Abstract: A well treatment material for introduction into a subterranean formation is provided. The well treatment material can include a biocide collected onto a sorbent. The biocide can be capable of being desorbed at a generally constant rate over an extended period of time into the subterranean formation. The biocide can be an oxidizing biocide or a non-oxidizing biocide. The sorbent material can include one or more of an absorbent material and an adsorbent material. The biocide can be chlorine dioxide. The sorbent can be one or more of silica gel and graphite.

Abstract: Embodiments provide apparatus for testing a primary PCB of a native computing device, the apparatus including a plurality of fixture mounting posts selectively positionable in alignment with mounting holes for the fixture mounting posts to be received in the mounting holes to support the primary PCB on the apparatus, and a fixture frame configured to support the plurality of fixture mounting posts in a plurality of selected mounting post locations, and embodiments provide methods for testing a primary PCB.

Abstract: A pallet with hinged end walls, joined by detachable cross bars, may have a similar pallet stacked thereon. When the walls are collapsed, a superimposed identical pallet will have its U-shaped feet (if made of metal) or the body of the pallet base (if the latter is made of timber) nested inside corners defined by corner stub angle posts. When the walls a erected, the stacked pallet nests within corners provided by the end wall framing. A bag (having an optional roof supported by ridge rod Q) may be supported by the walls of the pallet and stiffened by battens within sleeves in the bag.

Abstract: Systems and methods for operating a circulation valve such that the valve will automatically close without the need for a ball to be dropped or other intervention from the surface. The circulation valve is autonomous and will preferably be actuated from an open to a closed position by a motive force such as a power screw. The valve includes an actuator that causes the valve to close in response to particular conditions, such as the passing of a predetermined amount of time, or wellbore conditions, such as pressure, temperature or position.

Abstract: A downhole tool includes a thru-tubing high expansion, elastomeric inflatable seal and a thru-tubing mechanical anchoring arrangement. A method for separating pressure in a wellbore including actuating a mechanical anchoring system of a thru-tubing downhole tool; inflating a high expansion inflatable elastomeric seal against the tubing subsequent to actuating said mechanical anchor.

Abstract: A liner hanger test packer assembly includes an axially translated liner top dressing mill having a calibrated shear mechanism for securing the mill at a first, top dressing position. Tool string load on the mill bearing upon the liner top in excess of the calibrated shear mechanism allows the mill to shift to a second axial position where abutment edges around the Mill base engage a tripping mechanism to drive slips against the casing wall above the liner hanger. The tripping mechanism also expands the packer seal against the casing I.D. above the liner hanger. No additional load may be imposed on the liner hanger after the anchor slips have engaged.

Abstract: A through tubing downhole tool, such as a bridge plug is delivered on coiled tubing. The setting process entails an initial pressurization to anchor the tool and compress its sealing element. The remainder of the needed force for setting the tool can come from an upward pull on the coiled tubing. Should more force than can be delivered from a pull on the coiled tubing be required to finish the setting and releasing process from the downhole tool, a jar or impact tool can be incorporated to boost the applied uphole force that is delivered from the pull on the coiled tubing at the surface. Alternatively, a pressure amplifier can be fitted to the coiled tubing so that a smaller pressure applied to the coiled tubing at the surface can deliver the required force to set and release from the downhole tool.

Abstract: An Internal Bottom Hole Assembly (IBHA) for a Coiled Tubing (CT) enables the CT to be used with other devices downhole. The IBHA includes a connector, a valve assembly and an emergency disconnect device, all of which are mounted internally in the CT. The connector couples to the inside of the CT by means of wedges that are urged against the inside wall of the CT. The valve assembly may be mounted either between the connector and the disconnect device or may be on the side of the connector away from the disconnect device. The valve assembly includes one or more flapper valves that are able to pass a ball through at a minimum flow rate of fluid, enabling the ball to be used to operate the disconnect device.
