Formation volumetric evaluation while drilling
Patent
·
OSTI ID:6777886
This patent describes a method for investigating properties of subsurface formations traversed by a borehole. It comprises: deriving a drilling signal indicative of the resistance of the formation to being drilled by a drill bit; deriving additional signals indicative of formation properties; and in response to the drilling signal and to the additional signals, deriving a volumetric analysis of the subsurface formation.
