Unconventional Testing Alternatives

Formation Leak-off Tests are a simple, effective, economical #welltest strategy for #AER Initial Pressure compliance in oil and gas (#LNG) wells. After landing a horizontal multi-stage frac’ string, run recorders, open (burst) the toe hydro-port, and monitor the pressure leak-off or fall-off feed into the reservoir. Pressure Transient Analysis (PITA) is employed to extrapolate a reservoir pressure (p*). What’s not specifically clear in AER D40 is that Pressure Transient Analysis (#PTA) is an acceptable method for estimating Initial Pressure Oil and Initial Pressure Gas conditions.
