Average reservoir pressure value along the boundary of drainage area
p_e = \frac{1}{L_e} \int_0^{L_e} p(x,y,z) dl |
where is the boundary of drainage area
This definition is based on the idea that there is a boundary line which restricts radial flow around a well, which is a fair assumption in most practical cases.
The advantage of this method over is that:
Petroleum Industry / Upstream / Production / Subsurface Production / Well & Reservoir Management / Formation pressure (Pe)
Subsurface E&P Disciplines / Production Technology
[Reservoir pressure] [Initial formation pressure, Pi] [Drilled formation pressure, Pd] [Startup formation pressure, P0] [ Multiphase formation pressure ]
