Abstract: A controlled rate of propagation of the fluid saturation front or thermal front is desired in may oil and gas and geothermal operations. Natural fractures and fractures created during hydraulic stimulation may have heterogeneous hydraulic properties resulting in uneven flow distributions, therefore leading to short-circuiting and breakthrough issues. The present invention relates to wellbores connected hydraulically by multiple fracture zones; methods are directed to control for even flow distribution among fractures, regardless of heterogeneities in fracture hydraulic properties, and to control propagation of saturation fronts and thermal fronts in subsurface reservoirs.

Abstract: A fluid-driven multi-mode extended reach vibration tool is selectively operable to control generating shock waves of different amplitudes by a downhole motor or shock-wave generating tool. Interrupting and then reinstating flow of pressurized fluid through the tool enables switching between different shock wave amplitudes, as such causes rotation of a slot piston to successive positions and enables it to unblock designated fluid ejection paths, while blocking others. Blocking different flow paths and unblocking others allows generating different internal pressures and shock wave amplitudes under the externally-applied fluid pressure downhole. There is also an “off” mode with no vibration, while maintaining well control and fluid pressure at the BHA.
