Abstract: There is described thermal hydrocarbon recovery apparatus for thermal recovery of hydrocarbons from a geological formation and an associated method. In an embodiment, the apparatus may be provided with inflow control devices for autonomously adjusting a flow of fluid through the flow control device. The flow control devices are provided to tubing, which is located in a wellbore in use and provides fluid connection between the geological formation and an inside of the tubing. The tubing is arranged to perform at least one of: injecting steam into the geological formation for heating hydrocarbons; and moving steam heated hydrocarbons from the geological formation to the surface.

Abstract: A method of treating an oil well to inhibit scale formation. An oil soluble scale inhibitor is injected into the well during the completion phase. The inhibitor hydrolyses on contact with connate water in the well and the active part enters the water phase. It remains in the water phase while oil is extracted and until the water breaks through. At that stage, the inhibitor becomes active in inhibiting scale formation.
