Plug&Perf technology in directional wells
Plug&Perf technology in directional wells
Directional boreholes Plug&Perf technology has proven itself not only in horizontal, but also in directional wells
Plug&Perf technology is not just another hydraulic fracturing method. This is a demonstration of the technological sovereignty and operational superiority that we have achieved.
