LOCK MANDRELS
Novomet uses both selective and no-go profile lock mandrels to provide a setting point within the tubing for flow-control equipment. Designed for landing in profiled seating nipples, lock mandrel assemblies are used as a carrier for tools being deployed in the well, such as downhole chokes, pressure temperature gauges, isolation tools, plugging devices, check valves, and straddle systems. The locking assembly locates and locks the mandrel with the appropriate flow-control device to adjust flow up or down the tubing string while the well is in operation. Selective and no-go lock mandrels can be run and set under pressure on a wireline assembly.
BENEFITS
Easy, fail-safe operation eliminates workovers
Sets flow control at desired depth for continuous flow, even under high pressure
The assembly selects preferred seating depth according to the running tool being used, then locates and locks the mandrel
applications
- Wells using subsurface tools, including wireline and slickline operations
- Well plugging
- High-pressure installations
capabilites
- Sizes match all Novomet landing nipple sizes
- Multiple profiles and sizes available
features
- The lock assembly passes through multiple seating profiles with the same inside diameter (ID) and seats in the desired location
- Flow-through capability enables use as a gauge hanger or with a downhole choke to maintain well flow after being set
