    Abstract: A method and system for dehydration of a gas phase and hydrate inhibition of a liquid hydrocarbon phase in a multiphase hydrocarbon fluid stream containing water. The method may include (i) separating the hydrocarbon fluid stream into a liquid phase and a first gas phase, (ii) adding hydrate inhibitor to the first gas phase, and (iii) separating off condensed liquids and a second gas phase. The first gas phase has a water dew point that is lower than the initial multiphase hydrocarbon fluid stream and the second gas phase has a lower water dew point than the first gas phase. The hydrate inhibitor has a water content that is low enough to enable it to dry the first gas phase, the hydrate inhibitor being separated off with the condensed liquids and mixed with a part or all of the liquid phase from the separation to inhibit the liquid phase.

    Abstract: A method for operating an electrical submersible pump, ESP, lifted well, the method comprising: measuring a characteristic of the well or a characteristic of a device associated with the well; generating a first control signal for instructing a change in the operation of the ESP; generating a second control signal for instructing a change in the operation of a further device associated with the well; wherein a degree of change in each of the first and second control signals is dependent on the outcome of the measuring and on a known effect caused by sending at least one of said first control signal to the ESP or said second control signal to the further device associated with the well; and sending the first control signal to the ESP and the second control signal to the further device associated with the well.

    Abstract: A motion controller for a floating wind turbine with a plurality of rotor blades, is arranged to control a motion of the floating wind turbine in a yaw direction. The controller adjusts the blade pitch of each rotor blade so as to create a net force to control the motions. The controller includes a control action which is proportional to a yaw offset angle and/or a control action which is proportional to an integral of the yaw offset angle.

    Abstract: A modular, subsea hydrocarbon production hub 36 comprises a primary manifold 22 and a plurality of co-located extension structures 26, 30, 34. The primary manifold 22 has first connections 23 for connection a top-side facility 21, second connections 27, 35 for connection to at least one extension structure 26, 34, and third connections 25 for connection to at least one well 24. The extension structures 26, 30, 34 may comprise a secondary manifold 26, 30, having first connections 27, 31 for connection to the primary manifold 22 or another secondary manifold 26, 30, second connections 31 for connection to at least one further extension structure 26, 30, 36, and third connections 28, 31 for connection to further wells 29, 32. The extension structures 26, 30, 34 may also comprise one or more functional units, such as a pumping unit 34 or a separator unit 51.

    Abstract: A method of Enhanced Oil Recovery from oil zones in a subterranean geological formation, and from oil zones. The method including: a first injecting step of injecting a first composition including CO2 into the subterranean geological formation for a period of time; a second injecting step of injecting a second composition including CO2 and a hydrocarbon into the subterranean geological formation for a period of time, wherein the first composition and the second composition are different; and extracting oil from the subterranean geological formation.
