Logging Report for April 19th., and 20th., 1994, Temp/CCL Logs of EE-3A
Abstract
Two Temperature/Casing-Collar Locator (CCL), logs of EE-3A were performed on April 19th., and 20th., 1994, in an effort to locate fractures where fluid exits the injection wellbore. The first log was run, to serve as background data for comparison to the second log, which was run after a period of injection. The first log was done under static conditions, (with the exceptions of fluid that escaped through the control head during the log, and the continuous venting of the annulus). The log was then repeated the next day, after an approximate six hours of injection, with the Rotojet pump (at a rate of approximately 24 gpm). It was hoped that the short injection period would create anomalies in temperature across fractures, which could be identified by the log. The results however, were less than hoped for. A depth-driven strip chart, recording both load-cell weight, and CCL was run on both logs. Also, it was planed to speed up the logging rate through the zone of 11,700' to 11,790', which was believed to be an area common to premature set-down. After looking at a variety of previously run logs however, it was determined that these set-downs could occur anywhere in themore »
