Flow Control
Equipment
Engineered for precise downhole fluid regulation, selective reservoir access, and dependable containment in high-differential pressure environments.
Landing Nipples & Lock Mandrels
Precision-machined internal locating profiles and matching lock mandrels engineered for high-pressure downhole plug, valve, and instrument seating.
Lock Mandrel (X Profile)
Selective locking mandrel designed for standard-weight tubing strings. Lands securely in matched selective nipples anywhere in the wellbore profile.
- ProfileSelective 'X'
- Tubing ClassStandard Weight
- Lock TypeExpanding Keys
- ConveyanceWireline / Slickline
Lock Mandrel (XN Profile)
Bottom-no-go locking mandrel for bottom-string applications. Positive seating shoulder prevents tool passage and resists high downward pressure differentials.
- ProfileNo-Go 'XN'
- PlacementTailpipe / Sump
- ShoulderPositive No-Go
- ConveyanceWireline / Slickline
Lock Mandrel (R Profile)
Heavy-duty selective lock mandrel engineered for heavy-wall tubing strings and severe-service, high-pressure gas and oil production wells.
- ProfileSelective 'R'
- Tubing ClassHeavy Wall
- Lock TypeExpanding Keys
- ConveyanceWireline / Slickline
Lock Mandrel (RN Profile)
Bottom-no-go mandrel matching heavy-wall tubing profiles. Combines a calibrated mechanical landing stop with high differential seal integrity.
- ProfileNo-Go 'RN'
- Tubing ClassHeavy Wall
- ShoulderPositive No-Go
- ConveyanceWireline / Slickline
Landing Nipple (X Profile)
Full-opening selective nipple placed throughout the tubing string. Allows unlimited non-matching wireline tools to pass freely until selected by key profile.
- TypeSelective Non-Restricting
- ProfileIndustry-Standard 'X'
- BoreFull Drift Bore
- Seal AreaHoned Seal Section
Landing Nipple (XN Profile)
Bottom-set nipple with an integral no-go shoulder restriction. Acts as the deepest landing station in the production string for positive barrier placement.
- TypeBottom No-Go Restriction
- ProfileMatched 'XN' Key
- PositionTailpipe Sump
- PressureBi-Directional Rated
Landing Nipple (R Profile)
Heavy-wall selective landing nipple. Provides multiple depth-isolation options for high-rate completions without restricting production flow area.
- TypeHeavy-Wall Selective
- ProfileStandard 'R' System
- PressureHigh-Pressure Wells
- ApplicationZonal Production / Test
Landing Nipple (RN Profile)
Bottom-set no-go landing nipple for heavy-wall tubing strings. Precision-bored to capture RN mandrels under extreme pressure differentials.
- TypeHeavy-Wall Bottom No-Go
- Profile'RN' Internal Step
- SealingPrecision Micro-Honed
- ServiceStandard / Sour (H2S)
Flow Control Equipment
Wireline running, pulling, and shifting tools alongside sliding sleeves and equalizing valves for safe mechanical well intervention.
X Line Running Tool
Intervention tool engineered to run and mechanically set X and XN profile lock mandrels into their respective landing nipples on slickline.
- FunctionSet Lock Mandrels
- ProfilesX & XN Systems

- Internal SleeveHoned Seal Section
- ShiftingMechanical B-Tool
- Seal IntegrityNon-Elastomeric Backup
SB Pulling Tool
Jar-down release wireline pulling tool designed to engage external fishing necks of downhole flow controls, chokes, and subsurface safety assemblies.
- EngagementExternal Fishing Neck
- ReachShort Core Design
- Release ModeDownward Jar Action
- ColletPrecision Spring Dogs
R Running Tool
Heavy-service wireline running tool engineered specifically for deploying and locking R and RN mandrels into matched heavy-wall landing nipples.
- FunctionSet Heavy-Wall Mandrels
- ProfilesR & RN Series
- Release MechanismShear Pin / Jar Action
- ConveyanceSlickline / E-Line
GS Pulling Tool
Industry-standard internal-catch pulling tool. Engages internal fish necks and retrieves flow-control devices, shifting to release via jar-down action if unseating stalls.
- EngagementInternal Fishing Neck
- OperationPull / Retrieve
- Release ModeDownward Jar Shear
- ConstructionHeat-Treated Alloy
Equalizing Prong Assembly
Used to equalize differential pressure across subsurface bridge plugs and check valves before retrieval, preventing explosive decompression and tool damage.
- PurposePressure Equalization
- ProfileMatches Standing Valves
- SafetyAnti-Blowout Stem
- ConveyanceWireline / Slickline
Equalizing Check Valve
Provides a one-way fluid barrier inside the production string. Holds formation pressure from below while permitting pumping down through the tubing from surface.
- Valve ActionOne-Way Non-Return
- Seat DesignElastomer-to-Metal
- EqualizationIntegrated Sub-Assembly
- MountingMatched Lock Mandrel
B Shifting Tool
Mechanical wireline shifting device used to open or close sliding sleeves downhole. Features self-releasing spring keys to prevent getting stuck in tight wellbores.
- TargetSliding Sleeves (SSD)
- ActionUpward / Downward Shift
- SafetyAutomatic Overload Release
