Abstract (en)
[origin: WO2016058948A1] A wellbore arrangement is provided for controlling heat transfer between a tubular member located in a wellbore and a well system. The wellbore arrangement comprises a tubular member (22) arranged to transport a produced fluid from a subterranean reservoir (20) to a surface structure, wherein the produced fluid comprises or exhibits a pressure gradient in a direction along the length of the tubular member. A lower member (28) is provided between the tubular member (22) and a wall (18) of a well system, with a space (26) being provided and extending in an uphole direction from the lower member and between the tubular member and a wall of a well system. An insulating fluid at least partially fills the space, wherein a pressure gradient of the insulating fluid in a direction along the length of the tubular member is controlled to match or track the pressure gradient of the produced fluid.
