  • Hydrocarbon extraction tool and pump assemblies
    Patent number: 10316630
    Abstract: A novel tool for improving the efficiency of extraction of hydrocarbons from underground formations is described. The tool is configured to produce localized waves of high pressure fluid at a location within a wellbore. These pressure waves are effective to displace hydrocarbons within a geological formation such that enter the interior of the wellbore where they can be more easily removed by means of an accompanying pump assembly.
    Type: Grant
