Paper presented at the SPE Unconventional Resources Conference, April 1–3, 2014
Paper Number: SPE-168966-MS
... Abstract Handling flow through fractured media is critical for transient pressure and flow analysis in shale gas reservoirs, because gas production from such low-permeability formations relies on fractures, from hydraulic fractures and fracture network to various-scaled natural fractures, to...

Paper Number: SPE-168982-MS
... Abstract Although existing models for analysing single-phase flowback water production at the onset of flowback in tight oil and gas reservoirs provide estimates of fracture volume, they are not applicable to shale gas reservoirs. This is because flowback data from shale gas wells do not show...
