การปรับปรุงประสิทธิภาพการขุดเจาะหลุมผลิตปิโตรเลียมบนแท่นขุดเจาะแบบเทนเดอร์

Abstract

This research aims to reduce wasted time in the drilling process of petroleum production wells compared to drilling hours of drilling before improvement, begins with studying and exploring research related to drilling petroleum production wells. Including the composition of the mud water to be used as information for conducting research. Then study the process of drilling production wells of the company case study and collect data on drilling hours in March – May 2021 to analyze the problems. And identifying the problem conditions that resulted in waiting time, it was found that the average waiting hours was 4.64 hours/well which is representing 5.45%. Which was main caused by the waiting process of the Mud circulation system. Therefore, the problem data was used to analyze the cause by Fishbone diagrams. The main cause of the problem is 1) the cause of the method due to the method of the Mud circulation system through the same set of pipes and 2) caused by materials/equipment from the examination of materials/equipment used in the same set. Therefore, the mixture of 2 types of mud water. The researcher has improved by using the Risk management principle based on the level of significant risk to improve activity for elimination by designing a schematic of a new Mud circulation system, installing additional equipment kits, preparing Work Instruction document, preparing checklist and training to educate operators. Then followed up on improvements by collecting data on drilling hours of February – April 2022, it was found that there was no longer waiting time in the drilling process.
