Abstract: A force transferring connector (400) having a box part (401). A pin section (408) enters the box part with a lug (411). The box part has a locking shoulder (415). When the pin section (408) is inside the cavity, the lug (411) rotates between a non-engaged and an engaged state. The connector (400) has an electric connection arrangement (470) guiding electric power and/or electric signals. The electric connection arrangement (470) is in a connected state when the pin section (408) is inserted into the receiving cavity (405) and in a non-connected state when the pin section (408) is not inserted into the receiving cavity (405).

Abstract: A hockey puck (1) comprising an accelerometer (101) arranged in a recess (5) of a puck body (3). The accelerometer (101) is configured to measure the acceleration of the hockey puck (1) in at least one direction in x-y-z coordinates. The hockey puck further comprises a power supply (25) and a control unit (109) configured to read sensor input from the accelerometer (101) and to provide a control unit output based on said sensor input.

Abstract: A fishing tool (1) configured to retrieve a fish (100) from a wellbore, having a fish engagement arrangement (3) with fish engagement means (5) configured to lock the fishing tool to the fish inside a well. The fishing tool (1) has an electrically actuated fish disengagement arrangement (4), which is configured to unlock the fishing tool from the fish, wherein the fish disengagement arrangement (4) comprises an electric actuator (13). The fish disengagement arrangement (4) comprises a direct mechanical force link (6) between the electric actuator (13) and the fish engagement means (5), wherein the direct mechanical force link is configured to connect a mechanical force from the electric actuator (13) to the fish engagement means (5).

Abstract: An installation apparatus for installing a liner in a subterranean formation includes a housing having an internally arranged flexible member operatively connected to a bore-forming device at one end and to a control module at another end. An opening is arranged in a housing wall through which the flexible member and device may be passed. A liner is arranged around at least a portion of the flexible member between the opening and a first support member. The first support member is arranged to move inside the housing in a direction towards the opening, and a second support member is configured to movably support at least a portion of the flexible member in the region between the control module and the first support member. A method of installing a liner in an inverted drainhole is disclosed.
