Flow assurance
This paper explains that the discovery of specific pressure trends, combined with an unconventional approach for analyzing gas compositional data, enables the detection and prediction of paraffin deposition at pad level and in the gathering system.
This paper presents an approach to subsea hydrate-risk management based on the understanding that some crudes have induction properties that delay hydrate formation even when the pressure and temperature conditions reach the hydrate thermodynamic region.
This paper discusses a comprehensive hybrid approach that combines machine learning with a physics-based risk-prediction model to detect and prevent the formation of hydrates in flowlines and separators.

Use of surfactants and gas lift in combination to suppress severe slugging were tested. Surfactants were able to suppress severe slugging for most of the cases, and gas lift helped significantly. -
The Tamar deepwater gas development offshore Israel experienced a short 4-year gap between discovery and startup, but doing so required the tough decisions in handling significant flow assurance issues.
-
Flow assurance issues offshore fall into three main categories -- production chemistry (deposition), operational issues (sand, slugging, foaming, emulsions) and integrity (corrosion, erosion)

When energy and healthcare collaborate, innovation is born. Pumps and Pipes, an unprecedented cross-industry collaboration between oil and gas exploration and production (E&P), cardiovascular medicine, aerospace, and academia, has grown into an international forum for transferable ideas and technolo

For many projects, asphaltene management plans are a matter of remediation or prevention. In the past decade, models have been developed to predict how asphaltene particles will behave in oil—the conditions under which precipitation and agglomeration occur.
-
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.
