BRINE BASED FLUID LOSS PILLS COMPRISING CROSSLINKED POLYMER GELS AND SOLID SALT PARTICLES

摘要

A fluid loss pill that includes a crosslinked polymer gel, a brine, and solidsalt particles disposed in said gel is described. Further, a method forreducing fluid loss that includes pumping a selected amount of a fluid losspill into a wellbore leading to an oil-, condensate-, or gas-producingformation, the fluid loss pill including a crosslinked polymer gel, a brine,and solid salt particles disposed in said gel is described.
