Abstract
An example method for determining downhole conditions in a subterranean formation during a drilling operation may include introducing non-formation gas into a flow of drilling fluid through a fluid conduit in fluid communication with a drill string disposed within a borehole in the subterranean operation. The non-formation gas may be received from the flow of drilling fluid through a return line in fluid communication with the borehole. A downhole condition may be determined based, at least in part, on the received non-formation gas.
