FlexRite® MIC Junctions Enable More Advanced Multilateral CompletionsDownload PDF
Enable more advanced completion solutions to provide MIC
North Sea, Norway
In the late 1990s, Halliburton partnered with a major North Sea operator to install multilateral technology (MLT) systems in Norway’s deepwater field. This collaboration led to the development of the first FlexRite® multilateral system in 2001, and its use on wells in many other fields.
Halliburton has recently completed its 300th FlexRite system installation for the operator. These installations have included all types of FlexRite junctions, including lateral access (LA), intelligent completion interface (ICI), and multibranch inflow control (MIC). In late 2018, the Halliburton MLT team in Norway celebrated a new milestone by installing its 100th FlexRite MIC system in the North Sea.
Back in 2012, the operator required a solution for achieving new levels of zonal control in its multilateral wells. Traditionally, many multilateral wells have consisted of multiple branches commingled in a completion solution that provides greatly increased reservoir exposure, but with limitations on control over individual branches and zones. A new completion solution was required that would address challenges such as water and/or gas breakthroughs in laterals, and allow for greater productivity and well life.
Halliburton worked with the operator to develop the FlexRite MIC system, which was the first TAML Level 5 junction of its kind to allow upper completion components to be run through the junction – thus representing a step change in the possibilities for advanced completion solutions.
The FlexRite MIC system allows a multilateral well to be completed with sand screens, swellable packers, inflow control devices (ICDs), and interval control valves (ICVs) to help increase reservoir exposure and maximize production from each multilateral leg. It allows individual branch control of stacked (three legs or more) multilateral wells, and a single-trip completion system consisting of multiple slim-hole ICVs can be deployed through stacked TAML Level 5 multilateral junctions. Using the FlexRite MIC system, an unlimited number of MIC junctions can be installed into a given well. Now, production or injection can be managed and controlled at each individual lateral totally independent of all other lateral legs.

The development of the FlexRite MIC system enabled selective control and monitoring of individual laterals. The new junction featured a large drift diameter throughout the entire mainbore, allowing for a single-trip final installation of an intelligent completion string. This, in turn, provided the ability to choke back individual branches, should they experience a gas influx or water breakthrough, without impacting the production from other laterals.
Since the first FlexRite MIC installation in 2012, this technology has grown and developed to become a standard solution for several fields in the North Sea. As of late 2018, Halliburton reached a new milestone in Norway by successfully installing the 100th FlexRite MIC junction. This system has proven its success through its solid track record and industry-leading reliability. Halliburton has installed over 100 of these systems in Norway over a period of six years, and it has become the system of choice for several fields in the North Sea.
