Determining Fluidization Across Gravel Pack Completion to Confirm its Integrity

The aim of this research is to understand the relationships determining pressure drop across an undamaged gravel pack such that the velocity for non-uniform inflow from the reservoir can be determined at the screen and at the sandface. Further, this study aims at determining the minimum inflow velocity sufficient to destabilize the gravel pack bed and thus, impair it, hence determine the minimum fluidization velocity. A CFD model for such a case hasn?t been done before in the oil and gas industry. We have created a model that describes the internal gravelpack dynamics of fluid and proppantPetroleum Engineering, Department o

Reducing the Green House Gas Emissions from the Transportation Sector

In the United States, two thirds of the carbon monoxide and about one third of carbon dioxide emissions come from the transportation sector. Ways to reduce these emissions in the future include replacing gasoline and diesel by biofuels, or by blend of biofuels with conventional gasoline and diesel, or by compressed natural gas (CNG), or by replacing internal combustion engines by electric motors powered by hydrogen fuel cells or battery-powered electric vehicles recharged from the electric grid. This presentation will review these technologies the fuel production pathways, when they are likely to be available, and by what fraction transportation sector green house gas emissions could be reduced by each. A well-to-wheels (WTW) analysis is performed on each vehicle/ fuel technology using the GREET model and the total energy use, the CO 2 emissions, NO x emissions, SO x emissions for the life cycle of the vehicle technologies are calculated. Prospects for reducing foreign oil dependence as well as mitigating green house gases emission from the transportation sector will be considered in the analysis

Proposal for Reservoir Engineering Studies in the State of Alaska

Alaska has a significant geothermal potential. While other sources of energy such as petroleum and coal are in abundance, there has been a definite move towards geothermal exploitation. The State has recognized the opportunity cost of petroleum as a source of materials and has expressed interest in the development of geothermal energy as a desirable and alternative resource. More than 11 million acres have been identified as potential geothermal reservoirs capable of producing electric power as well as direct heating. Reservoirs of the latter type are found in the interior of the state. Considering the winter temperatures of these regions (at times dipping to -60{degree}F) direct utilization is attractive. A comprehensive reservoir engineering proposal is presented to better assess the extent and potential of the geothermal areas in Alaska. The purpose of this paper is to acquaint the participants of the Stanford Geothermal Workshop with the enormous potential, as yet untapped, of the State of Alaska
