Assignee:

Tetra Technologies, Inc.

International Classification:

E04B001/74

US Classification:

252/062000

Abstract:

A thermally insulating fluid composition comprising a glycol solvent for a viscosifier, a viscosifier, and optionally, an aqueous brine. The glycol may be selected from a propylene glycol, or under excessive heat temperatures, a butylene glycol, which can be used with or without a viscosifier. Viscosifiers can be selected from hydroxy propyl methyl cellulose, xanthan and hydroxy propyl guar and combinations thereof. In one method of producing the thermally insulating composition, a viscosifier is added to an aqueous brine, water is then added to that solution followed by the addition of dry salt of the brine to increase density if necessary. A propylene glycol solvent is added to the resulting solution. The thermally insulating fluid composition insulates substances stored or transported in multi-walled vessels, tanks, piping and thermal units. A method of applying the insulating fluid composition of this invention comprising the steps of injecting the thermally insulating fluid into the cavity formed by two adjacent walls of the vessel or piping and then sealing off the opening.

Assignee:

Halliburton Company - Duncan OK

International Classification:

C04B 1904

US Classification:

106 74

Abstract:

Rapidly dissolvable powdered silicates having a molar ratio of silicon dioxide to alkali metal oxide in the range of from about 1. 5:1 to about 3. 3:1 wherein the alkali metal is selected from the group consisting of sodium, potassium and mixtures thereof. Methods of using the powdered silicates and resulting solutions in connection with sealing and cementing, especially of well formations, are provided.

Halliburton Company - Duncan OK

International Classification:

E21B 4327

US Classification:

252 855C

Abstract:

A method and composition to dissolve siliceous material in a subterranean formation. The composition of the invention is an aqueous acidic solution having a pH no greater than 2 and comprised of at least one mineral acid and a fluoride compound of zirconium, chromium or cobalt. The method is carried out by contacting the siliceous material in the subterranean formation with the above identified composition.

International Classification:

E21B 33138
E21B 3600

US Classification:

166288

Abstract:

The present invention provides a method of consolidating an incompetent subterrnean formation. An acid curable resin consolidating fluid is positioned within casing in a wellbore in the vicinity of perforations through the casing. A gas generating charge positioned within the casing then is ignited to generate gas pressure which rapidly forces the consolidating fluid through the perforations and into the subterranean formation while substantially simultaneously catalyzing the resin composition. The consolidating fluid is caused to rapidly harden to consolidate the formation in the vicinity of the perforation without any significant permeability loss.

US Classification:

523131

Abstract:

Methods of continuously forming and suspending consolidatable resin composition coated particulate material in a gelled aqueous carrier liquid and transporting the coated particulate material by way of the gelled aqueous carrier liquid to a zone in which the sand is consolidated. In accordance with the methods, substantially continuous streams of a gelled aqueous carrier liquid, uncoated particulate material, a resin composition which will subsequently harden and a surface active agent are admixed whereby the particulate material is continuously coated with the resin composition and suspended in the gelled aqueous carrier liquid.

US Classification:

166276

Abstract:

Methods of consolidating incompetent subterranean formations are provided whereby aqueous treating solutions are utilized to condition the formation, to carry a hardenable organic consolidating fluid into the formation and/or to carry particulated solids coated with a hardenable organic consolidating fluid into the formation and to cause the organic consolidating fluid to harden whereby a hard permeable mass is formed in the formation which prevents the undesirable movement of loose or incompetent sands therein.
