How it improves performance
The modular selective lateral intervention completion (SLIC) system enables thru-tubing interventions in multilateral wells. It can be used to access the lateral or hydraulically isolate it from the main bore.
How it works
Each SLIC system module is a tubular with a side opening, sealbores, and profiles for intervention tools. It uses standard tubing threads and is run in the well as part of the completion string. Multiple modules can be installed for selective intervention access when one well has multiple laterals.
Three intervention tools are available with the system:
- orienting selective locating tool (OSLT)
- lateral deflector
- isolation sleeve
Selective thru-tubing access
To access the lateral, the deflector tool is run in on CT or jointed pipe together with the OSLT, which provides orientation and latches the deflector in place inside the SLIC module. The deflector steers the intervention assembly into the lateral through the side opening of the SLIC system module.
Alternatively, the OSLT can be run together with the isolation sleeve, a tubular with external seals. When the sleeve is latched in place inside the SLIC system module, it seals in polished bores above and below the module’s side opening, providing pressure integrity up to 10,000 psi to seal off the lateral. Access to and production from the main bore is available through the sleeve ID.
