    摘要： Optical analysis systems may be useful in monitoring fluids relating to cementing operations in or near real-time, e.g., for location and/or the status of a cement setting process. For example, method may involve containing a cement slurry within a flow path, the cement slurry having a chemical reaction occurring therein; and optically interacting the cement slurry with an integrated computational element, thereby generating an output signal corresponding to a characteristic of the chemical reaction.

    摘要： Methods and compositions are described for treating water- and hydrocarbon-producing subterranean formations with a relative permeability modifier at concentrations below those conventionally used in the art, while not substantially impacting the treatment fluid's performance. Treatment fluids described herein comprise a base fluid, a relative permeability modifier comprising a hydrophobically modified hydrophilic polymer, and a companion polymer interacting synergistically with the relative permeability modifier such that the treatment fluid is operable to reduce the water permeability or to increase an aqueous fluid injection pressure of at least a portion of a subterranean formation by more than the relative permeability modifier or the companion polymer acting alone at like concentration. The water permeability reduction and/or the aqueous fluid injection pressure increase can be more than additive. Methods described herein comprise placing such treatment fluids in at least a portion of a subterranean formation.

    摘要： A method of servicing a wellbore in contact with a subterranean formation comprising placing a wellbore servicing fluid comprising a polyuronide polymer within the wellbore, contacting the wellbore servicing fluid with a divalent ion source, and allowing the wellbore servicing fluid to form a gel within the wellbore wherein the divalent ion source is located within the wellbore. A method of servicing a wellbore in contact with a subterranean formation comprising (a) placing a wellbore servicing fluid comprising a polyuronide polymer into the wellbore wherein the wellbore servicing fluid contacts a calcium ion source, (b) shutting the wellbore and allowing the servicing fluid to set into place for a period of time, and (c) repeating steps (a) and (b) until the permeability of a structure within the wellbore is reduced by about 50%.
