摘要:
The present invention relates to a subsea pipeline and method utilizing the pipeline wherein the loss of pipeline contents resulting from a break in the pipeline is reduced. The loss of pipeline contents is reduced by providing a plurality of traps in the pipeline. The traps each comprise at least two elevation changes in alternating directions. Any water entering the pipeline through a breach will only displace pipeline contents from the breach to the adjacent lower trap.

Vibrations are created in a flow conduit by constraining a bluff object having a plurality of positions between which flow of fluid forces the bluff object. In a preferred embodiment, the vibration technique is utilized in a gravel packing tool. Gravel pack sand is placed while the gravel pack tool is vibrated by balls constrained within a wash pipe. A considerably improved gravel pack density is achieved.

A fluid level control system comprising a structure containing oil and water; a fluid off-take located on said structure; flow controller fluidly connected to said fluid off-take; a sensor located on said structure and adapted to measure a property of said oil and said water; and a computer for interpreting a signal from said sensor.
摘要:
A system for assuring subsea hydrocarbon production flow in pipelines by chilling the hydrocarbon production flow in a heat exchanger and causing solids to form, periodically removing deposits and placing them in a slurry utilizing a closed loop pig launching and receiving systems.
摘要:
A method for monitoring fluid properties with a distributed sensor in a wellbore having an inner surface, a top and a bottom comprising causing the distributed sensor to assume a helical shape, pulling the distributed sensor towards the bottom of the wellbore, while retaining the helical shape of the distributed sensor, feeding the distributed sensor into the wellbore so that the distributed sensor is in substantially continuous contact with the inner surface, and allowing the distributed sensor to become at least partially supported by friction at the inner surface.
摘要:
A wash down placement of a screen into sand within a well borehole is improved by vibration of a wash pipe as the wash pipe is removed from the screen. A compacted sand gravel pack around the screen is achieved. The vibrations are created by constraining a bluff object having a plurality of positions between which flow of fluid forces the bluff object.

摘要:
A method for separating a multi-phase fluid, the fluid comprising a relatively high density component and a relatively low density component, the method comprising: introducing the fluid into a separation region; imparting a rotational movement into the multi-phase fluid; forming an outer annular region of rotating fluid within the separation region; and forming and maintaining a core of fluid in an inner region; wherein fluid entering the separation vessel is directed into the outer annular region; and the thickness of the outer annular region is such that the high density component is concentrated and substantially contained within this region, the low density component being concentrated in the rotating core.
