Tagging and tracking oil-gas mixtures in multiphase pipelines

چکیده
Pipeline transportation of multiphase products, such as gas and oil mixtures, exhibits complex varying flow regimes: a result, analytical approaches or conventional methods cannot accurately describe the composition propagation characteristics fluid mix inside system itself. We address an issue by presenting methodology, driven data applied to real case history, where basic pressure transients are used tag track, along pipeline, different batches medium. Several statistical indicators, computed from on window lengths, employed train machine learning model, which learns distinguish characteristic behavior two oil-gas slugs: in practice, each combination phases (in terms gas/oil ratio given batch product) sequence slugs variability between successive batches) behaves like coded linked flowing fluid. The key innovation consists possibility tracking flowline at monitoring station: this allows one determine real-time entering/exiting line, its position, movement pipe. As such, we obtain also virtual metering system, able provide estimates rate ratio. Moreover, having several recording stations synchronized, can leverage transmission multichannel processing data, enabling opportunity for online applications. results test cases accuracy scores obtained metrics considered validate tagging approach. • Pressure be track oil/gas slugs. pipeline virtually monitored. position traced real-time.

متن کاملHelical-contact Deformation Measuring method in Oil-gas pipelines
With the rapid increase in oil and gas consumption in the world’s energy consumption structure, the pace of global oil–gas pipeline construction has accelerated. Pipeline accidents that cause huge economic losses occur frequently, so inspection and maintenance of oil and gas pipelines have become critical issues. This paper presents a helical-contact deformation measuring method based on a mult...
متن کاملTowards the Formal Reliability Analysis of Oil and Gas Pipelines
It is customary to assess the reliability of underground oil and gas pipelines in the presence of excessive loading and corrosion effects to ensure a leak-free transport of hazardous materials. The main idea behind this reliability analysis is to model the given pipeline system as a Reliability Block Diagram (RBD) of segments such that the reliability of an individual pipeline segment can be re...
