Abstract

In the upstream oil and gas industry, at plateau production period, well intervention activity is important to maintain the production level. In PT. Total E&P Indonesie, well intervention has contributed approximately 23% average per year of the whole oil and gas production. It is important to evaluate the well intervention productivity for continuously improvement. This research as the case study in PT. Total E&P Indonesie in offshore area by collecting the data of well intervention activities that have been done on 736 wells. Through the set of analysis and Focus Group Discussion (FGD) with experts resulted 12 dominant factors influenced the well intervention productivity in offshore area and well intervention productivity index 70.8 Scfd/USD wellhead in 2016 and 43.9 Scfd/USD wellhead in 2017. And still by Focus Group Discussion (FGD), there are 18 obstacles of the dominant factor and 31 root causes have been identified which is then analized and resulted 9 recommendations of well intervention productivity improvement.

Abstract

Maintaining consistent quality of crude palm oil (CPO) remains a significant challenge in palm oil mills, particularly due to fluctuations in Free Fatty Acid (FFA) levels that influence product value and processing efficiency. This study evaluates process capability and proposes quality improvement strategies at PT Perkebunan Nusantara IV PKS Bah Jambi using the Six Sigma DMAIC framework. Production quality data were analyzed through control charts, regression analysis, fishbone diagrams, and Failure Mode and Effect Analysis (FMEA). Initial measurement revealed that the average FFA level exceeded premium standards with a sigma level below two, indicating limited process capability. The findings highlight Fresh Fruit Bunch resting time and overripe fruit as a critical factor affecting quality deviation. Improvement strategies emphasize reducing waiting time and stabilizing sterilization parameters. The study demonstrates that a structured Six Sigma approach can effectively minimize process variability while enhancing operational performance in palm oil processing industries.
