Title: CHEMICALLY TAGGED DRILLING FLUID ADDITIVES
Abstract:
A method, system, and apparatus for using and testing chemically tagged drilling fluid additives. In one embodiment, the method comprises: circulating a drilling fluid in a wellbore, wherein the drilling fluid comprises a chemically tagged drilling fluid additive; and extending the wellbore into one or more subterranean formations while circulating the drilling fluid. A system comprising: a drilling fluid comprising a chemically tagged drilling fluid additive; a drill string comprises a drill bit and a downhole tool; a data processing system operable to receive measurements from the downhole tool to produce a visual representation of the chemically tagged drilling fluid additive in a subterranean formation or a filter cake. An apparatus comprising: a vessel for holding a quantity of a drilling fluid a filter media; a mud sensor; a cake sensor; an outlet sensor; a data processing system coupled to the mud sensor, the cake sensor, and the outlet sensor.
