RapidAccess

Self-orienting TAML 2 multilateral junction system

Applications

  • Wells with TAML 2 specifications
  • Reservoirs with the same pressure and flow regimes
  • Layered, compartmentalized, or faulted reservoirs
  • Reservoirs needing increased drainage
  • New oil or gas producers or injection wells
  • Directional perforating and optical fiber installation

Benefits

  • Reduced risks, time, and costs due to operational simplicity and field-proven technology
  • Reliability and high rate of success

Features

  • Selective reentry into all laterals and main bore with wireline, coiled tubing, or drillpipe access
  • Facility to stack multiple TAML 2 junctions in a single wellbore
  • Unlimited lateral sections, allowing as many indexing casing couplings as required
  • Permanent depth and orientation point retained (via the indexing casing coupling) without compromise to casing ID
  • Fullbore access to the main bore and lateral
  • Compatibility with intelligent completions, including Electris™ completions
  • Compatibility with the SLB selective lateral intervention completion (SLIC) system for thru-tubing interventions in multilateral wells

How it improves performance

The indexing casing couplings of the RapidAccess™ self-orienting TAML 2 multilateral junction system provide selective access and multiple kickoff points for current and future sidetracks and multilateral wellbores. This highly reliable system is based on a self-orienting and locking casing nipple concept. It can be easily accommodated in any TAML 2 application in new wells with standard oilfield practices and tools.

How it works

The system comprises

  • indexing casing coupling (ICC)
  • construction selective landing tool (CSLT)
  • construction reentry deflection tool (CRDT).

The ICCs are installed in the casing string when it is run, and they are reusable throughout the life of the well. After they are installed, ICCs become integral casing components and enable future reentry operations without compromising the integrity of the casing string. Orientation is determined by using standard logging tools or MWD in gravity toolface mode. The CSLT and CRDT are then adjusted at surface to enable construction of the lateral in the direction required.

These ICCs as well as the CSLT and CRDT are also used with TAML 3 and 4 Rapid™ multilateral junction systems to enable lateral access.
