Unocal Corporation ("Unocal") submitted an application, dated April 26, 2001, requesting that the Alaska Oil and Gas Conservation Commission ("Commission") issue a freshwater aquifer exemption for purposes of Class II disposal in the Ivan River IRU 14-31 well. 2. Additional infonnation supporting the request for the freshwater aquifer exemption and Class II disposal in Well IRU 14-31 was received by correspondence dated June 22, 2001 and by sundry notice and reports dated June 13,2001. 3. Notice of opportunity for public hearing was published in the Anchorage Daily News and Peninsula Clarion on May 14, 2001 in accordance with 20 AAC 25.540. 4. The Commission has jurisdiction in this matter under AS 31.05.030(h), 20 AAC25.440, and 40 CFR 147, Subpart C - Alaska. 5. The Commission did not receive any protest or a request for a public hearing. 6. The Commission submitted a copy of Unocal's aquifer exemption application to the U.S. Environmental Protection Agency Region 10 ("EP A Region 10") on May 1 0, 2001 and a copy of the proposed order on July 17, 2001, in accordance with Section 14 of the November 22, 1991 Memorandum of Agreement between EP A Region 10 and the Commission. Aquifer Exemption Order Ñ7" 6 July 23, 2001 Page 2 of 4 -<' 7. EP A Region 10 did not obj ect to the Aquifer Exemption Order for the Ivan River IRU 14-31 well. FINDINGS: 1. By correspondence dated May 16, 2001 Unocal requested authorization from the Commission to dispose of Class II oil field waste fluids by underground injection into Upper Sterling Formation sandstones and conglomerates in well IRU 14-31, located in the Ivan River Field, Matanuska-Susitna Borough, Alaska. 2. Unocal is the operator of the Ivan River Field. There are no other operators within a 12 mile radius of the proposed disposal injection well. 3. Unocal proposes to conduct disposal operations in the Well IRU 14-31 between 3145' and 3420' measured depth (MD). 4. In order to accommodate the proposed Ivan River Field disposal injection operations Unocal has requested exemption of all fresh water aquifers within a 12 mile radius and below 2500' MD in well IRU 14-31. 5. Wireline log analytical techniques, which comply with EP A recommended methods as described in "Survey of Methods to Determine Total Dissolved Solids Concentrations", (KED A Project No. 30-956), were used to characterize formation water total dissolved solids content in the IRU 14-31 well. 6. Wireline log analysis of the IRU 14-31 well demonstrates that the water total dissolved solids content in the aquifers requested for exemption by Unocal are all greater than 4,000 parts per million from 2500' to 3420' MD. 7. Ivan River Unit is located in the Susitna Flats State Game Refuge where there are no permanent residences. 8. With the present completion in IRU 14-31, a cement retainer and cement plug restricts access to depths deeper than 3225'MD. Current perforations for planned disposal are between 3189' and 3209' MD. Should additional perforated intervals become necessary, U nocal will seek additional authorizations from the Commission. 9. Unocal requests an exemption for 12 mi. radius surrounding the IRU 14-31 wellbore. Unocal requests a 12 mile radius to allow for the possible permitting of a second disposal well near the IRU 14-31 surface location. 10.IRU 14-31 was drilled to a depth of 10,958' MD. IRU 14-31 includes 20" casing to 401' MD, 10 %" casing to 2018' MD, and 7" casing to 7018' MD. The well Page 2 of 4 - Aquifer Exemption Order No.6 July 23, 2001 Page 3 of 4 ~~ was suspended on August 18, 1975 as 7" casing and drill string was cemented in place with cement extending from 3510' to 9937' MD. A cement plug was placed from 3350-3508' MD with a retainer set at 3225' MD. In 1993 Unocal received Commission approval to run 2 7/8" tubing to 2982' MD with an isolation packer at 2903' MD. 11. The nearest drinking water wells are two freshwater wells. completed at approximately 200' MD on the Ivan River production pad. 12. A segmented cement bond log was run in the 7" ofIRU 14-31 on Jan 31,1993. This log shows adequate cement to prevent movement of fluids above the proposed injection intervals. 