Anticipated Surface Pressure:2420 psi (Gas Column Gradient (0.1 psi/ft) to surface) Min ID:3.725” 4-1/2” OtisXN nipple at 10,572’ MD Max Angle:91 deg at 11,451’ MD History K-21 is a natural flow Ivishak producer that was SI in February 2023 after being classified as non-operable. Prior to the integrity issues, K-21 was a fulltime producer making ~400 bopd, 60 bwpd, and 25 MM scfd formation gas. A RWO was considered as a repair option; however, this was deemed uneconomic. So, an IA cement job is being pursued to return K-21 to operable status and bring the well online. K-21 failed a diagnostic warm TIFL on 01/22/23 after DHD was attempting a bleed, but the IA pressure would not bleed down. On 02/10/23, slickline set a TTP and performed a failing MIT-T and CMIT-TxIA. A subsequent LDL on 2/11/23 identified a significant tbg leak @ 6706’ MD. A follow up LDL on 2/22/23 found a PC leak at 6710’ MD. The well does not exhibit OA repressurization. Current Status Not Operable well with PC leak at 6710’ MD and tubing leak at ~6706’ MD. Objective Execute an IA cement repair to seal of the PC and tubing leaks. The proposed TOC in the IA is ~6200’ MD/4977’ TVD which is ~500’ MD above the PC leak at 6710’ MD and tubing leak @ 6706’ MD. 500’ is the general-rule minimum of cement above a PC leak needed for a reliable cement repair. The proposed TOC is ~1932’ MD/1419’ TVD below the SC shoe at 4268’ MD/3558’ TVD and ~275’ MD/203’ TVD deeper than the estimated top of the UG4 marker @ ~5925’ MD/4773’ TVD. Post-job Evaluation o MIT-T and CMIT-TxIA to 2500 psi o CBL to confirm the Top of Cement (TOC) Long-Term Integrity Monitoring o Biennial MIT-T and CMIT-TxIA o Monitor and Record WHPs daily IA Cement for PC/Tbg Leak Well: K-21 Procedural steps Slickline & Fullbore 1. MIT-T targeting 2500 psi and obtain LLR 2. Pull DGLV from 10200’ MD. MIT-T to same pressure obtained in step 1 and obtain LLR. 3. Pull PX plug from ~10337’ MD. 4. Set retrievable plug @ ~6600’ MD. 5. PT tubing to 2500 psi verify tubing integrity above 6600’ MD. 6. Pull retrievable plug. E-Line & Fullbore 1. Set 4-1/2” CBP @ ~10,235’ MD. 2. Pump diesel down the tubing while taking returns up the IA, to confirm circulation path through open pocket at GLM#1. 3. Set 4-1/2” cement retainer ~10,175’ MD Coiled Tubing 1. Sting into cement retainer. 2. Pump down CT: ¾115 bbls diesel (Freeze-protect for IA after the cement job is in place) ¾79 bbls 15.8 ppg Class G cement (5% excess of 7” x 4-1/2” volume from 6200’ – 10200’ MD: 75 BBLS) ¾Chase w/diesel 3. Mill out cement retainer, cement, and CBP. Slickline & Fullbore 1. Set PX plug at 10337’ MD. 2. CBL from ~10200’ MD to ~5000’ to identify TOC in IA. 3. Conduct AOGCC witnessed MIT-T and CMIT-TxIA to 2500 psi. Ensure 24-hour notice provided for AOGCC. 4. Pull PX plug if passing MITs obtained. 5. Set dreamcatcher if needed. E-Line/Slickline (Contingent) 1. If MIT-T above fails, set nipple reducer and plug at 10,337’ MD. 2. Set patch across Tubing leak @ ~6706’ MD. 3. Conduct AOGCC witnessed MIT-T to 2500 psi. 4. Pull plug from nipple reducer. 5. Set dreamcatcher if needed. Well Diagnostics & WIE 1. Update AKIMS and add biennial MIT-T and CMIT TxIA.
