Embodiment Construction

[0020] In the following specification and claims, reference will be made to a number of terms which shall be defined to have the following meanings.

[0021] The singular forms "a", "an" and "the" include plural referents unless the context clearly dictates otherwise.

[0022] "Optional" or "optionally" means that the subsequently described event or circumstance may or may not occur, and that the description includes instances where the event occurs and instances where it does not.

[0023] As described throughout the specification and claims, any number of expressions may be modified by approximating language which may vary without resulting in a change in the essential function to which it is related. Accordingly, a value modified by a term or terms, such as "about," "approximately," and "substantially," is not to be limited to the precise value specified. In at least some cases, the approximation may correspond to the precision of the instrument used to measure the value. ...

Abstract

A leak identification system for a blowout preventer (BOP) system is provided. The leak identification system includes a plurality of sensors configured to monitor one or more conditions of the BOP system and a leak detection computer device. The leak detection computer device is configured to receive at least one pressure measurement from at least one pressure sensor, receive at least one flow rate measurement from at least one flow sensor, compare the at least one pressure measurement and the at least one flow rate measurement to an algorithm, determining a leak in the BOP system based on the comparison, determine an impact to the operation of the BOP system based on the comparison and transmit the impact to the operation of the BOP system based on the comparison to a user.

Description

Background technique [0001] The field of the disclosure relates generally to the operation of blowout preventer (BOP) systems for oil and gas wells, and more particularly to systems and methods for detecting and locating leaks in BOP systems. [0002] Many known oil and gas production systems include subsea blowout preventer (BOP) systems that, after a period of operation, develop leaks that require repair. Such leaks are primarily caused by the harsh operating conditions in which such equipment is exposed, such as high pressure, high temperature, and / or corrosive environments that exist near or within the production system. [0003] Leakage in a BOP system is a significant means of reducing the operability and service life of a BOP system. This often results in stopping drilling operations to repair the BOP. In some cases, repairs required raising the BOP to the surface in order to locate and repair the leaking component, which resulted in significant downtime. In many kno...
