Abstract: A method and apparatus for sealing and filling a well which may form a part of a well abandoning operation. A tube containing well filler material is connected to a bridge plug by a connector so that the bridge plug can be positioned by moving the tube and then anchored. Once the bridge plug is anchored, the tube is disconnected and the well filler can be discharged into the well above the anchored bridge plug. In this way, the bridge plug anchoring and the filling of at least a portion of the well can be performed in a single run.

Abstract: A method and apparatus for sealing and filling at least a portion of a well is disclosed. This may form a part of a well abandoning operation. In particular, according to the present disclosure, a tube containing well filler material is connected to a bridge plug by a tube-plug connector wherein the bridge plug can be positioned by moving the tube and then anchored. Once the bridge plug is anchored, the tube is disconnected and the well filler may be discharged into the well above the anchored bridge plug. In this way, the bridge plug anchoring and the filling of at least a portion of the well can be performed in a single run.

Abstract: A device for measuring distance includes in one embodiment an electronic rotary encoder having an input shaft, a distance-measuring wheel connected to the input shaft, a base structure connected to the distance-measuring wheel, a frame structure connected to the base structure, a processor in communication with the rotary encoder, and a housing having an electronic digital display for displaying the longitudinal distance traveled by the work piece with an alpha-numeric and graphical representation of the longitudinal distance traveled by the work piece. The distance-measuring wheel reciprocates along a plane that is transverse to a longitudinal axis of the work piece. Advantageously, the display provides the longitudinal distance traveled by the work piece with an alpha-numeric and graphical representation.

Abstract: In one embodiment of the present invention, a distance measuring device for use with a power tool having an alignment area for receiving a work piece, comprises a measuring sensor proximate to said alignment area that produces a first signal corresponding to longitudinal motion of the work piece within the alignment area; a processor that receives the first signal, determines a longitudinal distance traveled by the work piece within the alignment area from the first signal, and outputs a second signal corresponding to the longitudinal distance traveled by said work piece within said alignment area; and a display receiving the second signal from the processor and providing an alpha-numeric representation of the distance traveled by the work piece within the alignment area.
