Available in PDF, EPUB and Kindle. Book excerpt: A series of field experiments was carried out to gather preliminary information on the use of propellant charges to create horizontal fractures in oil shale beds for in situ retorting. Development of a propellant tool specifically designed to create horizontal fractures, and testing of various sizes and designs of the tool to create fractures in oil shale beds were carried out simultaneously. Ten prototype tools with energy yields from 2 pounds to 60 pounds were fired at depths ranging from 10 feet to 60 feet. Ten preshot observation holes and 13 postshot core holes were used to gather information and to serve as injection wells to inject air into the formation for permeability tests. Most shots vented large volumes of gas or water from observation holes 13 to 20 feet distant, indicating that a horizontal fracture communicating from the shot point to the observation hole had been created. Shot-related horizontal fracturing was noted in most core holes at the same depth as the shot point. Air injection tests on all holes showed a significant increase in permeability after the shots.

Available in PDF, EPUB and Kindle. Book excerpt: A true in situ oil shale fracturing and retorting experiment was conducted near Rock Springs, Wyoming in 1977, 1978, and 1979. A 20-foot (6.1 m) thick zone of oil shale located 200 feet (61 m) below surface was hydraulically and explosively fractured. The fractured oil shale was extensively evaluated using flow tests, TV logging, caliper logging, downhole flow logging, core samples, and tracer tests. Attempts to conduct true in situ retorting tests in portions of the pattern with less than 5 percent void space as measured by caliper logs and less than 1 percent active void space measured by tracer test were curtailed when air could not be injected at desired rates. It is thought the fractures plugged as a result of thermal swelling of the oil shale. Air was injected at programmed rates in an area with 10 percent void measured by caliper log and 1.4 pecent active void measured by tracer test. A burn front was propagated in a narrow path moving away from the location of the production well. The vertical sweep of the burn front was measured at less than 4 feet (1.3 m). The burn front could not be sustained beyond 10 days without use of supplemental fuel. The authors recommend a minimum of 5 percent well-distributed void for attempts to retort 20 gpt (81 L/m ton) oil shale in confined beds. A void space of 5 percent may be roughly equivalent to 5 to 10 percent measured by caliper log and 1.4 percent or more by tracer test.

Available in PDF, EPUB and Kindle. Book excerpt: The hot-film sensor technique of fluid flow measurement has been developed and is being applied to well logging for evaluating in situ fracturing and retorting experiments in the Green River Formation oil shale of Wyoming. Natural, hydraulic, and/or explosive fractures in oil shale have been evaluated by air injection and production flow logging techniques. Fracture depths, types (horizonal or vertical), and flow characteristics within a system of wells designed for an in situ combustion test have been determined before and after fracturing. Gas flow profiles were also determined before ignition, during combustion, and after combustion termination.
