| Abstract: | The well (WR 45-2D ) is a geothermal development directional well. A keyseat sticking happened at the depth of 586. 97m, which can not be released by running bumper jars. However, the use of washover proved to be very successful. The paper presents in denal the operational difficulties of freeing stuck pipe, technical priciples and effect evalutions. |
