WEST MADURA OFFSHORE
Located to the southwest of the island of Madura, Pertamina Hulu Energi West Madura Offshore (WMO) operates 10 platform on 98 wells.
Commencing in 1982, production has averaged 250 BOPD, with the highest production level reaching 11,000 BOPD of crude oil, up to October 2006 cummulative production has reached 6,010,000 barrel oil and 13,300 MMSCF of gas.
Discovered in 1983, it now produces an average of 42 BOPD of condensate and 7 MMSCFD of natural gas. All gas gas and condensate production is pumped through a 65-kilometer, 14-inch long subsea pipeline to the Receiving Station (ORF) in Gresik. Total production as of the end of 2010 reached 1,395,000 barrels of condensate and 89,500 MMSCF of gas.
KE-6 field consists of one gas well and started its initial production in January 2000 with 437 BCPD condensate) and 14.4 MMSCFD of natural gas. Cumulatively, total production of the blok reached 220 kbbl and 9.7 BCF.
The discovery of the KE-30 field was preceded by the drilling of well KE 30-1 in August 2001. The development of the KE-30 field was carried out by drilling two exploration wells, namely KE 30-1 and KE 30-2. POD in the field was completed in August 2012, with a total of 9 development wells being successfully drilled. KE-30 reached peak production in mid 2008 at a rate of 4,500 BOPD,while gas production reached a peak of 7.5 MMSCFD in July 2013. At the present time, this field has 12 development wells.
Commenced in November 2001, produces an average of 10,000 BOPD of oil and 18 MMSCFD of natural gas from 4 wells. However, production declined after the 8th year. Total production amounts to 16,160,000 barrels of oil and 53,500 MMSCF of natural gas.
This field began to be developed in 2003, and production commenced in March 2005 through the KE-40A-1 well. Peak crude oil production amounted to 9,500 BOPD and gas production to 38 MMSCFD in March 2007. Currently, the average daily production of crude oil and gas from KE-40 is 1,500 BOPD and 13 MMSCFD, respectively.
GAS EXPANSION PHASE II
In 2007, Kodeco developed a new compressor at the AW platform. It also constructed a 16-inch pipeline to carry 200 BBTU and 175 MMSCFD of natural gas from PPP to ORF.
This field commenced development in 2008, and production started in December 2008 through the KE-32A-3 well. Peak gas production amounted to 73,431 MMSCFD in November 2009.
The KE-38A field was developed in 2008, and commenced production in December 2008 through the KE-38A-6 well. Peak crude oil and gas production amounted to 19,258 BOPD and 94,431 MMSCFD, respectively, in August 2010.
PHE-38B commenced development in 2013 with 8 developmentwells, and started production in March 2013 through the PHE-38B-1 PHE and PHE-38B-2 wells. Crude oil and gas production reached a peak of 15,587 BOPD and 35 MMSCFD gas, respectively, in August 2013.
The PHE-54 field has six development wells and commenced production in July 2013 through the PHE-54A-7 well. Peak crude oil production reached 2,794 BOPD in September 2013, while peak gas production reached 31.5 MMSCFD in November 2013.
This field commenced development in 2013, and started production in December 2013 through the PHE-39-A5 well. Peak crude oil production reached 2,942 BOPD in April 2014, while peak gas production reached 25.58 MMSCFD in August 2014. The field has seven development wells.
FSO (Floating Storage and Offloading) platform operates in the offshore of PHE WMO has a capacity of 600,000 barrels and accommodation facilities for 150 workers. FSO Abherka is the first project of Pertamina Perkapalan as part of the shift from tankers to an FSOs. Pertamina Perkapalan will operate the FSO for 10 years in the PHE WMO area of operations.
ONSHORE RECEIVING FACILITY (ORF)
The gas produced by the offshore platforms is transported to a gas processing facility (ORF) some 70 km away towards Gresik through two pipelines, one 14 inches in diameter and the other 16 inches. The gas is then dried before being delivered to the customers, namely, PT. PGN (Persero) Tbk, PT. PLN (Persero) and PT. Gresik Migas. The processing of the gas also produces condensate, which is collected in two tanks, each with a capacity of 10,000 barrels.
LAMONGAN SHOREBASE (LSB)
Lamongan Shorebase is a supporting facility to receive, store, and distribute all goods for operation, drilling and project. The facilities at the Lamongan Shorebase, which have been certified with ISO 14001, OHSAS 18001, and ISO 9001:2008, comprises of open yard, covered warehouse, bulk tank, cargo handling, crew change, and jetty to serve the entire PHE WMO vessels.
NEW PLAN OF DEVELOPMENT (POD)
The integrated POD I covers PHE-7, PHE-12, PHE-24, PHE-29, PHE-44 and PHE-48. Integrated POD I was approved on October 23, 2013, covering a total of 18 development wells. Its oil production contribution is estimated at 12,650 BOPD and its gas contribution at 27.4 MMSCFD. The production plan can be implemented in 2016.
