    Abstract: A method and apparatus for completing a well that includes a subsurface barrier valve utilizes an injection valve which includes a variable orifice insert. The injection valve includes a mechanism for sensing pressure cycles that are employed during various well completion operations including pressure testing. The mechanism includes an indexing sleeve which will disable pressure functionality. Once this occurs, pressure cycling to open the barrier valve can proceed. Once the barrier valve opens, flow alone controls the injection valve during normal operations.

    Abstract: A jarring tool includes a spring and a hydraulic piston cylinder arrangement for controlling the release of a mandrel to initiate a jarring force. The tool includes an adjustment mechanism for adjusting the minimum amount of an upward pulling force required to release the mandrel. The adjustment mechanism includes an axially adjustable trigger sleeve that cooperates with a dog clutch surrounding the mandrel.

    Abstract: A user-initiated data recognition and data conversion process allows for the conversion of unstructured data to structured data from a capture of an optical character recognition image with the unstructured data underneath. A method for converting unstructured data to structured data includes uploading a digital representation of a document to an optical character recognition server, scaling the digital representation of the document to fit the display size of a mobile device, using a touch interface to select unstructured data from the scaled digital representation of the document, populating the selected unstructured data in an electronic record to create structured data, and storing the structured data on a remote server.

    Abstract: A system and method allowing for the transfer of heat from a heating element in a tube heating system to production tubing in downhole pipes. The heating tube is comprised of double walled and double threaded pipe. The transferred heat warms the material being extracted from a subterranean formation and collected at the surface. Warming the material prevents the build-up of paraffins, asphaltenes, or other materials that may potentially clog production pipe in downhole applications.
