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.
