Bila ada rekan2 yang ingin tahu, berikut abstrak2 saya saat pertemuan AAPG di Athena (2007) dan Capetown (2008). salam, awang ---------------------------------------- AAPG Athena (2007) Tectonic and Depositional History of Salawati Basin, Papua - Indonesia : Implications to the Occurrences of Miocene Kais Carbonate Play Types awang harun satyana, Government of Indonesia’s Implementing Body for Upstream Oil and Gas Business (BPMIGAS), Jakarta, Indonesia Salawati Basin, Papua in Eastern Indonesia has been producing oil and gas from Miocene carbonate reservoirs for almost sixty years. First discovery occurred in 1936 from Klamono structure of Late Miocene Kais carbonate reefal build-up (later called as Kasim play type). Important discoveries occurred during 1970s when the basin was intensively explored. Many fields of carbonate build-ups were discovered, including the Kasim and Walio fields which ever became the biggest oil producers in Southeast Asia for build-up play. Significant discoveries occurred again during 1990s when discoveries of Matoa, Southwest “O”, and “Matoa-20” took place. Their plays are different : faulted Kais platform carbonates (Matoa play type), subtle very low-relief Kais build-up (Southwest “O” play type) and subtle intra-Kais platform build-up (Matoa-20 play type). Recent exploration activities in the Salawati Basin still targeting all of these plays. Salawati Basin underwent tectonic reversal during the Miocene-Pliocene as a response to the advent of the Sorong Fault megashear. During this period, the tilting of the basin rotated clockwisely from tilting southward, through southwestward, and eventually northward. The Kais platform development and carbonate sedimentation were strongly controlled by this basin's polarity change. Most of the Matoa-20 and Southwest “O” play types developed in the lagoonal facies when the basin tilted southward. Growth of the classical Kasim play type occurred when substrates of the reefal build-ups subsided slightly due to the change of basin's polarity southwestward. As the basin rapidly tilted northward, compensating faults were formed and resulted in faulted platform of Matoa play type. AAPG Capetown (2008) awang harun satyana, Government of Indonesia’s Implementing Body for Upstream Oil and Gas Business (BPMIGAS), Jakarta, Indonesia Aromatic Methylphenanthrene Biomarker and Maturity of Oils Keys to Identifying New Active Source Rocks in the Salawati Basin, Indonesia Salawati Basin, Indonesia is an asymmetric foreland basin with a foredeep kitchen bordered by deformed zone of the Sorong Fault. Early-migrated and moderate to heavy oils distribute in the updip area, whereas late-migrated and light oils and gas distribute in downdip area approaching the kitchen. The hydrocarbon sources have been Miocene Kais and Klasafet mudstones and shales. The sources are increasingly deeply buried from updip to downdip area, causing oils increasingly mature from updip to downdip area. The maturity of oils from updip to downdip area is shown by vitrinite reflectance equivalent (VRE) of oil derived from formulation of intensity of aromatic biomarker of methylphenanthrene (MP) (m/z 192). The MP index (MPI) and VRE of oils are increasingly higher towards the downdip area showing that oils are increasingly mature (existing MPI data range from 1.1 to 1.6 or VRE from 0.9 to 1.4 %). However, at the Sorong deformed zone, there are oil seeps which do not follow the characteristic pattern. They show MPI of 0.52 or VRE of 0.7 %. This is peculiar since these seeps, if they were sourced by Kais/Klasafet, should have the highest maturity in the basin because the source rocks in this area are maximum buried and they have entered overmature window as proved by the occurrence of high CO2 gas nearby due to thermal degradation of Kais carbonate. The presence of low maturity oil seeps in the Salawati foredeep kitchen shows that the oils should had been sourced by younger rocks than Kais/Klasafet rocks and should be in the upper oil window. The expected source is early Pliocene Lower Klasaman shales which have significant terrestrial input than those of Kais/Klasafet. The terrestrial input of Klasaman sources is proved by biomarker and isotopes. Therefore, based on oil geochemistry, we have identified Lower Klasaman shales as additional source in the petroleum system of the Salawati Basin. Sedimentologic and structural evaluation of the Klasaman sources will determine the generation capacity of this formation. Preliminary volumetric calculation shows that total 2000 MMBO and/or 3000 BCFG from Lower Klasaman sources could be trapped. ----------------- --- On Fri, 3/13/09, herman.dar...@shell.com <herman.dar...@shell.com> wrote: From: herman.dar...@shell.com <herman.dar...@shell.com> Subject: RE: [iagi-net-l] Re: [Geo_unpad] Jan Reerink (1871) dan Tantangan Eksplorasi Jawa To: iagi-net@iagi.or.id Date: Friday, March 13, 2009, 5:33 PM Wah beruntung orang-orang Mesir, Yunani dll. bisa dengar presentasi orang-orang top Indonesia dan lihat poster-poster mengenai Indonesia.
