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…

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…
Modelling subsurface deposits is extremely challenging with limited subsurface datasets such as cores, wireline logs and seismic data. However, integrated studies, which rely on extensive subsurface datasets can lead to improve the quality of spatial and temporal distributions o…
Large-scale sandstone injectite complexes located in California and in Tunisia have exposures of external geometries and sedimentary structures. Substantial macroscale erosion occurred along the margins between the injected sandstones and host mudstones that include scalloped up…
This thesis investigates the origin of large-scale sandstone intrusions. A new approach combining seismic, well data, core and outcrop observations with numerical modelling has been undertaken. Two possible end members of saucer-shaped, seismic-scale sandstone intrusions from th…
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…
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…
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…
