In January 2024 water rate started picking up with oil starting to fall off. Current well rates are similar to flowing periods where the LTP was removed from the well. In May – August, slickline, braided line and coil attempted to recover the LTP without success. In leu of replacing the LTP, we will attempt to squeeze the LTP in place to shut off the large increase in water production. This work is expected to add 94 IOR and payout in 2 months. 9/2013: Post CTD, Slickline install LGLVs and set LTP, tested LTP to 2000 psi Fought scale issues early in well life, in Feb 2014, the water came in without any wellwork. Slickline went out and pushed something to the LTP then spent several days bailing scale until they could pump into the well. 6/22 and 6/23/2014 tests not accurate, something is off and no wellwork was performed at this time, was an initial test after a few months shut in. TIFLs passing 2/13/2015: coil mill/thaw ice plug, bottom at 11380, continue to drift to 13966’ at lockup. Set IBP @ 11,397’ (above all perfs) Establish LLR of 0.5 BPM @ 1300 psi 7/2014: Slickline pulled the LTP, still difficult to POP. Comments around this time report the well as difficult to keep or even get online. Unable to POP 9/2015: SL bailed LTP rubber and slips, pulled IBP IBP and LTP out of well.
