PT PERTAMINA PERSERO DAN ENTITAS ANAKAND SUBSIDIARIES Lampiran 61 Schedule INFORMASI TAMBAHAN 31 DESEMBER 2012 DAN 2011 TIDAK DIAUDIT SUPPLEMENTAL INFORMATION 31 DECEMBER 2012 AND 2011 UNAUDITED ESTIMASI CADANGAN MINYAK DAN GAS BUMI TIDAK DIAUDIT ESTIMATED CRUDE OIL AND NATURAL GAS RESERVES UNAUDITED Perusahaan, PT Pertamina EP “PEP”, Entitas Anak PT Pertamina Hulu Energi “PHE” dan PT Pertamina EP Cepu “PEPC” tidak mempunyai hak kepemilikan atas cadangan minyak dan gas, tetapi mempunyai hak untuk menerima hasil produksi danatau pendapatan dari penjualan minyak dan gas sesuai dengan KKS dan kontrak kerjasama lainnya. The Company, PT Pertamina EP “PEP”, Subsidiaries of PT Pertamina Hulu Energi “PHE” and PT Pertamina EP Cepu “PEPC” have no ownership interests in the oil and gas reserves, but rather have the right to receive production andor revenues from the sales of oil and gas in accordance with their PSCs and other production sharing arrangements. Jumlah cadangan terbukti proved reserves hanya merupakan taksiran, dan tidak dimaksudkan untuk menggambarkan nilai yang dapat direalisasikan atau nilai wajar dari cadangan Perusahaan, PEP, Entitas Anak PHE dan PEPC. Taksiran ini dapat berubah bila tersedia informasi baru di kemudian hari. Terdapat berbagai ketidakpastian inheren dalam mengestimasi cadangan minyak mentah dan gas, termasuk faktor- faktor yang berada di luar kendali Perusahaan, PEP, Entitas Anak PHE dan PEPC. The quantity of proved reserves is only an estimation, and is not intended to illustrate the realisable value or fair value of the Company’s, PEP’s, PHE Subsidiaries’ and PEPC’s reserves. This estimation is subject to changes whenever new information is available in the future. There are many inherent uncertainties in estimating crude oil and gas reserves, including factors beyond the Company’s, PEP’s, PHE Subsidiaries’ and PEPC’s control. Manajemen berkeyakinan bahwa kuantitas cadangan termasuk bagian Pemerintah merupakan taksiran yang wajar berdasarkan data geologi dan teknik yang tersedia saat ini. Management is of the opinion that the reserve quantities, which include Government’s shares are reasonable based on available geological and technical data. Sebelum tahun 2012, perhitungan cadangan terbukti minyak dan gas bumi PEP dan PHE berdasarkan pada pedoman Society Petroleum Engineer 2001 “SPE 2001” sedangkan PEPC berdasarkan pada Society Petroleum Engineer – Petroleum Resources Management System 2007 “PRMS 2007” sesuai tabel I di bawah ini: Before the year 2012, the calculation of proved oil and gas reserves, which are based on Society Petroleum Engineer 2001 “SPE 2001” guidelines for PEP as well as PHE and based on Society Petroleum Engineer – Petroleum Resources Management System 2007 “PRMS 2007” for PEPC, are detailed in the following table I: TABEL ITABLE I Cadangan minyak dan gas bumi Per 31 Desember 2012 Crude oil and natural gas reserves 31 December 2012 Entitas AnakSubsidiaries Saldo 1 Januari 2011Balance 1 January 2011 Penyesuaian Adjustments Produksi Production Saldo akhir 31 Desember 2011Ending balance 31 December 2011 Penyesuaian Adjustments Produksi Production Saldo akhir 31 Desember 2012Ending balance 31 December 2012 PT Pertamina Persero I Blok VietnamVietnam Block SPE 2001 - Minyak dan kondensatOil and condensate MBBLs - 2,070 - 2,070 244 - 2,314 - Gas bumiNatural gas MBOE - 601 - 601 72 - 673 Sub jumlah cadanganSub total reserve minyakoil - 2,070 - 2,070 244 - 2,314 Sub jumlah cadanganSub total reserve gas buminatural gas - 601 - 601 72 - 673 PT PERTAMINA PERSERO DAN ENTITAS ANAKAND SUBSIDIARIES Lampiran 62 Schedule INFORMASI TAMBAHAN 31 DESEMBER 2012 DAN 2011 TIDAK DIAUDIT SUPPLEMENTAL INFORMATION 31 DECEMBER 2012 AND 2011 UNAUDITED ESTIMASI CADANGAN MINYAK DAN GAS BUMI TIDAK DIAUDIT lanjutan ESTIMATED CRUDE OIL AND NATURAL GAS RESERVES UNAUDITED continued Entitas AnakSubsidiaries Saldo 1 Januari 2011Balance1 January 2011 Penyesuaian Adjustments Produksi Production Saldo akhir 31 Desember 2011Ending balance 31 December 2011 Penyesuaian Adjustments Produksi Production Saldo akhir 31 Desember 2012Ending balance 31 December 2012 PT Pertamina EP SPE 2001: I Sumatera - Minyak dan kondensatOil and condensate MBBLs 339,198 39,535 4,368 295,295 18,935 4,931 271,429 - Gas bumiNatural gas MBOE 654,937 1,195 27,631 626,111 19,187 26,608 580,316 II JawaJava - Minyak dan kondensatOil and condensate MBBLs 260,003 8 17,686 242,309 1,725 16,572 224,012 - Gas bumiNatural gas MBOE 207,483 11 26,796 180,698 13,979 26,478 168,199 III KTIEast Indonesia - Minyak dan kondensatOil and condensate MBBLs 139,848 82,652 2,909 54,287 8,568 3,788 59,067 - Gas bumiNatural gas MBOE 99,090 1 470 98,621 5,880 675 92,066 IV KBTTAC - Minyak dan kondensatOil and condensate MBBLs 134,645 1 6,363 128,283 68,714 6,132 190,865 - Gas bumiNatural gas MBOE 107,097 1 5,429 101,667 4,881 4,049 92,737 V KSOOC - Minyak dan kondensatOil and condensate MBBLs 71,847 792 1,233 71,406 812 1,506 69,088 - Gas bumiNatural gas MBOE 3,591 - - 3,591 2,476 - 6,067 VI ProyekProject - Minyak dan kondensatOil and condensate MBBLs 14,000 - 898 13,102 91,219 1,060 103,261 - Gas bumiNatural gas MBOE 361,474 47,501 4,809 404,166 131,353 6,197 266,616 VII Unit Bisnis Eksplorasi dan Eksploitasi Business Unit Exploration and Exploitation UBEP - Minyak dan kondensatOil and condensate MBBLs 245,374 18,386 12,168 214,820 14,478 12,725 187,617 - Gas bumiNatural gas MBOE 46,829 881 2,292 43,656 9,707 2,565 50,798 Sub jumlah cadanganSub total reserve minyakoil 1,204,915 139,788 45,625 1,019,502 132,551 46,714 1,105,339 Sub jumlah cadanganSub total reserve gas buminatural gas 1,480,501 45,436 67,427 1,458,510 135,139 66,572 1,256,799
