  • Patent number: 10023498
    Abstract: Compositions and methods for terminating water flow in a subterranean formation are described. The compositions include a calcium aluminate cement, a Portland cement, a non-aqueous carrier fluid, and a polyphosphate. The cement compositions, upon making contact with water, form a viscous gel that sets into a hardened mass with extraordinary compressive strengths in a short period of time.

  • Patent number: 9869156
    Abstract: 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.

  • Patent number: 8459352
    Abstract: Selective placement of conformance treatments in multi-zone well completions. A method includes injecting a relative permeability modifier into a zone and optimizing a ratio of desired fluid to undesired fluid produced from the zone, including adjusting at least one flow control device between fully open and fully closed configurations. Another method includes injecting a relative permeability modifier into multiple zones, one at a time, via respective flow control devices, and then producing fluid from each of the zones. Another method includes identifying which of the zones to treat by, for each of the zones: a) closing flow control devices corresponding to the other zones, and b) evaluating fluid produced from the zone; and injecting a conformance treatment into the zones identified as the zones to treat.

  • Patent number: 7182136
    Abstract: 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.
