Instrumentación para sistemas automatizados de medición dinámica de hidrocarburos

Abstract

Introduction: The article establishes a conceptual review on the instrumentation used in automatic oil and gas measurement systems, carried out by the Orca and SciBas research groups at the Universidad Distrital Francisco José de Caldas in 2017. Problem: Absence in the literature of the concept of custody transfer (CT) and its impact on the quantity and quality of gas and oil in a distribution system. Aim: To conceptualize about instrumentation in high volume measurements, particularly those of dynamic type. Methods: Selection, prioritization and interpretation of sources available in the industrial sector—covered by the American Petroleum Institute (API) and the American Gas Association (AGA)—to define the instrumentation of a reliable and accurate gas and oil measurement system. Results: Conceptualization of API and AGA units with respect to LACT (Lease Automatic Custody Transfer) equipment, of criteria for determining the instrumentation for CT systems, and of measurement equipment in instrumentation distribution. Conclusion: Obtaining of a conceptual baseline on CT problems and their instrumentation in an automatic gas and oil dynamic measurement system. Originality: The academic literature contains little reference to reviews on equipment and instrumentation used in automatic systems for oil and gas CT. Limitations: Since flowmeters are the most important instruments of the metering skid with respect to those reviewed, other flowmeters that use adaptive measurement algorithms such as neural networks (NN) should be included—in perspective—.
