The tube extends beyond the peripheral opening(s) so as to deliver gas to a region of the element wall which is remote from the end cap.

Abstract: 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.

Abstract: An underwater system (1) has a hydrocylone (5) for separating sand from seawater, and a pump (8) downstream from the hydrocylone (5) for drawing seawater upstream of the hydrocylone into the hydrocylone. The sand separated from the seawater is collected in a sand storage device (6) below the hydrocyclone. The pump (8) pumps the seawater from which the sand has been removed into a water injection well (16) and a portion of the seawater is diverted into a sand extraction device (7) beneath the sand storage device (6) to flush away the sand collected therein.

Abstract: A system (1) for combating the formation of emulsions in production fluid has a control system which compares the volumetric flow rates of oil and water separated from production fluid in a separator vessel (16). When the ratio of the separated oil approaches that where emulsions are expected to form, a portion of the separated water is diverted into a fluid mixing device (10) and commingled with the production fluid being conveyed to the separator vessel (16) so that the commingled fluid has an oil to water ratio outside the range of oil to water ratios at which emulsions are likely to form. Alternatively, instead of comparing the volumetric flow rates of separated oil and water, the system can detect the presence of emulsions in the fluid in the separator vessel (16) by having a nucleonic level sensor in the vessel, the sensor being linked to the control system.