13. The wells within ~ mile perimeter were reviewed for mechanical integrity. Unocal submitted records of cementing and mechanical details for these wells. All wells appear to be sufficiently cased/cemented, although IRU 13-31 will require additional monitoring due to its close proximity to the proposed injector. 14. Operations will be manned during injection into IRU 14-31. All annulus pressures of wells within the ~ mile radius will be checked and recorded prior to and after each injection cycle. The existing IRU 13-31 Glycol High Level Alarm will also alarm at the injection pump so that the injection pump operator can immediately shut down the pump in the event that communication developed to IRU 13-31. In that event, injection would not be re-initiated until it was determined that safe operations could continue and with Commission approval. 15. The Commission's authority to act in this matter is embodied in 40 CFR 147 Subpart C, the Alaska Oil and Gas Conservation Act (AS 31.05), and the Alaska Administrative Code (20 AAC 25.005 through 20 AAC 25.990). 16. Aquifer exemptions exist at similar depths in the Lewis River Unit to the north and at Beluga River Unit and North Cook Inlet Units to the south. Freshwater used at Beluga River also comes from shallow wells completed at depths of approximately 200' MD. CONCLUSIONS: 1. Those portions of freshwater aquifers occurring within a ~ mile radius and between 2500' and 3420' MD in the IRU 14-31 well do not currently serve as a source of drinking water. 2. Sources of drinking water exist at shallow intervals in the area. Page 3 of4 Aquifer Exemption Order N~ 6 July 23, 2001 Page 4 of4 '-' 3. The total dissolved solids content of the water occurring within a 'i'2 mile radius and between 2500' and 3420' MD in the IRU 14-31 well is greater than 3000 parts per million and is not reasonably expected to supply a public water system. 4. Those portions of freshwater aquifers occurring within a 'i'2 mile radius and between 2500' and 3420' MD in the IRU 14-31 well is not reasonably expected to serve as an underground source of drinking water. 5. Those freshwater aquifers occurring within a 'i'2 mile radius and between 2500' and 3420' MD in the IRU 14-31 well qualify for designation as exempt freshwater aquifers under 20 AAC 25.440. 6. The stratigraphic sequence present in Ivan River and maintenance of mechanical integrity of the IRU 14-31 well will prevent movement of fluids into underground sources of drinking water. NOW, THEREFORE, IT IS ORDERED THAT the portions of freshwater aquifers lying between 2500' and 3420' MD in Unocal's Ivan River well IRU 14-31 and within a one-half ('i'2) mile radius of the well are exempt for purposes of Class II underground injection activities. DONE at Anchorage, Alaska and dated July 23,2001. ~~ ¡,AI ~ Julie M. Heusser, Commissioner AS 31.05.080 provides that within 20 days after receipt of written notice of the entry of an order, a person affected by it may file with thc Commission an application for rehearing. A request for rehearing must be received by 4:30 PM on the 23rd day following the date of the order, or next working day if a holiday or weekend, to be timely filed. The Commission shall grant or refuse the application in whole or in part within 10 days. The Commission can refuse an application by not acting on it within the 10-day period. An affected person has 30 days from the date the Commission refuses the application or mails (or otherwise distributes) an order upon rehearing, both being the final order of the Commission, to appeal the decision to Superior Court. Where a request for reheming is denied by nonaction of the Commission, the 30-day period for appeal to Superior Court runs from the date on which the request is deemed denied (i.e., 10th day after the application for rehearing was filed).

