CHALLENGE:
An operator for JV Partnership on one of Shell’s Gulf of Mexico (GoM) deepwater projects / fields was reluctant to stimulate a well with 25-30% water cut for fear of increasing produced water volumes and /or the well’s water cut. Well had low productivity (low PI) and apparent damage (high skin).
SOLUTION:
The operator was presented with a list of GoM wells that had similar water cut behavior to the well in question that were successfully stimulated without a corresponding increase in water cut. We created a StimCADE model that showed the 70-quality foam diverter effectively working to stimulate the damaged zones. We also used Prosper / GAP to show increased productivity and optimum manifold alignment post acid treatment.
After presenting the data, the partner agreed to get the well treated. Following the mud acid treatment, the well’s watercut dropped from 32% to 0%. The PI increased from 2 blpd/psi to 14 blpd/psi and the skin dropped from 45 units to 8 units.
TECHNOLOGIES IMPLEMENTED:
• Spotfire
• StimCADE
• Prosper / GAP
