Pipelines/flowlines/risers
The DeepOcean-lead joint industry project aims to advance commercialization of a new patented technology that heats pipeline systems deployed in deepwater where flow assurance can be a challenge.
BP’s new electric gas compression platform at Shah Deniz, Azerbaijan’s largest natural gas producer, is expected to sustain exports to Europe even as the field enters decline.
Nitzana will enable Israel to double gas exports to Egypt from the giant Leviathan gas field in the Eastern Mediterranean.

This paper evaluates the feasibility of a number of production- and export-riser configurations for ultradeepwater applications. -
This paper presents a multirate-test method to detect locations and sizes of blockages in gas pipelines.
-
An experimental study was conducted by use of a 6-in.-inner-diameter facility to analyze three-phase stratified wavy flow in horizontal pipelines.
-
Deepwater production has become more reliant on the integrity of subsea, umbilical, riser, and flowline (SURF) systems. A JIP explored cost-effective inspection and maintenance options.
-
This paper presents the challenges and obstacles faced in the use of a new technology for the plugging and deoiling of sections of unpiggable flowlines before decommissioning.
-
Bypass pigging has advantages over conventional approaches. Its application to multi-phase flow with high wax content crude is discussed.
-
Active slug-control methods have been developed in recent years. One such system is a relatively inexpensive solution developed by Shell that has proved to be very effective in stabilizing slugging in flowlines and risers.
-
Projects are being delayed or deferred due to low oil prices, which is affecting the market for subsea, umbilicals, risers, and flowlines (SURF).
-
More precise measurement can create a dilemma. One example is the precise fluid flow measurements used to control managed pressure drilling (MPD) systems.
-
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.
