Abstract: Techniques described herein include performing a distributed device trust determination that includes determining trust scores for customer devices across multiple organizations. In one example, this disclosure describes a method that includes receiving data of a user device event including an organization confidence level for a user device associated with the user device event; updating common data in an entry for the user device in a device registry based on the received data of the user device event and the organization confidence level for the user device; determining a common confidence level for the user device based on the common data in the entry for the user device in the device registry; and outputting the common confidence level for the user device for use by the computing device of the first organization to determine how to handle an access request from the user device.

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.
