Abstract: A rotary table device is provided with means arranged for suspension of a pipe string. The rotary table comprises a rotary ring arranged rotatably about the central axis of the rotary table. The rotary ring is formed by two or more ring sections, each connected to a system comprising a bearing housing section rotatable relative to a base section, a bearing housing groove being formed in a base contact surface on the bearing housing section and a corresponding base groove being formed in an opposing bearing housing surface in the base section. The grooves form a curve-shaped track for a roller body and the groove has a curvature center coinciding with the central axis of the rotary table. The rolling diameter of the roller body exceeds the collective depth of said grooves, and a channel connecting the end portions of the bearing housing groove is formed in the bearing housing section.

Abstract: A method for controlling a drilling operation, in particular in production or exploration drilling for hydrocarbons, in which a drill bit is arranged on an end of a drill string and, by rotation and pressure against an underground formation, is arranged to form a borehole, and in which a drilling fluid is circulated through a pipe bore into the borehole at the drill bit to convey cuttings out of the borehole. The method comprises the steps of: providing data on the particle size distribution of the cuttings; comparing the provided particle size distribution with data for the desired particle size distribution when drilling in the underground formation of interest; and adjusting the critical control parameters of the drilling operation with the aim of achieving a cuttings particle size distribution which corresponds, to the greatest extent possible, to the desired particle size distribution.

Abstract: The invention comprises a sealing body (15) separating device) which can be used to separate fluids in risers used in offshore oil production from drilling vessels at the sea surface. The invention is characterized in that the sealing body (15) can be placed in position above the wellhead (13) using several appropriate methods and, in an especially preferred application, by utilizing an installation tool (27) which is not sealing against the inner wall of the riser and which contains a suitable positioning means (28), and that the body (15) which forms a seal against the inner wall of the riser separates fluids during the replacement of drilling fluid with water and of water with drilling fluid. The body (15) can be displaced using hydraulic force upwards in the longitudinal direction of the riser in that fluid is pumped at a relatively high pressure down the externally located smaller pipes (9, 10, 11) of the riser. The body can be used while the drilling vessel (1) heaves relative to the seabed (3), and it is independent of the drilling vessel's drawers for the drill string (21) while the fluid is being replaced.
