A flow control tool for controlling the flow of fluid in a wellbore, the tool comprising: a hollow body defining a through-bore, and at least one flow port extending through a wall of the body for selective communication with the through-bore; and a valve element mounted within the through-bore of the body, the valve element being movable within the through-bore under applied fluid pressure between: a circulation flow position in which the valve element closes the through-bore of the body and allows fluid communication with the at least one flow port, so that fluid flow along the through-bore and out of the body is prevented and fluid flowing into the body is directed through the at least one flow port; and a through-bore flow position in which the valve element closes the at least one flow port and allows fluid flow along the through-bore of the body, so that fluid flow along the at least one flow port is prevented and fluid flowing into the body is directed along the through-bore and out of the body; in which the valve element is locatable in: a first intermediate position; and a second intermediate position; characterised in that: in the first intermediate position, the at least one flow port is closed and fluid flowing into the body is directed along the through-bore and out of the body along a first intermediate flow path defining a first intermediate flow area, thereby providing a first intermediate pressure indication; and in the second intermediate position, the at least one flow port is closed and fluid flowing into the body is directed along the through-bore and out of the body along a second intermediate flow path defining a second intermediate flow area which is different to the first intermediate flow area, thereby providing a second intermediate pressure indication which is different to the first intermediate pressure indication. a hollow body defining a through-bore, and at least one flow port extending through a wall of the body for selective communication with the through-bore; and a valve element mounted within the through-bore of the body, the valve element being movable within the through-bore under applied fluid pressure between: a circulation flow position in which the valve element closes the through-bore of the body and allows fluid communication with the at least one flow port, so that fluid flow along the through-bore and out of the body is prevented and fluid flowing into the body is directed through the at least one flow port; and a through-bore flow position in which the valve element closes the at least one flow port and allows fluid flow along the through-bore of the body, so that fluid flow along the at least one flow port is prevented and fluid flowing into the body is directed along the through-bore and out of the body; a circulation flow position in which the valve element closes the through-bore of the body and allows fluid communication with the at least one flow port, so that fluid flow along the through-bore and out of the body is prevented and fluid flowing into the body is directed through the at least one flow port; and a through-bore flow position in which the valve element closes the at least one flow port and allows fluid flow along the through-bore of the body, so that fluid flow along the at least one flow port is prevented and fluid flowing into the body is directed along the through-bore and out of the body; in which the valve element is locatable in: a first intermediate position; and a second intermediate position; characterised in that: in the first intermediate position, the at least one flow port is closed and fluid flowing into the body is directed along the through-bore and out of the body along a first intermediate flow path defining a first intermediate flow area, thereby providing a first intermediate pressure indication; and in the second intermediate position, the at least one flow port is closed and fluid flowing into the body is directed along the through-bore and out of the body along a second intermediate flow path defining a second intermediate flow area which is different to the first intermediate flow area, thereby providing a second intermediate pressure indication which is different to the first intermediate pressure indication. in the first intermediate position, the at least one flow port is closed and fluid flowing into the body is directed along the through-bore and out of the body along a first intermediate flow path defining a first intermediate flow area, thereby providing a first intermediate pressure indication; and in the second intermediate position, the at least one flow port is closed and fluid flowing into the body is directed along the through-bore and out of the body along a second intermediate flow path defining a second intermediate flow area which is different to the first intermediate flow area, thereby providing a second intermediate pressure indication which is different to the first intermediate pressure indication.
