  • Patent number: 11512543
    Abstract: In a method for quantifying a volumetric flow rate of a flow of drilling mud in a floating structure for subsoil drilling, a flowmeter and a detection device are provided on a floating structure for subsoil drilling. The flowmeter generates a flow signal. The detection device generates a heave signal representative of a vertical heave of the floating structure. A processor transforms the flow signal into a first spectrum in the frequency domain and the heave signal into a second spectrum in the frequency domain. The processor compares the first spectrum with the second spectrum, obtaining a resultant spectrum. The processor transforms the resultant spectrum into a resultant signal in the time domain. The processor determines a mean value of the flow signal, adds the resultant signal to the mean value, obtaining a quantification of a flow of drilling mud in the floating structure.

  • Patent number: 11466567
    Abstract: A formation tester consists of an upper assembly, an impeller unit, a straddle packer unit, and an inverted reservoir description tool string. The upper assembly seals off the wireline cable at the rig and connects the wireline cable to the formation tester. The impeller unit includes an upper turbine which converts hydraulic power from circulation of drilling mud into mechanical power. The mechanical power is used to drive a lower impeller which is capable of pumping formation fluids at high flow rates. The straddle packer unit isolates a portion of the formation tester which is open to the borehole to allow entry and exit of formation fluids through the formation tester. The inverted reservoir description tool string contains a combination of formation description modules which are inverted from traditional reservoir description tool modules to allow fluid flow paths to bypass electrical components.

  • Patent number: 11339620
    Abstract: A closed-loop hydraulic drilling system generates choke characteristic curves or data that more accurately reflects the relationship between the commanded choke valve position and the resulting pressure drop across the choke valve for a given flow rate and fluid density. The choke characteristic curves may be generated through a calibration procedure and then used during normal operations to more accurately monitor return flow and manage wellbore pressure. The specific gravity of an injected calibration fluid and pressure drop across the choke valve may be determined and correlated to the current choke valve position to reflect the choke characteristic curve in situ, thereby providing for more precise control of wellbore pressure and enabling condition monitoring of the choke valve. In addition, an improved closed-loop hydraulic drilling system does not require a flow meter, enabling the adoption of MPD systems in low-specification and economically constrained applications.

  • Patent number: 9828817
    Abstract: A latching assembly has a tubular housing having an outer surface and an inner surface that defines an inner bore. Latch members are carried by the housing that have a latch position that extends out from the outer surface and a release position that is retracted from the latch position. A plurality of gripping members are pivotally attached to the housing. The gripping members are pivotally attached to the tubular housing and move between a gripping position wherein the gripping members extend into the inner bore and a retracted position. An actuator engages the latch members and the gripping members and moves between a first position and a second position. The actuator moves the latch members from the latch position to the release position and the gripping members from the retracted position to the gripping position as the actuator moves from the first position to the second position.

  • Patent number: 9822630
    Abstract: The disclosure relates to a system and method for determining whether a kick or loss has occurred from a well in real time, wherein the well has a marine diverter having a rotating control device. The marine diverter system may measure flow rate in real time of a drilling fluid entering the wellbore and provide a means of measuring flow rate of the drilling fluid out of the wellbore and riser. The marine diverter system may further determine displacement and velocity of displacement of rig heave motion in real time and use the foregoing steps, given a known internal diameter of the riser and a known external diameter of a drill pipe, and employing a drilling fluid volume balance equation: (Volumetric flow rate-in)?(Volumetric flow rate-out)?(Change in riser annular Volume per unit time)=X, to determine whether the kick or loss has occurred in real time.

  • Patent number: 9784100
    Abstract: A method, apparatus and computer-readable medium for determining an influx at a wellbore is provided. A flowback parameter is obtained for a plurality of flowback events at the wellbore prior to a current flowback event. An average of the flowback parameter (?) and a standard deviation (?) of the flowback parameter is determined from the plurality of prior flowback parameters. An alarm threshold is set based on the determined average and the standard deviation. A current flowback parameter is measured and the influx is determined when the current flowback parameter meets the alarm threshold.

  • Patent number: 9670744
    Abstract: A method for marine wellbore drilling includes pumping drilling fluid through a drill pipe in a wellbore below a bottom of a drilling riser extending from proximate the bottom of the water to a drilling platform on the surface. Drilling fluid returning from the wellbore is discharged from a position proximate the bottom of the drilling riser into a fluid line extending from the position to the platform. Drilling fluid in the fluid line is pumped from a depth in the body of water shallower than the position of discharge of fluid from the riser and at which a column of fluid in the marine drilling riser at an elevation above an intake of a pump in the fluid line exerts a dynamic fluid pressure exceeding fluid pressure at the intake of the pump. The riser fluid level is selected to provide a selected fluid pressure in the wellbore.

  • Patent number: 9646115
    Abstract: A method to determine a drilling fluid density limit involves obtaining a geomechanical model of a target borehole, generating a depth of damage model of the target borehole to describe a relationship between a drilling fluid pressure and a depth of damage representing a modeled amount of yielded rock surrounding the target borehole, where the modeled amount of the yielded rock is calculated using a stress model according to a pre-determined failure criterion, and calculating, using the depth of damage model and the geomechanical model, the drilling fluid density limit as a function of the subterranean formation depth, where the drilling fluid density limit maintains the depth of damage at a target level for the target borehole, where the drilling fluid density limit corresponds to a depth gradient of the drilling fluid pressure, where the target borehole is drilled based at least on the drilling fluid density limit.

  • Patent number: 9624767
    Abstract: A method and assembly to produce data pulses in a drilling fluid in a drill string. The assembly comprises a shear valve that includes a valve member mounted in a valve passage in fluid flow communication with a fluid flow conduit of a drill string to which the assembly is connectable. The valve member is connected to a reciprocation mechanism comprising a rocker, a driven crank arrangement, and a slider member that provides a sliding coupling between the crank arrangement and the rocker. The slider member is pivotally connected to the crank arrangement, is keyed to the rocker for angular displacement about a valve axis, and is radially slidable relative to the rocker, so actuation of the crank arrangement causes angular reciprocation of the rocker, and hence of the valve member, about the valve axis, to produce data pulses in the drilling fluid.

  • Patent number: 9598937
    Abstract: The present disclosure relates to a downhole rotating magnetic field generator, wherein a stator assembly is formed by fixedly connecting a guiding stator, windings, and a body together, and a rotor assembly is formed by mounting a turbine rotor and a permanent magnet together. Between the stator assembly and the rotor assembly, sliding bearings are arranged and small mud passages are formed. There is no metal isolation between the rotor and the stator for cutting through the magnetic lines of force, so that the eddy current loss is relatively small. Meanwhile, with mud flowing through the passages as lubricant, overheating of the generator can be prevented and high power output can be ensured.
