The Center for Oil and Gas Research and Technology (Lemigas) still needs more time to ensure the majeure or majeure conditions of Kepodang Filed, Blok Muriah. Andy Setyo, of Lemigas Exploitation Research and Technology Development Program Group, said it still needs to review again the basin or subsurface of Kepodang Field.
The reason, Lemigas takes up to three months to complete the study subsurface Kepodang Field. This means, the certainty of the fate of the new Kepodang Field can be determined at the beginning of 2018.
"Hopefully early next year there are already results," said Andy, Monday (20/11).
That way, Lemigas at this time still can not confirm the condition of pitch in the gas field. Moreover, later study results Lemigas still discussed first with Petronas, the field operator.
Previously, Head of Program and Communications Division Division of Special Unit for Upstream Oil and Gas (SKK Migas) Business Activities, Wisnu Prabawa Taher, said that there are already calculations of Lemigas analysis showing that in Kepodang Field Inside reserves only 107 billions of standard cubic feet of gas (bscf ).
The amount of such reserves is entirely not necessarily produced. Whereas in the plan of development (POD) Kepodang Field approved by the government includes the amount of hydrocarbons in this field that can be produced into gas reaches 354 bscf.
"In summary, based on the material analysis of the balance by Lemigas, we found inplace Kepodang 107 bscf versus inhouse-rate analysis of Petronas of 94 bscf," explained Vishnu
Although the results of Lemigas analysis indicate a decrease in reserves in Kepodang Field, Wisnu said that the government through SKK Migas has not been able to provide a force majure status. Because, until now the process of analysis in SKK Migas still not completed.
"Related kahar, still discussed again for the commercial aspect, so formally can not be called force majure," said Vishnu.
Based on data from SKK Migas, Kepodang Blok Muriah project is operated by Petronas Carigali Muriah Ltd since 1 January 2004. Kepodang Field is located in offshore area of East Java, about 180 kilometers north-east of Semarang City. This is the first field to be developed in the Muriah Block.
Kepodang Blok Muriah by Petronas
The original POD of Kepokang Block Muriah Field was approved in 2005 and then revised in 2012. From hydrocarbon reserves in Kepodang Field, it is expected to produce about 354 bscf of gas. Meanwhile, Kepodang Field gas production is estimated to reach 116 million standard cubic feet per day (mmscfd). However, gas field production is currently only about 70 mmscfd-80 mmscfd.
The development scenario of Muriah Block at that time was producing integrated gas from upstream to downstream. For development of integrated gas production facility, cover upstream scheme. That is, the construction of a central processing platform (CPP), consisting of eight well slots, WHT-C (Wellhead Tower-C) consists of five well slots, a 10.7 km infield flowline of WHT-C to CPP and on-shore remote control.
The downstream scheme operated by PT Bakrie and Brothers Tbk (BNBR) and PT Perusahaan Gas Negara Tbk (PGN) consists of 200 km export pipeline construction and onshore receiving facility (ORF) at Tambak Lorok Power Plant, Semarang.
Kepodang Field Project was constrained due to downstream problems, namely the construction of gas pipelines. Petronas and its new partners can produce gas from Kepodang Field in the third quarter of 2015.

Lemigas Kaji Ulang Kahar Kepodang
Pusat Penelitian dan Teknologi Minyak dan Gas Bumi (Lemigas) masih membutuhkan waktu lebih lama lagi memastikan kondisi kahar atau force majeure Lapangan Kepodang, Blok Muriah. Andy Setyo, dari Kelompok Program Penelitian dan Pengembangan Teknologi Eksploitasi Lemigas, mengatakan, pihaknya masih perlu mengkaji ulang lagi cekungan atau subsurface Lapangan Kepodang.
Pasalnya, Lemigas membutuhkan waktu hingga tiga bulan untuk menyelesaikan kajian subsurface Lapangan Kepodang. Ini berarti, kepastian nasib Lapangan Kepodang baru bisa ditentukan pada awal tahun 2018.
"Mudah-mudahan awal tahun depan sudah ada hasil,” kata Andy, Senin (20/11).
Dengan begitu, Lemigas saat ini masih belum bisa memastikan kondisi kahar di lapangan gas tersebut. Apalagi nantinya hasil kajian Lemigas masih didiskusikan terlebih dahulu dengan Petronas, operator lapangan tersebut.
Sebelumnya, Kepala Divisi Program dan Komunikasi Satuan Kerja Khusus Pelaksana Kegiatan Usaha Hulu Minyak dan Gas Bumi (SKK Migas) Wisnu Prabawa Taher mengatakan, sudah ada hasil perhitungan analisa Lemigas yang menunjukan cadangan inplace Lapangan Kepodang hanya 107 billions of standard cubic feet of gas (bscf).
Jumlah cadangan tersebut itu sepenuhnya belum tentu diproduksi. Padahal dalam plan of development (POD) Lapangan Kepodang yang disetujui oleh pemerintah mencantumkan jumlah hidrokarbon di lapangan ini yang bisa diproduksikan menjadi gas mencapai 354 bscf.
"Secara ringkas, berdasarkan analisis material balance oleh Lemigas, didapatkan inplace Kepodang 107 bscf versus angka inhouse analysis Petronas sebesar 94 bscf," jelas Wisnu
Biarpun hasil analisa Lemigas menunjukan adanya penurunan jumlah cadangan di Lapangan Kepodang, Wisnu menyebut pemerintah melalui SKK Migas belum bisa memberikan status force majure atau kahar. Pasalnya, hingga saat ini proses analisa di SKK Migas masih belum selesai.
"Terkait kahar, masih dibahas kembali untuk aspek komersialnya, sehingga secara formal belum bisa disebut force majure," jelas Wisnu.
Berdasarkan data SKK Migas, proyek Kepodang Blok Muriah dioperasikan oleh Petronas Carigali Muriah Ltd sejak 1 Januari 2004. Lapangan Kepodang ini berlokasi di kawasan lepas pantai Jawa Timur, sekitar 180 kilometer sebelah timur laut Kota Semarang. Ini merupakan lapangan pertama yang akan dikembangkan di Blok Muriah.
POD original Lapangan Kepodang Blok Muriah disetujui tahun 2005 dan kemudian direvisi tahun 2012. Dari cadangan hidrokarbon di Lapangan Kepodang, diharapkan dapat diproduksikan gas sekitar 354 bscf. Sedangkan produksi gas Lapangan Kepodang diperkirakan dapat mencapai 116 juta kaki kubik per hari alias million standard cubic feet per day (mmscfd). Namun saat ini produksi lapangan gas tersebut hanya berkisar 70 mmscfd-80 mmscfd.
Skenario pengembangan Blok Muriah kala itu adalah memproduksi gas terintegrasi dari hulu hingga hilir. Untuk pengembangan fasilitas produksi gas terintegrasi, mencakup skema hulu. Yakni pembangunan central processing platform (CPP), terdiri dari delapan slot sumur, WHT-C (Wellhead Tower-C) terdiri dari lima slot sumur, infield flowline 10" sepanjang 2,7 km dari WHT-C ke CPP, serta on-shore remote control.
Skema hilir yang dioperasikan PT Bakrie and Brothers Tbk (BNBR) serta PT Perusahaan Gas Negara Tbk (PGN) terdiri dari pembangunan export pipeline sepanjang 200 km serta onshore receiving facility (ORF) di Tambak Lorok Power Plant, Semarang.
Proyek Lapangan Kepodang ini sempat terkendala karena masalah hilir, yaitu pembangunan pipa gas. Petronas dan mitranya baru bisa memproduksi gas dari Lapangan Kepodang di kuartal III- 2015.
