. It.has a-flange welded-on top and a steel plate bolted to the flange. There is a 1-1/2" pipe stub welded into the casing near its base. This pipe stub is open and a pebble thrown into it can be heard rattling down the casing showing that there is no fluid near the surface. The protruding casing is serving as a marker, as the well name "Rosetta #2" and the 1/4 - 1/4 section, township and range are bead welded on it. At this time there is no water seepage showing on the highway cut face or in the ditch; all water showing on the surface is flowing away from the highway and toward the railroad. As the highway cut is through a mixture of sand and gravel it is possible that with winter temperatures the water from the "water well" may freeze on the surface to the point where the water may be diverted in the other direction and seep through the gravels to the highway. It is also possible that a subsurface leak in either Rosetta #1 or #2 from which water may now be seeping toward the railroad could be the cause of water going the other way through the gravels when it gets cold enough to freeze and seal the seepage, which may now be moving southwestward, and reverse the direction of flow. However., we were unable to find evidence of any fluid reaching the surface away from either of these wells. Any oil found in the vicinity of the railroad must have come from spills originated by the railroad. Blasko dug a small depression next to the wellhead"~' in the cellar of Rosette #1 and while waiting for the water to clear to get a sample of it we drove into Willow for lunch and to get' some matches to test~ the. gas for flammability. Upon returning we. checked .the gas coming from the "water well" and found it would sustain a flame for a few seconds -- probably methane. We then drove to Rosetta #3 which has. a 6-1/2" pipe marker welded to the casing- head and extending 5-1/2 feet above ground level. The marker is properly marked with the well name and thei"l/4 - 1/4 section,· township and range. At the top of the .: collar' .'.t° :~ which the 6'1/2" pipe. isl..welded, the collar or weld has rusted thrOugh .and a White,'.

It has the Jackknife derrick and substructure still standing over it.

The stand pipe with rotary hose still connected is standing on the edge of the floor and tied at the top with only a piece of hemp rope. The kelly joint is on the ground by the side of the road. Much junk and pieces of equipment are scattered around the location. Ther~ is a 9-5/8" casing collar exposed at ground level with a 6" marker welded into it and extending 5-1/2 feet above the surface. No connections on either the marker or the 9-5/8" casing.

ADMINISTRATIVE Discoveries on Federal Leases - Completion of First Producible Well , On abOut October 7, 1959, Standard Oil Company of California made a test on Well S.R.U. 12-27. SW~N~ section 27, T, 8 N., R. 9 W., S.M., Anchorage '028~06. Tested Tertiary sand interval 7630-7650 feet for 7000 to 8000 MCF rate of gas. New gas pool discovery. Well is an extension test drilling to the deeper oil producing HemloCk zone, Swanson River Unit. On October 5 and 8, 1959, Union Oil Company of California ma~e tests on Well No.. 1 (now 14-6), SW~W~ section 6, T. 4 N., R. 11 W., S~.M., Anchorage 0281~2, Kenai Unit. Tested interval 4050-~052 feet (now squeezed off) on October 5, 1959, flowed gas at a 6,600 MCF rate. Teste~ interval ~588-~590 feet, flowed gas at a 6,000 MCF 'rate. This is a new discovery of gas in two zones of the Kenai formation (Tertiary). The electric l°g indicates four zones capable of producing gas. This is the initial test well in the Kenai .Unit. On or about October 22, 1959, Standard 0il Company of California made a test on Well S.R.U. 32-15, SE~SW~N~ section 15, T. 8 N., R. 9 W., S.M., Anchorage 02838~. Tested Hemlock sand intervals 11, 420-11, 4k4 fe~t and 11,454-11,480 feet, flowed 1300 barrels per day of oil rate through a 3/8-inch bottom hole choke, no free water. Perforated additional interval 11,389-11,413 feet and released rig October 24, 1959. This is a development well in the Swanson River Unit outside of Participating Area No. 1. ~nit Agreements and Development Contracts No unit agreements were approved or terminated during the month and no enlargements or contractions were approved. The Katalla-Yakataga No. 2 Development Contract with Richfield Oil Corporation was approved. October 9, 1959 and designated No. 14-08-001-6~17. This contract embraces 571,121 acres.

