Abstract: A method of electrically logging a section of a wellbore includes circulating an oil-based wellbore fluid within the wellbore and allowing filtration of the oil-based wellbore fluid to form a conductive filtercake on a wall of the wellbore; placing within the wellbore a wellbore logging tool with at least one pad capable of applying a current to a portion of the conductive filtercake and wellbore wall; applying electrical current from the at least one pad; and collecting an electrical log of the portion of the wellbore that has had electrical current applied thereto.

Abstract: A method of performing a wellbore operation may include circulating an oil-based wellbore fluid having a conductive material therein within a wellbore, the oil-based wellbore fluid having a conductivity of at most 0.02 S/m when measured at 20 kHz; and forming a filtercake having a conductivity at least two orders of magnitude higher than the oil-based wellbore fluid on at least a portion of a wall of the wellbore.

Abstract: Methods may include quantifying the concentration of residual free amine and/or free carboxylic acid in a product mixture prepared from a reaction of a multireactive species and a fatty reagent; verifying that the concentration for the free amine and/or free acid in the product mixture is within an acceptable threshold for a given application; and combining the product mixture with one or more wellbore fluid components to generate the wellbore fluid. In another aspect, methods may include including reacting the multireactive species and a fatty reactant to generate a product mixture; quantifying the concentration of residual free amine and/or free carboxylic acid in the product mixture; verifying that the concentration for the free amine and/or free acid in the product mixture is within an acceptable threshold for a given application; and collecting the product mixture.

Abstract: A method of formulating an oil-based wellbore fluid, the method comprising adding at least a plurality of conductive carbon black agglomerates or pellets having an average size of at least 500 μm to an oleaginous base fluid, and applying energy to the oil-based wellbore fluid to disperse the plurality of conductive carbon black agglomerates or pellets into the oleaginous base fluid as finer particles than the agglomerates or pellets.
