Patent EA-010933-B1 (EA)
Title: Well treatment composition crosslinkers and uses thereof
Inventor: DESSINGES MARIE NOEL
IPC: E21B43/22
Filed: 2006-01-12
Abstract: This invention relates to compositions used in treating subterranean formations, which include a hydrated polymer, and a dry blended multi-functional component. The hydrated polymer and dry blended multi-functional component are mixed at the ground surface of a wellsite, and subsequently injected into the formation providing controlled delay in crosslinking to achieve targeted fluid viscosity properties. The hydrated polymer may be a guar, hydroxypropyl guar, carboxymethyl guar, carboxymethylhydroxypropyl guar, synthetic polymers, and guar-containing compounds. The dry blended multi-functional component may include a crosslinker and a chelating agent, and the well treatment fluid may further include an activator mixed with the hydratable polymer. The chelating agent may be a polyols, gluconate, sorbitol, mannitol, carbonate, or any mixtures thereof. The crosslinker may be any source of boron, alkaline earth metal borates, alkali metal borates, zirconium compounds, titanium compounds, or any combination thereof, while the activator may be a caustic soda or magnesium oxide compound. The invention further provides methods for producing a well treatment composition including providing a hydrated polymer, and providing a dry blended multi-functional component. Also, methods of hydraulically fracturing a subterranean formation, as well as cleanup operations and gravel packing a wellbore are provided as well.
Patent EA-007695-B1 (EA)
Title: Piston pump
Inventor: WINIGER GERHARD
IPC: F04B7/00
Filed: 2004-06-01
Abstract: The invention relates to a piston pump whose piston (4), via its upper and lower piston faces, delimits the working space inside the pump cylinder (5) on both sides. The working space (c) is joined via a lever system (19, 22, 25, 28, 31) to two force-guided inlet valves (14, 16) and two force-guided outlet valves (10, 12) that each alternately open and close for filling or discharging the working volume upon reaching both final positions of the piston. An additional working volume, which is reduced by the volume portion of the piston rod, is obtained by the piston being acted upon twice per working stroke as described by the invention thus nearly doubling the efficiency and resulting in a delivery flow with few pulsations. A small residual pulsation remains only from the short period of time during which the valves change from open to closed upon reaching both end positions of the piston inside the cylinder. According to the invention, the design of the piston pump makes it possible for two or more piston pumps to be synchronously operated by coupling their drive levers (31, 40) to a common piston rod (35) and that, in doing this, different stroke lengths can be set by modifying the lever ratios.