The attached drafts need the water salinity and geologic info, prior injection into this strata and correct legal lingo. I'm sure you'll have a lot of changes, but hope this helps you. Unocal intends to use this site in early September. Wendy you indicated that the EP A needs 45 days review, so I guess the AEO needs to be out by Mid July. Bottom line, from an engineering standpoint, the disposal into 14-31 should be approved, assuming they have provided all the infonnation you need to proceed, Wendy from your standpoint. My findings are in the attached drafts. I am suggesting a few requirements, restrictions differing from their request. Following summarizes my concerns, and suggested action. I have reviewed completions of all wells, and the fracture model they provided. The fracture modeling in very pessimistic cases would not see extension of fractures vertically into strata at 2500' (2350'TVD). It would be confined by the 14' shale at 2945'. I am satisfied with the vertical analysis. However, it may be a different story laterally. Their modeled fracture half-length exceeds that of the proximity of the closest well 14-31. The proximity of the injection well to IRU 13-31 at 114' frOln IRU 14-31 has given me a little concern (perhaps unwarrented) along with some of the specifics about the 13-31. Well 13-31 was drilled in 1992-93. The 9 5/8" is well cemented (excellent) from shoe to 2560'- so no problem up the 9 5/8" backside. The 9 5/8" had significant drilling based wear at the 1500' mark based upon caliper in 1993. Unocal wanted to use this as an annular disposal well (into the same zone we're talking about here). Because of the weak spot, they were limited to 1800 psi at surface (80% of burst) and could not get away at this pressure. This is about 3400 psi at the shoe (with 10.8 ppg mud), which is really close to the fracturing pressure downhole. 7" was run to 10,350' where it became stuck. The 7" was cemented with top of cement at SODa'. They then started disposal, and the rate droped to less than 1/4 BPM with the lower pressure limit imposed by the weak spot in 9 5/8". Unocal requested a change in operations to cement the annular space between the 9 5/8" and 7" from 2590-surface through the stage collar at 2793'. This would allow annular injection through the 7", into the stage collar, and then out the lower 7" x 9 5/8" annulus. On 12/8, they retested stage collar with retrievable set above, then below stage collar. They found the collar leaked @ 2500psi but casing held at 1500 psi with 10#/gal mud. We don't have a CBL after 2nd cement jobs but calculations indicate it is more than sufficient for cementing of the 7"x9 5/8" with a total of 1697 lof2 712/01 9:07 AM Ivan River AEO and 010 .~ sax. Now, very worst case scenario is if the fracture hits the 7" of 13-31, travels up the 7"x 9 5/8" annulus to the DV and goes into that weak spot of 9 5/8". With all the cement that was pumped, this is very unlikely. While it is a remote possiblility that they would see a problem at the offset wells, I recommend a few precautions: · They have asked to be able to inject at up to 3300 psi at surface. rIll recommend the lllax pressure should lowered to 2800 psi. They have been able to demonstrate that they can get fluids away (2-5 BPM) at that pressure. This would help minimize potential of overpressuring 9 5/8" in 13 - 31, with friction drop and head. · Unocal should test the mechanical integrity of the 7" casing in Well 13-31 as well as the disposal well. · I recommend Unocal provide more depth on annular lllonitoring in the disposal and offset wens, the potential hazards, and appropriate procedures. Unocal provided a proposed monitoring program for 13-31 which would monitor the glycol tank level. Iflevel goes to high, it will allann at both the 13-31 location and 14-31, and an automatic si of the 13-31 annulus would occur, and they would manually SI 14-31. I'm not fully comfortable that this is the correct path, and don't have enough infonnation on these surface facilities to make a judgement. We should go ahead with the AEO and DID, but just require that they provide this infonnation before injection starts. I haven't run these proposed restrictions by Brandenburg and others at Unocal. The worst case scenarios I have mentioned here are remote, and I am not opposed to you taking them out. Hope this is sufficient. I will give you a call next week and see how it is going.

