Mitigating Gas in Riser Rapid Unloading for Deepwater Dual-Gradient Well Control
A study using a dynamic multiphase-flow software simulated a rapid-unloading event and determined the gas fraction in the riser annulus and the effect on riser fluid levels.
Qualification of Composite Pipe
This paper describes the qualification process for a thermoplastic composite pipe manufactured for use in high-performance riser, jumper-spool, and intervention-line applications.
Direct Electrical Heating of a Flexible Pipe
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,
Thermoplastic-Composite-Pipe Flowline Helps Reduce Project and Life-Cycle Costs
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.
Riser-System Design in Water Depths Greater Than 3000 m
This paper evaluates the feasibility of a number of production- and export-riser configurations for ultradeepwater applications.
A New Method To Detect Blockage in Gas Pipelines
This paper presents a multirate-test method to detect locations and sizes of blockages in gas pipelines.
Miniaturized Coiled-Tubing System Reduces Costs During Pipeline Decommissioning
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.
Increasing Production by Applying Active Slug-Suppression Technology
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.
