Fracture stimulation is commonly used for coal degasification at the Black Warrior basin in Alabama. To understand coalbed fracturing better, Well AM-1 in the Oak Grove field was completed openhole in the section bracketing the Black Creek coals. Special diagnostics used on this project included various injection tests, static-line pressure measurements, and a downhole television camera. The television camera observed fractures during injection tests and after the propped fracture treatment. The authors believe these are the first successful downhole television pictures of propped fractures in coalbeds. Results are compared with predictions of hydraulic fracture simulators. This is a way of calibrating hydraulic fracture models for improved design/optimization.
