HEAVY OIL ROUTINE SERVICE CYCLE TIME IMPROVEMENT

摘要

In Heavy Oil operations, well routine service jobs are important to minimize production decline. With an average of 2000 to 2500 jobs completed in a year, any improvement in the current process will give good benefit to withstand high decline in production rate. Since 2008, the cycle time has steadily increased from 20 to over 30 hours per job. More time to deliver HES activities and utilizations of work-over rig units for routine service jobs, gradually lead to increasing of the routine service cycle time.rnLean Sigma has applied to improve the current process with only focused on routine service main job and work-over rig modification. The outputs of the project are no incidents and reduction of the routine service cycle time job. In order to go over the project, Pareto diagram was developed and showed two big areas of improvement, which were HES activities and tripping jobs.rnAfter some discussions, strategy was developed. Standardized HES form and SOP, with standardized job phases, was agreed as an important strategy for project goals. Other strategies were modifications of some parts of work-over rigs and decommissioned of some nonproductive equipment. Good communication and socialization to all parties has been conducted intensively by team projects.rnThe project strategy began implementation in May 2013. The result of the project is average hoist productivity increase of 8% and rig productivity increase up to 46%. The significant improvement was showed at HES activity phase, both in hoist and rig operations. Total Accrued Financial Benefit during running of this project is approximately $75 MM and there have been no incident records related to this project. Regular monthly meetings, refreshing SOP, close communication and monitoring have been conducted for control of the project. Leadership support and operation close monitoring were the key success to achieve the project goals.
