Abstract
A method for determining drilling fluid losses or gains by providing a drilling fluid, measuring a plurality of supply parameters of the drilling fluid, delivering the drilling fluid to a subsurface drilling operation, the subsurface drilling operation providing a returns drilling fluid, measuring a plurality of returns parameters of the returns drilling fluid, and determining change in composition, or loss of or gain of drilling fluid from a comparison between the supply parameters and the returns parameters.
