More Information
Summary:The aqueous phase of a drilling fluid can be provided with self-adjusting alkalinity by introducing a buffering system, where the buffering system includes a buffering agent, an acid or a base, and an inorganic salt, and where the pH of the aqueous phase is in the range of from about 8 to about 12. In one non-limiting embodiment, the pH does not vary by more than about 0.5 pH units after a variation in temperature of the drilling fluid of at least about 175° C. for at least about 200 hours.
