Wellbore instability is one of the major problems that hamper the drilling speed in Halfaya Oilfield. Comprehensive analysis of geological and engineering data indicates that Halfaya Oilfield features fractured shale in the Nahr Umr Formation. Complex accidents such as wellbore collapse and sticking emerged frequently in this formation. Tests and theoretical analysis revealed that wellbore inst...
The characterization of fluid-transport properties of rocks is one of the most important, yet difficult, challenges of reservoir geophysics, but is essential for optimal development of hydrocarbon and geothermal reservoirs. Production of shale oil, shale gas, heavy oil and geothermal energy, as well as carbon-dioxide sequestration, are relatively recent developments where borehole fluid injecti...
The development of engineering activities involving shales such as the extraction of shale gas and shale oil, the nuclear waste geological storage and the sequestration of CO2, has led to an increasing interest toward the geomechanical behaviour of this geomaterial. In the context of such engineering applications, a deep understanding of the hydro-mechanical behaviour of shales is of primary si...
This study proposes to collect long term production data from wells in many different shale basins and evaluate well performance using production data analysis (PDA) with both rate and pressure data where possible, and rate transient analysis (RTA) when only rate data is available. Also, we propose to request injected fracture fluid volumes in order to quantify load recoveries and horizontal we...
-The extent of illite/smectite (I/S) reactions is linked with quantitative measurements of shale fabric in a suite of samples from a lower Frio Formation well. Greater illitization of the I/S clays is found in laminated shales that possess a larger pore surface area/pore volume (SA/V) of 3.21 x 106 cm-~ than the adjacent massive shale lithofacies with a SA/V of 1.97 x 106 cm -~. Mean pore diame...
al., 2002; Gallagher and Koch, 2003). It is based on slow injection of stabilizing materials at the up-gradient edge Passive site stabilization is a new technology proposed for nondisof a site, with subsequent delivery of the stabilizer to ruptive mitigation of liquefaction risk at developed sites susceptible to liquefaction. This technology is based on the concept of slow injecthe target locat...
Environmental and occupational health concerns will have an effect on the developing oil shale technologies. The mining and crushing of large volumes of rock will be a characteristic of at least some of these technologies, and above ground disposal of proceessed shale will require adequate control measures. Exposure by inhalation to the dusts that may arise from shale oil technologies may prese...
