  • Patent number: 11788357
    Abstract: An extendable member diagnostic assembly determines performance of one or more components of a rotary steerable system. Based on the determined performance, an operation can be altered, such as a drilling operation. Performance may be based on measurements received from one or more sensors associated with components of the extendable member diagnostic assembly. For example, performance may be based on the time to transition a valve between states where the valve controls actuation of an extendable member, downhole temperature, downhole pressure or any other factors that affect performance of components that are used to perform the drilling operation. A controller receives the measurements from the one or more sensors and updates baseline parameters to determine an accurate performance. Using real time data to determine performance increases efficiency of an operation by eliminating unnecessary replacement of components and indicating that a downhole tool should be retrieved prior to failure.

    Abstract: An improved leading end assembly for a HDD percussion boring system comprises a sonde housing, a percussion hammer and a tilted-face slant bit. The sonde housing body comprises a bent engagement feature and a shoe aspect that creates an asymmetrical cross section of the sonde housing. The percussion hammer is connected to the sonde housing via the bent engagement feature which is configured to position the percussion hammer on an angle relative to a longitudinal axis of the sonde housing. The tilted-face slant bit comprises a front face facet that defines a plane that is tilted relative to a plane that is perpendicular to a longitudinal axis of the bit shaft. Advantageously, embodiments of the solution do not include a bent sub component. Rather, the shoe aspect, the bent engagement feature and the front face facet collectively form an effective bend angle (as opposed to a single, abrupt bend angle imposed by a bent sub in prior art solutions).

  • Patent number: 10301880
    Abstract: An over-bit backreamer. The backreamer is configured to be placed over a bit without detaching the hit from a drill string associated with a pilot bore. The backreamer has an internal surface that conforms to a steering surface of the hit. Rotation is transferred from the bit to the backreamer at the internal surface. The backreamer further defines a flange which interacts with a feature, such as a heel, on the bit. The flange and heel form a shoulder which transfers pullback force to the bit. The backreamer comprises a pullback eye that pulls a product pipe back through the borehole.

  • Patent number: 10214971
    Abstract: Adjustment of the angle of a bent sub or other steering feature in a drill string relative to a reference angle of a downhole sensor is facilitated by a rotatable coupling between the bend sub and the sensor. The rotatable coupling may be rotated to align the high side with a reference indicia and locked at the set angle. Calibration of the sensor is facilitated and opportunities for certain measurement errors are eliminated. An embodiment provides a locking mechanism comprising tapered locking fingers which are clamped against a surface by a tapered collar. Rows of ceramic balls retained in circumferential channels may be provided to permit rotation while carrying tensile and compressional forces.

  • Patent number: 10000971
    Abstract: A method for steering a well comprises disposing a first orienting assembly and a second orienting assembly spaced apart along a circular inner peripheral surface of a housing. An orienting sleeve is rotatably supported between the first orienting assembly and the second orienting assembly, The orienting sleeve has an angled bore therethrough, wherein a first longitudinal axis of the angled bore is inclined by a predetermined angle to a second longitudinal axis referenced to a cylindrical outer peripheral surface of the orienting sleeve. A rotatable steering shaft is rotatably supported along the angled bore to control rotatable steering shaft bending. The rotation of the first orienting assembly, the second orienting assembly, and the orienting sleeve is controllably adjusted to control the steering direction of the rotatable steering shaft.

    Abstract: A rotary steerable tool has an inner mandrel having a longitudinal axis and an outer housing positioned along the inner mandrel. The outer housing rotates independently of the inner mandrel. The outer housing has an engagement member that moves axially relative to the outer housing and the inner mandrel between an extended position and a retracted position, and a transition surface having a slope relative to an outer surface of the outer housing. The engagement member moves along the transition surface between the extended position and the retracted position. In the engaged position, the engagement member extends outward from the outer housing to engage an inner surface of a well being drilled. An actuator selectively moves the engagement member along the transition surface from the retracted position to the extended position.