Commìssiol Anchorage RE: Request for an Aquifer Exemption for the Upper Sterling Formation Ivan River Field, Ivan River Well 14-31, Section 1, T13N, R9W, S.M. Matanuska Borough, Alaska Dear Ms. Taylor: My staff has reviewed the application by Unocal Corporation for an Aquifer Exemption of the Upper Sterling River Formation in the vicinity of the Ivan River Well 14-31 in the Ivan River Field. The Alaska Oil and Gas Conservation Comn1ission (AOGCC) permitted Class II disposal well is located in Section I, T 13N, R9W, S.M. Matanuska Borough, Alaska. The Ivan River Well 14- 3 1 will be llsed to dispose of Class II oilfield waste fluids. Injection will be into the Upper Sterling Formation below a depth of 2500 feet measured depth (MD) and the injected t1uids are to remain below that depth. Your tindings and our review indicate the Upper Sterling Formation in the vicinity of the well contains t1uids with a total dissolved solids (TDS) content of over 4,000 mg/litcr. The applicant has supplied inforn1ation indicating the oil and gas platform is located in the Susitna Flats State Game Refuge, there are no known permanent residents in the area which is also very ren10te from all existing communities. In fact, the only development in the area other than oil and gas developn1ent arc "duck shacks" seasonally used by hunters. Evidence submitted by the applicant also shows the surface is commonly underlain by over 1000 feet of unconsolidated sediments containing available intervals of potentially fresh water. The applicant reports potential users of fresh water in the area would rather target a surface collection system or one of the shallow aquifers. The oil and gas platform drinking water is presently supplied fron1 shallow alluvial wells from a depth of approxin1ately 200 feet below the surface. The applicant further reports it would be economically impracticable to utilize the Upper Sterling Formation as a source of drinking water due to the added expenses to recover the water from the saline aquifer and to treat the water to drinkable limits. o Printed on Recycled Paper --- '---' 2 Based your fmdings and our review, the Environmental Protection Agency (EP A) has determined that the Upper Sterling Formation within Y2 mile of the Ivan River Well 14-31 well is not reasonably expected to supply water to a public water system. Because of the absence of comments during the public comment period, EP A assunles that the proposed exemption is consistent with the Alaska ground water standards. The ground water standards are contained within the Alaska Water Quality Standards (18AAC-70.050) (Katy McKemey, ADEC). EP A does not object to an exemption for the Upper Sterling Formation within Y2 mile of the well. As a result of this exemption, the Upper Sterling Formation within Y2 mile of the Ivan River 14-31 Class II disposal well will no longer be - - defmed as an underground source of drinking water (USDW). The exemption is considered to be a minor modification of the AOGCC's program for the regulation of Class II injection wells under Section 1425 of the Safe Drinking Water Act, as defined by Underground Injection Control (UIC) Progranl Guidance 34 and 40 CFR 145.32. Thank you for the opportunity to review and provide comments on this proposal.

In accordance with 20 MC 25.440, Union Oil Company of California dba Unocal requests approval of a Freshwater Aquifer Exemption for all aquifers below 2500 feet, for an areal extent of % mile radius around IRU Well 14-31. As detailed in the attached geologic report, the aquifers below 2500 feet meet the criteria for exemption as specified in both State and Federal regulations (20 MC 25.440 and 40 CFR 146.4). Salinity of formation water at this depth is greater than 4,000 ppm NaCI. This request is in support of planned subsurface injection activities that would occur in IRU Well 14-31 in the injection interval between 3145 - 3420 feet. Accordingly, requests for an Injection Order and approval to convert IRU 14- 31 to a Class II Injector will follow. If approved, RCRA exempt wastes generated by workover and drilling activity in will be disposed. A Sundry notice to test well injectivity is also being prepared for Commission approval. Areal Considerations Summer 2001 well work might generate 20,000 - 30,000 barrels of waste. Ongoing disposal of produced water might generate +/- 100,000 barrels for disposal at this site. These volumes would create a waste plume that could range from 80 -150 feet surrounding the injection point. Since there is little, or no, natural pressure gradient in the disposal zone, and since there is no other subsurface injection in the area, the plume should not migrate laterally after disposal ceases. Accordingly, an aquifer exemption is requested for an area encompassing % mile around the injection point, shown on Exhibit 3 at the top of the injection