Filed:

Dec 28, 1990

Appl. No.:

7/635672

Inventors:

Ben W. Wiseman - Midland TX
Leroy L. Carney - Houston TX

International Classification:

E21B 4327
E21B 4102

US Classification:

166307

Abstract:

A method of stimulating production from an oil or gas well comprising the steps of (a) injecting a desiccant through the well bore to dehydrate the well bore and a production zone within several feet around the well bore, (b) injecting an anhydrous acid into the production strata, the anhydrous acid being formulated to be gaseous at bottom hole temperature and pressure so that the gaseous anhydrous acid permeates through the dehydrated production strata and dissolves in connate water to form an acidic solution, and (c) shutting in the well for a period to allow the acidic solution formed in situ to react with the materials of the formation thereby increasing the permeability of the production strata and stimulating production from the well. A alcohol/polyglycol desiccant with exceptional lubricating, heat stability, and corrosion inhibiting characteristics is used to dehydrate the well and to form a corrosion resistant film on surfaces of the production string and casing.

Filed:

Jun 1, 1976

Appl. No.:

5/691736

Inventors:

Leroy L. Carney - New Caney TX

Assignee:

Halliburton Company - Duncan OK

International Classification:

C09K 702

US Classification:

252 85C

Abstract:

The friction created by rotating and reciprocating a drill pipe in a well penetrating a subterranean formation is reduced by including an ester of an oxazolidine derivative in an aqueous drilling fluid or a mixture of said ester and certain alcohols. This ester of an oxazolidine derivative is represented by the following general formula: ##STR1## wherein n is a whole integer within the range of about 5 to 20.
