Mar 18, 1980

Appl. No.:

6/131328

Inventors:

James M. Lucas - Houston TX
Alphonse C. Perricone - Houston TX
Dorothy P. Enright - Houston TX

Assignee:

Milchem Incorporated - Houston TX

International Classification:

C08L 3302

US Classification:

260 296TA

Abstract:

The invention relates to an aqueous solution of a filtration control agent for utilization in said aqueous drilling fluid, useful in a method of forming a filter cake on the wall of a well for the reduction of filtrate from said drilling fluid, which is effective at high temperatures and pressures, the terpolymer consisting essentially of: (1) an alkali metal acrylate units; (2) hydroxyalkyl acrylate units; and (3) acrylamide.

Filed:

May 23, 1991

Appl. No.:

7/704823

Inventors:

James E. Lucas - Tomball TX

International Classification:

E02B 1504

US Classification:

210776

Abstract:

An improvement in efficiency of marine type oil spill clean up is achieved by using slideable fastners and support legs extending from a floatable unit to hold a skimmer unit in a relatively fixed horizontal position while using retractable cables with a hydraulic tensioning means to maintain the skimmer in a nearly constant relationship to the wave surfaces.

Filed:

Sep 1, 1977

Appl. No.:

5/829618

Inventors:

James M. Lucas - Houston TX
James Teng - St. Louis County MO

Assignee:

Anheuser-Busch, Incorporated - St. Louis MO

International Classification:

C08L 118
C08L 132

US Classification:

106178

Abstract:

An overprint lacquer comprising a solvent, a resin, a plasticizer, and a gelling agent. The gelling agent is hydroxypropylcellulose acetate. The coatings of this gel-containing lacquer show improved adhesive characteristics and improved durability when compared with conventional overprint lacquers that have higher nitrocellulose content. Also, the viscosity of the lacquer is more readily controllable due to the presence of the gelling agent.

Dorothy P. Enright - Houston TX

Assignee:

Milchem Incorporated - Houston TX

International Classification:

C08F 2238

US Classification:

526240

Abstract:

The invention relates to an aqueous drilling fluid composition, a filtration control agent for utilization in said aqueous drilling fluid, and a method of forming a filter cake on the wall of a well for the reduction of filtrate from said drilling fluid, which are effective at high temperatures and pressures, by utilization of a terpolymer of: (1) a monovalent alkali metal salt of acrylic acid; (2) an hydroxy alkyl acrylate; and (3) acrylamide.

US Patent:

Filed:

Mar 15, 1984

Appl. No.:

6/590029

Inventors:

James M. Lucas - Houston TX

Assignee:

Milchem Incorporated - Houston TX

International Classification:

C09K 702

US Classification:

252 85C

Abstract:

The invention relates to an aqueous drilling fluid composition, a filtration control agent for utilization in said aqueous drilling fluid, and a method of forming a filter cake on the wall of a well for the reduction of filtrate from said drilling fluid, by utilization of a copolymer of: (1) a (meth) acrylamido alkyl sulfonic acid or alkali metal salt thereof; and (2) N, N-dialkyl (meth) acrylamide. The copolymer may be cross-linked with N,N'-methylenebisacrylamide or other appropriate cross-linking agent.

Appl. No.:

6/057918

Inventors:

Assignee:

Milchem Incorporated - Houston TX

International Classification:

C08F 200
C08F 430

US Classification:

526229

Abstract:

A continuous process is provided for producing substantially homogeneous, non-tacky solid terpolymers of acrylamide, an alkali metal salt of acrylic acid and a hydroxyalkyl acrylate, and copolymers, optionally cross-linked, of a (meth)acrylamidoalkylsulfonic acid or alkali metal salt thereof and (meth)acrylamide or N-alkyl(meth)acrylamide, by rapidly heating a single phase high solids aqueous solution of the monomers to polymerization initiation temperature immediately prior to depositing a uniform layer of the solution and, at the same time, a solution of a polymerization initiator, onto a moving surface, the surface and the reaction mixture only being heated if necessary to keep the temperature of the polymerizing mixing from dropping substantially below the polymerization initiation temperature.
