  • Patent number: 10494868
    Abstract: A system for drilling a borehole according to the present invention includes a drill rig and a control system. The drill rig includes a drill, an air injection system and a water injection system. The control system, which is operatively associated with the drill rig, receives information from the drill rig that relates to at least one drill parameter. The control system processes information relating to the drill parameter, determines whether the drill parameter is within a predetermined specification for the monitored drill parameter, chooses a hole defect mitigation routine based on the monitored drill parameter when the monitored drill parameter is outside the predetermined specification, and controls the drill rig to implement the chosen hole defect mitigation routine.

  • Patent number: 10450850
    Abstract: Micro-Electro-Mechanical System (“MEMS”) tags having high and low resonant frequencies are used to detect the cured or uncured state of wellbore cement. The MEMS tags may be added to wellbore cement, and pumped downhole. An interrogation tool emits a signal at one or both of the resonant frequencies which, in turn, interacts with the MEMS tags to produce a response signal. Since uncured cement has a high attenuation, only the lower resonant frequency response signal is sensed by an interrogation device, thus indicating the cement remains uncured. When the cement cures, its conductivity drops and the attenuation of the higher resonant frequency response signal drops also, thus allowing that signal to be detected by the interrogation device and indicating the cement has cured.

  • Patent number: 10450838
    Abstract: A diverter valve housing is secured to an upper end of a pump. A shuttle in the diverter valve housing moves between an upper closed position and a lower open position. A floating ring has an exterior band that abuts an upper end of the shuttle to move the shuttle downward. The floating ring moves upward when the pump operates. A bushing abuts an upward facing shoulder in the floating ring and is adhered within the bushing by a layer of adhesive. The shuttle has upper and lower seals separated by upper and lower spacer rings. A stop ring between the spacer rings limits downward movement of the upper spacer ring and also limits upward movement of the lower spacer ring.

  • Patent number: 10364646
    Abstract: A downhole fluid flow control system includes a fluid control module having an upstream side, a downstream side and a main fluid pathway in parallel with a secondary fluid pathway each extending between the upstream and downstream sides. A valve element disposed within the main fluid pathway has open and closed positions. A viscosity discriminator including a viscosity sensitive channel forms at least a portion of the secondary fluid pathway. A differential pressure switch operable to open and close the valve element includes a first pressure signal from the upstream side, a second pressure signal from the downstream side and a third pressure signal from the secondary fluid pathway. The magnitude of the third signal is dependent upon the viscosity of the fluid flowing through the secondary fluid pathway such that the viscosity of the fluid operates the differential pressure switch, thereby controlling fluid flow through the main fluid pathway.

  • Patent number: 10358895
    Abstract: A resilient backup ring is shaped for insertion with a sealing ring into an annular groove in at least one of two close fitting members in order to limit extrusion of the sealing ring. The backup ring is split by a cut permitting the backup ring to be contracted in diameter for seating of the backup ring in the annular groove. The cut defines respective shapes in two ends of the backup ring that engage each other for latching the backup ring in a contracted diameter configuration. At least one of the two ends has a cavity for receiving a tool for applying force to move the two ends apart and unlatch the backup ring from the contracted diameter configuration and expand the diameter of the backup ring for removal of the sealing ring from the annular groove.

  • Patent number: 10337278
    Abstract: An improved method and apparatus for dropping a ball, plug or dart during oil and gas well operations (e.g., cementing operations) employs a specially configured valving member with curved and flat portions that alternatively direct fluid flow through a bore or opening in the valving member via an inner channel or around the periphery of the valving member in an outer channel. In one embodiment, the ball(s), dart(s) or plug(s) are contained in a sliding sleeve that shifts position responsive to valve rotation. An optional indicator indicates to a user or operator that a ball or plug has passed a selected one of the valving members.

  • Patent number: 10323478
    Abstract: The present disclosure provides a modular insert float system and method that can be inserted into a casing and attached to the casing internal surface by internal slips and sealing components. The system is modular in that three main components: an upper valve assembly, a lower valve assembly, and a pair of casing anchor and seal assemblies along with top and bottom shoes form a kit that can be used for virtually any casing of a given size regardless of the threads, casing material grades, length of joint, or other variations. Further, the system allows for insertion of the casing into the wellbore without damaging the formation from forcing wellbore fluid into the formation and causing the loss of wellbore fluid in the wellbore.
