Abstract: A method and system for drilling a borehole in a subsurface formation, A method includes rotating a drill bit to remove formation material from the subsurface formation at an end of the borehole. A value of mechanical specific energy applied to remove the formation material is calculated. A value of drilling efficiency is calculated for drilling the borehole. Pore pressure of the subsurface formation in contact with the drill bit is calculated as a function of the drilling efficiency and the mechanical specific energy. Real-time operational decisions (such as adjusting density of drilling fluid or determining the final depth of the hole section) are made based on calculated pore pressure of the subsurface formation.

Abstract: An underreamer for increasing a diameter of a wellbore. The underreamer includes a body having an axial bore extending at least partially therethrough. A mandrel is disposed within the bore of the body and has a port formed radially therethrough. A sleeve is disposed radially-outward from the mandrel. The sleeve blocks fluid flow through the port in the mandrel when the sleeve is in a first position, and the sleeve is axially-offset from the port in the mandrel when the sleeve is in a second position. A flow tube is coupled to the mandrel. The sleeve moves from the first position to the second position when fluid flows through the flow tube and through a channel disposed in the mandrel. A cutter block is movably coupled to the body and is responsive to fluid flow from the axial bore through the port in the mandrel.

Abstract: An arrangement and a method for controlling at least one drill parameter when drilling in rock with a rock drill, comprising an impulse-generating device arranged to induce shock waves in a tool acting against the rock with a percussive force generated via a shock wave-generating pressure. The arrangement also comprises a rotation- generating device arranged to supply a torque to the impact device with a rotation generated via a rotation pressure, and a pressurisable damping chamber arranged to at least partially regulate the rock drill's contact with the rock via the prevailing pressure in the damping chamber, in which connection the shock wave-generating pressure is regulated depending on the rotation pressure. The arrangement comprises a control system arranged to: determine a first parameter value representing the damping pressure or feed pressure, determine a second parameter value representing the drill bit's rotation pressure, determine a deviation between the above second parameter value and a rotation pressure reference value, determine a parameter reference value depending on the above deviation and regulate the percussion pressure based on a function of the above deviation and the above parameter reference value.

Abstract: Method and device for controlling a rock drilling machine (51) comprising an impact device (5) for exerting a drilling tool (52) to impacts, a rotation motor (7) for rotating the drilling tool (52) and a feed motor (6) for feeding the drilling tool (52) against a ground (53). The pressure to an inlet (30) of the rotation motor (7) is sensed. When this pressure exceeds a first predetermined value (41) the pressure to an inlet (32) of the feed motor (6) is reduced with the aim of keeping the pressure to the rotation motor substantially constant. When the pressure to the inlet (30) exceeds a second predetermined value (42) the pressure to an inlet (31) of the impact device (5) is controlled inversely proportionally to the pressure to the inlet (30) of rotation motor (7).

Abstract: An arrangement in a rock drill comprising a shank (3) and a percussion piston (2) and lifting means for moving the shank (3) towards the percussion piston (2), and a method of controlling rock drilling. The arrangement comprises a lifting sleeve (7) around the shank (3) and a plurality of cylindrical lifting pistons (8a, 8b) around the shank (3). In the method, upon downward drilling, the magnitude of the feed force of the rock drill is decreased as the number of extension rods increases, and a force is set to act on some lifting pistons to move the shank (3) towards the percussion point.

Abstract: In some aspects, the present invention comprises a system and method for optimizing the control scheme used for drilling operations based on the complex and large data sets available in realtime during operation of a wellsite and based on existing model data available at the wellsite for past similar drilling operations. Such optimizations typically require downtime to quantify how the realtime values will factor into the control model, but the present invention allows for such optimization in realtime in a closed-loop system that will reduce the non-productive time associated with reservoir operations.
