摘要

Method for characterizing a pressure of an earth formation crossed by a borehole during drilling of the borehole, a method to determine a pressure of a subsurface formation surrounding a well bore.Method for detecting inflow and flow into a hole of the well from an earth formation surrounding the well bore are provided an apparatus and methods of drilling with profiling to measure potential flow in an earth formation. The apparatus and methodologies can be used to locate relevant information on the drilling operations.Particularly, since the measurement of the potential runoff refers directly to the flow of fluid, the measurements of the potential of flow can be used to track flows of fluids in the formation.In turn, this information can be used to locate relevant information about the operations of drilling, such as drilling conditions under balanced pressure abnormal in training, open fractures, the permeability of the formation, and pressure of the formation.
