  • Patent number: 8040250
    Abstract: A technique usable with a well includes disposing a retractable line in a conduit having an open end located above a region of interest in the well. The retractable line comprises a sensing portion that, when the line is deployed, extends from the open end of the conduit and into the region of interest. Information observed by the sensing portion in the region of interest is communicated to the surface. When further well operations are to be performed in the region of interest, the retractable line is retracted until the sensing portion is located above the region of interest and below the surface. After the well operation is completed, the retractable line may be re-deployed such that the sensing portion again extends through the open end of the conduit and into the region of interest to continue observing characteristics associated with the well.

  • Patent number: 7278480
    Abstract: A sensor plug positionable in a perforation extending into a wall of a wellbore penetrating a subterranean formation is provided. The sensor plug includes a plug sleeve disposable in a perforation extending through the wellbore wall, a pin positionable in the plug sleeve a sensor and circuitry. The pin is adapted to expand the plug sleeve as it is advanced therein whereby the plug sleeve seals the perforation. The sensor plug may be deployed into the sidewall of the wellbore by a downhole tool.

  • Patent number: 6766854
    Abstract: The present invention relates to a well-bore sensor apparatus and method. The apparatus includes a downhole tool carrying at least one sensor plug for deployment into the sidewall of a well-bore. The apparatus may also be used in conjunction with a surface control unit and a communication link for operatively coupling the sensor plug to the surface control unit. The sensor plug is capable of collecting well-bore data, such as pressure or temperature, and communicating the data uphole via a communication link, such as the downhole tool or an antenna. The downhole data may then be analyzed and control commands sent in response thereto. The sensor plug and/or the downhole tool may be made to respond to such control commands. In some embodiments, multiple surface control units for corresponding wells may be networked for decision making and control across multiple well-bores.

  • Patent number: 6561274
    Abstract: A system for unloading fluids from a generally upright tubular member of a wellbore wherein a combustible fuel cell can be placed in the tubular member below the fluid and ignited to generate gasses. The gasses generated by the burning of the fuel cell can be used to force at least a portion of the fluid upward out of the tubular member.

  • Patent number: 6478090
    Abstract: An apparatus and method of operating devices (such as devices in a wellbore or other types of devices) utilizes actuators having expandable or contractable elements. Such expandable or contractable elements may include piezoelectric elements, magnetostrictive elements, and heat-expandable elements. Piezoelectric elements are expandable by application of an electrical voltage; magnetostrictive elements are expandable by application of a magnetic field (which may be generated by a solenoid in response to an electrical current); and heat-expandable elements are expandable by heat energy (e.g., infrared energy or microwave energy). Expandable elements are abutted to an operator member such that when the expandable element expands, the operator member is moved in a first direction, and when the expandable element contracts, the operator member moves in an opposite direction.

  • Patent number: 6467387
    Abstract: An apparatus and method are provided for deploying a data sensing apparatus into a subsurface geologic formation for intermittent or continuously gathering data from the subsurface formation and transmitting the data to a remote data receiver. In a preferred embodiment, a non-linear arrangement of a barrel and a burn chamber is used to provide a gun-like device for firing a bullet-shaped data sensing apparatus into a formation of interest. The data sensing apparatus, once disposed within the matrix of the formation of interest, monitors formation conditions and transmits the data for use in optimizing drilling and production activities.
