Abstract: A system and method for optimized control of an assembly for drilling a borehole comprises a self-tuning, multivariable controller and an optimization engine that manipulates the setpoints of the controller such that drilling performance may be continuously optimized. The method includes evaluation of a characteristic system time constant, using this constant to compute bit ROP, using computed ROP to compute process gains, which are used to tune the multivariable controller, automatically refining controller setpoints based on controller performance, and using an optimization engine to systematically adjust controller setpoints such that drilling parameters are optimized based on any of several performance indicators, or a weighted combination of performance indicators. The method further comprises using at least one performance indicators which may be computed using estimated bit ROP: bit wear parameter; gradient of cost per foot; gradient of bit ROP versus WOB; simplified mechanical specific energy; and hydraulic specific energy.

Abstract: An apparatus and method for downhole measurement during operation of a drilling system is disclosed. The apparatus (30) comprises: a first sensor (302) configured to detect a property of a subsurface formation (200); a radiation source (304) configured to, when triggered, emit radiation to excite a part (220) of the formation; a processing unit (308) configured to trigger the radiation source if a change of the property of the formation is detected; a second sensor (306) positioned at a known distance from the radiation source and operably connected to the processing unit, the second sensor is configured to detect said excited part of the formation and is more distant from a drill bit (104) of the drilling system than the radiation source is; the processing unit is further configured to, after the excited part of the formation is detected, calculate a rate of penetration of the drill bit based on the following: a time duration between the radiation source is triggered and the excited part of formation is detected, and the distance between the radiation source and the second sensor.

Abstract: An insert to convert a conventional rotary drill bit to a rotary steerable bit for a rotational directional drilling system. The insert comprises a cylindrical body adapted to be arranged within an intermediate space of the drill bit for receiving drilling fluid from a drill string and selectively directing the drilling fluid to nozzles of the drill bit. The insert may be rotatable and connected to a geostationary platform. Alternatively, the insert may be fixated in the drill bit, combined with a flow diverter connected to a geostationary platform. The insert is suitable to be introduced in the drill bit at a drilling location, including remote locations and off-shore rigs.

Abstract: A method, system and bit steering assembly for directional drilling of a borehole in a formation is presented. The method includes the steps of: providing a drill string having a central fluid passage extending along a longitudinal axis of the drill string for passing drilling fluid to the drill bit. The drill bit has a plurality of nozzles for expelling the drilling fluid, wherein each nozzle is arranged eccentrically with respect to the longitudinal axis. The method includes introducing a bit steering assembly, rotating the drill string, and pumping drilling fluid through the central fluid passage. The drilling fluid activates a first impeller of a first rotor section to rotate in a first direction, and activates a second impeller of a second rotor section to rotate in a second direction opposite the first direction. The method includes adjusting a coupling between the first rotor section and the second rotor section.

Abstract: Drilling mud properties in a mud recirculation system (13) of an oil and/or gas well drilling assembly (1) are automatically adjusted by an automated mud treating assembly (20,25) that is governed hierarchal primary and secondary optimization and control loops (30,31) that continuously keep the density, viscosity, pH and other mud properties within specifications set by a model-based tertiary optimization and control loop to ensure that the mud properties will lead to sufficient drilled cutting transport, borehole stability, drill bit hydraulics, and minimum friction torque and drag.

Abstract: The performance of oil/and or gas well drilling equipment is measured by: input and output performance sensor assemblies that monitor associated equipment input and output performance characteristics; and alerting an operator if there is an anomaly between the monitored input and output performance characteristics; and wherein furthermore electric or hydraulic power input characteristics supplied to drilling equipment, such as a mud pump, drill string hoist and top drive are compared with delivered output characteristics, such as mud flux, drill string weight and rotation to alert an operator if there is an anomaly between the measured input and output characteristics.

Abstract: An abrasive jet drilling system is employed for transmitting information from a downhole location to a surface location. A jet drilling system is provided, with a drill string extending from surface to a downhole location in a borehole. A fluid flow with a mixture of drilling fluid and a quantity of abrasive particles is generated in the drill string. The quantity of abrasive particles in the mixture is modulated in dependence of information obtained regarding a downhole condition, to generate data pulses downhole which are detected at surface. A transmitted downhole condition is determined based on the detected data pulses.
