There are described a method and a device for recovering drilling fluid which is used in connection with the provision of a subsea well (10), in which the drilling fluid is circurlated from a vessel (20) on a sea surface (21) via a drill string (12) and out through a drill bit (12') into an annulus (13) which is defined by a borehole and the drill string (12), the device including: a filtering device (1) which is connected, in respect of fluid, to said annulus (13) and which is arranged to contain drill cuttings (4) and drilling fluid; and a fluid line (7) which extends from a portion of the filtering device (1) to the vessel (20), the fluid line (7) being arranged to carry drilling fluid which has been separated from the drill cuttings (4) back to the vessel (20). |
