Wellbore Fluids Comprising Mineral Particles and Methods Relating Thereto

Abstract

Mineral particles may provide for wellbore fluids with tailorable properties and capabilities, and methods relating thereto. Mineral particles may be utilized in methods that include introducing a wellbore fluid having a density of about 7 ppg to about 50 ppg into a wellbore penetrating a subterranean formation, the wellbore fluid comprising a base fluid and a plurality of mineral particles, and the wellbore fluid having a first viscosity; contacting at least some of the mineral particles with a linking agent so as to link the at least some of the mineral particles, thereby increasing the first viscosity to a second viscosity.

[0005]One embodiment of the present invention is to a method that comprises introducing a wellbore fluid having a density of about 7 ppg to about 50 ppg into a wellbore penetrating a subterranean formation, the wellbore fluid comprising a base fluid and a plurality of mineral particles, and the wellbore fluid having a first viscosity; contacting at least some of the mineral particles with a linking agent so as to link the at least some of the mineral particles, thereby increasing the first viscosity to a second viscosity.

[0006]Another embodiment of the present invention is to a method that comprises introducing a wellbore fluid having a density of about 7 ppg to about 50 ppg into a wellbore pen

Problems solved by technology

However, as the exploration and recovery of hydrocarbons expands to subterranean formations with harsher conditions (e.g., extreme temperatures, higher pressures, increased depths, and new lithologies) the complexity of wellbore fluids often increases.
