Techno-Economic Study of Renewable Energy Integration in the Upstream Oil Supply Chain (USOSC)

Abstract

The production of oil requires tremendous amounts of energy consumption through a distributed combustion network of processes along the oil supply chain spectrum. The consequences of fossil-based fuel combustion processes are the generation of Greenhouse Gas (GHG) emissions and hazardous wastewater, which have adverse environmental effects. Potential mitigation options of GHG emissions are the application of renewable and alternative energy sources. This research deals with integrating the upstream oil supply chain with renewable power generation systems in order to assess the impact of energy demand, and CO2 emissions on the efficiency of oil operations and environment . The main focus in this thesis is to evaluate the solar energy alternative for producing part of the energy requirements in the upstream oil supply chain. The output from the research will provide an optimal mix of energy generation in the upstream oil industry in order to comply with CO2 constraints, while sustaining target production plans. An analysis of GHG emission sources and their associated flow rates in the upstream oil supply chain mainly CO2 is discussed in this study. An investigation of replacement of energy supply for some non-critical operations from fossil fuels or other conventional sources to green renewable energy sources mainly from solar energy is also carried out with special focus on enhanced oil recovery operations. An analysis of different types of solar energy and identification of the best type of solar energy technologies that best matches the oil and gas industry is investigated in this study. The thesis will also identify the challenges for solar energy integration including irradiation levels and weather conditions in addition to policy regulations
