摘要
Diagnostic or assisting lateral wellbores can have a significant benefit for injecting and distributing treatment fluids and other materials within complex fracture networks that surpass conventional injection at the primary lateral wellbore perforations for acquiring empirical knowledge about the numerous processes that influence shale reservoir production which occur after primary shale reservoir stimulation. Injection of diagnostic treatment fluids or treating chemicals for understanding production optimization, such as water-block removal, fines migration removal, and treating chemicals for prevention of scale and paraffin deposition, can be injected along the diagnostic lateral wellbore or frac interval lateral wellbores to give broader and/or deeper distribution into the fracture network than by using mono-bore-centric diagnostic injection techniques. Diagnostic lateral treatment techniques can also improve fluid or chemical distribution, such as the use of gas injection to help energize fluid flow to the primary lateral during production optimization treatments, including reverse diversion methodology.
