Pressure-Pressure Convolution Analysis Using Wireline Formation Tester Data

摘要

When flow rate data are not reli-able,the need for flow rate to esti-mate permeability from wireline formation tester multiprobe and packer/prode pressure data sets can be eliminated by use of pressure-pressure (p-p) convolution.The P-P convolution uses two pressure data rets recorded at different spatial locatons,thus enabling parameter estimation without flow rate.This paper compares multiprobe and packer/probe pressure stansient tests by considering various P-P convolution options.
