Many of the more recent wells at Ekofisk field in the Norwegian North Sea have been completed as monobores, with lengthy horizontal or high-angle sections and several distinct perforation clusters, with as many as 20 separate zones. Early methods of stimulating these chalk reservoirs involved high-volume acid jobs, requiring bullheading, and the use of frac balls to divert flow to less-permeable sections. However, after collection and evaluation of much data, it became clear that many of the perforated intervals were unproductive. To address this situation, it was decided to change to a selective stimulation method, using newly designed coiled tubing (CT)-deployed straddle pack-off tools.
