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...
متن کاملEvolution of the Kap Edvard Holm Complex : a Mafic Intrusion at a Rifted Continental Margin
The Kap Edvard Holm Layered Series forms part of the East Greenland Tertiary Province, and was emplaced at shallow crustal level (at depths corresponding to a pressure of 1-2 kbar) during continental break-up. It consists of two suites: a gabbro suite comprising olivine and oxide gabbros, leucocratic olivine gabbros and anorthosites, and a suite of wehrlites that formed from the intrusion of th...
متن کاملSource Rock evaluation, Modelling, Maturation, and Reservoir characterization of the Block 18 oilfields, Sab’atayn Basin, Yemen
A total of 183 core and cutting samples from seven exploratory wells were selected to be analyzed by Rock-Eval pyrolysis. These cores have been drilled through the Lam and Meem Members of the Madbi Formation and contain the major source rocks of Yemen´s sedimentary basins. Contents of total organic carbon were measured and Rock-Eval pyrolysis was performed to evaluate the hydrocarbon potential ...
متن کاملSilicic volcanism: An undervalued component of large igneous provinces and volcanic rifted margins
Silicic volcanic rocks are associated with most, if not all, continental ×ood basalt provinces and volcanic rifted margins, where they can form substantial parts of the eruptive stratigraphy and have eruptive volumes >104 km3. Poor preservation of silicic volcanic rocks following kilometer-scale uplift and denudation of the volcanic rifted margins, however, can result in only deeper level struc...
متن کاملLake-type controls on petroleum source rock potential in nonmarine basins
Based on numerous empirical observations of lacustrine basin strata, we propose a three-fold classification of lacustrine facies associations that accounts for the most important features of lacustrine petroleum source rocks and provides a predictive framework for exploration in nonmarine basins where lacustrine facies are incompletely delineated. (1) The fluvial-lacustrine facies association i...
