Unformatted text preview: S H A L E O I L : E x p l o r a t i o n a n d D e v e l o p m e n t Presented By: Justin Brady, Laura Kerr, Mike Potts Senior Capstone Project Spring 2006 Current Energy Crisis • World’s main source of energy: Petroleum • Demand exceeding supply – April 17, 2006: Oil reaches $70/barrel • Opportunity to develop alternate energy sources – Large economic incentive Why Shale Oil? • Currently, United Arab Emirates hold 50% of world’s known oil reserves How much does the US hold? 2% How many reserves would be added from developing oil shale? 2 TRILLION BARRELS • Result: US takes over as leader in the world in oil reserves. Outline • Introduction to Shale Oil • Project Statement • Subsurface Operations – Reservoir Temperature Profiles – Heating – Freeze Walls – Reservoir Composition Analysis • Surface Facilities – Oil/Gas Processing – Power Plant • Pipelines to Market • Production Schedule • Economics and Risk Shale Oil: Definition • Sedimentary rock with a high organic content – Organic matter is known as kerogen • Kerogen: – MW avg. =3000 – Approximate formula C 200 H 300 SN 5 O 11 1 1. Feng H.Y. Rates Of Pyrolysis Of Colorado shale oil. p. 732. American Institute Of Chemical Engineers Journal . Vol. 31 No. 5. 1985. Shale Oil: History in the US • Office of Naval Petroleum and Shale Oil Reserves formed in 1912 • First Demonstration mine opened outside of Rifle, Colorado just after World War II Shale Oil: History in the US • TOSCO opened an experimental mine and production plant near Parachute, Colorado in 1960’s • Exxon opens Colony II project outside of Parachute, Colorado in 1980 – Colony Project is closed in May of 1982 – Nearly 2,200 people unemployed – Loss of more than $900 million. Project Statement • Determine which method of production of shale oil is the most feasible. • Analyze production process to determine – Subsurface designs – Reservoir characteristics – Surface processing facilities – Scheduling of project – Pipelines • Perform an economic analysis on project. Shale Oil Production Methods Above Ground Retorting • Mining of ore • Well known technology • Large environmental impact – Popcorn effect – Large open mines – Emissions In-Situ Conversion • Underground conversion • Research in progress • Lower environmental impact • Not commercially proven In-Situ Conversion • Currently being explored by Shell Oil with the Mahogany Project. • Entails the heating of kerogen in the ground and extracting the produced hydrocarbons for further processing. In-Situ Process Overview • Step 1: Heating – Conversion of kerogen to oil and gas • Step 2: Freeze Wall Construction and Water Removal – Impermeable wall around production site – Prevents large environmental impact 1. Mut, Stephen. The Potential of Oil Shale. 8/20/05 In-Situ Process Overview • Step 3: Production – Products from kerogen conversion • Step 4: Processing and Transportation – Oil and gas separation – Pipelines to market Schedule Table...
