20080302527 | String Mounted Hydraulic Pressure Generating Device for Downhole Tool Actuation - Two subs are held in a fixed position relative to each other when assembled to a string and run into a wellbore. A reservoir of fluid is defined in a wall between the subs. The reservoir has one or more outlets connected by a short jumper line to an adjacent tool to be operated. At the appropriate time, set down weight breaks a shear pin to reduce the reservoir volume and create pressure in the exit lines. The exit lines can be connected to operating pistons in adjacent tools to actuate them or to perform other desired functions using a stream of pressurized fluid. The device can be set for one time or multiple cycles where fluid in the reservoir can be replenished and re-pressurized for multiple cycles of operation. | 12-11-2008 |

20110042061 | Fiber Optic Gravel Distribution Position Sensor System - The well condition during gravel packing is monitored and the gravel distribution condition is sent to the surface in real time through the preferred technique of a fiber optic line that wraps around the screens directly or indirectly on a surrounding tube around the screens. The fiber optic line has a breakaway connection that severs when the completion inner string is removed. A production string can then be run in to tag the fiber optic line through a wet connect to continue monitoring well conditions in the production phase. The fiber optic line can also be coiled above the packer so that relative movement of the inner string to the set packer can be detected and communicated to the surface in real time so as to know that the crossover has been moved the proper distance to, for example, get it from the gravel packing position to the reverse out position. | 02-24-2011 |
