METHOD FOR CHECKING PERFORMANCE OF LOWER COMPLETION COMMUNICATION SYSTEM Russian patent published in 2018 - IPC E21B47/12 

FIELD: soil or rock drilling; mining.

SUBSTANCE: invention relates to means of monitoring the performance of a well completion system. In particular, a system is disclosed for verification of the operation parameters of an arrangement for lower completion, comprising: a lower completion deployed in the wellbore prior to the deployment of the upper completion, the lower completion arrangement comprising a sensor, a communication system, and a flow control system; and a service tool system removably deployed in the wellbore, wherein the service tool system comprises a service tool system interface interacting with the lower completion arrangement prior to connecting the upper completion arrangement with the lower completion arrangement. Service tool system interacting with the lower completion arrangement serves to verify the operating parameters of at least one sensor, communication system and flow control system without a communication line, laid separately to the lower completion arrangement and prior to deploying the upper completion arrangement.

EFFECT: disclosed invention enables to verify performance of various components for the lower completion arrangement without the use of an additional communication line, such as a power cable, laid separately for this arrangement.
