A downhole tool for installing a gas lift valve in a well. The downhole tool may include a housing, a mandrel movably disposed with respect to the housing, a holder configured to hold the gas lift valve, and an arm supporting the holder. The arm may pivot between a retracted position in which the holder is adjacent the housing and an extended position in which the holder is disposed away from the housing. The mandrel and the arm may be operatively connected via a pin-slot joint having a pin disposed within a slot. The slot may have a first slot portion and a second slot portion. The pin-slot joint may prevent the arm from pivoting when the pin is within the first slot portion and permit the arm to pivot when the pin is within the second slot portion.

Wireless multi-stage completions for providing power to and telemetry communication with downhole device(s) are provided. A power generation system can be disposed along a production string to power down-hole devices. The power generation system can be driven by annulus fluid flow or production fluid flow and converts the fluid flow to electrical energy. The power generation system can be retrievably disposed in a side pocket mandrel.

The invention features a concentric mandrel and suspension element, which uses the same gas-lift valve used in a side bag mandrel. The application of the invention is proposed for wells with very low static pressure that operate with an intermittent pneumatic lift, enabling the production in these wells. The development of a concentric mandrel and the respective macaroni suspension element (1), allows the use of an insertable accumulation chamber, and at the same time allows the replacement of the gas-lift valve to be carried out with a wire unit, thus avoiding rig interventions, which are more expensive and time consuming.

Apparatuses and methods for positioning a flexible hose into a wellbore with a protective housing are disclosed. A flexible hose is contained within a protective housing and both are positioned into a wellbore to a desired depth. Pressure can be applied to an interior of the protective housing, and a packoff seals between the flexible hose and the protective housing, causing the pressure to eject the hose from the protective housing.

A tumbler ring apparatus, method, and system for deployment in a subterranean well at a setting location. The tumbler ring may have a generally oval shape with a major axis and a minor axis. The major axis defining a major diameter of the ring and the minor axis defining a minor diameter of the ring. The major diameter of the ring being larger than the inner diameter of the subterranean well at the setting location, and the minor diameter of the ring being smaller than the inner diameter of the subterranean well at the setting location. The ring is further configured to substantially deform to the inner circumference of the subterranean well at the setting location when tumbled by reducing the major diameter of the ring to cause the ring to generally take the shape of the inner circumference of the subterranean well.

A kickover tool for retrieving a used gas lift valve installed within a gas lift mandrel connected along a wellbore tubular string and installing a new gas lift valve within the gas lift mandrel. The kickover tool may include a housing, a first holder configured to hold the used gas lift valve, a first displacement mechanism operable to move the first holder between a retracted first holder position in which the first holder is adjacent the housing and an extended first holder position in which the first holder is spaced away from the housing, a second holder configured to hold the new gas lift valve, and a second displacement mechanism operable to move the second holder between a retracted second holder position in which the second holder is adjacent the housing and an extended second holder position in which the second holder is spaced away from the housing.

Embodiments include a core plug holding apparatus including a tubular member configured to be inserted into a side pocket of a mandrel, the tubular member having an uphole end, a downhole end, and a core plug section located between the uphole end and the downhole end, wherein the core plug section is used for housing of one or more core plug samples and wherein tubular member includes one or more orifices formed in the core plug section. Embodiments include a method of sampling a well including deploying one or more core plug holding apparatuses into one or more side pocket mandrels of a completion; holding the one or more core plug holding apparatuses in the one or more side pocket mandrels for an incubation period; and retrieving the one or more core plug holding apparatuses from the one or more side pocket mandrels after the passage of the incubation period.
