Many systems with new features and improved functionality have been introduced which have enhanced the success and growth of multilateral technology. The MACH-3™ system is among the latest of these offerings. This innovative hybrid system is an example of RMLS™ technology that has been re-designed to provide a simpler and faster method of completing TAML Level 3 multilateral junctions. This system will greatly reduce the amount of rig time required for multilateral junction construction by simplifying the installation process and minimizing the number of trips to complete. It also provides increased functionality with large diameter, selective re-entry access to either the lateral or main well bore. Primarily designed for heavy oil applications where the cost of installation is a major issue, the system has potentially far reaching applications in this and other markets.The paper describes the mechanical and operational principles of the system in its potential applications. The basic functionality of the MACH-3™ system will be analyzed, and some simple guidelines and limitations will be put forward for the selection of a Level 3 multilateral system. These guidelines are based on some of the lessons learned from multilateral experience in Canada, Venezuela and the U. S. A.IntroductionWith the continuing advancement of multilateral technology, operators are beginning to demand more specialized multilateral systems to suit particular reservoir development applications. Multilateral wells are now being used to recover hydrocarbons in a wide variety of different reservoirs and geographic locations. Heavy oil producers, require multilateral technology to maximize their reservoir exposure on a per well basis. However, the system design must be operationally simple in order to be economic in many of these shallow, low pressured, heavy oil developments.In an effort to lower risk and maximize returns in heavy oil applications, Halliburton's Sperry-Sun Multilateral Technology group has developed a TAML Level 3 system that is a simplified, yet improved version of the traditional TAML Level 4 RMLS™ (Retrievable Multi-Lateral System) junction. It is simpler than a Level 4 to install, and it has increased strength over a Level 2 junction providing to the longevity of the lateral well bore.The MACH-3™ (Mechanically Attached Casing Hang-off) system constructs a Level 3 junction that physically "locks" the lateral liner into the main bore casing to provide junction strength with a minimal restriction of access to the lower main bore. The system has potential applications in the recovery of medium and light oil, as well as in low pressured gas reservoirs. The reduced installation time also makes the system practical for offshore multilateral wells, where the expensive rig costs of performing multilateral operations can be significantly reduced. While being specially suited for heavy oil developments, the MACH-3™ system can be applied to a variety of different reservoirs requiring a TAML Level 3 solution.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
