... for further treatment fluid leakoff into fractures and rock wettability alteration by surfactant has been proposed previously. Recent residual surfactant analysis in produced water from both parent and child wells indicates that there is indeed hydraulic communication after frac hits, and field trials...

... Abstract Production interference between parent and infill wells has become of utmost importance in unconventional reservoirs across the U.S. due to sub-par production performance of child wells as well as possible loss of production to the parent well. To mitigate production interference...

..., is critical for planning infill well. Parent well depletion results in potential negative impact including: – Asymmetric fracture propagation from the child well into the depleted area around the parent well – Potential detrimental fracturing hits to the parent well These effects would...

... placing infill child wells. But after drilling and completion, post-stimulation flowback is also critical in maintaining well productivity and performance. To optimize field management strategy, a comprehensive understanding of the impact of production induced geomechanical property changes on infill well...

... Abstract Fracture stimulation of infield or offset wells in unconventional developments can involve communication between the legacy (parent) wells and newly drilled offset (child) wells. Production from the legacy well results in a decrease in reservoir pressure and stress, which can cause...
