Subang field?s oil, gas production on target

PT Pertamina EP (PEP), a subsidiary of state owned oil and gas firm PT Pertamina, said production from its Subang field in Karawang and Subang regencies in West Java province came in line with target in the first semester of the year.

As of end-June, oil production stood at 1,196 barrels per day (bpd), 102.6 percent of the target set in the firm?s 2016 Work Program & Budget (WP&B), while gas production reached 239.68 million cubic feet per day (mmscfd) or 100.87 percent to the WP&B target.

The field consists of 58 production wells and seven injection wells scattered in Cilamaya area of Karawang regency and some areas in Subang regency, Armand M Hukom, Subang Field Manager, said in a statement on Monday.

Armand said all oil from the field is supplied to the Balongan refinery, while the gas is supplied to consumers such as state-owned steel maker PT Krakatau Steel Tbk and state owned fertilizer firm PT Pupuk Kujang.

The firm also sells carbon dioxide (CO2) from the field to two main buyers, PT Samator and PT Aneka Gas Industri, Armand said.

PEP?s spokesperson Muhammad Baron said PEP?s Subang field has two CO2 removal plants located in Cilamaya and Subang respectively. The Cilamaya CO2 removal plant has been operating since 2000 and is designed with the capacity of reducing CO2 content in Subang?s gas from 40 percent to 5 percent. ?The CO2 gas is delivered to PT Samator at a volume of 1.172 mmscfd, generating US$1,842.95 per day,? Baron said.

Meanwhile, the Subang CO2 removal plant has been operating since October 2003, designed with the capacity of reducing CO2 element from 23 percent to 5 percent. ?The CO2 gas is delivered to PT Aneka Gas Industri at a volume of 1.820 mmscfd,? he said.

Armand said the Subang field is a pioneer in Indonesia in utilizing CO2. Thus far, there isn?t any other oil company which sells CO2 and makes money from it. Demand for CO2 has been increasing, he said, adding some other companies have asked for CO2 supplies from the field.

Armand said PEP built CO2 plants at Subang field because gas from the field has an average of 23 percent CO2 content, even 40 percent in some areas, while the existing regulation stipulates that gas is only allowed to be produced if the CO2 content is below 10 percent.
