A fitting arrangement and method of securing a fitting arrangement to a surface is provided. A plurality of adjacent fittings is coupled to and extends from a mounting surface of a structure in a well bore. Each fitting has an engagement surface that is configured to engage with an installation tool for coupling the fitting to the structure. The engagement surfaces of the adjacent fittings in the plurality are offset from each other to thereby define a clearance for the installation tool.

The invention is a system and method a system used to control multiple downhole tools with one control line. The downhole tools may comprise any hydraulically actuated tools, such as valves, packers, or perforating guns. Each tool is associated with an indexer, in one embodiment, so that the tools can be operated in concert and as a system.

A method and system is provided for perforating a casing in a hydrocarbon well so as to avoid perforating in a direction where a cable resides. A mass of metallic material is clamped to the casing at a predetermined offset angle with respect to the cable. The angular position of the metallic mass is detected using a detector placed inside the casing. Then, a perforating gun is oriented based on the detected angular position of the metallic mass and the predetermined offset angle. Finally, the casing is perforated so as to avoid damage to the cable. The cable comprises a number of electrical conductors and is used to communicate with permanent sensors located on the cable in the vicinity of the casing to be perforated.
