The Operator of this reservoir had assumed an Archie saturation exponent of n = 2.0, for reserves estimates. The above special core laboratory analysis (SCAL) restored net overburden resistively index, I, vs water saturation, Sw, measurements returned a mean Archie saturation index of n = 1.536. Recomputing the Stock-Tank Original Oil In Place (STOOIP) with the new n value increased the initial reserves estimate by over 30 %. This recompilation not only increased the value of the reservoir but also increased the maximum daily allowable production rate. |
