  • Patent number: 10392912
    Abstract: Estimates of global total “liquid” hydrocarbon resources are dominated by structures known as oil sands or tar sands which represent approximately two-thirds of the total recoverable resources. This is despite that the Canadian Athabasca Oil Sands, which dominate these oil sand based recoverable oil reserves at 1.7 trillion barrels, are calculated at only a 10% recovery rate. However, irrespective of whether it is the 3.6 trillion barrels recoverable from the oil sands or the 1.75 trillion barrels from conventional oil reservoirs worldwide, it is evident that significant financial return and extension of the time oil as resource is available to the world arise from increasing the recoverable percentage of such resources. According to embodiments of the invention pressure differentials are exploited to advance production of wells, adjust the evolution of the depletion chambers formed laterally between laterally spaced wells to increase the oil recovery percentage, and provide recovery in deeper reservoirs.

  • Patent number: 10385676
    Abstract: Configurations of tools, e.g., as used in the tool strings of electrical submersible pump systems, that prevent the separation of the tool string into two disconnected units upon breaking of a tool within the tool string. In an example configuration, such a non-parting tool includes a head and base connected to each other via a housing and a shaft extending through the tool, as well as mechanical stops affixed to the shaft that limit, upon breaking of the housing, the relative motion between the head and base.

  • Patent number: 10385631
    Abstract: The invention relates to a drilling vessel comprising a drilling tower and a tubular string support structure for supporting a tubular string in the firing line of the drilling tower. The tubular string support structure has two parallel rails and two carts supported by those rails. Both carts have a hanger body with a central passage for supporting a tubular, and each cart can be moved between a central support position for supporting a tubular in the firing line, and a secondary position adjacent the central support position. When both carts are located in their secondary position, the carts are located on opposite sides of the firing line, such that between the carts there is a passage for passing through large objects along the firing line.

  • Patent number: 10358883
    Abstract: A downhole tool assembly includes a downhole tool and an anchor. The anchor is positionable at a downhole work site and includes a wet-connect port for engaging a battery pack. The tool operates until the battery runs low on power, when a low battery power alert is activated. The tool may be anchored at the work site while the battery is disconnected and retrieved to the surface for replacement. One or more charged batteries are then deployed and connected to the tool without having to remove the tool from the worksite or reposition the tool. The tool may be coupled to a wireline cable or a slickline cable or coiled tubing having a conductive wire for delivering low-voltage power to the tool. While the low-voltage power may not be adequate to operate the tool at full load, the power may be used to charge the tool during downtime.
