Abstract: A side pocket mandrel for use within a gas lift system is configured to permit the exchange of valve pockets. The side pocket mandrel has a central body, a receiver that is laterally offset from the central body, and a valve pocket that is removably secured to the receiver. The valve pocket can be configured for a threaded connection with the receiver to permit the facilitated exchange of modular valve pockets at the receiver. Gas from the valve pocket can be carried to the central body of the side pocket mandrel through one or more external gas lines or one or more internal gas injection passages.

Abstract: A well sealing tool may include a hydraulic setting mechanism wherein a setting chamber is isolated after setting a sealing element in engagement with a wellbore. In one example, a setting mechanism includes a setting chamber housing positionable about a mandrel to define at least a portion of a setting chamber between the mandrel and the setting chamber housing. A setting port fluidically couples a through bore of the mandrel with the setting chamber. A valve element is biased toward a closed position within the setting port. A guide sleeve is disposed about the mandrel in a first position that props the valve element to an open position. The guide sleeve is moveable to a second position in response to a threshold pressure applied to the setting chamber to release the valve element to the closed position.

Abstract: Geologic material in a borehole is weakened by accelerating a projectile into contact with the material. A drill bit is then used to bore through the weakened material. To accelerate the projectile, an endcap is placed in a conduit using a source of gas. The endcap isolates the conduit from the external environment. A projectile is then positioned in the conduit above the endcap. Movable members within the conduit are operated in sequence to enable single endcaps and projectiles to be moved into the conduit. Gas from the conduit is evacuated into an annulus between the conduit and a surrounding conduit, and a propellant material is provided into the conduit. The propellant material applies a force to the projectile to accelerate the projectile into contact with the geologic material. A fluid is circulated down a second annulus outside of the surrounding conduit to contact the drill bit and remove debris.

Abstract: A spindle with a mechanism for transferring axial force from an inner drive assembly to an outer drive assembly. The spindle's inner drive shaft is connected to an inner member of a dual-rod pipe by a drive rod having a sliding sleeve. The sleeve is fixed rotationally with the drive shaft, but not axially. When axial force drives the drive rod toward the drive member of the spindle, the sleeve contacts a stop member which is paired to the outer drive assembly. The stop member may be a pair of dowel pins. Axial force is thereby transferred from the inner member to the outer member, allowing such forces to be absorbed by the outer member's larger drive components.

Abstract: A system for generating artificial permeability during the completion phase may include sensors that capture real-time data pertaining to a reservoir parameter, a formation parameter, or a tool condition parameter. The system may also include a drilling tool arranged in a wellbore to drill, using side drill bits, paths into a formation zone based on a drilling program. The system may also include an access module to access the real-time data captured by the sensors inside the well. The system may also include one or more processors configured to arrange the drilling tool in the wellbore, in proximity to the formation zone. The one or more processors may also be configured to cause an operation of the drilling tool based on the drilling program, update the drilling program based on the real-time sensor data, and cause an adjustment of the drilling of the paths based on the updated drilling program.

Abstract: A sonic-powered method is provided for horizontal directional drilling. The method includes positioning a drilling apparatus at one end of a desired path for a generally horizontal bore to be formed, and attaching a drill bit and a drill rod to a drill head. The method also includes advancing the drill bit and the drill rod into and through the ground along the desired path by advancing the drill head to move along the drill mast. A sonic oscillator of the apparatus applies sonic energy in the form of high frequency vibrations to the drill rod and the drill bit to cause the drill bit to penetrate through an underground formation in front of the drill bit along the desired path. The sonic vibrations help efficiently penetrate through different materials in underground formations. The drilling apparatus can also use sonic vibrations to install drill casings to stabilize the bore.

Abstract: A multilateral junction comprising a y-block and a port seal member. The y-block comprises a main bore, a lateral bore, and lateral port formed in the y-block. The port seal member is integrated within the main bore and has at least one of an opened, closed, and choked position. The multilateral junction also includes one or more gaskets configured to hydraulically isolate the lateral bore when the port seal member is in a closed position. The multilateral junction may further include a controller coupled to the port seal member for performing at least one of an opening, closing, and choking operation on the port seal member.

The multilateral junction is useful in applications that require pressure tight seals and minimal restriction of the internal diameter of a main bore.

Abstract: A production tubing is disposed in a wellbore. Hydrocarbons entrapped in a subterranean zone enter the wellbore. Multiple valves are disposed in the production tubing at respective multiple tubing locations. The multiple valves divide the production tubing into multiple stages. A presence of hydrocarbons in a first stage terminating at a first valve is determined and gas is injected into the first stage causing the hydrocarbons in the first stage to flow uphole through the first valve into a second stage uphole of the first stage. It is determined that the second stage is filled with the hydrocarbons and injection of the gas into the first stage is ceased. Multiple side chambers are disposed in the respective multiple stages. Determining the presence of hydrocarbons in the first stage incudes detecting a fluidic level of the hydrocarbons inside the first side chamber.

Abstract: A power condition system is disclosed for conditioning power for charging of at least one capacitive element of a pulse power electrode, where the electrical power is received from at least one of a downhole alternator or generator. The received electrical power is rectified and controlled for both voltage and current amplitude. The electrical power is then split into two parallel square wave signals. The electrical power is then transformed, using parallel high frequency high voltage transformers, to a high voltage signal. The high voltage signals are rejoined and rectified to produce a high voltage DC signal. The DC signal is smoothed at a high capacity inductor and output via a switching element to at least one capacitive element of the pulse power electrodes.

Abstract: An inflatable down hole bag includes an inflatable body for holding an inflation fluid and a container for holding one or more substances. The container is disposed inside of the inflatable body and includes a closure for keeping the one or more substances in the container when the closure is in an inoperative state.

Each chamber holds a respective one of the substances. The closure includes a stopper for closing a respective opening to one of the chambers. The closure further includes an actuator for removing each stopper from the respective opening so as to release each substance from each respective chamber.
