Appl. No.:

09/535549

Inventors:

David Dino - Cranbury NJ
Jeffrey Thompson - Hightstown NJ

Assignee:

Elementis Specialties, Inc. - Hightstown NJ

International Classification:

C09K 700

US Classification:

516101, 507100, 507140, 507901, 501146

Abstract:

Conventional organophilic clays, when used as rheological additives in oil based invert muds, display marked viscosity loses in the mud when these muds are heated much above 350Â F. , whereas muds prepared according to the present invention are dramatically more viscosity stable at temperatures through 500Â F. The present invention relates to the discovery of oil based invert emulsion drilling fluids that provides more stable drilling fluid viscosity and anti-settling performance over varying temperatures when compared to conventional fluids containing organoclays. As a result, the inventive fluids of this invention are ideal candidates for high temperature applications. This invention in another aspect of this invention is a process for improving the rheological properties of oil well drilling fluids particularly useful for oil-based invert emulsion types of drilling fluids. The new process uses as a rheological viscosifer for such fluids as a specific organoclay which when added to a drilling fluid at from about 0. 5 and 5% by weight creates an inventive drilling fluid composition less sensitive to the very hot temperatures found in the drilling hole, and in the long stem of drilling pipe.

International Classification:

C23C016/00

US Classification:

427252, 427229

Abstract:

The present invention relates to novel 1,3-diimine copper complexes and the use of 1,3-diimine copper complexes for the deposition of copper on substrates or in or on porous solids in an Atomic Layer Deposition process.

International Classification:

C09K 8/22

US Classification:

507131, 507133, 507244, 507246

Abstract:

The invention is of oil-based drilling fluids including invert emulsion fluids that are able to maintain a relatively consistent rheological profile over a wide temperature range. The invention also includes new additives that enable the preparation of drilling fluids with viscosities that are less affected by temperature over a temperature range from less than about 40 F. to more than about 250 F. compared to conventional fluids. These additives are based on reaction products of polyamines and carboxylic acids with two or more carboxylic moieties combined with alkoxylated amines and fatty acid amides. In addition, this invention permits the use of reduced amounts of organoclay rheological additives in drilling fluids.
