... properties and completion design but with different cluster and stage spacing were analyzed to validate the observed signatures. The conceptual numerical model results show that the wells at wider cluster spacing (and longer stage length) exhibit longer linear flow duration, which does not necessarily...

... for unconventional reservoirs. It uses a simulation model of the reservoir and has been applied to transient linear flow, the predominant flow regime of unconventional wells. The transient linear flow IPR resulted in curves with shapes that are very different from the conventional IPRs. These unexpected shapes were...

For multiple case studies in different shale plays across North America, we show that the end of linear flow period through areas with enhanced...

... transient may extend to many hours or days, or may never appear. This paper introduces a new model showing that miscible fluid injection produces a linear flow response in the early BC DFIT falloff transient that is easily recognized on a Bourdet log-log diagnostic plot as a pressure derivative trend with 1...

... is an extension of the work presented in URTeC paper #2856750, 2018, where a decline curve reproducing the standard transition from linear flow to pseudo steady state flow regimes was proposed for fractured horizontal wells in unconventional reservoirs. In this new work, the formulation was generalized...

... Abstract The dominant transient flow regime for multi-fractured horizontal wells producing from low-permeability and shale (unconventional) reservoirs has historically been interpreted to be transient linear flow (TLF) in the framework of classical diffusion (CD). Recently, observed...

.... On close examination, it was found that both the linear flow regimes and changes in fracture conductivity with time follow a power-law function. Thus, the reason for successful application of Arps Hyperbolic, Power-Law Exponential (PLE), Stretched-Exponential Decline (SEPD) and Duong methods rest...

... Arps hyperbolic model is re-cast in terms of the colloquially named "linear flow parameter", relating the initial rate and initial decline parameters with a functional relationship. Computation of initial rate can be performed from a diagnostic fit of a ½-slope trend line that corresponds to transient...

... Abstract The idea of radius of investigation has been used in conventional pressure transient analysis for various applications such as calculation of distance to a flow barrier. In multistage fractured horizontal wells reservoirs, linear flow predominates for most of the production period...
