Abstract

Although revenue from the oil and gas industry is no longer the main source of national income, it is still playing a strategic role. The oil and gas industry is known as a high-tech, a high-risk, and a high-capital industry, on which the country has limited capacity for regional development, especially of the resources in areas located along the national border. The main objective of this research is to closely identify the recent growth centre status of blocks and sedimentary basins located along the national border. The study relies on published reports, studies, and data such as bathymetry map, national geographic and jurisdiction map, and maps of existing oil and gas blocks. All data were managed under a geographic information system application in order to conduct comparative and qualitative analysis of those overlaying data. Some oil and gas blocks that are located near to neighboring countries, such as Singapore, Malaysia, Brunei, Vietnam, The Philippines, Papua New Guinea, East Timor, and Australia have been categorized based on these methods of scoring and ranking analysis to identify new economic centres of growth. Three categories are suggested: very important, important, and ordinary as new growth centres. The Natuna Sea blocks, Iwur, and Timor blocks are considered to be important.

Abstract

Kegiatan eksplorasi dan produksi migas saat ini terkonsentrasi di Kawasan Barat Indonesia, yaitu Sumatera, Jawa, Madura, dan Kalimantan. Di Kawasan Timur Indonesia kegiatan eksplorasi dan eksploitasi minyak dan gas bumi masih kurang berkembang. Konsentrasi eksplorasi dan eksploitasi migas masih pada cekungan produksi dan cekungan dengan penemuan hidrokarbon. Pada Kawasan Timur Indonesia peluang untuk mendapatkan sumberdaya migas masih terbuka karena masih banyak cekungan yang belum dilakukan pemboran. Pada kajian ini dilakukan analisa tumpang susun (overlay)untuk mengkaji cekungan yang secara geologi dan geofisika mempunyai peluang terbaik untuk mendapatkan migas. Analisa tumpang susun dilakukan menggunakan data cekungan sedimen, wilayah kerja migas, lintasan seismik, rembesan migas, penemuan migas, lapangan migas, dan anomali gaya berat. Hasil analisis diperoleh 3 kategori cekungan untuk dikembangkan.Kategori pertama terdiri atas 7 cekungan yang terbukti telah ditemukan hidrokarbon, yaitu cekungan Laut Timor, Bone, Makassar Selatan, Banggai, Seram, Salawati dan Bintuni. Kategori kedua terdiri atas 16 cekungan yang terbukti ditemukan adanya rembesan minyak atau gas dan oil shows pada sumur migas, dan Prioritas ketiga terdiri atas 24 cekungan yang merupakan cekungan frontier.  Oil and Gas Exploration and exploitation recently, has been concentrated in the Western Indonesia i.e.: Sumatera, Java, Madura, and Kalimantan. In Eastern Indonesia this activity less developed compared to Western Indonesia. Recently, concentration of the oil and gas activity is still in hydrocarbon producing basin and hydrocarbon discovery basin. In eastern Indonesia the probability to discover hydrocarbon resources is high, this is because many sedimentary basins has not been drilled yet. In this study, an overlay analyses is applied to the sedimentary basin geologically and geophisically with expectation to find best probability to discover oil and gas. This analyses is conducted by overlied some data, ie: sedimentary basin, oil and gas block, seismic line, oil and gas seeps, oil and gas discovery, oil and gas field, and anomaly gravity. This analyses reveal 3 classes of sedimentary basin to be developed. Class one which consists of seven sedimentary basins was hydrocarbon proven, i.e.: Laut Timor, Bone, Makasar Selatan, Banggai, Seram, Salawati, and Bintuni. Class two which consists of sixteen sedimentary basins, proves the occurrence of hidrocarbon seeps and oil shows, and Class three which consists of twenty four sedimentary basins as frontier sedimentary basin.

Abstract

Teknologi informasi pada eksplorasi dan pengembangan wilayah migas merupakan teknologi yang penting. Salah satu aplikasi Sistem Informasi Geograsebagai alat pada pengembangan wilayah migas yang secara menerus memerlukan inovasi. Makalah ini bertujuan menyampaikan aplikasi teknologi informasi khususnya Sistem Informasi Geogra(SIG) guna mendukung inovasi dalam pengembangan wilayah migas berkelanjutan. Metode yang digunakan adalah aplikasi Sistem Informasi Geogra(SIG) dalam pengelolaan data geologi, geosika, dan reservoir. Analisis tumpang susun (overlay) dilakukan untuk memilih wilayah migas di Cekungan Kutai, Kalimantan Timur. Hasil analisis tumpang susun terhadap data geologi bawah permukaan diseleksi pada wilayah awal kajian seluas 59.350 kilometer persegi. Dari pemilihan blok migas berdasarkan data kedalaman batuan dasar hasil olah magnetik, data seismik dan sumuran, direkomendasikan blok migas baru. Hasil perhitungan sebagai data baru wilayah blok migas untuk usulan pengembangan Cekungan Kutai seluas 5.425 kilometer persegi. Sedangkan wilayah penyimpanan CO2 di cekungan sedimen lepas pantai Indonesia seluas 453,970 kilometer persegi. Operator atau perusahaan migas selama ini sudah memanfaatkan SIG pada lapangan yang memiliki ratusan bahkan ribuan sumur di daerah yang sulit dijangkau (remote area). Disimpulkan, SIG mampu mengorganisasi dan mengintegrasikan banyak data untuk penyiapan wilayah migas, evaluasi, meningkatkan akurasi dan kecepatan dalam perhitungan luas wilayah dan sumberdaya migas, pemilihan lokasi penyimpanan CO2, hingga dapat mempercepat pengembangan wilayah migas berwawasan lingkungan. Information technology on the exploration and development of oil and gas area is an important technology. One of the applications of Geographic Information Systems (GIS) in the area of oil and gas development requires constant innovation. This paper aims to convey the application of information technology, especially Geographic Information System (GIS) to support innovation in the sustainable development of oil and gas area. The methods used is the application of GIS in the management of geological, geophysical, and reservoir data. Overlaying analysis for the selection a potential area of oil and gas in the Kutai Basin, East Kalimantan. Overlying analyses was conducted over initial coverage of 59,350 square kilometers. The potential areas are dened considered to basement depth from magnetic, seismic and well data, was recomended new block. The result as new data of the calculation of oil and gas area as proposed to be the development of Kutai basin is 5.425 square kilometers. While the deposit area of CO2 in the Indonesian sedimentary basin offshore as wide as 453,970 square kilometers. Oil and gas companies so far have been utilizing GIS in the eld who have hundreds or even thousands of wells in remote area. In conclusions the SIG can organizing and integrate a lot of data for the preparation of oil and gas area, evaluation, is able to improve the accuracy and speed in the calculation of area and resources of oil and gas, CO2 storage site selection, to be able to accelerate the development of environmentally sound oil and gas area.
