Abstract: A method for joining fiber optic cables includes sliding a sleeve over a first fiber optic cable, joining a first set of optical fibers of the first fiber optic cable to a second set of optical fibers of a second fiber optic cable, sliding the sleeve over the first and second fiber optic cables, and joining the sleeve to a first exterior casing of the first fiber optic cable and to a second exterior casing of the second fiber optic cable.

Abstract: A technique facilitates forming cavities, e.g. perforations, into a geological formation. A jetting tool is moved downhole into a borehole, and an abrasive fluid is pumped down through the jetting tool. The abrasive fluid is discharged under pressure through a plurality of jetting nozzles to form jets of the abrasive fluid which act against a surrounding wall, e.g. a casing or other borehole wall. The jetting nozzles, and thus the jets, are oriented such that a rebound effect of the jets does not detrimentally impact the jetting tool. Consequently, the jets can be used to cut perforations through the surrounding wall and into the formation without eroding or otherwise detrimentally affecting components of the jetting tool.

Abstract: The present invention relates to a packer cup 5 having a deformable leading edge 20 which moves away from well bore or casing obstructions as the packer cup 5 is moved into a well bore. The anaxisymmetric deformable leading edge 20 can be formed by an angled leading edge 19 which presents only a portion of the leading edge 18 to a well bore obstruction and allows the edge 19 to move past the obstruction with little or no longitudinal force. Another embodiment provides an anaxisymmetric deformable leading interior edge 72 which is unduloid providing alternatively stiff and deformable sections 74, 76 of the edge 72 to move past the obstructions.
