  • Patent number: 6942033
    Abstract: A technique that is usable with a subterranean well includes orienting shaped charges of a perforating gun to extend partially around a longitudinal axis of the gun. The perforating gun is oriented in the well to direct the shaped charges away from a water boundary. In response to this orientation of the perforating gun, the shaped charges are fired. The perforating gun and shaped charges may also be oriented in a deviated well to compensate for the anisotropic permeability of a formation.

  • Patent number: 6915847
    Abstract: A test technique and mechanism includes lowering a junction assembly to a junction between at least two bores of a well. The junction assembly includes one or more sealed connections that are tested by the generation of a test flow of fluid. The distal ends of the junction assembly are blocked so that a pressure increase in the junction assembly can be monitored. The level of this pressure increase is used to determine if there is any leakage in the junction assembly. To reduce the costs associated with a faulty junction assembly, the testing is performed during an installation procedure of the junction assembly. Thus, if a faulty junction is detected, it can be quickly removed and replaced with another junction assembly.

  • Patent number: 6725924
    Abstract: A system that is usable in a subsea well includes a tubular string that extends from a surface platform toward the sea floor. The string has an upper end and a lower remote end that is located closer to the sea floor than to the platform. At least one sensor of the system is located near the remote end of the string to monitor deployment of subsea equipment.
