Flow assurance
For more than a century, LSU has shaped petroleum engineering education, but few assets showcase its impact like the PERTT Lab. With six deep test wells and rare reservoir-depth gas-injection capabilities, the facility is helping drive breakthroughs in well control, carbon-dioxide injection, and next-generation energy technologies.
Experience in subsurface production and lift design is shaping a new generation of geothermal operations built for reliability and scalability.
The research facility said it plans to add multiphase-flow-testing capabilities for heavy oil and different viscosities.

Rice University has been working on effective models of phase behavior and asphaltene deposition as a path to improved design that can reduce this challenge for operators. -
Riser slugging can restrict production and cause problems for downstream equipment. This paper discusses a simplified modeling approach to control of riser slugging.
-
Severe slugging is characterized by large pressure fluctuations at the base of the riser and is accompanied by fluctuations in fluid delivery from the top of the riser. This instability has negative effects on downstream equipment.

Flow assurance is a burgeoning field that offers many opportunities to young engineers—provided they are willing to develop expertise in a range of technical disciplines to obtain additional nontechnical skills.
-
Water condensation and/or hydrate formation at the top of pipelines are serious design/operation considerations in pipelines. This paper reports the results of tests conducted in a new experimental setup constructed for investigating gas-hydrate risks in varied operational scenarios.
-
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.
-
This paper illustrates a numerical approach to estimate the deposition profile of precipitated wax crystals and its effect on flow-related parameters in pipelines. Options for avoiding these issues are also explored.
-
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.
-
As the world's supply of crude becomes heavier, many of the world’s oil producers will have to think more carefully about heavy crudes and the challenges they pose for processing, storage, and transportation.
-
The effects of turbulence/shear and thermal driving force on wax-deposition characteristics were experimentally studied using a waxy crude oil from the Gulf of Mexico.
