| 41 | COMPACT JAR FOR DISLODGING TOOLS IN AN OIL OR GAS WELL | EP10822730.7 | 2010-10-08 | EP2486225A2 | 2012-08-15 | EVANS, Robert, W. |
| This invention relates to a jar used to dislodge tools stuck in a well. The jar includes two housing portions movable with respect to each other. A release collet forms a portion of one of the housings. A release sleeve is carried by a mandrel and is located within the release collet. After a given amount of movement of the housing with respect to the mandrel, the release mechanism is activated and the two housing sections rapidly move with respect to each other. A hammer portion of the mandrel then strikes an anvil in the anvil housing, thus applying an upward force to the tool lodged in the well. | ||||||

The impactee includes a second down-hole tool connector distal from the first down-hole tool connector and a plurality of flexible coupling fingers. The biasable member is detachably engaged by the plurality of flexible coupling fingers in a pre-impact position and is configured to disengage the plurality of flexible coupling fingers in response to a tensile force applied across the first and second down-hole tool connectors reaching a predetermined quantity. The impactor and the impactee are configured to impact in response to the disengagement of the biasable member and the plurality of flexible coupling fingers. In one embodiment, the impact jar may be employed in either of e-line and slickline applications. | ||||||

| 47 | REVERSE PERCUSSION DEVICE | EP95920605 | 1995-05-15 | EP0759116A4 | 1999-08-11 | CAMPBELL PAUL |
| A reverse percussion device (30) for use with hydraulic percussive drills is provided. The reverse percussion device (30) includes a cycling piston (34), valve (36) and anvil (38). The piston (34) and valve (36) move in opposing directions between low and high pressure passages automatically until a lodged drill bit (18) is freed, thereby facilitating removal of the drill bit (18) from the drilled hole and eliminating alternate loosening and tightening of drill string threads (14). The reverse percussion device (30) preferably includes an automatic disabling feature which causes the reverse percussion operation to cease when the bit is free to retract normally. | ||||||
