Benefits of technology

The patent describes a system for drilling and producing oil from a well. The system includes a through tubing completion system that is run in a lateral borehole. This system includes production tubing, a flow control valve, and sensors to measure characteristics of the well. It also includes a male or female wet connect system to control the flow control valve and communicate with the sensors. Additionally, the system includes a wireless communication module that can communicate with a surface location while coupled to the through tubing completion system. This allows for wireless communication across gaps using a coil arrangement. The patent also describes a method for installing the through tubing completion system with the connection system. The technical effects of this patent include improved well monitoring and control, improved wellbore stability, and improved wellbore safety.

Problems solved by technology

With this type of well construction, there are challenges with respect to completing these new drainage points due to the constraints posed by the existing upper completion sections.
Additionally, another challenge is communicating with the through tubing completion in order to achieve selective control and data measurement.

Abstract

A technique facilitates use of a through tubing completion system run in a lateral borehole. The through tubing completion may comprise production tubing coupled to a flow control valve and one or more sensors measuring at least one characteristic of the lateral borehole. The through tubing completion also comprises a connection system which facilitates the transfer of signals between the through tubing completion extending into the lateral borehole and a surface location or other location.
