Abstract
Sized-bridging agents, wellbore fluid compositions including the agents, and methods utilizing said compositions control, reduce, or prevent fluid losses in wellbores and/or formation damages. One or more divalent organic salts disclosed herein are designed to help mitigate fluid loss by temporarily reducing the permeability of the formation around the wellbore. The sized-bridging agents include sized-divalent organic salts for forming one or more filter cakes to seal one or more portions of the wellbores thereby reducing rates of fluid loss and damages to formations.
