Beasley, R R

Cavern 7 at the Sulphur Mines, Louisiana SPR oil storage site was certified for oil storage on December 17, 1977. The Dowell Sonar caliper survey taken November 29, 1977, indicated a total cavern volume of 5.60 x 10/sup 6/ bbls. The surveys taken December 19, 1979, and June 10, 1981, indicated a total cavern volume of 6.33 x 10/sup 6/ and 6.36 x 10/sup 6/ bbls respectively. This volume increase was a result of continued brining, prior to June 10, 1981, to get brine enrichment for PPG. A well leak test in May 1981 indicated some well leakage. Well workover actions to repair well and wellhead leaks were taken by Texas Brine Corp/Dravo Utility Constructors, Inc. (TBC/DUCI). Testing was restarted in June 1981 using test procedures which were developed in conjunction with the procedures and testing of West Hackberry cavern 6. This report includes a general history of the cavern and a description of the certification testing, analyses, conclusions, and recommendations. The data from cavern 7 and 6 indicate no fluid communication between caverns. Cavern 7 is about 160 ft from the dome edge. The pressure data at maximum operating pressure is comparable to the data from both West Hackberry cavern 6 and Sulphur Mines cavern 6. Therefore, it is considered unlikely that there is a leak to the dome edge. The well test data indicates leaks in the well casing seat area are approximately 100 bbls/yr.
