Huber, Sr. Date: 2023.07.26 19:37:59 -06'00' RBDMS JSB 072823 To: Alaska Oil & Gas Conservation Commission From: Ryan Ciolkosz Drilling Engineer Date: July 18, 2023 Re: PBU 14-33A Sundry Request Sundry approval is requested to prepare 14-33A for a CTD sidetrack. Proposed plan for 14-33B Producer: Prior to drilling activities, SL will pull the tubing patch at 10244' MD, drift for whipstock, and E-line will set a 3-1/4" whipstock. Coil will mill window pre-rig. If unable to set the whipstock or mill the window pre-rig, the rig will perform that work. A coil tubing drilling sidetrack will be drilled with the Nabors CDR2 rig. The rig will move in, test BOPE and kill the well. If unable to set whipstock pre-rig, the rig will set the 3-1/4" whipstock. A single string 2.74" window + 10' of formation will be milled. The well will kick off drilling in Ivishak Zone 4. The lateral will continue in Zone 4, 3 and 2 to TD. The proposed sidetrack will be completed with a 2-3/8” 13CR solid liner, cemented in place and selectively perforated post rig (will be perforated with rig if unable to post rig). This completion will completely isolate and abandon the parent Ivishak perfs. This Sundry covers plugging the existing perforations via cement squeeze, liner cement job or liner top packer, if the liner lap pressure test fails (alternate plug placement per 20 AAC 25.112(i)). The following describes the work planned. A wellbore schematic of the current well and proposed sidetrack is attached for reference. Pre-Rig Work - (Estimated to start in July 2023): Pre-Rig Work 1SLPull Tubing Patch, Dummy WS drift to 11680' MD. 2ELSet Whipstock at 11,645' MD 3 Service Coil Mill Window if unit is available 4 Valve Shop Pre-CTD tree work (install sarber spool, PT swab, leak-tight master) 5Valve ShopBleed wellhead pressures down to zero. 6Valve ShopBleed production, flow and GL lines down to zero and blind flange. 7 Opearations Remove wellhouse and level pad.

Sundry 323-407 Post-Rig Work 1 Valve Shop Valve & tree work 2 Slickline Set LTP* (if necessary). Set TBG patch. MIT-IA, Set live GLVs. 3 Service Coil Post rig perforate (~30’) and RPM. * Approved alternate plug placement per 20 AAC 25.112(i) The sundry and permit to drill will be posted in the Operations Cabin of the unit during the window milling operation. Window Milling Fluids Program: x A min EMW of 8.4 ppg KCL. KCl will be used as the primary working fluid and viscous gel sweeps will be used as necessary to keep the hole clean. x The well will be freeze protected with a non-freezable fluid (typically a 60/40 methanol/water mixture) prior to service coil’s departure. x Additionally, all BHA’s will be lubricated and there is no plan to “open hole” a BHA. Disposal: x All Class l & II non-hazardous and RCRA-exempt drilling and completion fluids will go to GNI at DS 4. x Fluids >1% hydrocarbons or flammables must go to GNI. x Fluids >15% solids by volume must go to GNI. Hole Size: x The window and 10’ of formation will be milled/drilled with a 2.74” OD mill. Well Control: x BOP diagram is attached. x AOGCC will be given at least 24-hour notice prior to performing a BOPE function pressure test so that a representative of the commission can witness the test. x Pipe rams, blind rams, CT pack off, and choke manifold will be pressure tested to 250 psi and at least 3,500 psi. x BOPE test results will be recorded in our daily reporting system (Alaska Wells Group Reporting System) and will provide the results to the commission in an approved format within five days of test completion. x BOPE tests will be performed upon arrival (prior to first entry into the well) and at 7 days intervals thereafter. x 10 AAC 25.036 c.4.C requires that a BOPE assembly must include “a firewall to shield accumulators and primary controls”. A variance is requested based on the result of the joint hazop with the AOGCC. For our operation, the primary controls for the BOPE are located in the Operations Cabin of the Coiled Tubing Unit, and the accumulators are located on the backside of the Operations Cabin (opposite side from the well). These are approximately 70' from the well. Hazards: x DS-14 is an H2S pad. H2S reading on 14-33A: 20 ppm on 04/25/2022. x Max H2S recorded on DS-14: 140 ppm. x One fault crossings expected. x Medium lost circulation risk. Reservoir Pressure: x The reservoir pressure is expected to be 3319psi at 8940’ TVDSS (7.1 ppg equivalent). x Maximum expected surface pressure with gas (0.10 psi/ft) to surface is 2425 psi. x A min EMW of 8.4 ppg for this well will be 585 psi over-balance to the reservoir.

Once that is completed a PPROF will be carried out to check the fluid splits and gas production between the two perforated intervals. If the logs prove the deepest perf interval to be a viable zone for a GSO, then a CIBP will be set in the same rig-up. Perforations will be shot from 12870'MD to 12920' MD (regardless of the PPROF results).

