Evaluation of injection test data from a Baca well

Injection test data from Baca well B-20 show that half of the fluid enters a fractured zone below approx. 5000 ft whereas the primary production zone is at approx. 4000 ft. The fracture created during the subsequent stimulation of B-20 apparently intersects the lower fluid-accepting zone rather than a production zone. Fracture stimulation must provide a channel to a productive region of the natural fracture system to be effective.
