摘要： A wellbore (1) surrounded by a formation has a horizontal section provided with a non-cemented perforated liner (3), thereby forming an annular space (4) between the liner and the formation. The annular space is divided into zones (zone 1, zone 2, zone 3) isolated from each other by means of respective external packers (6, 7, 8) arranged externally on the liner. Selective access to the zones is provided by means of an internal pipe (9) arranged inside the liner and provided with internal packers (10, 11, 12) corresponding to the respective external packers. For each of the zones, the internal pipe is provided with a valve (14, 15, 16) providing access between the inside of the internal pipe and the corresponding zone. Stimulation of the near-wellbore is performed by pumping acid or the like reactive fluid through the internal pipe into the wellbore and is performed simultaneously in adjacent zones of the annular space.

摘要： A downhole tool for investigating an outside fluid flow being adapted to operate in a well bore is presented. The downhole tool comprises a housing surrounded by an outside fluid and at least a first wave generator device. The first wave generator device preferably comprises a directional sound generator, for coupling waves into the surrounding outside fluid. The waves therein are scattered, for example, reflected, at inhomogeneities in the outside fluid, for example particles, scatterers and/or water in oil, thereby generating reflections. Said reflections are measured with a receiver device for receiving said reflections, and are evaluated using an evaluation device for determining first positions of said inhomogeneities in the outside fluid by evaluating said reflections, wherein the evaluation device is adapted to determine the outside fluid flow.

摘要： Without limitation, embodiments of the present invention relates to an offshore wellhead platform (100), the offshore wellhead platform (100) comprising a configurable support structure (200) for supporting upper parts of a plurality of conductors (210) through which one or more well processing tasks can be performed, wherein the configurable support structure (200) further provides a first position (150) and a second position (160) for the conductors (210), and the offshore wellhead platform (100) allows movement of an upper part of a conductor (210) between its first (150) and second position (160). In this way, efficiency when processing a plurality of wells is provided since repositioning of the well center is not needed or needed significantly less. Effectively, the wells are brought to the well center so-to-speak instead of the well center needing to be moved to each well.

摘要： An offshore platform for use in combination with an offshore rig comprises an upper deck defining an upper deck aperture which is alignable with a rig aperture of the offshore rig, when said offshore rig extends over the upper deck, to permit objects to extend between the offshore rig and through the upper deck. The offshore platform further includes a sheath arrangement aligned with the upper deck aperture and extending upwardly relative to the upper deck to be alignable with the rig aperture, wherein the sheath arrangement defines a confinement zone for confining objects which pass downwardly from the offshore rig through the rig aperture.

摘要： Use fresh water or water with sufficiently reduced salinity to trigger burst of bacterial cell wall due to osmotic pressure gradient. Combine the freshwater with conventional biocide treatment and pigging to increase the likelihood of killing the bacteria responsible for reservoir souring.
