ASSOCIATED GAS UTILIZATION FROM OIL GATHERING STATION TO GAS PLANT, A LEAN SIGMA EFFORT TO INCREASE GAS PRODUCTION AND ELIMINATE FLARE GAS

摘要

At a time when new economic reserves are extremely difficult to find in Indonesia, it is very important to ensure existing known resources are not wasted. This paper discusses one method to curtail waste and improve profits at a generic processing facility in Sumatra. The associated gas rate at the Oil Gathering Station (OGS) is approximately 1.5 MMSCFD and before this Lean Sigma effort, it was released to the flare stack. OGS has existing connection line for distributing the associated gas to the gas plant, but the operations team couldn’t distributethe associated gas because of H2S contamination. With Chevron’s Lean Sigma production philosophy we were able to solve the H2S issue and increase gas production at the Gas Plant.