II -6 Memorandum UNITED STATES DEPARTMENT OF THE INTERIOR GEOLOGICAL SURVEY Anchorage, Alaska Box 259 To: Oil & Gas Supervisor, Los Angeles 1N REPLY REFER To: September 18, 1959 From: Regional Mining Supervisor, Anchorage Subject: Anchorage Gas & Oil, Rosetta #4, Anchorage 019332 This operation was visited yesterday at which time a depth of 1,525: had been reached. Progress was only at about 2 feet per hour and apparently the underlying upper—Cretaceous? has been reached as the rock is a very hard, greenish --cast quartzite and correlates about 200' higher than the Rosetta #3 some 4300= to the south according to Thomas Marshall, geologist on the well. The bit being used is 8 3/411 and about 36 hours is ma:cimum on the bit with mud weight of about 12.8 lb giving best results. A saline flow with gas from the Tertiary coal beds caused considerable difficulty at the start before the addatives were used. Surface shutoff equipment appears in fair condition and in working order. The ria being used is a co-nbi nate on of several purchased in the states and is the best setup used by Anchora;e Gas & Oil thus far. Considerable expense was incurred in pouring a concrete slab because of the boggy nature of the site and much trouble exy.erienced in road building as most of the road from #3 well had to be corduroyed to hold the fill. There is little reason to believe that any better results will be obt�ned`f #4 than in the first three tirel.ls drilled by the CotTlrk7Si_Y. Encl: 1 photo cc:f'-itchell. S[F 1 *{?« .

Snow LGJ1959 U. S. Geological Survey 1012 Bartlett Building215 Vlest Seventh StreetEs� Los Angeles 14, California Dear Mr. Snow: Enclosed is Mr. Tuckerts application for the drill- ing of Anchorage Gas and Oil Development, Inc., Rosetta No. 4 near Houston, Alaska. In accord with our telephone conversation, I have changed the depth of the surface casing from 150 to 300 feet. It is still my opinion that 200 feet of surface casing is adequate provided it is properly cemented. I would like to call your attention to the following facts. I have already pointed out tht we know fro: seismograph shot holes that the surface formation at this location in the Houston shale series is a tough, impervious, nearly horizontal shale which, in my opinion, would effectively hold any pressure if given a cement bond of as little as 50 feet. In our conversation I did not go into detail con- cerning the pressure encountered in Rosetta No. 1 and Rosetta - No. 3. Both of these wells encountered salt water at depths between 700 and 2000 feet in the Houston series. In both cases this water was found to have a pressure slightly in excess of normal hydrostatic head, which was easily over- balanced and contained with 72 pound mud. In Rosetta No. 1 the porous horizon was encountered at 3100 feet in faulted basement rocks. There was no sign of entry into the well from this against a light drilling fluid. In Rosetta No. 3 an extensive faulted or fractured zone was encountered between 1900 and 2000 feet. No entry against (FPIOTDED LTD QM 059 . r Page Two normal mud weight was noted here. At about 3000 feet this well encountered a porous zone in steeply dipping Eocene or Cretaceous beds which flowed salt water after the well was swabbed down, but which did not come in against the light drilling fluid. These three formations are the only ones known to be present in this district. I think it is a virtual certainty that the information obtained from the other two wells may be considered a reliable indication of the hazards to be encountered in No. 4. After talking with you I called Mr. Tucker who confirms the fact that it will be very difficult to get even 100 feet more 10-3/411 casing in Anchorage this summer. If, considering the foregoing, you decd-! that it might be reasonable to allow the proposed well to be drilled with 200 feet of surface pipe, I would certainly appreciate your ad- vising me thereof.
