摘要： The present invention relates to a downhole stimulation system for stimulating production. The system has first and second inflatable packers (6) for isolating a production zone (10), the packers being inflated through aperture (15), a sliding sleeve valve (17) arranged between the two packers, the sleeve having an opening (19) to provide fluid communication between the inside of the well tubular and the production zone. In operation the inflatable device is set downstream of the inflation aperture of the lower packer, the well is pressurized to move the tool downstream to open the sliding sleeve valve, whereafter fracturing fluid with proppants having a size which is smaller than that of the sliding sleeve opening (19) and larger than the packer inflation aperture (15), is pumped downhole using a displacement means such as a piston element.

摘要： The present invention relates to a downhole expandable metal tubular having an axial extension, to be expanded in a well downhole to abut against an inner face of a casing or a borehole, comprising a first section having a first outer diameter, two circumferential projections having a second outer diameter which is larger than the first outer diameter, a second section arranged between the two projections, each projection having an inclined face tapering from the second outer diameter towards the second section, wherein the second section has a third outer diameter which is smaller than the first outer diameter in an unexpanded condition, and a sealing element is arranged between the projections opposite the second section, so that during expansion the second section bulges more radially outwards than the first section, forcing the sealing element radially outwards. Furthermore, the present invention relates to an annular barrier, a downhole completion and a sealing expansion method.

摘要： The present invention relates to a downhole system for unloading a liquid of a well in an annulus between an intermediate casing and a production tubular metal structure. The downhole system comprises the intermediate casing; a pump at a top of the well, configured to pressurise the annulus to displace the liquid in the annulus; the production tubular metal structure having a first inner diameter, arranged partly in the intermediate casing, thereby defining the annulus; a production packer arranged between the intermediate casing and the production tubular metal structure, and a first liquid unloading assembly and a second liquid unloading assembly, each comprising a tubular part having a wall having a second inner diameter, an outer face and an aperture, the tubular part being configured to be mounted as part of the production tubular metal structure; and a check valve connected with the outer face, the check valve having an inlet in fluid communication with the annulus and an outlet in fluid communication with the aperture. The downhole system further comprises a sliding sleeve arranged to slide along an inner face of the tubular part between an open position and closed position to open or close the aperture. Furthermore, the present invention relates to a liquid unloading method for unloading liquid of a well in an annulus between an intermediate casing and a production tubular metal structure.
