Minifrac Nolte ACA Radial Time

There is one Minifrac Nolte After-Closure Analysis (ACA) radial time function, FR1.

It has a minimum value of 0.0 (at late time) representing an infinite shut-in time. P* is the extrapolation of the radial line to FR = 0, which corresponds to an infinite shut-in time.

FR1 is the time function described in Minifrac Reference 1 as:
