System and method for secure downhole intelligent completions

摘要

A flow control apparatus for controlling fluid flow in a petroleum reservoir. The flow control apparatus has a flow control mechanism, a controller operable to control the flow control mechanism to adjust fluid flow through the flow control mechanism, the controller comprising a processor operable to execute according to a control algorithm, and a non-volatile memory connected to the controller. The non-volatile memory includes instructions to cause the controller to execute an authentication mechanism operable to authenticate a control computer and to prevent operation of the controller until the authentication mechanism authenticates the control computer.

1. An intelligent completions tool configured to be deployed downhole for controlling fluid flow in a petroleum reservoir, comprising:
an adjustable valve; random access memory; and nonvolatile memory including: a first portion of a control algorithm; and instructions that when executed by a processor, cause the processor to perform acts comprising:
receiving a digital certificate from a secure node geographically remote from the intelligent completions tool;authenticating the digital certificate associated with the secure node;accessing the first portion of the control algorithm;downloading, based on the authentication, a second portion of the control algorithm from the secure node; andcreating a control program by merging the first portion of the control algorithm with the second portion of the control algorithm in the random access memory;storing the control program in the random access memory; andexecuting the control program, wherein executing the control program comprises:
receiving, by the control program, one or more parameter values from the secure node; andadjusting, by the control program, the adjustable valve in response to the one or more parameter values.
