Increasing Crude Oil Production by Intermit Operation in Mae Soon Oil Field Fang Basin, Thailand

Saowaluck Pitukwong, Akkhapun Wannakomol


This study conducted an experiment to increase crude oil production by applying 8 days intermit operation to FA-MS-07-08 well, located in Mae soon oil field, Fang basin. The principle of intermit operation [1] is to reduce the operating hours of the sucker rod pumping unit from 24 hours per day to 12 hours per day which is resulted in having enough time for production fluids (crude oil and water) segregation and also for oil recovering from the deeper part of the reservoir. The study methodology included (1) required data collecting, e.g. production history data, drilling data and reservoir data [11] of Mae Soon oil field, the well bore data when start and stop the sucker rod pump, (2) production fluid samples collected from tested well analyzing and testing in laboratory, and (3) economic returns evaluating. After applying intermit operation to the tested well, it had been found that the intermit operation could reduce the electricity power cost of sucker rod pumping unit about 5,680 Baht per month. This operation could increase oil production rate about 73 percent compared to the normal operation, and could also give incomes from selling crude oil about 552,320 Baht per month.
