Greedy Pursuit: Algorithms Show Promise in Measuring Multiphase Flow
“Greedy pursuit” in the realm of algorithms is a good thing. Saudi Aramco studied such algorithms to produce images simulating the flow inside a pipe’s cross section, possibly reducing the need for separator-based multiphase flowmeters.
Past Experience Drives Petrobras Flow Assurance Strategy
A former technical manager with Petrobras discusses the development of the company’s flow assurance philosophies and strategies.
Pressure-Minimization Method for Prediction of Two-Phase-Flow Splitting
Looped lines are used to reduce pressure drop and increase flow capacity, but information on the flow behavior or predictive methods are not available for these systems.
Effectiveness of Bypass-Pigging Solutions in Multiphase-Flow Pipelines With Waxy Crude Oil: Evaluation and Innovative Solution
Bypass pigging has advantages over conventional approaches. Its application to multi-phase flow with high wax content crude is discussed.
PFC Lecture Series Covers Meter Selection and Applications
The SPE Gulf Coast Section’s Projects, Facilities, and Construction study group presented sessions during its spring lecture series on experts’ discussions of the processes involved in metering measurements.
Flow Assurance -Hydrates and Paraffin Management
As environments become more challenging, the importance and complexity of flow assurance has evolved. To effectively manage flow assurance, oil and gas operators must take a holistic approach, particularly when working in deepwater offshore environments.
Defoamer Improves Flow, But Effect Is Temporary
A relatively small concentration of a defoamer can have a significant impact on the dynamics of multiphase flow within a pipe, but the effect is generally temporary.
Simulation of Multiphase Fluid-Hammer Effects During Well Startup and Shut-in
In this study, software that is capable of modeling fully transient multiphase flow in wellbore and pipeline has been used to characterize the fluid-hammer effects of well shut-in and startup on the coupled subsurface and surface systems.
Comparison of Multiphase Pumping Technologies for Subsea and Downhole Applications
The selection criteria for multiphase boosting options remain somewhat subjective. A comprehensive literature review into the working principles of the major pump types identified the intrinsic advantages and limitations of each technology for subsea and downhole applications.
