Fluted Swage & Adapter
The BSP Fluted Swage/Adaptor is designed to use between the tubing/tools string up to safety valve’s landing nipple. In the external surface of the Fluted swage/adaptor some slots machined which allow control line to be placed into and also get protected from any damage during the tubing movement.
Flow Coupling
The BSP Flow Coupling is used to protect the integrity of tubing from erosive turbulence. Flow couplings are often used above and below a geometric restriction in the flow path, depending on the well conditions. API recommended practices 14B advises use of flow couplings above and below safety valve.
Mill Out Extension
The Mill-Out Extensions provide a large ID below the packer seal-bore, which allows a single-trip packer milling tool to be used when tubing is run blow the packer assembly.
Top No Go Nipple
- The BSP Surface Set Seating Top No-Go Nipples are down hole tubing nipples that provide for the location of various wireline flow control devices in the production string. The location and number of Top No-Go Seating Nipples should be carefully considered in the completion planning stages to allow maximum versatility in the positioning of various flow control devices. These Nipples contain a no-go shoulder above of seal bore and a locking groove. The no-go shoulder is used to locate and set the flow control device that is being run into the well. When running the flow control device in the well, a no-go shoulder located on the flow control device will come into contact with the no-go shoulder of the seating nipple.
Features
- Honed sealing bores for maximum sealing performance.
- Seal-bore contoured and polished to pass packing without damage.
- Integral locking groove.
Benefits
- Land instrument hangers with geophysical devices such as pressure and temperature recorders.

Shifting Tool
The BSP Shifting tools are used to move the inner sleeve to its open or closed position in Sliding Side-Door Circulating Devices. The positioning tool engages the recess in the upper (or lower) end of the inner sleeve to permit the sleeve to be shifted by a jarring action.
The tool is designed to release itself only after the sleeve reaches its fully open or closed position. This automatic-releasing feature incorporates a releasing profile on the key itself that acts to compress the key spring and release the positioning tool. A shear pin is an added feature designed to release the tool in the event well conditions make it impossible to shift the sleeve.
A set of positive keys is available for this tool to permit upward movement of the inner sleeve of one among several sliding side-door circulating devices in one wellbore. These keys do not have a releasing profile. The positioning tool pin must be sheared to release.
- Special sizes and Profile are available upon request. 3.688 & 4.562 inch are common seal bore sizes in BSP design.
- The Product can be supplied in the following materials: L80-T1 (4140), L80-T2 (9%Cr), L80-T3 (13%Cr).
Kick-Over Tool
- The BSP Kick-Over Tools are wire-line service tolls that are used to install side pocket subsurface control devices into BSP side pocket mandrels, or to retrieve those devices as required. These tools must be used with either a running or a pulling tool. Especially suited for use in highly deviated wells, the kick-over tool consists of a fishing neck with a threaded pin connection on the upper end, a locating finger, kick springs, an arm assembly with a box thread connection on the lower end for attachment to a running or pulling tool and an arm housing with a nose on the lower end.
An upward movement of the tool through the chosen mandrel will position the locating finger in the mandrel orienting sleeve and rotate the tool into alignment with the mandrel pocket. The kick springs then pivot the arm to kick the attached running tool and control device or pulling tool outward, directly above the mandrel pocket. The arm housing protects the arm attached devices during installation and retrieval.

Other Completion Accessories
Wire-line Retrievable Latch
- The BSP Latch is wire-line latch designed with a spring loaded latch ring to be used on top mounted gas lift valves, dummy valves, chemical injection valves and other side pocket flow control devices which are not provided with integral latches.
- The Latch is installed and removed from the mandrel pocket using standard wire-line methods. A minimum amount of force is required to install the latch. This is particularly important in deviated wells where forceful downward jarring is not possible.
Retrievable Dummy Valve
- These BSP Wire-line Retrievable Dummy Valves are installed in side pocket mandrels as a non-equalizing isolation tool. The Dummy Valve is available in either stainless steel or nickel alloys for corrosion resistance in wells with high concentrations of H2S or CO 2. Packing for the valve is available for standard service or special service to suit individual well conditions. The distance between the packing stacks is maximized to fully protect the mandrel pocket seal bores from produced fluids until they are removed from the completion. The simple design of the dummy valve allows for easy replacement of the packing. The rugged, solid construction and quality materials provide for a long service life. The BSP retrievable dummy valve is used to bank off a side pocket mandrel ports to:
- Allow for production prior to the installation of gas lift valves.
- Blank off the side pocket prior to pressurizing the tubing to set a hydraulic set packer.
- Isolate the tubing flow from casing annulus for test purposes.
- Isolate tubing from casing annulus during remedial work such as acidizing or fracturing.
Retrievable Chemical Injection Valve
The BSP wire-line retrievable chemical injection valves are installed in a side pocket mandrels to control the injection of treatment fluids down-hole to control corrosion, harmful deposits or control hydrates in completions. The valve can be used in annular or injection control line application. Treatment fluids can be pumped through the valve continuously or intermittently. The valve is designed with a power spring which provides the closing force of the valve. The spring controlled test rack opening pressure is easily adjusted from outside of the valve without the need of disassembly. The spring loaded operation of the chemical injection valve allows accurate functioning of the valve regardless of well temperature.
