Abstract: Methods of monitoring for influx and/or loss events in a wellbore are disclosed. One method comprises: receiving a measurement relating to fluid entering or leaving the wellbore, wherein the measurement is selected from flow out rate and active volume; and comparing the measurement with an expected value for the measurement to provide a deviated measurement value. The method further comprises receiving a pump pressure value of a pump associated with the wellbore; and comparing the pump pressure value with an expected pump pressure value to provide a deviated pump pressure value. It is then established whether an influx event and/or it is established whether a loss event may have occurred based on at least the deviated measurement value and deviated pump pressure value. Systems configured to monitor for influx and/or loss events in a wellbore are also disclosed.

Abstract: An active rotating separator is disclosed, comprising a separator drum arranged to receive multiphase fluid via an upstream end and to deliver separated fluid phases from a downstream end of the drum. An electric motor is installed in the flow through the drum, the motor operable to generate rotation in the fluid flow that passes through the drum, the motor comprising an open rotor permitting through-flow of fluid through the motor.

Abstract: A subsea heat exchanger comprising a bundle of tubes comprising at least one tube winding arranged to operate submerged in water and effective for guiding a fluid to be cooled by surrounding water in contact with the tube, the bundle of tubes defining a longitudinal extension and a perimeter. A plurality of nozzles are distributed in spatial relation to said perimeter, wherein the nozzles are effective for discharging jets of water impinging on the tubes, the nozzles oriented to induce, in the ambient water volume, a displacement that passes the perimeter at a plurality of locations and directions.

Abstract: A device for removing solids from a fluid containment space. A hood is arranged or intended to be arranged at a bottom surface of the fluid containment space. At least one inlet opening and at least one outlet opening are provided on a first side of the hood. The hood is provided with one or more elements for directing fluids through the respective outlet opening on the first side of the hood from the inner space of the hood to the fluid containment space exterior of the hood in an essentially horizontal direction or in a direction towards the bottom surface of the fluid containment space. Also provided are a separator including such a device and a method for removing solids from a fluid containment space.

Abstract: A method and a system for separating the phases of a multiphase fluid from one or more wells. The system includes at least one first gravity separator and at least one second gravity separator, and elements for conducting the fluid from the well or wells to the first and second gravity separator(s). The system includes elements for selectively conducting the fluid to the first and second gravity separators either in parallel or in subsequent steps depending on the properties of the well fluid and process conditions.

Abstract: A method and device for detecting an accumulation of a solid material in a vessel that contains at least one fluid phase. The device includes an electric conductor element that is positioned in a region inside the vessel where the accumulation is likely to occur, the electric resistance of the conductor element being a function of the temperature thereof, elements for providing electrical power to the conductor element and elements for repeatedly measuring the electrical resistance of the conductor element.
