چکیده
Abstract The present work aims to investigate the reservoir characterizations of Lower Cenomanian Baharyia Formation by creating isoparametic maps calculate petrophysical parameters and detect favorable parts for oil accumulations using available well logging data. is one main hydrocarbon sandstone reservoirs in northern Western Desert Egypt. About 90% field produces form Formation. This has been achieved through analyses conventional wireline logs modeling. comprises a complex depositional lithofacies such as interbedded siltstone, shale, sandstones pebbly sandstones. Petrophysical modeling was performed, based on interpretation complete from five wells Razzak field, north desert, analysis accomplished, as: shale volume, total effective porosities, water saturation saturation, were deduced utilized subdivision Relations between theses are established define implications Iso-parametric litho-saturation crossplots used delineate variations across area. obtained results reveal that, have good quality, with high porosity values exceeding 18%,volume about 30% low 25%. rock genetic types log curve shapes proved that deposited fluvial marine environments passing tidal flood plain conditions. However, lithology composed sandstone, minor limestone inter-beds.

We evaluate new lungfish remains from the Upper Cretaceous Quseir Formation in the Western Dessert of southern Egypt. Taxa include Lavocatodus protopteroides, L. humei, L. giganteus, and Protopterus nigeriensis. We treat Lavocatodus as members of Lepidosirenidae based on the presence of a well-defined medial articular surface, in the absence of a symphyseal surface of corresponding prearticular...

abstract: mineral scaling in oil and gas production equipment is one of the most important problem that occurs while water injection and it has been recognized to be a major operational problem. the incompatibility between injected and formation waters may result in inorganic scale precipitation in the equipment and reservoir and then reduction of oil production rate and water injection rate. ...
