Abstract
Official abstract text for this publication.
The subject disclosure relates to matrix acidizing. More specifically, systems and methods are described for estimating a diffusion coefficient for an acid fluid used to stimulate a subterranean reservoir wherein a spent acid is formulated that includes one or more by-products of the reaction between the fluid and rock. A rock sample, such as in the form of a rotating disk is exposed to spent acid under elevated pressure and temperature conditions while the fluid is sampled and analyzed. A diffusion coefficient for the spend acid is estimated.
First claim
Opening claim text (preview).
What is claimed is: 1. A method of estimating a diffusion coefficient for a stimulation fluid used to stimulate a subterranean reservoir rock by at least partially dissolving the rock, the method comprising: generating a partially spent stimulation fluid comprising a stimulation fluid used to stimulate the subterranean reservoir rock and one or more reaction by-products, the reaction by-products being of a type produced during reaction of the stimulation fluid with the reservoir r…