interval (3145 feet in Well 14-31). Background of the Area, Facilities, and Current Operations The geographical area in which application is made lies immediately west of the Susitna River. The terrain is a featureless wetland which in 1976 was included in the Susitna Flats State Game Refuge. Predating establishment of the Refuge, lands were leased for oil and gas exploration, development, and production, and operations under these leases have taken place and continued compatibly. Regional maps, Exhibits 1 and 2, show the location of the various oil and gas fields and unit boundaries. The only improvements in the area, other than those incident to oil and gas operations, are a number of "duck shacks" seasonally used by duck hunters. There are no known permanent residents in the area, nor should they be expected because of the marshy conditions stretching for miles and the designation of the lands as a game refuge. In addition to the unsuitability of the surface terrain for "people" uses and its designation as a game refuge, the evidence submitted by Unocal shows some 1000 feet of ~ '-=-' unconsolidated sediments containing available intervals of potentially fresh water. Potential users of drinking water in the area would rather target a surface collection system or one of the shallow aquifers. At the Ivan River production pad there are two freshwater wells completed at approximately 200 feet. These are used intermittently when well work is required. It would be economically impractical to recover water from the underlying saline aquifers and put it through a desalinization process for human consumption. Comparative Considerations Aquifer exemptions exist at similar depths in the Lewis River Unit to the north and at Beluga River Unit and North Cook Inlet Unit to the South. Fresh water used for human consumption and other purposes at Beluga River comes from shallow wells completed at approximately 200 feet. The Tyonek platform in North Cook Inlet Unit uses a seawater distillation unit and sometimes supplements this with freshwater brought to the platform by boat. There are no plans to use underlying aquifers as a source of drinking water at the platform. "-' "-- Geologic Report for Ivan River Unit 14-31 Injection Permit Application Exhibit 1 - Regional Map Exhibit 2 - Regional Map Exhibit 3 - Well Location Map Exhibit 4 - Cross Section Exhibit 5 -IRU 14-31 Log Exhibit 6 - Resistivity of Equivalent Solutions Exhibit 7 - Rw vs. Rweq Chart This report describes the geology of the area surrounding the IRU 14-31 well and provides geologic evidence in support of UNOCAL's application for a freshwater aquifer exemption. The index maps presented on Exhibits 1 and 2 show the location of the Ivan River Unit and surrounding gas fields (Beluga, Pretty Creek, Stump Lake, and Lewis River). The structure and stratigraphy of the geologic units underlying this area is described below. The Ivan River structure is a broad doubly plunging anticline. At the shallower depths that are the focus of this application, the structure is nearly flat, and it is unfaulted. A thick layer of glacial outwash deposits covers the surface. These sediments were deposited by high-energy braided streams and are comprised of bedload sands and gravels, interlayered with low permeability floodplain deposits consisting of clay-rich sandy silts, and shales. The thickness of these glacial deposits is difficult to determine due to their lithologic similarity to the underlying Sterling Formation, although they appear to extend down to a depth of approximately 3100 feet. The sediments of the Sterling Formation were deposited by a meander belt stream system (Hayes et. aI., 1976). The resulting deposits generally include fining-upward sequences of bedload conglomerates overlain by thick quartz-rich sands which are often capped by flood plain siltstones and mudstones. Because deposition was rapid as the meanders migrated across the flood plain, the siltstones and mudstones were not completely eroded. The result of this process is extensive lateral continuity of both the coarse grained and fine grained lithologies. Coals are also common and represent the vegetative cover of abandoned meanders. The effective winnowing of the high-energy Page 1 of 4 .