Title: Contribution of satellite altimetry to the study of the spatial and temporal variability of water level in the Inner Delta of Niger River Content: The radar altimeter was originally developed to contribute to the study of ocean waters dynamics. The large size of oceans an…
Geomechanical processes occurring during steam assisted gravity drainage (SAGD) thermal recovery influence petrophysical and rock mechanical properties of both reservoir and caprock formations. While geostatistical techniques provide multiple equiprobable geological realizations…
The Wax Lake Delta (WLD) is located at the downstream end of the Wax Lake outlet, approximately 13 miles upstream from Morgan City, Louisiana. In 1942 the United States Army Corps of Engineer (USACE) dredged Wax Lake Outlet channel from the lower Atchafalaya River to reduce floo…
This dissertation aims to advance the state-of-the-art in measuring and predicting weak rock mass modulus in a variety of geotechnical conditions. This goal has been accomplished by collecting in-situ data from underground mines in Nevada and by reappraisal and critical review o…
Field X is a naturally fractured reservoir, part of a large system of carbonate reservoirs located in North Caspian basin in western Kazakhstan. Predicting the movement of hydrocarbons in such reservoir is challenging because of the many uncertainties due to the complicated frac…
This work is conducted to study the complications associated with the sonic log prediction in carbonate logs and to investigate the possible solutions to accurately predict the sonic logs in Traverse Limestone. Well logs from fifty different wells were analyzed to define the min…
The research conducted here is an attempt to develop a simulation framework of CO2 sequestration in geologic formations. One of the very important parts of this framework is centered on phase equilibrium computations between CO2 and Brines for a wide range of temperature and pre…
The Hunter Creek sandstone near Mogul, Nevada, is a Neogene sedimentary unit in the Verdi basin consisting of fluvial, deltaic, and lacustrine facies. Numerous slope failures have occurred in the unit mostly along streams, canals, and the Truckee River. Field mapping showed that…
Design of buried pipeline systems involves solution of geotechnical and structural problems in addition to the hydraulics and mechanical issues. Just like any buried structure, it is of utmost importance to understand how the pipe interacts with the soil when subjected to extern…
An experimental study of the monotonic and cyclic response of Fraser River sand under triaxial loading has been conducted. Effects of a wide range of initial states characterized by the magnitude and the direction of the initial static shear stress level, loading mode, relative …
The objectives of this study were to evaluate the effects of soluble salt concentration (i.e., salinity) on geotechnical characteristics and sedimentation behavior of fine-grained soils (e.g., mine tailings) and identify test methods applicable for characterizing high-saline soi…
This thesis is a summary of a comprehensive geophysical investigation in southern Dawmat Al Jandal, Al Jawf in Saudi Arabia. This research demonstrates that the acquisition of both core control and geophysical data is superior to the acquisition of core control alone. Coring is …
The rugged elevated topography is a characteristic feature of the western and southwestern regions of Saudi Arabia. Few arterial roads connect the scattered villages of these regions to major cities, such as Habs Road in Jazan region. Rock fall poses a serious hazard to people, …
A spatial landslide inventory is a fundamental step preparatory to developing an understanding of regional landslide hazards. The techniques honed for this regional landslide mapping study began with compiling a stitched shaded topographic map of the Upper Indus River watershed;…
With advances in sensor technology and the inclusion of low cost consumer grade sensors in portable systems like smart-phones, pedestrian navigation using such devices has become a reality. With consumer grade sensors comes a Pandora’s Box full of errors rendering the unaided na…
This study investigated the differences in the cutting performance of two rock cutting tools in dry and saturated rock. For this purpose, a permeable quartzose sandstone was subjected to a series of full scale linear rock cutting tests, in both dry and saturated conditions, usin…