Well 14-33 was drilled in October 1983 as a Zn 2 lvishak producer. Diagnostics were performed as the well was approaching MGOR and the upper most perforation interval was found to contribute nearly all of the gas. Three squeeze jobs were performed to successfully abandoned the upper most set of perforations. In 2003 a couple of acid jobs were • pumped and managed to double the gross flow rate, but the additional oil production was minimal. An adperf/ propellent fract stimulation between 12,128' and— 12,144' and was performed in 2004 and the gross flow rate was double; however, it only brought a small oil rate boost. By August 2009, the well was producing at very low rates. Based on a 2008 gas pick, it was decided to shoot 10' of re-perfs uphole in October 2009 between 12095' — 12105' md. These adperfs were seen to pose no significant risk of bringing in uncompetitive gas rates since the last squeeze job successfully isolated a high gas producing area, but oil production was sacrificed. The objective was to re-perforate Zone 26P in hopes of recovering some of the oil rate. However, these re-perfs brought in oil, but also significant gas and made the well uncompetitive. The well is in sound mechanical condition. It passed an MIT-T to 3000 psi (July 2007), MIT-IA to 3000 psi and MIT-OA to 2000 psi (November 2010). The October 2010 Caliper shows the 5W x 4W tubing to be in good condition. With respect to the 7" liner, apart from the perforation intervals, there appears to be no significant areas of cross-sectional wall loss or I.D. restrictions. This well has been shut in for high GOR and there are currently no viable wellwork options. A Coiled Tubing Drilling sidetrack to a Zone 2 target to the east will allow this wellbore to be more effectively utilized and bring value to the field. The sidetrack, 14-33A, is scheduled to be drilled by Nordic 1 starting on February 10th, 2011 targeting lvishak Zone 2. The pre rig work includes setting a thru-tubing whipstock, milling an XN Nipple, and squeezing perforations. With the whipstock set and perforations abandoned, Nordic 1 will mill a window off of the mechanical whipstock allowing a kick off in the Shublik formation. This sidetrack will make a 34 DLS build and turn, land and undulate in Zone 2. Well 14-33A will be completed with 3-3/16" x 2-7/8" solid, cemented and perforated liner. The following describes the planned work. A schematic diagram of the proposed sidetrack is attached for reference.

Mud Program: • Well kill: 8.6 ppg seawater/brine. • Milling/drilling: 8.6 ppg Geo-VIS for milling window and drilling. Disposal: • All Class II drilling and completion fluids and all other Class II wastes will go to Grind & Inject at DS 4. • All Class I wastes will go to Pad 3 for disposal. Hole sizes: 4-1/8" hole: 11,462' and— 12,400' and 3%" hole: 12,400' and— 13,883' and Casing Program: Solid, cemented and perforated completion. • 3-3n6", L-80 6.2 lb/ft TC-II liner 11,050' and— 12,400' and • 2-7/8", L-80 6.5 lb/ft STL liner 12,400' and— 13,883' and • A minimum of 25 bbl of 15.8 ppg Class G cement will be used for liner cementing. (Assuming 4-1/8" and ' 3%" hole sizes as specified above and 20%excess in open hole). • TOC planned at 11,200' md. • If liner lap fails, a liner top packer will be run. Well Control: • BOP diagram is attached. • Pipe rams, blind rams and the CT pack off will be pressure tested to 250 psi and to 3500 psi. / • The annular preventer will be tested to 250 psi and 2500 psi. Directional • See attached directional plan. Maximum planned hole angle is 136° at TD. • Magnetic and inclination surveys will be taken every 30 ft. No gyro will be run. • Distance to nearest property—20,800' md. • Distance to nearest well within pool—875' from 14-03A BHL. ✓ Anti-Collision • No close approach issues. / Logging • MWD directional, Gamma Ray and Resistivity logs will be run over all of the open hole section while drilling. • Open hole triple combo log: Gamma Ray, Resistivity, Density, Neutron, Caliper, Microresistivity, • Cased hole GR/CCUMCNL logs will be run. Hazards • DS 14 is an H2S drill site. H2S levels have reached 100 ppm and more. • The maximum recorded H2S level on DS 14 is 590 ppm on well 14-21 (July 16th, 1995). • Most recent H2S level on 14-33 is 20 ppm recorded on January 16th, 2010. The highest H2S level recorded on 14-33 is 60 ppm recorded on September 13, 2009. • The lost circulation risk in the 14-33A is considered to be medium due to the history of losses in area. Severe losses are not expected. • Two possible faults crossings are expected. The first fault (11,950' md) is uncertain because should have been seen in parent well in Zone 4 but not apparent on well logs or interval thicknesses. The second fault(13,150' md) is near the tip-out of a mapped fault and might not be seen. Reservoir Pressure • The reservoir pressure is estimated to be 3,279 psi at 8,800 TVDss (7.2 ppg equivalent) based on 06- 21B 9/13/2010 SBHP. • Max expected surface pressure with gas(0.10 psi/ft) to surface is 2,400 psi.
