Integrating True Valve Performance Into Gas Lift Design and Troubleshooting

Topics: Artificial lift

Production-system-analysis methods have been used and are currently used for gas lift design and troubleshooting. These methods, however, have been found to be inadequate in several cases for achieving optimum design or troubleshooting problems. To make up for the inadequacy, a new approach has been applied that uses the Valve Performance Clearinghouse (VPC) database. The new approach joins well performance from production-system analysis and true valve performance from the VPC database to form an integrated system performance tool.

Introduction

Qatar Petroleum’s Dukhan field is onshore Qatar approximately 80 km west of Doha. The number of wells in this field requiring artificial-lift assistance has increased over the past few years, and the trend is likely to continue because of reservoir-pressure decline and rising water cut. The availability of gas coupled with compression and distribution-facility availability has made gas lift a natural choice among various artificial-lift methods. The increasing number of wells using gas lift makes gas lift design and troubleshooting key factors in achieving crude-oil-production targets.
