摘要： The present invention provides a method of controlling fluid loss to a permeable formation penetrated by a wellbore. A novel fluid loss agent is prepared by forming a crosslinked polymer gel which then is sheared to break the gel into discrete particles of a particular size range. A slurry then is formed of the particles by dispersing the particles in an aqueous fluid having a density similar to that of the gel particles. The slurry then is introduced into contact with the permeable formation and a filter cake of the particles is formed upon contact with the formation and loss of the slurrying fluid to the formation. The filter cake provides further fluid loss control to the permeable formation.

摘要： The present invention provides methods of stimulating fluid production while preventing the migration of sand with produced fluids from an unconsolidated subterranean formation penetrated by a well bore. The methods basically comprise the steps of creating one or more fractures in the formation, injecting a hardenable resin composition into a portion of the formation through which the fractures extend whereby the portion of the formation is consolidated into a hard permeable mass and depositing proppant in the fractures to maintain the fractures open.

摘要： A method of preparing high density particulate slurries is provided whereby slurries containing in excess of 23 pounds of particulate per gallon of fluid can be introduced into a subterranean formation. In accordance with the method, a viscosified pad fluid is introduced into a wellbore to create a filter cake in a desired zone within a subterranean formation. The high density slurry then is introduced into the formation to substantially fill any annular space present without significant settling. This permits the coating of the entire exterior surface of highly deviated casing exposed within a wellbore.

摘要： The present invention provides improved methods of placing proppant in fractures formed in a subterranean zone to prevent the subsequent flow-back of the proppant with fluids produced from the zone. The methods are basically comprised of the steps of depositing a mixture of hardenable resin composition coated proppant and uncoated proppant in the fractures and then causing the resin composition to harden into stationary permeable masses in the fractures.

摘要： Methods for enhancing the conductivity of propped fractures in subterranean formations may involve using a tackifier to minimize particulate settling during particulate placement operations in subterranean formations. For example, methods may involve introducing a first treatment fluid into a wellbore extending into a subterranean formation at a pressure sufficient to create or extend at least one fracture in the subterranean formation; and introducing a second treatment fluid into the wellbore at a pressure sufficient to maintain or extend the fracture in the subterranean formation. The first treatment fluid may include at least a first aqueous base fluid and a tackifier. The second treatment fluid may include at least a second aqueous base fluid and a proppant particle.
