Experience has shown that the response of oil wells to sandstone matrix acidizing is different from the response of gas wells. For oil wells, the improvement in permeability resulting from the stimulation treatment peaks at a certain acid volume and then decreases as the acid vo…

The Lower Acacus Formation consists of fourteen deltaic packages which change laterally across the Hamada Basin, NW Libya. Southern fluvial-channel sandstones prograded northward into coastal-deltaic sandstones and siltstones, and eventually to offshore-marine sandstones and sha…

The Early Miocene Bekasap "A" Formation of the Sihapas Group occurs at a depth of 4400 to 4900 feet (1333.3 to 1484.8 meter) and ranges from 60 to 160 feet (18.2 to 48.5 meter) in thickness. There are commonly four sandstones, the Bekasap A-1, A-2, A-3, and A-4 members, separate…

This study uses changes in facies, paleoccurents, and provenance to reconstruct the depositional history of Upper Cretaceous through Plio-Pleistocene sandstones in the northern and southern ends of the Sulaiman Range, north-central Pakistan. Pre-orogenic Cretaceous shelf sandsto…

The objective of this research was to experimentally investigate transport properties such as capillary trapping, relative permeability, dispersivity, and capacitance parameters of micellar fluids under single- and two-phase flow conditions. Low interfacial tension, brine-oil-su…

This doctoral dissertation constitutes a reservoir characterization and tertiary recovery improvement of the Weber Formation, northwest Colorado. The Weber formation was deposited in an ancient desert environment and consists of intertonguing eolian dunes and fluvial deposits. S…
