Quantification Of Geodetic Strain Rate Uncertainties And Implications For Seismic Hazard Estimates, Jeremy Maurer, Kathryn Materna

Geosciences and Geological and Petroleum Engineering Faculty Research & Creative Works

Geodetic velocity data provide first-order constraints on crustal surface strain rates, which in turn are linked to seismic hazard. Estimating the 2-D surface strain tensor everywhere requires knowledge of the surface velocity field everywhere, while geodetic data such as Global Navigation Satellite System (GNSS) only have spatially scattered measurements on the surface of the Earth. To use these data to estimate strain rates, some type of interpolation is required.

Carbon Fibers From Athabasca Oil-Sand Asphaltenes, Blake Reardon

All Theses

Carbon fibers possess ultra-high specific strength and modulus. Therefore, the material is popular in aerospace, automotive, and sports industries. Approximately 95% of all carbon fibers are spun from a high-cost precursor, polyacrylonitrile (PAN). There is a need for a cheaper grade of carbon fiber for low-cost applications because about half of carbon fiber cost is associated with precursor cost. A promising alternative to the high-cost PAN precursor is petroleum-based asphaltene. Asphaltenes are highly aromatic and have a high carbon content but lack the purity of the PAN precursor. Processes like the molten- sodium desulfurization upgrading have been used to harvest …

Reasons Why Oil Reserves Remain Unproductive-A Case Study, Mohamed Al-Saho

Journal of the Arab American University مجلة الجامعة العربية الامريكية للبحوث

By studying the production plans of some wells of Al Furat Petroleum Company, the researcher noticed that the rate of production increases to reach a peak and then falls back sharply. The deformation of the area around the well due to the decrease in the formation pressure (after production for a certain period) may have caused a change in the storage properties (porosity, permeability) and thus lower production rate. However, from the point of view of the geomechanics of the oil formation, which includes the study of the stress situation and its effect on the rock tissue, we will notice …
