| Sealing elements have lubricating seal profiles for communicating fluid between the sealing elements and the sealed drill string tubular or other oilfield component while the sealed drill string tubular or other oilfield component rotates or moves vertically relative to the seal elements. The same fluid used for drilling may also be used for seal lubrication, such as water, drilling fluid or mud, well bore fluid or other liquid or gas. The sealing elements may be disposed with a seal housing, which may be positioned with a marine riser, or subsea without a marine riser. The seal housing may prevent rotation of the seal elements with the sealed drill string tubular or other oilfield component. Alternatively, the seal housing may be an RCD that allows the sealing elements to rotate. The lubricating seal profiles include a wave pattern, a saw-tooth high film pattern, a downwardly inclined passageway pattern, an upwardly inclined passageway pattern, and a combined upwardly and downwardly inclined passageway pattern. In one embodiment, a stripper rubber seal element may have a lubricating seal profile on the inwardly facing bore surfaces of both its nose and throat sections for sealing with drill string tubulars and other oilfield components having different diameters. Dual seals with two annular spaced apart sealing surfaces, with or without lubricating seal profiles, may seal with a drill string tubular or other oilfield component. In another embodiment, differential pressures across two seal elements may be managed by filling the cavity between the two sealing elements with cuttings-free drilling fluid, mud, water, coolant, lubricant or inert gas at desired amounts of pressure. | ||||||
| 45 | Gas-blanketed piping connections | EP11151647.2 | 2011-01-21 | EP2354439A2 | 2011-08-10 | Wilde, Glenn |
Migration of air through a flanged connection into piping containing a gas under negative pressure is prevented by disposing concentric inner (132) and outer (131) gaskets between the flange faces (112A,122A), so as to form an annular chamber (140) into which a blanketing gas is introduced at a pressure higher than atmospheric. Air tending to migrate through the outer gasket (131) is blocked by the higher-pressure blanketing gas in the annular chamber (140). The blanketing gas pressure is maintained at a level higher than atmospheric notwithstanding any fugitive emissions through the outer gasket (131). The annular chambers of multiple flanged connections may be interconnected to blanket multiple flanged connections (160-1,160-2) using a single source of blanketing gas. The blanketing gas may be the same type as the gas under negative pressure. In sour service applications, an inert blanketing gas may be used to prevent leakage of sour gas to atmosphere through flanged connections. In alternative embodiments, the principles of the invention may be adapted for use with other types of connections including threaded piping connections, and for use with piping carrying liquids.

| 46 | Method and plugging material for reducing formation fluid migration in wells | EP10183631.0 | 2000-09-22 | EP2290191A3 | 2011-03-30 | Svindland, Alf |
The invention relates to a method to hinder/reduce the migration of formation fluids in wells, primarily in connection with plugging of oil wells. A mass of particulate matter consisting of naturally occurring and/or synthetically produced granular material, which may be suspended in a suitable liquid, is placed in or around the well casings (10, 12, 14 and 16) and production tubing (28) to form a plug. The particulate material mentioned can replace conventional mechanical plugs (40, 44, 48) and cement plugs (42, 46, 50). The particulate material plug (52) must have a sufficient length in the well, the particulate material must be suitably sorted and packed and have suitable chemical/physical properties, such that the permeability of the plug (52) becomes sufficiently small that the well is effectively plugged since the time required for formation fluids, e.g. oil, to migrate through the plug may be several thousand years. The plug of particulate matter (52) can also change in shape and adapt to possible geometry changes in the well, for example as a consequence of displacements in the Earth's crust or corrosion of metals in the well, and thereby hinder/minimise possible leaks.

| An offshore universal riser system. A riser system includes a valve module which selectively permits and prevents fluid flow through a flow passage extending longitudinally through a riser string. An anchoring device releasably secures the valve module in the flow passage. A method of constructing a riser system includes the steps of installing the valve module in the flow passage, and installing at least one annular seal module in the flow passage. The annular seal module is operative to prevent fluid flow through an annular space between the riser string and a tubular string positioned in the flow passage. Drilling methods include injecting relatively low density fluid compositions into the annular space, and selectively varying a restriction to flow through a subsea choke in a drilling fluid return line. The riser string, including housings for the various modules and external control systems, is dimensioned for installation through a rotary table. | ||||||

| The invention concerns a suction substructure (2) for the setting of one or more conductor casing strings (14) in connection with drilling of at least one underwater well, preferably a petroleum well, and where the use of a suction substructre (2) renders possible the installation of conductor casing by means of known piling technique and by means of a suitable surface vessel, e.g. a suitable boat. The suction substructure (2) consists of a substructure body, which is joined in a pressure sealing manner, and which is shaped with a downwards open end part (8), which is set some way down in the seabed sediments (22). Thereupon water is pumped out of the suction substructure (2), which causes a negative pressure in the suction substructure (2), and where the suction substructure (2) thereby is pressed further down into the seabed sediments (22). The suction substructure (2) is in addition in its upper end fitted with at least one guide opening (10) and possibly an appurtenant guide funnel (12), and an appurtenant releasable and pressure sealing lid (32), and where the guide funnel (12) will be able to guide and give lateral support to a conductor casing string (14) during its subsequent installation. | ||||||

A subterranean well fluid conduit transmission welding habitat has an outer air supportable arcuate dome (101) which is mounted over the well entry point (P) to entrap welding slag and sparks. A fire-resistant shield (102) is disposed around the interior of the dome. Air is supplied to the dome through an inlet (103) for selectively suspending the habitat. A conduit (105), e.g. a filter, is provided through the top of the dome to permit discharge of smoke including particulate matter resulting from the welding procedure. The air supply may be opposite to with the smoke discharge whereby the supply of air forms a carrier fluid for transmitting the smoke and particulate matter out of the dome. |

| The present invention relates to a closed type container for protecting a groundwater tube well and, more particularly, to a closed type container for protecting a groundwater tube well, which has a tube well and a tube well protection unit attached to each other by banding in order to prevent foreign matters from entering the container, and which can be easily installed and maintained by having light weight as being made of synthetic resins. The closed type container according to the present invention comprises an intake tube, an underwater motor pump, a casing, the tube well, an intake cover plate, a flow meter, a discharging tube, a water outlet device, a protection container, and a protection container lid. In the lower part of one side of the protection container, a penetrating hole is formed so that the tube well can be inserted. Along the penetrating hole, the tube well protection unit, which has an open upper part covering the outer wall of the tube well inserted toward the inside, is formed as a hollow cylinder. Also, a banding unit is formed so that foreign matters cannot flow into the gap between the tube well and the tube well protection unit. | ||||||
