... that rigorously quantify flow rates using DAS. This work expands the existing literature by presenting a detailed workflow for accurately estimating fluid flow rates from DAS data using time- and frequency-domain signal processing. Three simple empirical correlation functions (linear, exponential, and cubic...

... includes a set of multiphase flow correlations. The MILP estimates the flow rate and designates the best-fit model. The VFM is evaluated against 649 well test data. The methodology presents a 4.1% absolute percentage error (APE) for the 25th percentile and 13.5% APE for the 50th percentile of the data...

...M. G. Ramirez; D. O. A. Cruz; F. Nikfarjam; H. R. Anbarlooei Summary Mechanistic slug models generally depend on several empirical correlations. This work presents an extended model, which incorporates a recently theoretically developed family of friction equations for purely viscous non-Newtonian...

... capacity of mesh pads. Pressure drop and capacity models for mesh pads are presented and compared with literature experimental data for fluid systems ranging from atmospheric pressure to 85-bar natural gas. The experimental data were successfully correlated from the region of countercurrent flow through...

Other models correlate H LS with different flow variables, resulting in an iterative solution for predicting these transitions. Using an experimental database collected from the open literature, two empirical...

A brief review of the conventional approaches, along with their advantages and shortcomings, are provided in this section. Correlations can be performed in one of two ways, either using...

...Abdelsalam Al-Sarkhi; Khalid Abdelbasit; Haitham Bahaidarah Summary Pressure drop prediction of high‐viscosity oil/gas flow is an important issue in several industries, and it has a great interest for many researchers. This paper presents a simplified correlation for two‐phase high‐viscosity oil...

The highly heterogeneous carbonate rock samples contain several types of insoluble minerals such as quartz and various types of clays along sealed natural fractures. These minerals are distributed in the form of streaks correlated...

Our model is verified by comparing the simulation results with the experimental data of liquid CO 2 and correlations developed for water‐based fluid. It is confirmed that the friction loss of CO 2 follows the phenomenological Darcy‐Weisbach equation, regardless...
