Southern California Gas Company has proposed to rework UGS well Miller 8, API #04-083-03411. The well is located in the La Goleta Gas Storage field in Santa Barbara County. The rework would punch and inject resin into the annulus to mitigate pressure buildup and inspect the integrity of the well. The work would include pulling the 3-1/2” completion tubing and associated BHA accessories, cleaning out the liner to bottom (if possible), running diagnostic logs to evaluate source(s) of annular pressure buildup in the 8-5/8” x 6-5/8” annulus, running a Punch-and-Inject tool, and injecting resin into the annulus. After resin injection, an assessment of the injection well would involve running inspection logs to evaluate the 6-5/8” production casing and pressure testing the production casing to meet the minimum pressure requirement (2140 psi). New 3- 1/2” tubing (to include a SSSV, a production packer and profile nipples) would be installed in the well. The well would be returned to service, and a noise/temp survey would be run to verify no communication from the storage zone to the production casing x tubing annulus (6-5/8” x 3-1/2”). Temporary equipment such as pumps and return bins would be needed. No permanent facilities would be constructed. No expansion of associated facilities would be required. Waste materials would be properly disposed of as nonhazardous or hazardous waste, as appropriate, at a facility licensed to accept the waste. The proposed work is expected to last between 45 and 60 days, with variance depending on the amount of fill and/or sand that the operator would need to cleanout in the wellbore, and the amount of resin injection intervals to complete as determined by log interpretations and vendor recommendations.
