APPLICATION OF WIRELINE FISHING TOOLS AND TECHNIQUES TO RESTORE WELL PRODUCTION IN SALAK GEOTHERMAL FIELD, INDONESIA

Abstract

AWI W-5 is one of biggest production wells in the Salak Geothermal Field. It was drilled to a total drilled depth of 9,560 ft. (2,914 m) MD in 2013 as a standard directional well with moderate inclination of 26°. The well was completed as a big hole with a 13-?” production casing and 8-?” perforated production liner. In March 2016, a dummy tool for a Pressure-Temperature-Spinner (PTS) survey was lost in-hole when it hit an obstruction at 1,645 ft. (~504 m) MD. AWI W-5 had to be throttled to prevent materials from the fish flowing to the surface and potentially damaging production facilities. A fishing job was organized in 2017 to retrieve the fish and fully open AWI W-5 into the system. By collaborating with PT. Expro Indonesia, a wireline fishing job was successfully executed and the well was put online with about 182 klbs/hr. (22.9 kg/s) of steam production. In this paper the authors describe the procedures used in executing the wireline fishing job and lessons learned, applicable to future fishing operations.
