ABSTRAKSecara geografis daerah penelitian terletak pada koordinat 114 0 32' -116 0 01' Bujur Timur dan 07 0 15' -08 0 02' Lintang Selatan. Kondisi geologi dasar laut belum banyak dibahas oleh para peneliti di Perairan Bali Utara, karena kurangnya data seismik dan data sumur bor. Cekungan Jawa Timur di sebelah selatan dibatasi oleh busur vulkanik, sebelah timur dibatasi oleh Cekungan Lombok. Stratigrafi daerah penelitian dari tua ke muda terdiri dari formasi Prupuh, formasi Rancak, formasi Cepu, formasi mundu dan formasi Lidah. Metoda penelitian terdiri dari pengukuran navigasi, pengukuran kedalaman dasar laut, pengukuran seismik 2D serta kesebandingan data seismic dan bor. Tujuan penelitian adalah mengetahui pelamparan Cekungan Jawa Timur utara di Perairan Utara Bali. Dari hasil interpretasi dan korelasi antara data seismik dengan sumur bor, menunjukkan bahwa rekaman seismik 2D daerah telitian dapat dibagi menjadi enam (6) runtunan dengan urutan dari atas ke bawah adalah runtunan A, ABSTRACTGeographically the research area lies within coordinates of 114 0 32' -116 0 01' East and 07 0 15' -08 0 02' South. The geological condition of the seabed has not been much discussed by researchers in the North Bali Waters, due to the lack of seismic and well data.The East Java Basin to the south is bounded by a volcanic arc, whereas the Lombok Basin on its eastward. Stratigraphy of research area consists of old to young Formation, i.e., Prupuh, Rancak, Cepu, Mundu and Lidah formation. Method consists of positioning, bathymetric, 2D seismic measurement, and compiled by seismic and well data.

“…The province is less rich in oil and gas than the western part of the country, but is less well-known and exploration is certain to reveal new insights. Both thermogenic and biogenic gas (>98% methane) has been discovered, the latter in fore-arc and foreland basins (Satayana et al, 2007). Characteristic for the area is the presence of prospective Mesozoic rocks of Australian continental affinity that underlie the Tertiary basins (Bradshaw et al, 1997).…”

Petroleum systems in Southeast Asian Tertiary basins

Productive Tertiary basins in Southeast Asia have essentially similar geodynamic developments, and share many hydrocarbon habitats and active petroleum systems. In order to facilitate understanding of the essential elements that contribute to the success of petroleum systems I have classified them into a number of groups or 'associations' according to their sedimentary facies. This facilitates use of them as valuable analogues. Five such facies associations, containing characteristic and distinct petroleum parameters have been recognised: (i) lacustrine (ii) paralic (iii) open marine shelf (iv) deeper marine and (v) pre-Tertiary. They belong to particular cycles or stages in basin development that provide the context within which the depositional environments and palaeogeography evolve. Lacustrine facies typify the early stages of synrift development in basins closer or more proximal to the Sundaland province in northern and western SE Asia. Open marine facies, on the other hand, typify the early postrift period and basins in palaeogeographically more distal areas, such as eastern Indonesia and The Philippines. Paralic and bathyal facies characterise the later stages of the synrift and postrift cycles and are widespread throughout the proximal and intermediate parts of the area. Pre-Tertiary source facies, which provide charge in parts of eastern Indonesia and Thailand, are mainly terrestrial in nature. These differences have important implications for petroleum occurrence, which can be summarised accordingly: • More proximal basins are dominated by lacustrine to paralic facies in the synrift cycle and have a mainly nonmarine sedimentary fill. Petroleum systems with oil charge are dominant. • More distal basins are dominated by rapid postrift subsidence. In the open marine facies carbonate reservoirs are well-developed, while petroleum systems are mainly gas-prone. • Around Borneo thick late postrift passive margin delta sequences with oil-and gas-prone coaly source rocks and clastic reservoirs are developed in delta-top environments. Transported terrigenous organic material is commonly found in related deep marine environments and contributes to a marine source facies. Both give rise to prolific petroleum systems. • Many basins in the Sunda Shelf area lie in an intermediate situation, where a non-marine synrift is followed by a marine postrift cycle. Such basins benefit from lacustrine and paralic source rock and reservoir sequences in both the syn-and the postrift, and are often characterised by multiple petroleum systems. Evaluation of petroleum potential in Southeast Asian Tertiary basins requires a special approach: in most parts of the World, such as the Middle East and Northwest Europe, source rocks are of marine origin, are relatively consistent in type and quality and are located in well-defined formations of regional extent. In SE Asia the terrestrial and lacustrine source rocks are more difficult to locate, are variable in quality and are often distributed in thin beds throughout thick sequences. These...

“…Furthermore, the sea floor geochemistry identified large amounts biogenic gas seepage. This is encouraging for biogenic gas plays which are known to occur in North Papuan basins (Satyana et al, 2007).…”

“…The source of the hydrocarbons has not been proven conclusively, but is likely to be within the Neogene section (Makat and Memberamo formations). Biogenic gas is also important, as seen in Mamberamo sandstone reservoirs of the Niengo-1 well which flowed gas on test (Satyana et al, 2007).…”
