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.

Natural-gas-infrastructure reliability is critical for the energy sector. When capitalizing on old pipelines to transport natural gas, operators run the risk of partial blockage. In this study, the authors develop a multirate test method to detect partial blockage in a gas pipeline. -
Subsea tieback of a new field to an existing offshore production facility is one option to minimize development costs.

This paper describes a new direct electrical heating method in flexible-pipe systems. The method effectively expands the operational envelope of flexible unbonded pipes with greater control of hydrate plugs and wax precipitation by distributed heating along the entire pipe length,

Medium-voltage electric heating systems offer reduced installation cost and increasing efficiency for multimegawatt oil and gas heating applications compared with low-voltage systems. For offshore applications, the systems offer the added benefit of both space and weight reductions.

Thermoplastic composite pipe (TCP) is a spoolable, fully bonded pipe with glass or carbon-fiber reinforcements. While most often used in deep water, the combination of a solid wall, spoolability, and corrosion resistance makes TCP attractive for production-flowlines in shallow water also.

A presentation from the 2016 Gulf of Mexico Deepwater Technical Symposium examines a testing strategy to determine the effectiveness of paraffin inhibitors.
-
This paper presents a state-of-the-art review of scale-inhibitor-analysis techniques and describes how these techniques can be used to provide cost-effective scale management.

An experimental study was conducted by use of a 6-in.-inner-diameter facility to analyze three-phase stratified wavy flow in horizontal pipelines.
-
In trying to reduce the footprint of facilities, operators often select the wrong piping components, hampering the performance. Selection of the right piping can avoid separation issues.
-
Construction costs, contractor involvement, flow assurance, and the integration of new technologies created to improve production are some of the deepwater challenges exacerbated by the current low price environment.
