One of the widely used hydrocarbon maturity parameter was vitrinite reflectance (Ro) The effectiveness of this technique had been proven good if it was used for coal sample But, its effectiveness was relatively declining if it was used for determining source rock, especially if that source rock contained relatively high hydrogen In this case, the va…
Fifteen newly determined radiocarbon dates indicated the presence of former shorelines up to 3 meters above present high tide level in the tectonically stable Peninsula of Malaysia. The sea level indicators consist of oysters in growth position (9 sampels), moulluscs in beach deposits (2), corals in growth position (3), and beachrock (1). In the Pen…
Recent advances in seismic technology are providing the tools for accurate and effective delineation and quantification of hydrocarbon bearing strata. Llimits of resolution have been significantly reduced so that it is common to provide pay thickness maps at 10 foot contour levels from seismic data alone. In addition, it is possible to establish pos…
Geochemical prospecting (or exploration) methods for petroleum and natural gas deposits at and near the surface of the ground and the offshore area have not achieved the popularity of geophysical methods. Geochemical methods have been used widely in both the united states and the soviet union, and many new discoveries have been reposrted from these …
In the Java sea Tertiary sediments cover a cratonized basement of pretertiary age. Tentative standard sections of the Tertiery sequence employ used stratigraphic nomenclature. Regional lithologic correlation provides a consistenst picture of alternating carbonate and clastic series covered by a clay series. This corelations is substantiated by paleo…
The Arum Gas Field is Located in The Special Province of Aceh in North Sumatra. The field straddles the coastal plain between the Barisan Mountains and the strait of Malacca, 225 Kilometers northwest of Medan. Condensate rich gas is found in reef and associated carbonates of Lower and Middle Miocene age which in place exceed 1000 feet in thickness. …
Over the past several decades the philosophy of exploration for oil and gas has pro• gressively changed from drilling on surface seepages to the concept of structural traps, com• plemented later by considerations of sedimentology in relation to the development of reser• voirs, which led to the concept of stratigraphic traps. …
•The petroleum geochemist seeks to determine if rocks contain organic quantity and o~ the appropriate type to source those rocks have been heated sufficiently to allow the He will also try to ~stkblish if hydrocarbons have been generated before, and faulting, and if the rate of heating has varied with time associated wiith tectonic causes. Jf …
Since the discovery of Kasim oil field in 1972, some eighty-five wells have been drilled by Petromer Trend in the Salawati Basin. This subsurface information, together with earlier Shell Oil and Pertamina
data, provides a fairly complete picture of basin history with its Miocene reef growth, burial, tilt and subsequent deformation. Until Eocene tim…