~ ---- channel deposits and their relatively poor consolidation creates excellent porosity and permeability in many of the Sterling Formation sands. This formation is approximately 2000' thick at the Ivan River Field. Underlying the Sterling Formation are the meander belt and braided stream deposits of the Beluga Formation. This unit is comprised of fine grained sandstones, siltstones and coals, with minor conglomerates. Due to the nature of their deposition, the sands in the Beluga are much thinner than those of the Sterling Formation and they are relatively limited in lateral extent. These sands are also relatively rich in clay which decreases their permeability. The thickness of the Beluga Formation at Ivan River Field is approximately 2600' . Underlying the Beluga formation is the Tyonek Formation. Like the Sterling Formation, these sediments were deposited in a meander belt stream system and consist of laterally extensive sandstones, siltstones, shales and coals. The Tyonek Formation is over 4500' thick at Ivan River. The location of existing wells at Ivan River field is shown on Exhibit 3. These wells (with the exception of IRU 14-31 and IRU 23-12) currently produce gas from the Tyonek formation at a vertical depth of 7800' to 7900' below sea level (BSL). Injection is proposed in the IRU 14-31 well into coarse grained glacial outwash sands and gravel at measured depths of 3145'-3420' (2821'-3028'BSL). These sands are colored yellow on the dual induction log presented as Exhibit 4 and they are colored orange adjacent to the IRU 14-31 wellbore on the cross section presented as Exhibit 5. On the right side of the dual induction log (Exhibit 4), two resistivity logs are presented: 1) the laterolog-8 (RLL8) which is presented as a solid curve and 2) the deep induction log (R1LD) which is presented as a bold dashed curve. The laterolog-8 device measures the resistivity of tne formation near the wellbore where the formation has been flushed by the drilling fluid. The deep induction device measures the resistivity of the formation at greater distances from the well bore (approximately 6') where the formation has not been affected by the drilling fluid. Sands on this log are easily recognized by increases in the resistivity curves while finer grained clay-rich sands and silts are indicated by lower resistivity values (colored orange on Exhibit 4). The sands targeted for injection are overlain by an impermeable twelve-foot-thick confining shale or clay (colored grey-brown on Exhibit 4 and Exhibit 5). These sands and the overlying confining shale can also be recognized on the electric logs of IRU 44-1 and IRU 23-12, indicating that they are laterally extensive units (Exhibit 5). Because this confining shale is laterally extensive and impermeable, it can be expected to serve as an excellent barrier to vertical migration of injected fluids. The equivalent salinity of the formation water at various depths in the IRU 14-31 well is shown on Table 1. The method used for the determination of formation water salinity is Page 2 of 4 ~-~ '- described in Appendix A. The calculated salinity of the formation water near the top and near the bottom of the zone targeted for injection is 6100 ppm and 9230 ppm respectively. This is well above the 3000 ppm maximum acceptable limit for fresh water. The deepest sand that contains fresh water (below 3000 ppm NaCI) is at 2297' MD (-2145 BSL). In addition to the 12' of primary confining shale, there are 280 net vertical feet of impermeable silt and clay-rich sand (colored brown on Exhibit 4) between the proposed injection zone and the deepest fresh-water sand. The sudden changes in formation water salinities with depth suggests that the sands are hydraulically isolated by the interlayered silts and clays (Exhibit 4). If they were not hydraulically isolated, the salinities of the sands would be more similar. Although the IRU 14-31 well was not logged above 2038' MD, the adjacent IRU 44-1 well was logged at shallow depths. The IRU 44-1 logs show very high resistivity readings (in excess of 100 ohmm) above 2000' MD indicating that fresh water is present at these shallow depths. Although Ivan River Field is currently remote from even small population centers, fresh water at these shallow depths can (and is) easily be tapped by inexpensive wells should the need arise. With continuous recharge from precipitation and snow-melt runoff, this supply of freshwater is virtually limitless. Thus, it would be economically impractical to attempt recovery of drinking water from the underlying saltwater sands.

Page 4 of 4 - '- APPENDIX A Using standard log analysis techniques, the equivalent salinity of formation water (in ppm NaGI) can be estimated in two ways: 1) the Rwa method and 2) the SP method. Because the SP log lacks any systematic character across the interval' of interest in these wells, only the Rwa method can be applied across the entire section. This technique is based on the following relationships: Rwa = R/F where F = 0.62/[2·15 (Humble Formula) Rwa Apparent formation fluid resistivity Rt True formation resistivity F Formation resistivity factor f Porosity For a given sand, if porosity, formation temperature (Tfm) and apparent fluid resistivity are known, it is possible to estimate equivalent salinity (in ppm NaGI). It is assumed that NaGI is the dominant salt where specific knowledge of the actual fluid chemistry is unavailable. Resistivity, read from the deep induction curve (R1LD), is assumed to be the best approximation of true resistivity of the formation beyond the zone that was invaded by drilling fluids at the time of logging. The formation resistivity factor eliminates the effect of the rock itself from the resistivity measurement so that the resulting value (Rwa) represents only the contained fluid. Rwa values, when corrected for temperature, can be used to estimate salinity with a standard nomograph or set of equations (Exhibit 6; Atlas Wireline Services, 1988). The salinities presented in Table 1 were calculated by calibrating to an equivalent resistivity at 75°F and then solving for salinity, although similar results may be obtained by using a straight line through any value for Rwa (on the right stem) and the corresponding formation temperature (on the left stem). This line will intersect the equivalent salinity (on the middle stem). Since determination of salinity in this manner involves an exponential of porosity (see Humble formula above), a small error in porosity is reflected as a much larger error in the calculated salinity. In the IRU 14-31 well, a formation density log was used in conjunction Page A-1 of 3 - with a neutron log to determine porosity. This was done by using the standard practice of averaging the porosity values indicated by the two curves for any given depth (Asquith and Gibson, 1982). An alternative method is to simply use the porosity value indicated by the density tool alone, however using this method in the I RU 14-31 well produces unrealistically high salinities due to the low porosities indicated by the density curve. Thus, the salinity values listed in Table 1 are conservative and could be much higher. Although the SP method of determining water salinities cannot be applied to most of the section due to the lack of character of the SP curve, an attempt was made to apply this method to the sand at 2990'. The SP method is based on the following relationship: Essp = -Kclog(Rmfeq/Rweq) Where Essp = Static SP which is measured as the amount of SP curve deflection from the shale baseline Kc = 61 + 0.133 Tf Rmfeq = the equivalent mud filtrate resistivity if it were a pure NaCI solution. This value is calculated by multiplying the true mud filtrate resistivity (Rmf) at formation temperature by 0.85. Rweq = the equivalent water resistivity if it were a pure NaCI solution. In IRU 14-31, the Essp = -28 mv, Kc = 61 + 0.133(67) = 69.9, and Rmf = 2.34 ohmm at 64 degrees. This equates to 2.2 ohmm at formation temperture of 67 degrees, resulting in Rmfeq of 2.20hmm(0.85) = 1.91 ohmm. Inserting these values into the equation above and solving for Rweq results in a value of 0.76 ohmm. Using the chart shown in Exhibit 7 (Schlumberger, 1989), results in a Rw value of approximately 1.1 ohmm. This is very close the 1.0 ohmm value determined for Rw from the Rwa method, and it indicates that the application of the Humble equation to these sands results in valid Rw values and salinities. Porosities, calculated as described above, within the coarse-grained sands of the upper Sterling Formation range from 140/0 to 200/0 (Table 1). Porosities in the finer- grained clay- rich sands and silts (colored brown on Exhibit 4) are considerably higher at 330/0 to 36°k; however, this does not indicate that permeabilities in these intervals are higher. In fact, the opposite is true. The higher porosities in the clay-rich sands are caused by interstitial water trapped between the unconsolidated microscopic clay particles. However, these interstitial pores are too small to allow fluid to pass through, making the intervals relatively impermeable. Likewise, the porosity in the twelve-foot-thick confining shale or clay Page A-2 of 3 -' (colored grey on Exhibit 4) is 390/0. This high porosity value is caused by the very high concentration of clay particles that are trapping interstitial water and effectively blocking the movement of fluid. The formation temperatures that were used were based on a thermal gradient of 1.15°F/10Q'. This gradient was determined using a linear interpolation between mean surface temperature (MST; 35°F for the Cook Inlet region) and the maximum recorded temperature downhole (Tmax). The latter is usually measured at TO after the temperature of the mud in the borehole has equilibrated to the temperature of the surrounding formation. In the case of IRU 14-31 this temperature was found to be 136°F at 10,794' MO or 8739' BGL. This results in a thermal gradient (TG) as follows: TG = (Tmax - MST)/Oepth BGU100' = (136°F - 35°F)/8739'/1 00' = 1.156°F/100' Page A-3 of 3 353700 265000~~ 26'l5Ø0Ø~ 26'l020Ø~ 353700 360,000 \/ \ \ \ I / IR 41-1 / / / I ~van I I I I ~XHIBIT 3 WEStSIDE COOK IN LET UN IT BOUNDARY IVÀN RIVERAREA PROPOSEJIR14..31ilNJEc)'FÎON 35 00 3600Ø0 R11 I- 15 N " I,~",,·, ......... ................. < ........ ....................... . ....
