International Classification:

E21B 36/04

US Classification:

166302, 1662721

Abstract:

A method of heating a subsurface hydrocarbon containing formation includes providing heat flux per volume to a first portion of a subsurface hydrocarbon containing formation. The heat flux per volume is provided by two or more first heat sources positioned in the first portion. Heat flux per volume is provided to a second portion of the subsurface hydrocarbon containing formation with the heat flux per volume being provided by two or more second heat sources positioned in the second portion. The heat flux per volume provided by the two or more second heat sources is greater than the heat flux per volume provided by the two or more first heat sources. The second portion is positioned below the first portion.

International Classification:

E21B 43/01

Abstract:

A method of conveying a production fluid from an offshore subsea well to an offshore vessel includes deploying an inflatable bladder from the offshore vessel, the inflatable bladder including a bladder valve, and fluidly connecting the inflatable bladder to an offloading port positioned at a seafloor, wherein the offloading port includes a port valve and is in fluid communication with one or more subterranean hydrocarbon-bearing formations. The method further includes opening the bladder and port valves to discharge the production fluid from the offloading port into the inflatable bladder, and thereby resulting in a substantially filled bladder, closing the bladder and port valves, and fluidly disconnecting the substantially filled bladder from the offloading port.

International Classification:

E21B 47/14
E21B 47/00

Abstract:

A system for monitoring a line comprising a line, such as a mooring line, umbilical, pipeline, or riser. connected to an offshore structure including a control processor located on the offshore structure, a wireless network comprising a plurality of communication nodes positioned along the line, and a plurality of measurement devices embedded within the communication nodes. When the line is being monitored, the output of each of the measurement devices is in continuous wireless communication with the wireless network via at least one of the communication nodes positioned along the line and the wireless network is in continuous communication with the control processor.

B01D 17/12

Abstract:

The present techniques are directed to a multiphase separation system. The system includes a liquid-liquid separator configured to receive a separated liquid that is further separated into a separated oil and a separated water within the liquid-liquid separator (). An oil pump () and a water pump (), both with adjustable speeds, are configured to pump the separated oil and the separated water, respectively, from the liquid-liquid separator (). An interface level () in the liquid-liquid separator () is regulated by adjusting the speed of the oil pump () and the speed of the water pump ().

International Classification:

E02B 17/06
E02B 17/08
E02B 17/02

Abstract:

A subsea system for installing, suspending and removing underwater equipment below the surface of the sea is provided. The subsea system includes a landing base module for landing and positioning underwater equipment thereupon, the landing base module comprising a base member and a first buoyancy system; and a second buoyancy system for affixing to the underwater equipment, the second buoyancy system having sufficient buoyancy to float the underwater equipment toward the surface of the sea when detached from the landing base module, wherein the underwater equipment includes a ballast system structured and arranged to permit the underwater equipment to be lowered onto the landing base module. A method for installing, suspending and removing underwater equipment below the surface of the sea and a kit of parts are also provided.

International Classification:

G01F 23/24

US Classification:

73295

Abstract:

Systems and methods for identifying the level of media in a vessel with a sensing cable including an optical fiber sensor array aligned with a heating element disposed in the vessel. An excitation source is configured to propagate at least one heat pulse through the heating element along at least a portion of the sensing cable to affect an exchange of thermal energy between the heating element and the one or more media exposed to the sensing cable. An optical signal interrogator is adapted to receive a signal from each of a plurality of sensor locations and measure a temperature profile corresponding to the heat pulse at the sensor locations. A control unit is configured to identify a level of each of media by determining properties of the media exposed to the sensing cable at each of the sensor locations based on the temperature profile corresponding thereto.
