A method of electrically logging a section of a wellbore includes circulating a wellbore fluid within the wellbore, the wellbore fluid including a base fluid; and a crosslinked and branched polymeric fluid loss control agent formed from at least an acrylamide monomer and a sulfonated anionic monomer; wherein the fluid loss control agent has an extent of crosslinking that is selected so that the fluid loss control agent has a viscosity that is within a peak viscosity response of the viscosity response curve; placing within the wellbore a wellbore logging tool capable of applying an electrical current to the wellbore; applying electrical current from the logging tool; and collecting an electrical log of the portion of the wellbore that has had electrical current applied thereto.
