AbstractIn April 2002, the first retrievable straddle pack-off gas-lift assembly was installed in a Safaniya onshore well, which had been dead due to high water cut since 1993. This gas lift assembly has successfully increased the well production to an average daily liquid production rate of 2600 barrels with 30% water cut. The significant incremental production of 1800 BOPD is regularly contributing to company profit. This paper discusses in detail the new gas lift equipment, principles of operation, installation, and trial test results. The assembly can be installed and retrieved with wireline, eliminating the need for a workover rig. It is equipped with gas lift mandrels to convert them to gas lift without pulling out the tubing. Based on its simplicity, successful operation, and considerable economical impact, there is a vast potential for this technology in Saudi Aramco.
