Patent number: 9869156Abstract: Clay-based retarders may be useful in delaying the gel time of a gellable treatment fluid and, consequently, subterranean operations. For example, a method may involve providing a gellable treatment fluid comprising: an aqueous base fluid; a base polymer comprising an acrylamide monomer unit; a polymeric organic crosslinking agent comprising a crosslinkable polymer selected from the group consisting of polyethyleneimine, polyvinylamine, chitosan, any derivative thereof, any salt thereof, and any combination thereof; and a clay-based gel retarder; introducing the gellable treatment fluid into a wellbore penetrating a subterranean formation; and forming a gel with the gellable treatment fluid in at least a portion of the wellbore, at least a portion of the subterranean formation, or both. In some instances, producing the gellable treatment fluid may involve not pre-hydrating the clay-based gel retarder.Type: GrantFiled: October 22, 2013Date of Patent: January 16, 2018Assignee: Halliburton Energy Services, Inc.Inventors: B.

Patent number: 7182136Abstract: The present invention provides a method of stimulating a subterranean formation penetrated by a well. The formation has a water-bearing section and a hydrocarbon-bearing section. The method includes the steps of: (a) introducing into the formation an aqueous treatment fluid containing a hydrophobically-modified relative permeability modifier, and (b) introducing an acidizing treatment fluid into the formation. The hydrophobically-modified RPM can be formed and introduced into the formation in several ways. For example, the hydrophobically-modified RPM can be the reaction product of a hydrophilic polymer and a hydrophobic compound that are capable of reacting with each other. The hydrophilic polymer is a polymer containing reactive amino groups in the polymer backbone or as pendant groups, which are capable of reacting with a hydrophobic alkyl halide compound.Type: GrantFiled: July 2, 2003Date of Patent: February 27, 2007Assignee: Halliburton Energy Services, Inc.Inventors: Eldon D.
