Abstract
Official abstract text for this publication.
Methods of treating subterranean formations comprising providing a wellbore in a subterranean formation having at least one fracture therein; providing a first treatment fluid comprising a base fluid and an acid generating inert agent; providing a second treatment fluid comprising a base fluid, and an acid generating activator; introducing the first treatment fluid into the at least one fracture; and introducing the second treatment fluid into the at least one fracture, wherein the acid generating inert agent in the first treatment fluid reacts with the acid generating activator in the second treatment fluid so as to generate an acid in the at least one fracture and create or enhance at least one microfracture therein.
First claim
Opening claim text (preview).
The invention claimed is: 1. A method comprising: providing a wellbore in a subterranean formation having at least one fracture therein; providing a first treatment fluid comprising a base fluid and an acid generating inert agent in an amount of from about 0.1% to about 50% by volume of the first treatment fluid, wherein the acid generating inert agent is selected from the group consisting of a sulfonate ester selected from the group consisting of a methyl p-toluenesulfonate, a…
