2.0 Mining and Oil and Gas Development <br />to 535 feet bgs. During the surface methane survey in November 2000,20 psi of pressure was still indicated <br />in the 8 5/8-inch annulus. Monitoring with an FID indicated the pressure of organic vapors within the annulus <br />of the 8 5/8-inch and 5 1/2-inch annuli. No irregularities were noted during the drilling of the 28-11. <br />Both wells were plugged and abandoned on October 9 and 10, 2000, by GeoMet. During plugging, soils <br />surrounding the well casing were monitored with an FID. According to the Colorado Oil and Gas <br />Conservation Commission (COGCC) environmental specialist who was present during the plugging, no gas <br />was detected during excavation of soils near the well heads. Methane was reported in the casing (between the <br />8 5/8-inch and 5 1/2-inch annuli) with pressure of 20 psi. No gas was detected near the abandoned wells. <br />Correspondence from the COGCC dated October 25, 2000 stated, "The gas wells are definitely not the source <br />of the methane seep." A copy of this correspondence is included in Appendix A. <br />2006 Methane Monitoring Report (11.02.06).doc 2-2
