Flow assurance
This paper describes the successful deployment of flexible coiled tubing technology in an oil-producing well of the offshore Frade field in Brazil’s Campos Basin.
This case study from Italian technology developer Sentris highlights the effectiveness of using sensors during pigging operations to optimize cleaning efficiency.
The objective of this study is to field test a non-nuclear multiphase flowmeter and assess its performance under challenging operating conditions.

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.
-
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.
