WELLBORE SERVICING FLUID HAVING HYDROPHOBICALLY MODIFIED POLYMERS

摘要

Embodiments of the present disclosure include a wellbore servicing fluid that includes a diluent, a hydrophobically modified polymer, and a base. The base provides the wellbore servicing fluid with a pH of greater than 10. The presence of the base in the wellbore servicing fluid helps to minimize changes in the viscosity of the wellbore servicing fluid when a deposit, or a kick, of salt is encountered during the drilling operation.

主权项

1. A wellbore servicing fluid, comprising:
a diluent; a hydrophobically modified polymer; and an amount of a base, where the amount of the base adjusts a pH of the wellbore servicing fluid to greater than 10 thereby providing a viscosity that decreases no more than 33 percent of a change of viscosity in a control solution measured at 30° C., when a predefined concentration of salt is present in each of the control solution and the wellbore servicing fluid.
