Abstract: An apparatus for reaming a wellbore without rotating a tubular string that is extendable to a surface. A mandrel (102) is coupled to a downhole end of the tubular string. The mandrel (102) has at least one groove (110) in a sidewall portion thereof. A sleeve (112) is operably associated with the mandrel (102) such that longitudinal travel of the mandrel (102) relative to the sleeve (112) shifts the sleeve (112) between extended and contracted positions relative to the mandrel (102). A reamer shoe (122) is coupled to a downhole end of the sleeve (112). At least one coupling device (116) is operably associated with the sleeve (112) and extendable into the at least one groove (110) such that longitudinal travel of the mandrel (102) relative to the sleeve (112) caused the sleeve (112) to rotate relative to the mandrel (102), thereby rotating the reamer shoe (122).

Abstract: An adapter for connecting a casing annulus remediation system to a well having a wellhead with standard lateral ports. The adapter has a body with first and second ends. The first end of the adapter body has a substantially planar surface adapted to cover the lateral ports and be in abutting contact with the wellhead when the two are connected to one another. The second end of the adapter body has a planar surface positioned at an angle greater than 0 degrees and up to 90 degrees to the planar surface of the first end. The second end of the adapter is adapted to be connected to a casing annulus remediation system.

A wellbore servicing method comprises receiving a fluid at a first pressure, increasing the pressure of the fluid to a second pressure greater than the first pressure, feeding the fluid to a high-pressure pump at the second pressure, receiving the fluid from the high-pressure pump at a third pressure greater than the second pressure, and feeding the fluid to a wellhead at the third pressure is also disclosed.

Abstract: An eductor sub is used as a portion of a downhole debris removal apparatus. It features an eductor outlet port that is selectively closed for run in to allow flow pumped through a tubing string to all go to the lower end of the debris removal tool to fluidize the debris and help prevent the tool from getting stuck on the way to the desired depth. When the desired depth is reached a ball lands on a seat that is connected to a sleeve that is displaced to move the sleeve away from the eductor outlet so that future flow coming down the casing string will create a reduced pressure within the tool to draw some of the exiting flow after the eductor exit in a downhole direction along an annular space to the debris removal tool entrance for debris removal.

Abstract: A method of perforating a wellbore by forming a perforation that is aligned with a reservoir characteristic, such as direction of maximum stress, lines of constant formation properties, and the formation dip. The wellbore can be perforated using a perforating system employing a shaped charge, a mechanical device, or a high pressure fluid. The perforating system can be aligned by asymmetric weights, a motor, or manipulation from the wellbore surface.

Abstract: A method of sampling a subterranean formation fluid may comprise extracting a first fluid sample from a portion of the subterranean formation, altering a temperature of the portion of the subterranean formation, and extracting a second fluid sample from the portion of the subterranean formation having altered temperature.

The method may further comprise determining a property of the subterranean formation fluid.

Abstract: A method of actuating a well tool utilizing first and second pressure sources includes the steps of: placing an actuator chamber in communication with the first pressure source, thereby displacing a piston from a first position to a second position; and then placing another chamber in communication with the second pressure source, thereby displacing the piston to a third position. A multi-position actuator includes an operating member which displaces to operate a well tool, a first position of the operating member corresponding to a pressure source being in communication with a chamber and another pressure source being in communication with another chamber, a second position of the operating member corresponding to the same pressure source being in communication with both of the chambers, and a third position of the operating member corresponding to the pressure sources being connected to the chambers oppositely to that of the first position.

Abstract: A switching apparatus, system, and method configured to operate at least a dual line downhole tool via a single pressure source are provided. The switching apparatus may comprise a housing configured to contain a switching piston actuated by a fluid pressure source. The apparatus may further contain a switching valve comprising a first and second coupling passageway coupled to a switching valve housing comprising four ports. The switching piston may actuate the switching valve, alternating the coupling between a first configuration in which the four ports are communicatively coupled into two sets of ports and a second configuration in which the four ports are communicatively coupled into an alternate two sets of ports. The first configuration may configure the fluid pressure source to actuate the downhole tool in a first manner and the second configuration may configure the fluid pressure source to actuate the downhole tool in a second manner.

Abstract: A downhole tool, such as a packer or liner hanger, has a mandrel on which slips are disposed for engaging a surrounding tubular downhole. When the tool is being run in or out of the hole, at least one magnetic component magnetically retains the slip adjacent the mandrel so the slip can be held away from the surrounding tubular. When the tool is set downhole, the initial magnetic retention can be broken, and the slips can be moved away from the mandrel to engage the surface of the surrounding tubular.

Abstract: During the production of crude oil, naturally occurring paraffin can be deposited on the inside surfaces of production tubing. These wax deposits reduce the cross sectional area of the tubing and can reduce or completely halt the flow of oil from the well. Currently there are many different methods employed in oil fields around the world to combat paraffin problems, but none are one hundred percent effective. When the available methods fail completely, costly removal and replacement of the tubing must be performed in order to resume oil production. The hot anti-wax knife tool provides a previously unavailable method of melting a hole through the paraffin deposits in the production tubing in order to restore production. The tool utilizes rechargeable batteries in a novel arrangement which provides sufficient power to melt through paraffin using a uniquely designed heating element and cutting head.

Abstract: An overshot tool is provided for interconnecting and sealing between a lower tubular (C) in a well and an upper tubular (30). A tubular expander sleeve (36) and an overshot sleeve (26) are supported in a well on an upper tubular. The tool housing (60) encloses a plurality of axially stacked pistons (58, 68, 74), which generate an axial force to move the expander sleeve downward and radially expand a portion of a lower tubular to seal between an outer diameter of the lower tubular and an inner diameter of the overshot sleeve.

Abstract: A hydraulic head clamp assembly is integral with a drill head mounted on a mobile drill rig. A side-shift carriage is provided for shifting the drill head from side-to-side relative to a centerline of a drill rod string. The clamp assembly includes a rigid jaw mounted on the side of the drill head, and a movable jaw mounted adjacent to said rigid jaw with a space between the jaws for receiving the drill rod string. The movable jaw is connected to a pair of hydraulic cylinder actuators that are actuated via a hydraulic circuit to control the clamp action between the rigid jaw and the movable jaw. The clamp assembly can be used to retract a drill rod string from the ground without limiting access to the inner diameter of the drill rod, and can also be used to advance the drill rod into the ground via a static push.
