Post DST Well Test Analysis


Project Completed

Post DST Well Test Analysis

OPC recently assisted an IOC with their offshore West Africa Appraisal well DST Interpretation. 

By combing both PTA and PLT techniques OPC’s Well Test Experts demonstrated to the operator that the data obtained should not be interpreted using simple homogeneous PTA models but rather as layered with distinct layer permeability and geometry. OPC’s PTA analysis has greatly aided the client with their reservoir simulation description and modelling.

OPC also used ConvEx (Pressure Rate Deconvolution) to extract a larger minimum connected volume than otherwise seen by a single build.
