US Patent 7346456: Wellbore diagnostic system and method

US 7346456  ยท  granted 2008-03-18

Abstract

To perform diagnosis of a completion system, at least one parameter of the completion system in a wellbore is monitored using a sensor. A profile is generated based on the monitored parameter, and a real-time diagnosis is performed of an operation of the completion system based on a comparison of the generated profile and an expected profile to identify an anomaly.

Abstract

To perform diagnosis of a completion system, at least one parameter of the completion system in a wellbore is monitored using a sensor. A profile is generated based on the monitored parameter, and a real-time diagnosis is performed of an operation of the completion system based on a comparison of the generated profile and an expected profile to identify an anomaly.

Claim 1

A method comprising: monitoring at least one parameter of a completion system in a wellbore using at least one sensor; generating a profile based on the monitored atleast one parameter; performing real-time diagnosis of an operation of the completion system based on a comparison of the generated profile and an expected profile to identify an anomaly; and creating the expected profile based on a test using a firsttype fluid, wherein performing the real-time diagnosis of the operation in the wellbore comprises performing real-time diagnosis of the operation in which a treatment is applied, the treatment containing a material not contained in the first-type fluid.
