Area: 10.4 km2
Reserves: 500mmbbls
Production: 60 mmbbls
Perlak is an established oilfield, located in a mature hydrocarbon province of Aceh, Northeast Sumatran basin and covers an area of 10.4 km2. The field is one of the oldest producing fields in the world, first discovered in 1899 and lies on-trend with many producing hydrocarbon fields. The Perlak field was produced primarily in the period up to the early 1940s from the crestal part of the structure. Over 300 wells have been drilled to date, with 250 of those put into production. The field has produced approximately 60 mmbbls from shallow depths of less than 1,000 metres. The oil is very light with average API of 45-50 degrees. The average recovery factor of the developed area to date is estimated at 36%. The field was shut-in during World War II and there has been limited activity carried out since that time, mainly by smaller local operators. Eleven wells had been drilled on the field since 1970s. Two of the more recent wells drilled in 2011 were put into production of 180 and 100 bopd, respectively, producing high quality oil 53 degrees API. The field has a licence period of 15 years through to 2032. It is estimated that the field has material remaining oil in place of up to 500mmbbls.
