Peciko

Peciko Gas Field Profile

The Peciko gas field is located offshore in the Mahakam Block, specifically in the Mahakam River delta area, East Kalimantan, Indonesia. It is situated 60 km northeast of the city of Balikpapan and southwest of the Bekapai field in the Makassar Straits.
The field features both structural and stratigraphic gas traps, with the main reservoir sequence occurring at a depth of 2,100-3,000 meters (or up to 3,900 meters in some areas). The reservoir consists of fine to medium-grained sands scattered throughout deposits of shale and siltstone.

The Peciko gas field was discovered in 1991, although it was not fully delineated until the following decade.
The development of Peciko was launched in 1996 to boost Total Indonesia's gas production capacity to meet new LNG contracts. Phase 1 of the project came onstream in December 1999.

The Peciko gas field is operated by Total Indonesia, with Total and Japan's Inpex Ltd. holding a 50-50 partnership in the Mahakam production sharing contract (PSC) area.

The initial development involved two offshore unmanned 12-slot manifold wellhead platforms (MWP A and B). Gas and condensate are transported via pipelines to the onshore Senipah Peciko Process Area (PPA), where they undergo processing. The processed gas is then sent through an 86-km, 42-inch pipeline to the Bontang LNG plant.
Phase 1 of the project was designed to produce up to 800 MMcfd of gas and 16,000 b/d of condensate. Further development stages included the installation of additional platforms and wells, aiming to increase production to 1 bcfd by the end of 2001 and eventually to 1.25 bcfd by 2005.
The field's wells have high productivity, averaging 50-60 MMcf/d (or up to 80 MMcfd in some reports).

The estimated recoverable reserves of the Peciko gas field are approximately 6.2 trillion cubic feet (tcf) of gas, along with associated condensate.
The production from the Peciko field significantly contributes to the Bontang LNG plant, which is owned by various stakeholders including Total Indonesia, Pertamina, Virginia Indonesia Co., and Unocal Corp. The bulk of the supply is intended for LNG contracts with Japan, South Korea, and Taiwan.

Local fabricator PT Gunu Nasa built all the Peciko platforms at its yard in West Java. Canadian drilling contractor PT Santa Fe was involved in drilling the wells. Other contractors include Punj Lloyd, PT Nippon Steel Construction Indonesia, and Saipem for various phases of the project.

As of recent updates, Pertamina Hulu Mahakam (PHM) is advancing with new development projects in the Mahakam Block, including the OPLL-3B Offshore project. This project involves drilling and connecting new wells in the Peciko, South Mahakam, and Sisi Nubi fields to optimize production and enhance gas reserves. The project is expected to increase gas reserves by approximately 75 Bcf and condensate by 1 MMbbl, with peak production anticipated in 2026.

The Peciko project is part of the larger Mahakam PSC area, which has been a significant source of hydrocarbons for Indonesia since the start-up of the Bekapai gas field in 1974. The Mahakam area has produced about 1 billion barrels of oil and condensate and over 4 trillion cubic feet of natural gas.
