Abstract: A method of separating fluid phases in a well or riser. The method comprises: locating an inlet device of a flexible tubing at a substantially horizontal portion of the well or riser, wherein a portion of the flexible tubing extends into the well or riser and the flexible tubing terminates at the inlet device; biasing the inlet device against a wall of the well or riser; and extracting a stratified fluid phase from the well or riser through the inlet device and flexible tubing, wherein a shape of the inlet device is configured to match a shape of the wall.

Abstract: A method of sealing a well comprises creating one or more openings in a tubing installed in a wellbore, in a location for a well seal; using a wireline to locate a stinger in that location; setting the stinger in that location; and forming a seal in the well in that location, by injecting sealant through said stinger.

Abstract: A pressure joint is provided for use with a floating installation (1) that is connected to a stiff riser (3, 12). A low pressure slip joint (5) connects the installation (1) to the stiff riser (3, 12). A telescopic assembly (13, 14) fitted with a high pressure seal (15) is arranged to be fitted within the low pressure slip joint (5) when in a non-extended configuration, such that normal operation of the low pressure slip joint (5) is not impeded.

Abstract: A method for 3D imaging using phase shifted structured light, in which projection means project multiple phase shifted mask images of a transmission mask on to an object scene, the mask images being captured by a camera to form a camera image, depth information being derived from the camera image by measurement of the camera image and computation from the measurement for each of the phase shifted fringe patterns and a 3D scanner carrying out the method.

Abstract: A coupling device for connection and disconnection of bottomhole equipment includes a male part having a stinger with locking grooves and a female part includes a receptacle and a housing. The female part further includes a hold open sleeve below the receptacle, locking dogs arrange between the housing and the hold open sleeve, a locking sleeve arranged below the locking dogs, and a verifying bolt. By joining the male and female parts, the coupling device will lock automatically, as the hold open sleeve is pushed into the locking sleeve by the stinger, after which the locking dogs are pushed into the grooves of the stinger, after which the locking sleeve is pushed up over the locking dogs locking the locking dogs, after which the verifying bolt once the locking sleeve is in locking position will be pushed into an adapted opening in the locking sleeve, thereby verifying correct locking.

Abstract: Coupling device (1) for connection and disconnection of bottomhole equipment, comprising; a male part (2) having a conically shaped stinger (3) with locking grooves (4), which male part is arranged at the end of a coiled tubing; and a female part (5) comprising a receptacle (7) in an upper end (6) and a house (8) that constitutes the outer part of the female part from the receptacle to a lower end (9), which receptacle has conical shape adapted to receive the stinger of the male part, distinguished in that the female part further comprises: a hold open sleeve (10) within the house towards the upper end, adjacent and below the receptacle, which hold open sleeve is axially displaceable in the house in direction towards the lower end and has an internal diameter smaller than the receptacle; locking dogs (11) with a biasing device (12) pushing the locking dogs radially inwards, which locking dogs are arranged between the house and the hold open sleeve; a locking sleeve (13) with a biasing device (14) pushing the

Abstract: A method and a device for in situ formation of a seal (17) in a region (2) of an annulus (18) located around a pipe structure (4) in a well (18), in which the method comprises the following steps: (A) to convey a perforation device into the pipe structure (4) to a location vis-a-vis said region (2) of the annulus (16); (B) by means of the perforation device, to make at least one hole (13) through the pipe wall of the pipe structure (4) at said annulus region (2); (C) to force a liquid sealing material, which is capable of entering into solid state, through said hole (13) and further into the annulus region (2) for the filling thereof, where-upon the sealing material enters into solid state and forms said seal (17).

Abstract: A rain detection apparatus and method, comprising a camera adapted to view a surface and a processor adapted to capture at least one image from the camera, in which the processor is further adapted to generate at least one signal indicative of the presence of rain on the surface from information contained in the at least one captured image and to, optionally drive surface cleaning apparatus in response thereto, in which the apparatus is adapted to capture images focussed at a plurality of distances; in which the processor includes edge detection means adapted to detect edges visible in the at least one captured image and difference means adapted to calculate the difference between the number of edges visible between differing images; and in which the edge detection means is further adapted to disregard edges close to areas of light larger than the largest raindrop that is desired or expected to be detected.
