Abstract

"The Paleocene strata in Sirte Basin, Libya, contain major oil and gas accumulations in a variety of lithofacies of reef and bioherm carbonate depositional environments. The Upper Paleocene Khalifah Formation, which is one of the main reservoirs containing about 30% of the oil reserves of the Sirte Basin, is composed of shallowing-upward and carbonate platform deposits and is capped by open marine shale deposits formed during a marine transgression. Well and seismic data are used to interpret the depositional environments and identify upward shallowing and deepening trends in the formation. In the study area, Mabruk oil field in northwestern Sirte Basin, three level of low, intermediate, and high-order cycles are delineated in Khalifah Formation. Six low-order cycles are interpreted within the formation. Structural and isopach maps show a paleohigh, which was formed by structural and stratigraphic processes. The first four low-order cycles are progressively thickening upward, probably indicating platform and reef buildup, the fifth low-order cycle is the thickest and indicates keep up mode of platform deposition. The uppermost cycle is thin and well bedded and defines the end of a reef buildup cycle"--Abstract, page iii.
