Three well nests of three wells each were <br />plugged with cement from TD to just below the surface. Plugging was performed by Western American <br />Drilling and was supervised by Grcystone staff and Gene Dillisham of the Bureau of Land Management <br />Cement waz mixed in 80 gallon and smaller batches and pumped downhole through 2•inch tubing or tremie <br />pipe. The ttemie 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 oft <br />three feet below the ground and cement was pumped until i[ was one or two feet from the surface. <br />After the cement hardened dirt waz shoveled on top of the site and raked to eliminate large mounds. <br />All trazh was taken off site and disposed of. Wire mesh and rebar protective tapes, used to protect the <br />wellhead, were given to the BLM for their future tue. <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 waz 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 />We11 sampling was done for wells 1, lA, 1B, 1C, 2 and 7; and the samples were taken to Core Labs for <br />chemical analysis. Samples were obtained for all wells except for well 2, which was dry. <br />Thanks for vuur time and a:tcutfon. <br />Sincerely, <br />~~ <br />Jerry H.
