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...

Our proposed approach is based on a high frequency asymptotic solution of the diffusivity equation in heterogeneous reservoirs and serves as a bridge between simplified analytical tools and complex...

In this paper we argue that slow slip on numerous fault planes is occurring in shale gas reservoirs during stimulation. In fact, we believe this is likely to be the dominant deformation mechanism during hydraulic...

...) ( Arthur et al. 2008 ; Jenkins and Boyer 2008 ). Geological formations of tight and shale gas reservoirs exhibit extremely low permeability within which gas is trapped ( Hill and Nelson 2000 ), and accordingly hydraulic fracturing is performed in order to enhance permeability and increase production rate...
