International Classification:

C09K 700

US Classification:

507200, 507100, 507103, 507203, 507902, 507922, 507925, 507933, 507939, 166300, 1663051, 166308

Abstract:

The effect of various chemical or biological agents in well treatment fluids can be delayed by sequestering the agents in the discontinuous phase of an emulsion for a period of time, before the emulsion is destabilized by exposure to at least one of: (1) a change in temperature, (2) a change in pH, (3) a change in salinity, (4) a change in alcohol concentration, (5) a change in stabilizing surfactant concentration, (6) a change in organic ion concentration, (7) a change in destabilizing surfactant concentration, (8) a change in surfactant adsorbent material concentration, (9) an ultrasonic pulse, and (10) an electrical field. Upon exposure to the emulsion destabilizing condition, the agent sequestered in the discontinuous phase of the emulsion is released into the continuous phase of the fluid composition, where it can have its intended effect.

Appl. No.:

11/285440

Inventors:

Michael D. Parris - Richmond TX, US
Ismail El Kholy - Sugar Land TX, US

Assignee:

Schlumberger Technology Corporation - Sugar Land TX

International Classification:

E21B 43/26

US Classification:

1663085

Abstract:

In the presence of certain polyols, a guar gum or similar polysaccharide thickener solution is boron crosslinked before achievement of complete hydration of the thickener, without compromising the viscosity level achieved in a fracturing fluid by the time it is pumped into the wellbore and fractures the subterranean formation adjacent the wellbore. Methods continuously involve hydrating a polysaccharide thickener to an extent of 10% to 75%, but less than full hydration. Before 75% hydration is exceeded, a boron crosslinker is added. Upon addition of the boron crosslinker, the fluid is injected into the wellbore to stimulate hydrocarbon production. Because less time is needed for hydration, well site mixing equipment is down-sized smaller to achieve better efficiency and cost savings.

Abstract:

Methods comprising preparing an aqueous mixture of an anionic polymer, a charge screening surfactant, and a borate crosslinker, wherein the mixture has a conductivity less than 10 mS/cm, injecting the mixture down a wellbore, and gelling the mixture. An embodiment of the aqueous mixture can also include tetramethylammonium chloride as a clay stabilizer and a metal crosslinker such as a complex of zirconium and an amino acid ligand system. An embodiment can effectively provide borate crosslinking of an anionic polymer in a low-ionic-strength fluid system, without sacrificing ultimate gel strength or thermal persistence of the metal crosslinked polymer.

US Classification:

507261, 507266, 507269, 507273

Abstract:

A delayed crosslinker system useful in downhole treatment fluids is disclosed. The crosslinker system comprises water-reactive solids, a non-aqueous, non-oily, hygroscopic liquid, a suspension aid, and an optional polyol. The crosslinker system may be prepared at a remote location and transported to the site of its intended use. There it may be pumped into a formation and activated when a gel fluid is introduced into the wellbore, only then forming a high viscosity treatment fluid. Thus, the amount of energy required for pumping is reduced. The optional polyol component increases crosslink delay and enhances the rate of viscosity after high shear (shear recovery).

Abstract:

A method of treating a subterranean formation penetrated by a wellbore utilizes a treating fluid formed from an aqueous solution of a water-soluble polymer. The treating fluid further contains a crosslinking agent and an optional delayed release alkaline additive. The delayed release alkaline additive may be at least one of urea, a urea derivative, a solid alkaline earth metal carbonate, a solid alkaline earth metal oxide and combinations of these. The treating fluid further includes an acidic pH adjusting agent used in an amount to provide the treating fluid with a pH of less than about 5. The treating fluid is then introduced into the formation.
