ABSTRACT:
A method of determining fluid influx or loss from a well being drilled from a floating vessel and using a drilling fluid, the method comprising monitoring the flow of fluid from the well to obtain a varying signal indicative of the variation in flow from the well, monitoring the heave motion of the vessel to obtain a varying signal indicative of said motion, using the signal indicative of the heave motion to calculate the expected variation in fluid flow from the well due to said motion, using said calculated flow to correct the varying flow signal to compensate for any flow component due to heave motion and monitoring the compensated signal for an indication of fluid influx or loss from the well.
