Estimation approach for use with a virtual flow meter

Approaches for a modeling and estimation approach for a virtual flow meter (VFM) are described. Certain aspects of the present virtual flow meter approaches relate to the manner in which multiple sources of information in the field are merged within …

System and method for identifying and recovering from a temporary sensor failure

A sensor system for identifying a transient sensor failure in an industrial system and for recovering from an erroneous estimation of an expected mass flow rate resulting from the transient sensor failure. The sensor system includes one or more …

Modeling framework for virtual flow metering for oil and gas applications

A method of operating a hydrocarbon extraction field with the aid of a computer includes programming the computer with a virtual flow meter model. The model may be written with a notation that represents at least one of mass flow, temperature and …
