The Matindok gas development project comprises the development of the Donggi, Matindok, Maleoraja, Sukamaju and Minahaki fields, which are located in the Banggai basin in Central Sulawesi, Indonesia. First production from the project is expected in early 2016.
The Donggi and Minahaki fields are located in the Toili Barat district whereas the Sukamaju, Maleoraja and Matindok fields are located in Batui district.
PT Pertamina EP is implementing the project. The initial plan of development (POD) for the project was approved in December 2008 and the existing revised POD was approved in March 2011. As of July 2014, 21% of the construction activities for the project had been completed.
Reserves and production
The fields are together estimated to hold 852.75 billion cubic feet (bcf) of gas. Net production from the project is estimated to be 105 million standard cubic feet a day (Mmscfd) and the production life of the project is predicted to be 20 years.
Matindok gas project details
The project will overall involve the drilling of 18 development wells and six work-over wells. Four work-over and four development wells will be drilled at Donggi, while seven development wells will be drilled at Matindok.
Four development wells will also be drilled at Minahaki, two development wells and a work over well at Maleoraja, and a development well and a work over well at Sukamaju.
The project also involves the construction of two central processing plants (CPPs), with a capacity of 50MMscfd and 55MMscfd respectively, at Donggi and Matindok. The construction of the Donggi CPP started in December 2013.
Other project activities will include the construction of block stations at Donggi, Sukamaju and Matindok, manifolding stations at Maleoraja and Minahaki, export pipelines connecting the Donggi-Senoro LNG plant, and development of new roads and improvement of existing roads to facilitate drilling activities.
The gas fuel required for the project facilities will be sourced from the project site itself, while the required oil fuel will be supplied from one of Pertamina's refinery.
Gas supply from Matindok gas project
From the overall production, 85MMscfd of gas will be supplied to the Donggi-Senoro LNG plant, which is being constructed by the Donggi-Senoro LNG joint venture comprising Sulawesi LNG Development (Mitsubishi and Korea Gas Corporation - 59.9%), Pertamina (29%) and Medco (11.1%), whereas 20MMscfd will be supplied to PT PLN (Persero).
The $2.8bn Donggi-Senoro LNG liquefaction plant will have a nameplate capacity of two million tonnes a year, comprising a single LNG processing train using Air Products' multi-component refrigerant LNG process technology.
Contractors involved with the Indonesian gas project
The Japan Bank for International Cooperation (JBIC) conducted environmental impact assessment (EIA) for the project.
The $234m engineering, procurement, construction and installation (EPCI) contract for the gas well pads, flowlines, pipelines, the central processing plant at Matindok with gas treatment facilities such as acid gas removal and sulphur removal, and ancillary infrastructure was awarded to the joint venture of Technip and Wijaya Karya (WIKA).
In June 2015, Integraph and its local distributor and partner PT Everest Technology were contracted to provide the former's proprietary SmartPlant Foundation and SmartPlant Enterprise for Owner Operators (SPO) Core solutions, to power a new electronic document management system (EDMS) for the project.
Gas treatment technologies will be provided by Shell, while forged fittings and branch outlets for the project are being supplied by Delcorte Fittings.
