C-11B currently has TxIA communication and fails an MIT-T. The well has a patch in the 4-1/2” tubing, covering a leak in GLM #4 (found in 2006), and new tubing leak below the top patch at 6290’ was found on 8/2/24 with an acoustic LDL. The tubing and IA were loaded and an XX plug was installed in the PTSA nipple at 9,645’ to secure the well. The well passed a CMIT-TxIA to 2500 psi on 7/31/24. This verifies the production casing and packer have integrity. Objective: Pull tubing patch. Circulate well to 1% KCL/seawater. Pull the existing 4-1/2” tubing.

In April of 2021, the toe was isolated by CIBP and the second stage of perfs added. Recently, the second stage of perfs has reached marginal GOR. The goal of this program is to move to the third stage of perforations to return well to economic GOR. Objective: Add 250’ of perfs. Notes On Wellbore Condition: x Last down hole intervention in liner: coiled tubing RIH 04/2021, set CIBP and perforated from 12,520’ – 12,770’ x Gas lift – DPBGL needed to help kick off well Procedure: Service Coil – Mill Plug: 1.MIRU CTU, MU PCE 2.MU 2.3” Milling BHA a.WSS discretion to use a Venturi Burn shoe or junk mill b.Objective is to mill plug and push to bottom 3.RIH loaded well with safelube as needed 4.Mill CIBP at ~12,919’ and push to bottom, POOH Notes x Remote gas monitoring for H2S and LELs are required for Open Hole Deployment Operations x Due to the necessary open hole deployment of Extended Perforating jobs, 24-hour crew and WSS coverage is required. x The well will be killed and monitored before making up the initial perfs guns. This is generally done during the drift/logging run. This will provide guidance as to whether the well will be killed by bullheading or circulating bottoms up throughout the job. If pressure is seen immediately after perforating, it will either be killed by bullheading while POOH or circulating bottoms up through the same port that opened to shear the firing head.

Prepare for deployment of 2”, 6 SPF, 60 degree phasing TCP guns. 2. Confirm well is dead. Bleed any pressure off to return tank. Kill well w/ KWF as needed. Maintain continuous hole fill taking returns to tank until lubricator connection is re-established. a. Fluids man-watch must be performed while deploying perf guns to ensure the well remains killed and there is no excess flow. 3. Perform drill by picking up safety joint with TIW valve and space out before MU guns. Review well control steps with crew prior to breaking lubricator connection and commencing makeup of TCP gun string. Once the safety joint and TIW valve have been spaced out, keep the safety joint/TIW valve readily accessible near the working platform for quick deployment if necessary. a. At the beginning of each job, the crossover/safety joint must be physically MU to the perf guns one time to confirm the threads are compatible. 4. Break lubricator connection at QTS and begin makeup of TCP guns. Constantly monitor fluid rates pumped in and fluid returns out of the well. Fluids man-watch must be performed while deploying perf guns to ensure the well remains killed and there is no excess flow. Table 1: C-11B Proposed Ad-Perf Gun Runs 5.

The goal of this program is to move to next stage of perforations to return well to economic GOR. Objective:Utilize CTU to isolate existing perforations then surface deploy TCP guns with CTU to add new perfs and improve fluid rates. Sundry Procedure (Approval Required to Proceed): Note: The well will be killed and monitored before making up the initial perfs guns. This is generally done during the drift/logging or plug set run. This will provide guidance as to whether the well will be killed by bullheading or circulating bottoms up throughout the job. If pressure is seen immediately after perforating, it will either be killed by bullheading while POOH or circulating bottoms up through the same port that opened to shear the firing head. Coil Tubing 1. MIRU Coiled Tubing Unit and spot ancillary equipment. 2. MU GR/CCL and drift for 2-7/8” CIBP. 3. RIH below target CIBP set depth of ±12,920’ MD 4. Log up, stopping to paint flag. 5.

