Abstract: A method of sealing a casing comprising the steps of deploying a thin wall tube in the region the casing is to be sealed, melting a low temperature alloy and allowing it to flow into the annulus between the thin wall tube and the casing, and allowing the low temperature alloy to solidify. The thin wall tube may include protrusions on its outer surface, of similar height so as to centralise the thin wall tube in the casing.

Abstract: A fluid injection system contains a buoy (170) for connecting with a vessel to receive fluid therefrom. At least one fluid-transporting riser (171) connects the buoy (170) with a subsea template arranged on the seabed at a wellhead for a drill hole to a subterranean void. Each riser (171) is detachably connected to a bottom surface of the buoy (170) by means of a connector arrangement (210) containing: a buoy guide member (510) configured to automatically steer a connector member (570) in a head end (300) of a riser to be connected (171) to the buoy (170), which head end (300) is moved towards the buoy guide member (510); a mating member (550) configured to attach a first sealing surface of the connector member (570) to a second sealing surface of the buoy guide member (510) when said head end (300) has been moved such that the connector member (570) contacts the buoy guide member (510), and a locking member (560) configured to lock the first and second sealing surfaces to one another when said surfaces are aligned with one another.

Abstract: Closed loop wellbore configurations with unrestricted geometry for accommodating irregular or challenging thermal gradients within a thermally productive formation are disclosed. A working fluid is utilized in the loop for extraction of thermal energy there from. The loop and the unrestricted geometry are achieved using magnetic ranging of independent drilling operations which intersect from an inlet well and outlet well to form an interconnecting segment. In conjunction with the directional drilling, conditioning operations are incorporated to condition the rock face, cool the entire system, activate the wellbore for treatment to optimize thermal transfer inter alia. The significant degree of freedom in wellbore configuration is further optimized by the absence of mechanical s. -·*> impediments such as casing or liners in the heat transfer areas.

Abstract: A subterranean radio frequency (RF) heating system includes a first tubular member having a first end, a second end, and an inner surface. A second tubular member is arranged radially inwardly of the inner surface of the first tubular member. The second tubular member includes a first end portion, a second end portion, and an outer surface portion. A first electrically insulated spacer is arranged between the inner surface of the first tubular member and the outer surface portion of the second tubular member adjacent the first end and first end portion. A second electrically insulated spacer is arranged between the inner surface of the first tubular member and the outer surface portion of the second tubular member adjacent the second end and the second end portion.

Abstract: A dewaxer flow enhancer. The dewaxer flow enhancer provides heat to the crude oil within tubing of a well bore in a drilling operation and collects the wax in a swab cup. The dewaxer flow enhancer includes a body having a head and a dewaxing barrel. The dewaxing barrel delivers heat via an induction heater and includes a tip that forms a path for the dewaxer flow enhancer as it oscillates and reciprocates within the tubing. Once sufficiently heated, wax in the crude oil has a lower viscosity and is collected via a swab cup of the head. An actuator is coupled to the dewaxer flow enhancer via a slickline or e-line and controls the position within the tubing. A controller regulates the heat and sensors detect properties of the crude oil.

Abstract: A repairable seal assembly (100) for deployment at a wellbore includes an elongate body (102), a first seal (104, 106) carried by the elongate body and configured to seal against an adjacent surface, and a transitional component (112) carried by the elongate body. The transitional component is adjustable from a first configuration in which the transitional component (112) defines a gap between the transitional component and the adjacent surface to a second configuration in which the transitional component contacts the adjacent surface to form a second seal at the adjacent surface.
