    摘要: A method of creating a zonal isolation above a target zone in an underground wellbore comprises: inserting a slurry injection tubing into the wellbore; arranging within an annular space surrounding said tubing an particle accumulation means, such as an expandable screen or an area where the slurry velocity is reduced; and pumping a slurry comprising a carrier fluid and granular material down via the slurry injection tubing and the target zone and then up into the annular space, such that at least some granular material accumulates and forms an elongate zonal isolation in the annular space between the target zone and the particle accumulation means, which zonal isolation is removable and exerts a limited radial force to the surrounding formation, thereby reducing the risk of formation damage.

    摘要: An automated method for forge welding tubulars including heating the tubular ends to be joined in a welding chamber while the heated tubular ends are maintained aligned and parallel relative to each other and at a small spacing, whereupon the heated tubular ends are pressed together while a reducing shield gas is injected into the chamber. The positions of the tubular ends are monitored by cameras which are coupled to a pyrometric and position monitoring system which automatically adjusts the position of the tubular ends relative to each other and the heat supplied to the tubular ends during the heating step until the tubular ends have reached a predetermined temperature, whereupon the tubular ends are moved towards each other along a distance which exceeds the spacing monitored between the tubular ends during the heating step with a selected extra distance, such that the tubular ends are firmly pressed against each other and the amount of external and/or internal upset of the tubular ends in the welding zone is limited to an acceptable level.

    摘要: A method of installing a sensor in a borehole drilled through underground formations, wherein the borehole is drilled with a hollow drill string formed from a series of pipe sections connected end-to-end, a drill bit being positioned at one end of the drill string and having an closure that is operable to provide an opening between the borehole and the inside of the drill string, the method comprising: drilling the borehole to a predetermined depth using the drill string and bit; partially withdrawing the drill string from the borehole so that the drill bit is positioned above the predetermined depth; lowering a sensor inside the drill string by means of a cable; operating the closure so that the sensor can pass out of the drill string into the borehole; and progressively withdrawing the drill string and drill bit from the borehole over the cable so as to leave the sensor in the borehole.
