This paper describes the testing of a novel concept based on resistivity measurements to monitor acid-stimulation operations. It is believed that the proposed concept for monitoring the wormholing process can be adopted in the field with the deployment of induction tools. The outcome of this novel monitoring concept is expected to provide an unprecedented level of understanding of the depth, number, and type of wormholes being created downhole.

Introduction

Induction-logging tools can be viewed as an attractive option for characterizing wormhole morphology resulting from the acidizing process and can be used to assess acid-stimulation operations. The authors propose to extend the use of ­resistivity-logging tools for evaluating acid-stimulation jobs after well cleanup.
