Abstract: The invention relates to a connecting assembly to be plugged into a mating receptacle in a wellbore, comprising a first sleeve including a second sleeve and having a top connecting end and a bottom connecting end, characterized in that: —the first sleeve comprises the bottom end and has a top end opposite to said bottom connecting end, said bottom connecting end being provided with an end cap for preventing entrance of materials and capable of being opened; —said second sleeve comprises said top connecting end located outside of the first sleeve and has a bottom end opposed to said top connecting end; —said connecting assembly comprises a locking mechanism adapted to lock said second sleeve in a position relative to said first sleeve such that the bottom end of the second sleeve is inside said first sleeve, and —the dimensions of the first sleeve and second sleeve are adapted such that when said locking mechanism is unlocked, said second sleeve is allowed to move relative to said first sleeve to impinge and o

Abstract: Stop collars may be fixedly mounted on a liner or other tubular member. The stop collar comprises a first sleeve and a second sleeve. The sleeves are adapted to extend around the outer circumference of the tubular member and are engaged by threaded connections. The sleeves provide opposing inner thrust surfaces. The collar further comprises a radially expandable gripping member disposed between the opposing thrust surfaces. The sleeves may be drawn together by rotation about the threaded connection to cause the thrust surfaces to bear on the gripping member and expand the gripping member radially inward into frictional engagement with the tubular member.

Abstract: The support 10 of the present invention resembles a conventional Acrow prop which may be used for temporarily supporting a load. In particular, the present invention is arranged to support a surface at a static position. For example, the surface may comprise a ceiling/beam/lintel within a structure wherein the usual permanent supports for the ceiling/beam/lintel are being replaced or deemed temporarily insufficient. However, the present invention can be used in numerous situations where a support 10 is required and for which the support 10 can be quickly and easily installed. The present invention provides (hydraulic) movement means to move the upper end relative to the lower end. In addition, the present invention provides retraction prevention means to prevent the upper end moving towards the lower end while supporting the load and prevents the inner core member 14 being forcibly retracted back into the outer sleeve member 12 due to the compressive force of the load.

Abstract: The invention relates to a swivel sub for a string to be lowered into a wellbore and a method of operation in a wellbore, wherein such swivel sub is used and comprises: —a first end provided with connection means for connecting a bottom section of a string; —a second end provided with connection means for connecting an upper section of the string; —a first member, including the first end and a sleeve portion opposed to the first end; —a second member including the second end and comprising a section opposed to the second end and partially located within the sleeve portion; the first member and the second member being arranged to rotate relative to each other.
