Abstract: A flow rate control system includes a housing and a valve assembly slidingly disposed within a housing inner bore. The housing includes bypass openings. The valve assembly includes a valve and an orifice disposed in a valve inner bore. The valve includes a plurality of valve bypass bores extending axially through a valve collar. The valve assembly slides between closed and fully open positions. A spring biases the valve assembly toward the closed position in which the valve closes the housing bypass openings. In the open position, a bypass fluid path is formed including the valve bypass bores and the housing bypass openings. The valve assembly is flow rate controlled in the closed position and pressure controlled in the open position. The valve assembly may slide within a sleeve assembly including sleeve bypass openings, which connect the valve bypass bores and housing bypass openings in the bypass fluid path.

Abstract: A bit saver assembly having an inner valve sleeve that actuates upon the weight-on-bit (WOB) of the drill bit exceeding a threshold value to overcome the countervailing force provided by a spring contained within the bit saver assembly and the internal flow pressure of the drilling fluid at the area of the inner valve sleeve. Actuation of the inner valve sleeve opens a fluid passage to the wellbore annulus resulting in a reduction of drilling fluid flow pressure and the stretch of the drill string thereby reducing WOB of the drill bit without operator assistance.

Abstract: A plug used in the hydraulic fracking of hydrocarbon wells. The plug, known as a frac or bridge plug, contains one or more containers housing a chemical substance such as a solid, liquid, or gel composition. The composition may constitute or include a cleaning agent, friction reducer, suspending agent, or other wellbore additive. For example, the composition may constitute or include epoxy components, resins, thermoplastics, dry add friction reducers, dry add gel, dry add pipe on pipe, similar agents, or any combination thereof. The containers can include the same chemical substance or a variety of chemical substances. During drill out of the plug, the containers rupture and release the chemical substance into the wellbore. The released chemical substance, if a cleaning agent, assists in the cleaning of the milled-plug pieces from the wellbore.

Abstract: Methods and systems for diverting the flow of fluids within a wellbore are disclosed. The methods and systems use a flow conveyed diverter pack, which includes a package portion and a wing portion. The package portion may contain a ball (a.k.a. a diverter ball) and may contain additional components. The diverter pack may be formed by sandwiching a diverter ball between films of a flexible material, for example, films of a dissolvable polymer. The diverter pack may be deployed in a wellbore, whereby the pack is conveyed by fluid flow to an opening to be sealed. The diverter pack seats upon the opening, thereby diverting flow from the opening.

Abstract: An integrated milling and production device. The device includes a production housing, a connector, a motor, and a milling bit. The production housing has a central bore with at least one flapper valve pivotally disposed therein and an actuator. Upon completion of milling operations, the connector may be disengaged from the production housing. The production housing may be repositioned in the well. Activation of the actuator permanently opens the flapper valve to permit the flow of production up the production housing to the well surface. The actuator may be a piston.

Abstract: A mechanically locking hydraulic jar device includes an outer sleeve, an inner sleeve partially disposed in an inner bore of the outer sleeve, and a mechanical lock engaging the outer sleeve and the inner sleeve in a default position to axially secure the inner sleeve to the outer sleeve. Activation of the hydraulic jar disables the mechanical lock to allow axial movement of the inner sleeve relative to the outer sleeve, which generates an impact force when the inner sleeve reaches an activated position. The hydraulic jar device also includes an upward block and a downward block configured to limit the upward and downward axial movement, respectively, of the inner sleeve relative to the outer sleeve when the mechanical lock is disabled.

Abstract: An integrated milling and production device. The device includes a production housing, a connector, a motor, and milling bit. The production housing has a central bore with at least one flapper valve pivotally disposed therein and an actuator.

Activation of the actuator permanently opens the flapper valve to permit the flow of production up the production housing to the well surface. The actuator may be a piston.

Abstract: An integrated milling and production device includes a production housing having a central bore, one or more flapper valves pivotally disposed within the central bore, and an actuator disposed within the central bore. The flapper valves are closed in a default position. Activation of the actuator permanently opens the one or more flapper valves. A connector is selectively secured below the production housing, a motor is secured below the connector, and a milling bit is secured below the motor. The motor rotates the milling bit. Activating the connector disconnects the connector from the production housing. The actuator may be a piston disposed above the flapper valves in a milling position and disposed through the flapper valves in a production position to open the flapper valves. In the production position, a fluid may flow from the wellbore through the production housing's central bore and to the surface for collection.
