    Abstract: An isolation valve system, method, and apparatus are provided that can isolate a wellbore and prevent fluids from exiting the well and prevent seawater from entering the well. The system can be a two-part design in some embodiments where a shear sub is selectively interconnected to a body via shearing screws. A sufficient force on the shear sub destroys the shearing screws and the shear sub is removed from the body. This movement rotates an actuator on the body, which in turn rotates a valve in the body to provide the isolating function during routine operation of a wellbore or during an emergency.

    Abstract: An apparatus, system and/or method for making observations down a wellbore are provided. The wellbore observation system may comprise a mandrel that can be run downhole, and telescoping tracks can be utilized to move a camera and semi-conforming inflatable bladder out of the mandrel and into the wellbore. Once the bladder is inflated, it displaces high turbidity fluid in the wellbore to allow the camera to move about a track and observe the wellbore unobstructed. An alternative embodiment allows the mandrel and telescoping tracks to be utilized with other tools to perform cleaning, fishing, diagnostic, and analytic operations.

    Abstract: A riser system is provided to eliminate the consequences associated with damage to the annular system while also maintaining the availability of critical safety systems. The riser system may comprise a customizable control housing and external seal control subs that facilitate reciprocation and rotation of a drillpipe or workstring while eliminating damage to the upper annular blow out preventer and allowing the upper annular blow out preventer to function as intended.

    Abstract: A lube and bleed casing adapter and related systems and methods are provided for a lubricate and bleed operation in a wellbore where heavy fluids are directly deposited downwell. The casing adapter allows a hose to be positioned downwell and to be operably connected to a tank of heavy fluid. Once, the heavy fluid is deposited, the casing adapter receives lighter fluids from the wellbore, and the casing adapter is operably connected to a return tank that stores lighter fluids. As a result, the casing adapter and related systems and methods save time as the heavy fluid does not need to sink downwell before the lighter fluid rises upward.

    Abstract: A device, system and method are provided for using a seal sub to isolate a well. The seal sub generally has a primary channel extending through the seal sub and seat positioned within the primary channel. As a ball setting tool passes through the seal sub and the seat, a ball connected to the setting tool with a shear pin contacts the seat and selectively connects to the seal sub. A predetermined force can be applied to the ball setting tool to break the shear pin, which leaves the seal ball in place, and the seal sub and the seal ball isolate the downhole pressures and contents from the uphole pressures and contents.
