Abstract: A tool assembly for performing a wellbore operation including an actuatable tool, a location device, and on-board controller are together dimensioned and arranged to be deployed in the wellbore as an autonomous unit. The actuatable tool, such as a perforating gun having associated charges, perforates a wellbore along a selected zone of interest. The location device, such as casing collar locator, senses the location of the actuatable tool based on a physical signature provided along the wellbore. The on-board controller or micro-processor is configured to send an activation signal to the actuatable tool when the location device has recognized a selected location of the tool based on the physical signature. The tool assembly further includes a multi-gate safety system. The safety system prevents premature activation of the actuatable tool.

Abstract: A method and apparatus for forming a plug in a passageway. The apparatus comprises a carrier which in use is lowered into the passageway, the carrier comprising an elongate body (3) of a material resistant to creep which supports at least two spaced apart portions (5) that are a sliding fit in the well (1) such that a gap is formed between each of the potions and the passageway. A body of material (15, 16, 17) the :melting point of which is higher than the temperature within the passageway and which expands as it solidifies is supported on the carrier. A heating device is provided for melting the body of material such that the melted material fills a space defined between the first and second portions. The carrier is cooled preferentially to ensure that the molten material solidifies rapidly adjacent the two spaced apart portions, thereby resisting flow of the material as it solidifies past the spaced apart portions. Means (21) are provided to obstruct the gaps formed between the portions arid the passageway; the obstructing means being displaced into the gaps as a result of melting of the body of material or as a result of any creep of material after it has been melted and solidified.

Abstract: A bridge plug (305) includes a cylindrical body (300) having a longitudinal bore (308). First and second lock ring assemblies (340, 360) are installed on the outer surface of the body and are designed to move in a single direction. A bi-directional slip member (310) to provide axial resistance in two directions and a sealing member (330) are located on the exterior of the body. The sealing member (330) is disposed between the lock ring assemblies (340, 360) and actuated by movement of the ring towards each other. The slip (310) is a circular with teeth on the outer surface arranged to break into segments with radial pressure. The slip is actuated by force from a sloped shoulder on a first end of the body and a sloped surface on the second lock ring assembly. Both lock ring assemblies move toward the shoulder, thereby setting the sealing member therebetween and setting the slip between the second lock ring assembly and the shoulder.