Confirm well is dead. Bleed any pressure off to returns tank. Kill well w/8.4 ppg 1% KCl or equivalent as needed. Maintain continuous hole fill taking returns to tank until lubricator connection is reestablished. 12. Pickup safety joint and TIW valve and space out before MU guns. Review well control steps with crew prior to breaking lubricator connection and commencing makeup of TCP gun string. Once the safety joint and TIW valve have been spaced out, keep the safety joint/TIW valve readily accessible near the working platform for quick deployment if necessary. 13. Break lubricator connection at QTS and begin makeup of TCP guns per Table 1: C-11B Proposed Ad-Perf Gun Run below.

The well underwent a coil tubing sidetrack in April and is now C-118 (PTD# 2170020). Post rig work to correct the TxIA communication included a gas lift valve change out and resetting a tubing patch to isolate a known leak. The well passed an MIT -T to 2,456psi and OMIT-TxIA to 2,427psi on 07/09/17. The well now has two competent barriers and is reclassified as Operable at this time.

In April 2003 a Rotary sidetrack was performed to C -11A because the original well developed a leak in the casing. In 2012, a 4-1/2" tubing patch was set over GLM #4. This well is currently not competitive and is ready for a sidetrack. Proposed plan: Nabors CDR2 Coiled Tubing Drilling rig will drill a through tubing sidetrack on or around June 1st, 2017. Nabors CDR2 will exit into lower Zone 2A formation in C-1 1A perforations. The sidetrack will target Zone 1 B and 2A reserves. The proposed sidetrack is a 2,940' MD horizontal Ivishak Zone 1 B and 2A producer. The lateral will be completed with a 3-1/2" x 3-1/4" x 2-7/8" L-80 liner which will be cemented and perforated isolating the current Zone 2A perforations.

Hole size: 4.25" Liner Program: • 3-1/2", 9.3#, L-80, STL Solid Liner 9,650' MD —10,475' MD • 3-1/4", 6.6#, L-80, TCII Solid Liner 10,475' MD —10,685' MD • 2-7/8", 6.5# L-80, STL Solid Liner 10,685' MD — 13,425' MD • A minimum of 35.5 — 39.9 bbls of 15.3 ppg cement will be used for liner cementing. (TOC to between 9,800' MD and TOL) • The primary barrier for this operation: a minimum EMW of 8.4 ppg. • A X -over shall be made up to a safety joint including a TIW valve for all tubulars ran in hole. Well Control: • BOP diagram is attached. • Pipe rams, blind rams and the CT pack off will be pressure tested to 250 psi and to 3,500 psi. • The annular preventer will be tested to 250 psi and 3,500 psi. Directional • See attached directional plan. Maximum planned hole angle is 9W. - • Magnetic and inclination surveys will be taken every 30 ft. - • Distance to nearest property — 25,910' • Distance to nearest well within pool — 216' Anti -Collision Failures • C-01 A Fails Major Risk for C-11 B W PO4 Anit-Collision. C-01 A is P&A'd and will be minor risked. • C-30 Fails Major Risk for C-11 B W PO4 Anit-Collision. C-30 is P&A'd and will be minor risked. • C -30A Fails Major Risk for C-11 B WP04 Anit-Collision. C -30A will be shut in and minor risked. Logging • MWD directional, Gamma Ray and Resistivity will be run over all of the open hole section. • Cased hole GR/CCL/RPM logs will be run if cleanout run is needed. Perforating: • 2", 6 spf, pert guns. Hazards • C -Pad is NOT an H2S pad • Low risk of lost circulation and only one planned fault crossings. Reservoir Pressure • The reservoir pressure is expected to be 3,276 psi at 8800' TVDss. (7.16 ppg equivalent). • Maximum expected surface pressure with gas (0.10 psi/ft) to surface is 2,396 psi. • An EMW of 8.4 ppg for this well will provide 567 psi over -balance to the reservoir.
