Singapore-listed Mirach Energy reported that Kampung Minyak oil field (KM) in south Sumatra, Indonesia, saw new results from the KM team’s work-over of the existing well at KM-174, following the employment of a different work program. Within 5 days, the well started producing 28 barrels of oil per day, and is currently producing at a stabilized rate of 16 barrels per day with 30 percent water cut rate.
The work program involved the testing of casing pressure, opening tubing and casing valves, pressure releasing and the installation of a new well head to apply inverse-well flushing method to clean out sand to a depth of 312 feet (95 meters), prior to the adding of production tubing, sucker rod and pumps at the 197 feet (60 meters) depth for
The KM oilfield currently has 290 existing oil wells, where 15 wells had been reopened for testing that saw only an average of 1.8 barrels of production per well per day. This production per well is largely a result of the heavy clogging of the well bores and oil layers due to the reservoir formation made up of large void channels that attracted sand accumulation.
Following the success of this work program, the Company intends to accelerate its work-over of existing wells using similar processes and techniques on the next batch of 5 wells.
