The 2590S coiled tubing wellhead is installed directly on the casing master valve, using standard casing threads. The design includes a 2″ LP annular flow port and a 0.5″ NPT gauge port.
The integral union 2590S wellhead is designed to be run in conjunction with a full opening hydraulic annular control valve. This design allows downhole assemblies larger than the diameter of the coiled tubing to be deployed in the well. The design includes a 2″ LP annular flow port, as well as a 0.5″ NPT gauge port.
The model DN wellhead is designed for use with coiled or jointed tubing and eliminates the need for a full-opening master valve on the production casing.
The Short Base Dual Wellhead provides a means for hanging two coiled tubing strings in a well and provides maximum safety and versatility at a low installed height. When used in conjunction with a hydraulic annular control valve, downhole equipment larger than the diameter of the coiled tubing can be installed or retrieved.
The Vertical Access Dual Wellhead provides a means for hanging two coiled tubing strings. The integral pack-off and slip design, along with the unique upper valve swivel connections, provides maximum safety and versatility at a low installed height.
The Flanged Wellhead system is primarily used where coiled tubing is to be installed on existing wells. By design, the hanger and optional flow tee assembly become part of the original wellhead. The hanger, and slip and seal set can be manufactured for compatibility with various well conditions, including high temperature and high-pressure.
The 2590R Threaded Hanger has set the standard for reliability and economy for coiled tubing completions. The 2590R is a compact hanger used as a strip-thru style with the added feature of a hydraulic pack-off.
The 2590R-2 and 2590R-3 hangers provide the same proven reliability of the 2590S and 2590R hangers but allow coil tubing sizes up to 2-3/8″.
The 2590S Threaded Hanger is designed for lower pressure wells and handles coiled tubing sizes up to 1.75.. Like the 2590R, the primary seal is enacted as the string weight compresses the packing element through the slip cone. The lock-down cap provides additional compression force on the slips and packing element for a secure pressure seal against the coiled tubing. The steel alloy retaining ring securely retains the packing element in the body. It can be removed easily to facilitate field replacement of the packing element.
The work-through style hanger body uses a two-piece split seal and slip assembly that attaches to the coiled tubing string after it is run in and is at hang-off depth. The slip and seal assembly is fastened to the coiled tubing string and lowered into the hanger bore to seat on a shoulder in the hanger bore, and then it is locked in place with anchor bolts. During well completion operations, a Select 5. ID pressure window and 5. ID Annular Control Valve are used to lubricate the slip and seal assembly into the lock-down position.
The Short Base Dual Hanger provides a means of landing dual-coiled tubing strings or, used in single-string segregated application, as a clean-out access to the casing annulus above a packer. Installation of the dual hanger to the annular control valve is easily achieved with the integral hammer union.
The Vertical Access Dual String Hanger permits the installation of larger-coiled tubing strings in the well. By design, the tubing strings remain near-vertical for easy access.
The Select Triple Base Hanger is a unique innovation for deployment of a downhole hydraulic powered pump for dewatering gas wells. The hydraulic pump is deployed into the well simultaneously on three coiled tubing strings. The completion consists of two strings that carry hydraulic power fluid and one string for fluid production.
The CT Split Seal Flanged Hanger uses the quad BOP of the coiled tubing service unit to seal well pressure and support the string weight, while the slip and seal assembly is being installed on the tubing string. A pressure window is installed above the quad BOP. The slip rams of the quad BOP hold the string weight, while the pipe rams contain well pressure. With the anchor bolt lock-down system, positive sealing is assured regardless of string weight. After the slip and seal set is installed in the hanger body, push force from the injector is applied to the string.
The CT Flanged Hanger may be used with higher surface pressure, with or without the quad BOP system, to install the coiled tubing string. When used without the quad BOP, the integral hydraulic pack-off provides a positive seal on the tubing string, while the injector and reel brake of the coiled tubing service unit hold the string weight during slip installation and removal.
The AutoCoil Hanger is a self-contained mechanical hanger that uses an automatic slip assembly to anchor and lock the coiled tubing from upward or downward movement in the well. The AutoCoil Hanger eliminates the need of an access window, thereby improving performance, safety and time efficiency on coil hang-off operations. A stripper element at the top of the hanger prevents debris from falling alongside the coil, eliminating potential problems when setting the slips.
The Hydra Tubing Head is a unique side-entry product that allows coiled tubing access to the casing annulus for dewatering or clean-out operations. The design allows coiled tubing deployment through the side-entry port, utilizing a coiled tubing unit; thus eliminating the need for a service rig to pull/run the jointed pipe. Multiple side outlets provide the option for data acquisition, telemetry, or monitoring of well conditions, such as temperature and pressure.
The Select Energy Adjustable Thread-On Casing Head provides a cost-effective method for isolating the production/surface casing annulus. The Casing Head is threaded directly onto the surface casing with either a pin or box-down configuration. Sealing plates provide an annular surface barrier that may be adjusted to seal against the production casing, even in situations where the production casing is not centralized within the surface casing.
The Select Energy Fixed Thread-On Casing Head provides a cost-effective method for isolating the production/surface casing annulus. The Casing Head is threaded directly onto the surface casing with either a pin or box-down configuration. Sealing is provided by O-rings contacting the production casing. The installation requires no welding on either the surface or production casing strings, eliminating potential cracks and inspection costs.
The Hydraulic Annular Control Valve has been developed to provide annular control in well completions with coiled tubing. The full bore configuration allows large OD tools to be incorporated in the tubing string. When installed initially on new completions, or when re-completing existing wells, the hydraulic annular control valve provides well control and downhole tool options not possible with conventional wellhead valves.
Dual Barrier CT Hanger
The Safety Set Dual Barrier Coiled Tubing Hanger is an API flanged Coiled Tubing Hanger designed to provide a high level of safety and integrity for single or dual barrier requirements in all wellbore conditions.
