Characteristics of Rock-Eval Analysis of Carbonates Source Rocks and of Petroleum Derived from Carbonate Source Rocks.

Thermal modeling and organic geochemical appraisal of petroleum source rocks within the Aghajari Oilfield, SW Iran

Dezful embayment contains several potential source rocks deposited in tectonically active environments. Existence of various source rocks with different geological ages makes this area one of the most prolific regions throughout the Middle East. The Pabdeh Formation (Lower Paleocene-Eocene), the Gurpi Formation (Santonian-Masstrichtian), the Kazhdumi Formation (Albian) and the Gadvan Formation ...

Geochemical Evaluation of Oils and Source Rocks and Oil-source Rock Correlations, Sub-andean Basins, Peru

Brunei Darussalam Characteristics of selected petroleums and source rocks

The development of three Tertiary deltaic complexes has resulted in the deposition of up to 10 km of sandstones and shales comprising the sources and reservoirs for crude oils that occur onshore, near-o€shore and, with future exploration e€orts, those likely to be encountered in deepwater reservoirs north of the Brunei coastline. We examined a series of o€shore oils and onshore rock samples in ...

Petrographic Characteristics and Fluid Inclusion Study of Carbonate Cements in Permian-Triassic Rock Sequence of Southern Iran: an Implication of Rock-fluid Interactions in Carbonate Reservoir Rocks

The study of the carbonate cements in the Permian-Triassic Dalan-Kangan formations resulted in the identification of five stages of calcite and dolomite cementation, which completely or partially occluded pores. Cement types appear to be early isopachous calcite (i; C1-non-luminescence), equant (ii; C2-dull CL), fairly coarse secondary dolomite rhombs (iii; C3-zoning red CL), coarse sparry calc...

Petroleum Source Rock Logging

Regional distributions of organic content are an important aid in developing basin evolution and hydrocarbon generation models. An approach to evaluate hydrocarbon source rocks using resistivity, sonic, density, neutron and natural gamma ray logs is developed. Organic matter, as a constituent in sedimentary rocks, has a relatively low density, slow velocity, and is high in hydrogen content. Sou...
