Three well nests of three wells each were <br />plugged with cement from TD to just below [he surface. Plugging was performed by Western American <br />Drilling and was supervised by Greystone s[aff and Gene Dillisham of the Bureau of Land Management. <br />Cement was mixed in 80 gallon and smaller batches and pumped downhole through 2-inch tubing or tremie <br />pipe. The tremie pipe was lowered to within ten feet of TD and a batch of cement was pumped. Then the <br />pipe was raised up and subsequent batches were mixed and pumped. The PVC casing was broken off <br />three feet below the ground and cement was pumped until it was one or two feet from the surface. <br />After the cement hardened dirt was shoveled on top of the site and raked to eliminate large mounds. <br />All trash was taken off site and disposed of. Wire mesh and rebar protective cages, used to protect the <br />wellhead, were given to the BLM for their future use. <br />A well abandonment report is attached for your review and approval. <br />Reseeding also occurred during this period on a bald area on the top of the ridge between Ponds #002 <br />and #003. The ground was hoed and broken in order to trap seeds and to prevent removal by surface <br />runoff and strong winds. Approximately 45 pounds of the approved reclamation seed mix was applied. <br />Well sampling was done for wells 1, lA, 1B, 1C, 2 and 7; and the samples were [aken to Core Labs for <br />chemical analysis, Samples were obtained Cor all wells except for well 2, which was dry, <br />-Ilian'~s for yuu: lime and atteuiiun. <br />Sincerely, <br />Jerry H.
