tripped in with open ended with 2 3/8 inch drill pipe to a depth of 1,776 feet and flushed the <br />4.5 inch casing with fresh water to prepare it for cementing. Meeker Sand and Gravel arrived <br />with 7 cubic yards of 15 ppg Portland II /V neat cement. RRWS pumped 3.5 yards of cement, <br />and then pulled 34 joints of pipe. This brought the calculated top of cement to 1,086 feet BGL. <br />The tremie pipe and pump were flushed with freshwater. A second batch of approximately 3 <br />cubic yards was pumped downhole. Cement returns were noted at surface, and discharged to <br />the pit. RRWS pulled all but two joints of tremie pipe and flushed with fresh water. A second <br />truck from Meeker Sand and Gravel arrived with 3 cubic yards of 15 ppg neat cement. <br />Approximately 1.5 cubic yards was pumped down hole and circulated to surface. Good cement <br />returns were discharged to the pit, and circulation was maintained until all fresh water was <br />displaced and the returns consisted of just cement. The hole took approximately 6.5 yards to <br />cement, including displacement through the perforations. The two remaining tremie pipe <br />joints were pulled, and top of cement was noted at four feet BGL. RRWS rigged down. <br />Conclusion <br />The Natural Soda, Inc. Dissolution Surface monitoring well 90 -2 was successfully plugged and <br />abandoned on October 19, 2013. A total of approximately 6.5 cubic yards (approximately 163 <br />sacks) of Portland Type II /V neat cement were pumped down hole to plug well from a depth of <br />1,800 feet (CIBP) to 4 feet below ground level. Approximately 1 cubic yard exited the <br />perforations into the casing annulus. The intermediate casing was cut off below surface, and a <br />dry hole marker was welded onto the well head prior to reclamation of the pad. <br />Daub & Associates, Inc.
