... value [original fluid in place (OFIP)] during BDF. Although CFIP calculations do not assume a flow geometry, the SLA method requires this to extract reservoir/fracture information. Herein, transient linear flow (TLF) is assumed and used for the SLA‐method derivation, which allows the linearflow...

The solutions are developed for transient linear flow, which is a dominant‐flow regime in many tight/shale reservoirs. In addition...
