Laboratory experiments on blockage removing and stimulation of CBM reservoirs by composite pulsating hydraulic fracturing of radial horizontal wells

Natural Gas Industry B, 2019
It is a common phenomenon during CBM drilling and production that reservoir damage is not eliminated completely. In view of this, a technical idea of composite pulsating hydraulic fracturing of radial horizontal wells which is conducive to blockage ...

Investigation into Influences of Hydraulic Fracturing for Hard Rock Weakening in Underground Mines

Applied Sciences
The long overhanging distance of hard roofs and long-collapse steps induces a large area of suspension on the working face in underground coal mines, resulting in excessive pressure and deformation on the surrounding rocks of the adjacent roadway in the ...
