Feb 11, 1987

Appl. No.:

7/013462

Inventors:

Ronald K. Robinson - Norwalk CA

International Classification:

B22D 1710

US Classification:

164113

Abstract:

A process is disclosed for die-casting aluminum alloy A365. 2, or like alloys having high aluminum and low iron content, which have hitherto not been formed into parts in die-casting processes because of undesirable soldering of the cast part to the steel die. In the disclosed process the molten aluminum alloy containing a maximum of 0. 12 percent iron and at least 90 percent aluminum is injected under pressure into a die through a gate at an injection rate which is approximately 55 to 93 cubic inch per second. When the rate of injection of the aluminum alloy into the die is in this range, there is no sticking or soldering of the die-cast part to the steel walls of the die.

International Classification:

C09K 8/588
C09K 8/584
E21B 43/20

Abstract:

Provided herein are liquid polymer (LP) compositions comprising a synthetic (co)polymer (e.g., an acrylamide (co)polymer), as well as methods for preparing inverted polymer solutions by inverting these LP compositions in an aqueous fluid. The resulting inverted polymer solutions can have a concentration of a synthetic (co)polymer (e.g., an acrylamide (co)polymer) of from 50 to 15,000 ppm, and a filter ratio of 1.5 or less at 15 psi using a 1.2 μm filter. Also provided are methods of using these inverted polymer solutions in oil and gas operations, including enhanced oil recovery.
