Abstract

A method for determining a hydrostatic Component (PHs) of a downhole pressure during a drilling operation, comprising the steps: extending a drill string (1) into a borehole (2), the drill string (1) having a tool (3) comprising a pressure sensor (6), a transmitter (5) and a power generator (4) configured to receive drilling fluid from the drill string (1) and generate electric power to operate the tool (3); A method for deterministic mining a hydrostatic Component (PH) of a down hole pressure during a drilling operation, comp rising the steps: Extending your legacy a drill string (1) into a borehole (2), the drill string (1) having a tool (3) comp rising a pressure sensor (6), a transmitter (5) and a power generator (4) Configured To receive drilling fluid from the drill string (1) and generate electric power to operate the tool (3); pumping a drilling fluid through the drill string (1) at a predetermined flow rate (Qpump); pumping a drilling fluid through the drill string (1) at a predetermined flow rate (Qpump); calculating a motive speed (u, m) for the drill string (1), moving the drill string (1) at the calculated motive speed (u, m) while operating the tool (3) to transmit a measured downhole pressure (PpWd) to a surface location (7); calculating a motive speed (u, w) for the drill string (1), moving the drill string (1) at the Calculated motive speed (u, w) while operating the tool (3) two transmit a Measured down hole pressure (PpWd) to a surface location (7); and determining the hydrostatic component (PHs), the hydrostatic component being calculated as a function of the measured downhole pressure(PpWd). and deterministic mining the hydrostatic component (PH), the hydrostatic component being Calculated as a function of the Measured down hole pressure (PpWd).
