2PROK-SIAG-1 Stand-alone Two-Packer BHA for Selective Isolation with Hydraulic Disconnection from the Tubing (rated up to 5076 psi)

BHA APPLICATION ALLOWS

• to isolate the leak interval by a well servicing team with minimum costs;
• to turn the well back on after a non-production or shutdown period due to a high water-cut of the product, to put the well back to the stock of producing wells;
• to develop the well drainage area with the maximum possible output of hydrocarbon reserves;
• to decrease the water-cut percentage of the well fluid down to 10-30% and enhance oil production by water-repellent treatment of the bottom-hole formation area (an engineering calculation is needed);
• to avoid expensive remedial works.

ADVANTAGES

• after BHA is set the tubing is disconnected hydraulically without tubing string rotation;
• reliable isolation of the production string leak interval;
• workover activities to replace downhole pumping equipment are carried out without plugging and decreasing the reservoir properties or the formation bottom-hole area;
• attachments: bypass valves create conditions for well production with maximum oil output, equalizing valve and safety assembly enhance the safety during workover and emergency activities.
