Patent number: 9518440Abstract: A bridge plug with a selectively blocked flow passage is delivered on wireline and pumped down to the desired location and set. A casing pressure test can be performed above the bridge plug while shielding the formation below from excess pressure from the pressure test. To the extent there are producing zones below the bridge plug or adjacent injection wells that could communicate with the borehole, the plug isolates those pressures from below. After the pressure test is completed, a rupture disc is blown in a passage through the bridge plug and flow is then used to deliver completion equipment to a horizontal portion of the borehole and preferably on wireline.Type: GrantFiled: April 8, 2014Date of Patent: December 13, 2016Assignee: Baker Hughes IncorporatedInventors: James S.

Patent number: 8583326Abstract: A GNSS-based contour guidance path selection system for guiding a piece of equipment through an operation, such as navigating a guide path, includes a processor programmed for locking onto a particular aspect of the operation, such as deviating from a pre-planned or original guidance pattern and locking the guidance system onto a new route guide path, while ignoring other guidance paths. The system gives a vehicle operator control over a guidance route without the need to re-plan a pre-planned route. The device corrects conflicting signal issues arising when new swaths result in the guidance system receiving conflicting directions of guidance where the new swaths cross predefined swaths. An operator can either manually, or with an autosteer subsystem automatically, maintain a new contour guidance pattern, even while crossing predefined guidance paths that would otherwise divert the vehicle.Type: GrantFiled: February 9, 2010Date of Patent: November 12, 2013Assignee: AgJunction LLCInventors: Dennis M.

Patent number: 8548649Abstract: A GNSS system in combination with a hydraulically-actuated, airborne dispenser for a dry material crop dusting system to optimize the distribution of dry materials over a particular tract of land. A GNSS subsystem is included using at least one GNSS antenna and one GNSS receiver located on the aircraft. The aircraft is equipped with an electronic/hydraulic crop dusting subsystem connected to a GNSS CPU. The GNSS ranging signals received by the antennas are processed by a receiver and processor system for determining the vehicle's position and dynamic attitude in three dimensions (3D). A graphical user interface (GUI) placed in the vehicle will give the driver a real-time view of his or her current bearing as well as a calculated “optimal path” based on calculations and variable data, such as wind speed and direction, material moisture content, altitude, air speed and other conditions. The system is adapted for operation in a differential GNSS (DGNSS) mode utilizing a base station at a fixed location.Type: GrantFiled: October 19, 2010Date of Patent: October 1, 2013Assignee: AgJunction LLCInventors: Greg S.

Patent number: 8018376Abstract: A GNSS-based, bidirectional mobile communication system includes a mobile unit, such as a vehicle or a personal mobile system, with GNSS (e.g., GPS) and Internet (worldwide web) access. A base station also has GNSS and Internet access, and provides differential (e.g., DGPS) correctors to the mobile unit via the Internet. The Internet communications link enables audio and/or video (AV) clips to be recorded and played back by the mobile unit based on its GNSS location. The playback function can be triggered by the mobile unit detecting a predetermined GNSS location associated with a particular clip, which can be GNSS position-stamped when recorded. Alternatively, clips can be generated by utilities and loaded by the application either from a personal computer or automatically over the Internet. Moreover, maps, vehicle travel paths and images associated with particular GNSS-defined locations, such as waypoints, can be updated and position-stamped on the data server.Type: GrantFiled: April 6, 2009Date of Patent: September 13, 2011Assignee: Hemisphere GPS LLCInventors: John A.
