All, Producer 17-22 (PTD#2010190)was made Under Evaluation on 5/03/18 for having sustained IA casing pressure above NOL. On 6/1/18 slickline ran a leak detection log and confirmed a tubing leak at 8,226'. The well was left secured with a tubing tail plug and passed a CMIT-TxIA to 2,496psi on 5/30/18. At this time the well is reclassified as Not Operable and will remain secured. The production engineer will evaluate for a repair plan.

Slickline changed out the screened orifice on 05/22/18 but the well subsequently failed a cold TIFL on 05/24 and a warm TIFL on 05/26.Slickline was delayed in rigging back up on the well due to the proximity of a coil tubing acid treatment nearby. On 05/30/18 Slickline set a TTP and obtained a passing CMIT-TxIA to 2496 psi, but could not obtain a passing MIT-T.The Slickline unit is still rigged up on the well and is currently troubleshooting the source of the tubing leak.The Under Evaluation clock will be extended 14 days to allow Slickline to finish the diagnostic work and repair the well or leave it secured with the TTP.

Ensure that all TAM equip is compatible w/other equipment on location and that all handling tools are on location. C. Actively participate in pre-job planning meeting. Note that the casing must be landed on the mandrel hanger(not emergency slips) for this procedure to be valid w/out rigging up a false rotary table. D. For a landing tool w/LH Acme running threads, modify the landing joint to consist of a 24.5' lower section and a 10' top section w/a MBTC connection. When landed the top of the lower section will be above above the flowline but below the rotary slip bowl. This will allow cement returns(and any carried gravel) to pass directly to the flowline. E.
