  • Publication number: 20230143172
    Abstract: The present invention relates to shallow water subsea desalination system with a subsea desalination template (20) located on a seabed. A retrievable subsea RO-module (4) is located in a subsea RO-module zone (23) of the subsea desalination template (20) and is connected to a RO-module connection. A seawater booster pump assembly (1) includes a seawater inlet (7) and an outlet in fluid connection with a seawater inlet side of the RO-cartridge assembly. A retrievable subsea booster module (2) includes the seawater booster pump assembly (1). A pressure regulator (11) is in fluid connection with a retentate side of the least one retrievable subsea RO-module (4).

  • Publication number: 20210220775
    Abstract: A subsea desalination template includes subsea desalination module zones and module fluid couplings. A desalinated water outlet is in fluid connection with the module fluid coupling in the subsea desalination module zone. Subsea desalination modules with reverse osmosis cartridges are in fluid connection with a subsea template fluid coupling, a seawater inlet section, and a concentrated seawater outlet section. A transport pump assembly for desalinated water in a pump module is in fluid connection with the subsea desalination template and the desalination modules. A seawater circulation pump is in fluid connection with a seawater side of the at least one reverse osmosis cartridge. A desalinated water pipeline conveys fluid from the desalinated water transport pump assembly to a location above sea level.

  • Publication number: 20090065431
    Abstract: An in-line separator is provided for separating fluid phases of different density from a fluid stream. The in-line separator comprises a conduit having an inlet section (2) for receiving the fluid stream, an outlet section (12) for separately transporting the fluid phases, and a swirl section (4) for inducing a swirling motion to the fluid stream as the stream flows from the inlet section (2) to the outlet section (12), the swirl section having an interior space (19a). At least a portion of said interior space forms a passageway (19a) for passage of tools from the inlet section (2) to the outlet section (12).

  • Publication number: 20080237140
    Abstract: A fluid phase distribution adjuster (10) comprises two or more tubes (14) arranged to provide a plurality of separate flow paths for fluid. Means are provided for generating a radial acceleration of fluid flowing through each tube so as to promote movement of at least one fluid phase towards or away from a wall of the tube. The adjuster can be used as a coalescer for increasing the size of droplets in a distributed fluid phase carried by a continuous fluid phase, or as a mixer for mixing fluid phases.

  • Patent number: 6688180
    Abstract: A multi-test assembly for evaluating, detecting and monitoring processes at elevated pressure is described. The Mufti-test assembly has a pressure vessel equipped with trays or plates with a multitude of individual test cells, an optional lid for sealing the cells, and a system for the detection and/or monitoring of the processes in each individual test cell, in situ. Uses of the invention are detection of solid structure formation or phase transformation in, for example, hydrocarbon systems or mixtures of hydrocarbon and water, and also in an automated test which is optimized simultaneously with regard to several test parameters in the testing of inhibitors for gas hydrate formation. The multi-test assembly has built-in systems for pressure and temperature control. The assembly may also be connected to a set-up for the automatic dosing of reagents.

  • Patent number: 6672385
    Abstract: The invention relates to a system and a method for well completion, control and monitoring of processes in a reservoir. A combined prefabricated liner and matrix system (4) with defined properties for fast and simple well and/or reservoir completion, monitoring and control is provided. An embodiment of the combined prefabricated liner and matrix system 4 includes an outer perforated tubular pipe system 6, an inner tubular screen 7, and a matrix 8. A method for control and monitoring of processes in a well or reservoir using the combined liner and matrix system is also described. The combined liner/matrix system may be used in any process equipment, such as reactors, separators and storage tanks. The system may also be used in a gas/oil/water producing or injection well for well completion, control and monitoring.

  • Patent number: 6645769
    Abstract: A method for monitoring hydrocarbon and water production from different production zones/sections in a hydrocarbon reservoir and/or injection wells and detection of different phenomena such as e.g. local variations in pH, salinity, hydrocarbon composition, temperature, pressure, microorganisms, and the difference between production of formation and/or injection water from various zones/sections. The method includes dividing regions around wells in the reservoir into a number of zones/sections, and injecting or placing specific tracers with unique characteristics for each zone/section into the formation in these regions such that tracers are placed as integrated parts of the well completion or placed and immobilized in these regions through injection, squeeze or by other techniques. The tracers can also be immobilized or placed on a filter, a casing or other constructions surrounding the well in each zone/section. The tracers are specific or introduced to give specific information from each zone/section.
