  • Patent number: 11255144
    Abstract: Disclosed herein are various embodiments of methods and systems for drilling an oil or gas well safely and efficiently using underbalanced or near-balanced drilling techniques, wherein the primary means of pressure control is a Annular Pressure Control Diverter positioned below the BOP stack, with a return flow pattern where no drilling fluid returns up the (traditional) annulus between the drill pipe and the production casing and instead drilling fluid returns up the annulus between the production casing and intermediate casing. Drilling fluid returns flow through a wellhead, instead of a flow spool conventionally located below an upper RCD, and hence to the drilling choke. This drilling approach eliminates the need for hydraulic fracturing and preserves the natural fracture system of the producing formation while providing additional safety measures. It also prevents the accidental or deliberate discharge or flaring of methane during drilling and production.

  • Patent number: 10961781
    Abstract: Anti-rotation pad assemblies are provided for restraining rotation of a non-rotating housing in geologic drilling system. The anti-rotation pad assemblies include extensible members, which extend from an internal cavity in the anti-rotation pad assemblies and are capable of engaging a wellbore wall. The extensible members may include rollers that are biased radially outwardly to engage the wellbore wall such that the anti-rotation pad assemblies may move axially within the wellbore while restraining the non-rotating housing in a particular rotational orientation. Flow ports are defined in the anti-rotation pad assemblies to encourage mud flow through the internal cavity, and thereby discourage the accumulation and solidification of drilling fluids around the extensible members. The extensible members thus remain free to move under the bias of a biasing mechanism within the internal cavity and can thus effectively maintain the rotational orientation of the non-rotating housing in the wellbore.

A method includes: coupling a whipstock to a BHA with a retention system, including: a retractable bolt biased to retract into the BHA; and a retraction actuator configured to resist the bias of the retractable bolt; and after the whipstock and BHA have been disposed in a wellbore, activating the retraction actuator so that retraction of the retractable bolt ensues.

  • Patent number: 10697252
    Abstract: A valve assembly for reversibly governing fluid flow through coiled tubing equipment. Valves of the assembly may be directed by a telemetric line running from an oilfield surface. In this manner, valve adjustment and/or reversibility need not require removal of the assembly from the well in order to attain manual accessibility. Similarly, operation of the valves is not reliant on any particular flow rate or other application limiting means. As such, multiple fluid treatments at a variety of different downhole locations may take place with a reduced number of trips into the well and without compromise to flow rate parameters of the treatments.

  • Patent number: 10689973
    Abstract: A dimensional characteristic of a borehole is determined from a rotary drilling system having a housing and an anti-rotation device with one or more drag members that engage a borehole wall. A sensor detects a biasing force on the drag members and transmits a signal representative of the force on the drag member to a control unit. The control unit determines a dimensional characteristic of the borehole based on the force on the drag member of the anti-rotation device.

    Abstract: A drill bit may include rings that are rotatable at different speeds along a single axis. The drill bit may be coupled to a motor using multiple driveshafts. Each driveshaft can be coupled to one of the rings. Each driveshaft may transmit a different amount of torque from the motor to the rings to allow each ring to rotate at a different speed. In some aspects, the driveshafts may include a center driveshaft coupled to a pilot ring of the drill bit and an outer driveshaft coupled to an outer ring of the drill bit. The drill bit may include additional rings coupled to the motor by additional driveshafts.

  • Patent number: 10519722
    Abstract: A reamer for enlarging an underground borehole comprises a plurality of cutter assemblies distributed azimuthally around a longitudinal axis of the tool. Each cutter assembly comprises a supporting structure and a plurality of hard faced cutters secured therein with a hard surface of each cutter exposed and facing in a direction of rotation of the tool and extending radially outwards from the tool axis to a radially outward extremity. These cutters are arranged in a sequence extending axially along the tool. In contrast with convention a1 cutter assemblies, the supporting structure comprises at least one radially outward-facing surface which is positioned to follow behind the leading face of at least one cutter as the tool rotates and which is aligned with the radially outer extremity of the cutter at the same radial distance from the tool axis. Thus the surface area available to contact the borehole wall and stabilize the positioning and motion of the rotating reamer is enhanced.
