Abstract: A ferromagnetic disk is removably installed in a wellbore. The disk can be installed in the wellbore during oil and gas well completion and production activities to maintain pressure within the wellbore and then can be dislodged. More specifically, a strong magnet is installed within a magnetic tool to dislodge and remove a ferromagnetic disk without breaking the disk. The strong magnet can be a neodymium magnet, electromagnet, or other types of strong magnets.

Abstract: A valve assembly (1) has a valve (14), for example a flapper valve, that is contained within an axially movable valve housing (11) in the form of a cartridge (10) that is received within the bore of a tubular member (5). More than one cartridge (10) may be connected in series.

Abstract: A system for tracking and guiding a downhole tool underground along a desired borepath. GPS measurements are taken by a GPS unit at desired waypoints on the ground surface that overlays the desired borepath. A planned route for the downhole tool to follow underground is generated from the GPS measurements of the waypoints. A tracker is used to track the location of the downhole tool underground while drilling a borepath. GPS measurements of a series of above-ground locations that overlay the borepath created by the moving downhole tool are taken and sent to the processor. The processor checks for deviation between the GPS measurements of the above-ground locations and the planned route and provides directions to correct the borepath of the downhole tool in response to the deviation.

Abstract: A horizontal directional drilling rig is described. The rig can be entirely electrically powered. The performance (or “health”) and/or the life cycle of individual components of the rig can be electronically monitored. This permits identification of specific individual components that are performing in a substandard manner or are not performing properly or have reached the end of their life cycle. Individual improperly performing components or components at the end of their life cycle can thus be specifically identified. The improperly performing component(s) or components at the end of their life cycle can then be replaced. In some embodiments, when a component is identified as performing improperly, the operation of other, properly functioning components of the rig can be modified accordingly to account for the improperly performing component.

Abstract: An oil-water fractionation system is positioned within a wellbore on a subsurface end of a production tubing proximate to a production region. The fractionation system includes a permeable hydrophobic media for preferentially conveying an oil-enriched stream (reduced water-cut presence) from the production region into the production tubing, and a permeable oleophobic media for preferentially conveying a water-enriched stream (reduced oil-cut presence) into a second flow path. The permeable hydrophobic media and the permeable oleophobic media are in simultaneous hydraulic communication with the production region. The permeable hydrophobic media is manufactured with a relatively high effective permeability to oil, allowing the oil-enriched stream to flow through the permeable hydrophobic media into the production tubing.

Abstract: A baffle system for use in well casing having a plurality of landed subs therein, for progressive injection of a fracking or treating fluid into a hydrocarbon formation via existing or created perforations in the well casing.

A method of using the baffle system is also disclosed.

Specifically, the system allows for easily and accurately digging a plumb hole.

Abstract: Tools, for example, fixed cutter drill bits, may be manufactured to include hard composite portions having reinforcing particles dispersed in a continuous binder phase and auxiliary portions that are more machinable than the hard composite portions. For example, a tool may include a hard composite portion having a machinability rating 0.2 or less; and an auxiliary portion having a machinability rating of 0.6 or greater in contact with the hard composite portion. The boundary or interface between the hard composite portion and the auxiliary portion may be designed so that upon removal of the most or all of the auxiliary portion the resultant tool has a desired geometry without having to machine the hard composite portion.
