摘要： Gas is supplied from a host facility (2) to an underwater gas compressor (10) via a connecting pipeline (6) and the gas compressor is connected to a plurality of gas injection wells (7) for a hydrocarbon reservoir via well supply flowlines (8). The gas compressor (10) compresses the supplied gas to a higher pressure, and drives the gas into the reservoir via the flowlines (8) and gas injection wells (7) at a pressure at least as high as the pressure of the production fluid in the reservoir. This raises the overall pressure in the reservoir to drive production fluid there to the host facility (2). The compressed gas may alternatively be injected into production fluid in a production well to provide a gas lift effect.

摘要： A pressure protection system (32) has a docking manifold (44) to which an upstream portion (36) and a downstream portion (38) of a pipeline (34) are connected. Also connected to the docking manifold (44) is a retrievable module (64) which has a conduit circuit (66) that connects the upstream and downstream portions of the pipeline (34) enabling fluid to flow between the two portions (36, 38). The conduit circuit contains two fail-safe valves (72) which are controlled by a control module (80) within the retrievable module, and two pressure transmitters (76) co-operable with the control module (80). When wither pressure transmitter (76) senses fluid pressure in the conduit circuit (66) to be above a threshold value then it causes the control module (80) to effect closure of the valves (72) preventing the pressure rise from reaching the downstream portion (38) of the pipeline (34).

摘要： A mixture of fluids is conveyed from a hydrocarbon reservoir and comprises gas and slugs of liquid. The mixture is passed through a slug catcher vessel (12) which temporarily retains the slugs of liquid. The gas is passed through a gas compressor (18) and the resulting pressurised gas is then conveyed to a remote location. When a liquid slug is detected in the slug catcher vessel (12), liquid is drawn from the vessel by an injector device (24) and entrained into the flow of gas downstream of the gas compressor (18) until the level of the interface between the gas and liquid in the vessel reaches a sufficiently low level. The system may alternatively be configured to accommodate a flow of liquid containing slugs of gas.

摘要： Method and apparatus for assisting the flow of production fluid from a hydrocarbon wellbore (4) to a remote host facility (16) including a separation facility (6) situated close to the wellbore (4). Jetting fluid is supplied initially from the host facility (16) to a downhole jet pump (14) via the separation facility (6) for assisting the flow of production fluid from the wellbore (4) to the separation facility (6) where the resulting mixture enters one of two parallel gravity separation chambers (32). Separated jetting fluid (60) is recirculated to the jet pump (14) via a pump (38) and production fluid is routed to the host facility via a production pipeline (18). A jetting fluid supply pipe (20) can be of relatively small diameter and the production pipeline (18) does not have to be enlarged to accommodate jetting fluid returned to the host facility (16).

摘要： A system (1) for extracting subsea hydrocarbon fluid has five discrete subsea developments (10, 12, 14, 16, 18) for hydrocarbon extraction linked to four hydrocarbon receiving facilities (2, 4, 6, 8) by a pipeline network (94). Each subsea development (10, 12, 14, 16, 18) has a manifold to which pipelines of the network (94) are connected, and a pair of retrievable modules (22) docked on the manifold. Each module has a control pod which is able to control flows of fluids between the subsea developments and between the subsea developments and the receiving facilities, and each control pod is connected to monitoring devices for monitoring parameters pertaining to the subsea developments. Parameters are monitored at a first one of the subsea developments and a requirement for a first fluid type is identified and parameters at another second one of the subsea developments are monitored and a surplus of the first fluid type is identified. The relevant control pods are then operated to enable a quantity of the first fluid to be conveyed from the second to the first subsea development via the pipeline network (94).

摘要： A system for controlling the operation of devices (61, 62, 63) of a hydrocarbon production system has two reprogrammable central controllers (100) contained in a retrievable module (49a) of a seabed facility (20') associated with a hydrocarbon field (170). Local controllers are configured to control the operation of specific devices, such as actuators (61), sensors (62) and valves (63) within the module (49a) and within tree wellheads (30') of the field (170) and are locally connected to these devices (61, 62, 63). A single common data bus (130) links the central controllers (100) and the local controllers and enables data to be transmitted between the central controllers (100) and the local controllers in response to the central controllers (100) receiving signals. Each local controller has a microprocessor for processing the data transmitted to it, and the processed data is transmitted between the local controller and its associated devices (61, 62, 63) in accordance with the processed data so as to locally control the operation of those devices.

摘要： A system for separating fluids from a hydrocarbon well production fluid mixture at a subsea location has a centrifugal separator (16) for separating the mixture into gas and liquid. A hydrocyclone separator (32) then separates the liquid into oil and water and an oil-in-water sensor (38) detects the amount of oil in water leaving the separator. If the sensor (38) detects that the water contains more than the prescribed amount of oil, the water is recirculated through the hydrocarbon separator (32) for removal of further oil form water. The hydrocyclone separator (32) has a level interface sensor (66) and if this sensor detects that the oil/water interface is not within prescribed limits for optimum separation of the oil and water, the amount of oil removed from the separator is adjusted until the oil/water interface is within the prescribed limits. The sensors (38, 66) are connected to a control means (68) which controls electrically actuable control valves (42, 58) to cause the water to be recirculated to adjust the amount of oil removed from the hydrocarbon separator. The system also includes a gas slug detection device (14) upstream of the centrifugal separator (16) for sensing the presence of a gas slug in the production fluid. A liquid flow control valve (21) is adjusted by the control means (68) to ensure that the level of liquid in the centrifugal separator (16) does not fall below prescribed limits.

摘要： Production fluid mixture is directed through a sand removal unit (12) in a retrievable module (1) installed in a modular seabed processing system, and the unit (12) collects sand from the mixture. The production fluid mixture then enters a fluid separation chamber (17) in the module (1) where it is separated into a gas and a mixture of oil and water. Seawater is drawn in from outside the module and is pumped into the sand removal unit (12) to flush the collected sand. The mixed flushed sand and seawater is commingled with the mixture of oil and water downstream of the fluid separation chamber (17) and the commingled mixture is conveyed to a host facility. There, the sand is separated from the commingled mixture and is disposed of.
