Abstract

A method for controlling a subsea valve assembly includes connecting a subsea riser between a wellhead and a surface vessel. An in-riser control unit is attached to a wired pipe string and disposed within the subsea riser, resulting in the in-riser control unit being deployed in-riser. The wired pipe string is connected to a surface control unit and a communication signal is transmitted through the wired pipe string between the surface control unit and the in-riser control unit to control the subsea valve assembly.

Description

USE OF WIRED TUBULARS FOR COMMUNICATIONS / ENERGY IN AN APPLICATION IN OUTLET PIPES CROSS REFERENCE TO RELATED REQUESTS The present application claims the benefit of US Provisional Application 61 / 355,439, filed on June 16, 2010.
ANTECEDENTS OF THE DESCRIPTION A typical subsea drilling production system has a wellhead and an underground valve assembly, such as a blowout preventer ("BOP") or a connection tree, installed therein. An outlet tube extends from the connection shaft, and together with the shaft and the mouth of the well, forms a gap. Various components of the drilling, such as a chuck for pumping pipe, a tool for running pipe, and a test shaft, are positioned in the hole and must be operated to perform their corresponding function. In conventional subsea drilling production systems, these components are hydraulically driven through passages, which extend upwards into the recess towards the surface. The hole may be housed within an outlet pipe that extends from a surface vessel to the bottom of the sea. A fluid reservoir and a pump on the surface provide hydraulic pressure to the components.
Conventional systems need long hydraulic umbilical lines to pass from the surface to the bottom of the sea. The deeper the submarine gap, the longer the umbilical lines must be, and the more flexion is introduced into the hydraulic system as the lines flex from the hydraulic pressure. This bending reduces the precision at which the components can be operated. Also, there is a large distance between the regulating pump and the component that is being operated, which increases the response times to operate the components. In some cases, because the fluid in the long umbilical lines must travel a great distance, these fluids are easily contaminated.
COMPENDIUM In general, in one or more embodiments, the invention relates to a method for controlling an underwater valve assembly, comprising connecting an underwater outlet pipe between a wellhead and a surface vessel; joining a control unit in the outlet pipe with a column of wired pipes; placing the column of wired pipes inside the submarine outlet pipe, causing the control unit in the outlet pipe to deploy in the outlet pipe; connect the column of wired pipes to a surface control unit; transmit, through the column of wired pipes, a communication signal between the surface control unit and the control unit in the outlet pipe to control the underwater valve assembly.
In general, in one or more embodiments, the invention relates to a control system for an underwater valve assembly, said system comprises an underwater outlet pipe connected between a wellhead and a ship, a regulator placed in a column of wired pipes where the column of wired pipes is placed in the submarine outlet pipe and configured to control the underwater valve assembly, a surface control unit placed on the ship and configured to communicate with the regulator through the pipe column wired.
