JAKARTA. PT Pertamina EP is able in increasing success ratio of exploration drilling along the period of January-August 2010 to 84, 6 %. From 12 wells which had been drilled until August 2010 and one re-entry well, 11 wells were claimed to be successful while 2 wells were not.

Success ratio of exploration drilling in the period of January – August 2010 is higher than the same period in 2 years before. From 8 wildcat wells, 7 of them were successful and produced oil and gas. It is as stated by Exploration and Development Director, Syamsu Alam, Sunday (8/22).

The increasing ratio of this exploration drilling is a result of business process improvement to decrease risk and improve success chance of exploration. This effort was done by involving technology support and EP Technology Center, and also optimizing the drilling operation supervision to identify exactly and fast about the indication of oil and natural gas existence.

In 2008, success ratio of exploration drilling in the period of January-August reached 76 % or from 8 wells which had been drilled up to August 2008, 6 wells were successful and 2 wells were not. Next, in 2009, success ratio of exploration drilling in the period of January-August reached 76, 9 % or from 12 wells which had been drilled up to August 2009 and 1 re-entry well, 10 wells were successful and 3 wells were not.

In the period of January to August 2010, Pertamina EP held 12 exploration drillings and one re-entry well. Exploration drilling consisted of 8 wildcat wells which cover 5 wells in West Java (Akasia Bagus 1, Karangluhur 1, Karangdegan 1, Jati Keling 1, and Pondok Mekar 1), 1 well in Jambi (Kalalili 1), and 2 wells in South Sumatera (Manduru 1 and Ginaya 1). From 8 wildcat wells, 7 of them were successful in finding oil and gas, and 1 well was not. However, one re-entry well in Arjawinangun in West Java was not successful.

Next, Pertamina EP also held three drillings of delineation Pondok Makmur in Bekasi (PDM-3, PDM-4, PDM-5) and one drilling in Pagardewa, South Sumatera (PDW-6X). Four of those delineation drillings found oil and gas. Pondok Makmur well will be developed soon in the second phase of Plan of Development (POD) and it is predicted to be produced by the end of 2011.

In the first semester of 2010, said Syamsu Alam, Pertamina EP has found new oil and gas reservation for about 61 million barrel and gas for about 619 billions cubic feet in the first semester of 2010. The finding of this first semester is higher than predicted amount of oil and gas production which will be produced in 2010 for about 46, 7 barrel and 381 billion cubic feet. (AK)
