A vertical stage completion was in a tight carbonate with average porosity ~ 3%. The reservoir is ~ 950 ft. thick, with varying intervals of porosity ranging from 1-7%. Based on the Microlog response, there were intervals with fracturing indicated, mostly in stage 3. Low porosity carbonate reservoir can be difficult to breakdown and hydraulically fracture. The key to production is to connect the wellbore to the natural fracture network.
Prior to the frac job, Allied Horizontal, perforated the well with CoFrac® System. The initial oil production on this well (170 bopd) exceeded customer expectations and is much better than offset wells.
