Challenge: Improve oil production—but avoid water production—from mature wells in a tight sandstone formation with weak or thin barriers to nearby water zones.
Solution: Minimize out-of-zone fracture growth and permeability near the water zone by designing two stimulation operations: Combine the BroadBand Shield fracture-geometry control service with either conventional fracturing designs or the HiWAY flow-channel fracturing technique.
Results:
- Improved oil production by 300% to >3,000%
- Reduced or minimally increased water cut, even in the riskiest well
