Abstract
A technique facilitates use and installation of a large bore completion system. The technique comprises providing infrastructure during an initial completion stage and deploying a monitoring system. Based on data from the monitoring system, an intelligent completion may later be deployed as necessary to control production, injection, or other well related fluid flows.
Claims20
A method for installing a large bore completion system, comprising:
- providing real time monitoring of reservoir parameters in a well via a retrievable instrumented stinger;
- retrieving the retrievable instrumented stinger after determining a need for controlling flow;
- running a lower completion section comprising one or more valves and one or more sensors in hole;
- and
- controlling flow by manipulating one or more valves.
2 more elements
A system, comprising:
- a large bore completion system having a lower liner section disposed in a wellbore across at least one well zone;
- a retrievable instrument having at least one sensor to monitor a reservoir parameter in a well zone when the retrievable instrument is conveyed downhole through an interior of the lower liner section;
- a lower completion system which is run in hole to replace the retrievable instrument upon determining a need for controlling flow, the lower completion system having at least one sensor and at least one flow control valve to control flow;
- and
- a power source located downhole to provide power to the lower completion system.
2 more elements
A method of installing a large bore completion system, comprising:
- suspending a lower liner section downhole across a plurality of well zones;
- segregating well zones along the lower liner section with a plurality of controllable valves;
- monitoring a well parameter;
- and
- based on the monitoring, manipulating individual valves of the plurality of controllable valves to selectively block or limit flow at specific well zones along the plurality of well zones.
