Abstract: A method for well treatment by forming a temporary plug in a fracture, a perforation, a wellbore, or more than one of these locations, in a well penetrating a subterranean formation is provided, in which the method of well treatment includes: injecting a slurry comprising a degradable material, allowing the degradable material to form a plug in a perforation, a fracture, or a wellbore in a well penetrating a formation; performing a downhole operation; and allowing the degradable material to degrade after a selected time such that the plug disappears.

Abstract: In downhole treatments in the oilfield, ball sealers seated in perforations may not fully seal and may leak fluid through gaps and asperities between the balls and the perforations. A method is given for improving the sealing of ball sealers in perforations by adding a sealing agent that forms a plug in the gaps and severely restricts or eliminates fluid flow. The sealing agent is preferably degradable or soluble, malleable fibers slightly larger than the gaps. Optionally, the particles may be non-degradable, rigid, of different shapes, and smaller than the gaps but able to bridge them. Mixtures of sealing agents may be used. The sealing agent may be added with the ball sealers, after the ball sealers, or both.

Abstract: A system and method for completing a well with multiple zones of production is provided, including a casing having a plurality of valves integrated therein for isolating each well zone, establishing communication between each underlying formation and the interior of the casing, delivering a treatment fluid to each of the multiple well zones, and filtering produced fluids from each underlying formation.

Abstract: The invention provides an oilfield suspending friction reducer treatment composition fluid comprising from about 0.001 weight percent to about 0.5 weight percent of a drag reducing surfactant; at least one drag reducing enhancer selected from the group consisting of polymeric drag reduction enhancers, monomeric drag reduction enhancers, and mixtures thereof.

Abstract: A method well treatment includes establishing fluid connectivity between a wellbore and at least one target zone for treatment within a subterranean formation, which is intersected by a wellbore. The method includes deploying coiled tubing into the wellbore and introducing a treatment composition into the wellbore. The method includes contacting a target zone within the subterranean formation with the treatment composition, introducing a diversion agent through the coiled tubing to an interval within a wellbore and repeating the introduction of the treatment, the contacting of the target zone and the introduction of the diversion agent for more than one target zone.
