Abstract

Construction of oil and gas product storage facilities is one of the oil and gas activities in the downstream sector. A common impact on the environment from oil and gas activities is in the form of pollution of land, water, or air, it is necessary to identify the level of vulnerability to pollution early, areas that are sensitive to pollution are the main concern. The results of the initial identification of the level of vulnerability to pollution are shown in the map of the level of vulnerability to pollution processed using a geographic information system using the method of interpolation, weighting, and overlapping. The results of the initial identification of the level of vulnerability to pollution at the location of the oil and gas product storage facilities are divided into 3 (three) classes of vulnerability levels, low, medium, and high. The study area is in a relatively medium to high level of vulnerability with a high level of vulnerability being near the sea, so it needs high attention in its management.

Abstract

Tujuan dari penelitian ini adalah mengkaji karakteristik khusus topografi pada citra satelit yang dapatmencerminkan daerah potensi penghasil minyak dan gas bumi. Pendekatan yang digunakan adalah anomalitopografi . Dengan menggunakan citra penginderaan jauh, yaitu Citra Satelit Landsat TM yang direkampada Bulan Juni Tahun 1976. Pada citra penginderaan jauh karakter khusus topografi dapat diamati baikdari bentuk tinggian atau antiklinal, pola aliran sungai, serta kemiringan dan bayangan yang tampak padadata citra. Lokasi penelitian di Indramayu pada Cekungan Jawa Barat Utara yang merupakan daerah yangsudah terbukti (proven) adanya migas. Penentuan daerah potensi migas didasarkan pada asumsi 3 (tiga)parameter utama yaitu struktur, reservoir, dan migrasi. Parameter struktur didasarkan pada hasil identifi kasidan intepretasi citra satelit yang menghasilkan Remote sensing Potential Area (RPA). Parameter reservoirterdiri atas keberadaan sumur dan lapangan migas. Parameter migrasi didasarkan pada adanya sesar dankitchen area. Pembobotan dilakukan untuk menentukan kelas RPA, yaitu sangat potensial, potensial dankurang potensial. Hasil interpretasi diperoleh 84 RPA. Hasil validasi menggunakan data bawah permukaanmembuktikan bahwa dari 84 area potensi (RPA) yang diidentifi kasi dengan menggunakan data citraterdapat 37 RPA atau sekitar 44% berada pada struktur yang sudah terbukti menghasilkan hidrokarbon.Hasil pembobotan dari 84 RPA memperlihatkan 22 RPA dalam kategori sangat potensi, 38 RPA dalamkategori potensi, dan 24 RPA dalam kategori kurang potensi.

Abstract

Sub-Cekungan Bandarjaya terletak di Kabupaten Lampung Tengah, Provinsi Lampung. Secara tektonik kawasan ini merupakan bagian dari sub-Cekungan Palembang Selatan yang memanjang berarah baratlaut – tenggara. Stratigrafi sub-Cekungan Bandarjaya secara berurutan sebagai berikut: Batuan dasar berupa batuan metamorf sekis khlorit berumur pra-Tersier, di atasnya diendapkan runtunan batuan Tersier dari Formasi Lahat, Formasi Talang Akar, Formasi Baturaja, Formasi Gumai, Formasi Air Benakat , Formasi Muara dan Formasi Kasai. Potensi hidrokarbon di sub-Cekungan Bandarjaya teridentifikasi dengan ditemukannya beberapa rembesan migas dan dari hasil pemboran sumur eksplorasi (Ratu-1 dan Tujoh-1). Batuan induk hidrokarbon berasal dari serpih Formasi Lemat dan serpih Formasi Talang Akar, dengan tipe kerogen II-III, dan tingkat kematangan awal matang-matang (Ro 0,56-1%). Batuan reservoir utama batupasir dari Formasi Talang Akar dengan porositas antara 13 – 23%, dan Batugamping terumbu-bioklastik dari Formasi Baturaja dengan porositas berkisar antara12 – 18%. Migrasihidrokarbon secara vertikal melalui bidang-bidang patahan secara umum migrasi dari arah tenggara timur ke barat-baratlaut dengan tidak menutup kemungkinan terjadinya migrasi lokal. Perangkap hidrokarbon berupa perangkap struktur (antiklin yang berkombinasi dengan blok sesar) dan perangkap stratigrafi (pinch out). Berdasarkan analisis dan interpretrasi data seismik pada sub-cekungan ini dapat diidentifikasi 8(delapan) prospek, yaitu: LAF-1, LAF-2, TAF-1, TAF-2,TAF-3, BRF, GAF-1 dan GAF-2. Hasilperhitungan sumberdaya hidrokarbon pada masing-masing prospek menunjukkan awal isi sumberdaya minyak (original oil resources/OOIP)= 2.460.959,21 MSTB, sedangkan sumberdaya minyak yang dapat diambil (recoverable oil resources) sebesar =615.239,80 MSTB (Tabel 1).

Abstract

The decline in oil reserves and the increasing demand for oil and gas energy led to the search for new reserves. The geological structure pattern used to know the pattern of distribution and formation of hydrocarbons traps in the East Java Basin is one of the important information that can be extracted through remote sensing data of multi-polarization system. The multi-polarization system of this study merged the \ Alos Palsar imagery with HH and HV polarization, and Sentinel Image polarized VV and VH. Processing both image data through calibration, multilook, speckle fi ltering, geometric correction and mosaic. Filtered imagery is composite and sharpening. The fi ltering technique use Lee 5x5 kernel fi lter and then continue with 5x5 median fi lter. The results of multi-polarization system image interpretation can be identifi ed by fold, thrust faults, normal faults, strike-slip faults, bedding, and closure structure. In the formation research area the structure lasted two periods, with the main emphasis N-S in the order of 1 and the main direction of the SW-NE direction in the order-2. The hydrocarbon traps and exploration targets can be distinguished in three zones (Zone A, Zone B, and Zone C). Closure in Zone A includes closures 3, 4, 5, 7, 8, 9, 10, 11, 22, 23, 24, 25, 26, 27, 28, 29, 30. Closure in Zone B includes closures 1, 2, 6, 12, 13, 14, 15, 16, 17, 31, 32. Closure on Zone C includes closure18, 19, 20, 21.

Abstract

The oil and gas exploration activities in the last two decades in the mature sedimentary basins in the western area of Indonesia can be said has been in the stagnation phase. The activities are still limited in the effort of discovering shallow structures as the exploration targets which are of Miocene age and not older than Early Miocene. On the other hand, the oil and gas exploration on hydrocarbon plays, as well as new Paleogene sediments or others, has not been done intensively. Some problems which cause difficulty in finding new resources are such as lack of innovation in the exploration activities, and this is because the exploration operators are reluctant to bear the failure risk in the development of exploration activities that they do; which leads the exploration program carried out mainly focused only on the target or objective reservoir that is known. The effort of finding oil and gas resources in the future on the mature basins can be done by reanalyzing and revisit the evaluation on how the historical development of a sedimentary basin, that includes the development process and the tectonic sedimentation during the Tertiary era in relation to the formation of hydrocarbons. The reanalysis should be supported with the latest subsurface data, up-to-date geosciences concepts and sophisticated software and hardware which are able to perform the analysis of petroleum system in order to find new hydrocarbon-play as a new exploration target in the future. Various proposed activities in the re- valuation of the Tertiary sedimentary basins in Indonesia are the analysis of the Paleogene graben system of the back-arc basins of Sumatra and Java, the analysis of Miocene-Pliocene lowstand sediment, and the analysis of Miocene carbonate sediments, which have not been evaluated intensely so far.
