  • Patent number: 10253971
    Abstract: A system for generating high pressure steam from dirty water uses a combination of sub-merged plasma arcs and electrical resistive heating. Dirty water from steam assisted gravity drainage, or other dirty water producing process, which needs to be converted into high pressure steam, is fed directly without any pre-treatment, into a plasma fired steam generator, powered by submerged electrodes. The combination of electric arc plasma and resistive heating is created between the submerged electrodes. The heat so generated will boil the water portion of the dirty water feed to generate steam that is collected in a steam space and then removed there from. The solids and other residues (residual sludge) present in the feed water settle down at the bottom of the steam generator and are removed via a blow-down stream. The plasma arcs are used to intermittently remove any scaling or solid deposits that can accumulate on the electrodes.

  • Patent number: 9574823
    Abstract: A method for recovering natural gas liquids without using cryogenic conditions, membranes, and carbon dioxide recovery solvents is provided. In one embodiment, a carbon dioxide recycle stream that comprises carbon dioxide and natural gas liquids is received. The carbon dioxide recycle stream is separated into a purified carbon dioxide recycle stream and a natural gas liquids stream. The purified carbon dioxide recycle stream comprises the carbon dioxide, and the natural gas liquids stream comprises the natural gas liquids. The carbon dioxide recycle stream, the purified carbon dioxide recycle stream, and the natural gas liquids are not subjected to cryogenic conditions, membranes, and carbon dioxide recovery solvents between being received and being separated into the purified carbon dioxide recycle stream and the natural gas liquids stream.

  • Patent number: 9121257
    Abstract: The present invention provides a method and system for providing on-site electrical power to a fracturing operation, and an electrically powered fracturing system. Natural gas can be used to drive a turbine generator in the production of electrical power. A scalable, electrically powered fracturing fleet is provided to pump fluids for the fracturing operation, obviating the need for a constant supply of diesel fuel to the site and reducing the site footprint and infrastructure required for the fracturing operation, when compared with conventional systems.

  • Patent number: 9097110
    Abstract: Methods for recovering viscous oil include receiving electrical power from an electrical grid fed by at least one fluctuating electricity supply. The methods also include using at least a portion of the received electrical power to heat a first fluid stream using an electrical heater. The methods also include heating a second fluid stream with a fired-heater using a combustible fuel. The methods further include using both the first and second heated fluid streams to aid oil recovery. In accordance with these methods, the heat output of the electrical heater is adjusted during production operations to at least partially match an estimated mismatch between electrical power supply from and demand on the grid. At the same time, the heat output of the fired-heater is adjusted to at least partially compensate for fluctuations in the electrical heater heat output.
