Creation and characterization of horizontal hydraulic fractures in oil shale

Sandia Laboratories, in support of the Department of Energy Laramie Energy Technology Center's in-situ oil shale programs, conducted a true in-situ oil shale experiment to evaluate the porosity and permeability produced by detonating a slurry explosive in one or more previously formed hydraulic fractures. The experiment involved the creation and characterization of three closely spaced horizontal hydraulic fractures, followed by the insertion and detonation of a slurry explosive in two of these fractures. Initial site evaluation, explosive evaluation tests, and numerical analyses provided guidance to the hydrofracturing procedure. Numerous diagnostic and evaluation measurements were made before, during, and after the hydrofracturing process for evaluation of the fractures. The results showed that three closely spaced fractures satisfactory for subsequent explosive fracturing had been created in essentially horizontal planes.
