Acidizing/stimulation

Visualization of Acid Treatments With 3D Nuclear-Magnetic-Resonance Imaging

Core-flow tests are usually conducted to test and model stimulation treatments at laboratory scale, to predict the performance of such treatments in carbonate reservoirs.

Core-flow tests are usually conducted to test and model stimulation treatments at laboratory scale, to predict the performance of such treatments in carbonate reservoirs. The visualization of wormholes created within core-flow tests requires novel technologies for evaluation and pathway-prediction purposes. Unfortunately, past visualization techniques were always associated with the destruction of the core sample. This paper describes the use of nuclear-magnetic-resonance imaging (NMRI) as a nondestructive visualization method in correlation with 3D rock imaging.

Introduction

The experiments described in the complete paper were conducted with different core samples such as Indiana limestone, Silurian dolomite, Winterset limestone, and carbonate outcrops.
