Flow assurance
This paper describes a case history in the UAE in which the cleanout of scale contaminated with naturally occurring radioactive material was conducted successfully.
In the wake of the falling number of exploratory wells in the country, Brazil-owned Petrobras addressed audience concerns as well as outlined new avenues for production at the Offshore Technology Conference.
The authors of this paper describe a project to develop a virtual sensor to monitor the cooling effect downstream of a subsea choke to avoid hydrate plugs during cold-start operations.

The understanding of solid-particle flow regimes in pipelines for any operational conditions is important for identifying the nature of particle interaction and movement. In this paper, a comprehensive analysis of solid-particle flow regimes in stratified flow in a horizontal pipeline is presented. -
Replicating field conditions for flow assurance experiments at a reasonable cost often presents many challenges, particularly when it comes to designing an experiment with appropriately scaled geometry, an expert said.
-
When the underlying cause of flow-related issues on offshore projects is unknown, an expert said an investigation of fluid flow behavior based on an understanding of the first principles of flow assurance is necessary.

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.
