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:
- it provides more accurate estimate of the pressure away from a given well
- is not dependent on convention, which may be not valid for a given well
