  • Patent number: 11863980
    Abstract: A System Platform establishes a Genuine User ID (“GUID”), creates a user profile for an Intended User, generates a unique data set based upon input associated with the user profile and a digital device it has registered to the Intended User. The output of the GUID in combination with the output of an algorithm in a provisioning application enables the digital device to respond to Access Requests at an Access Point. The response from the genuine Intended User's application on their genuine digital device produces a unique data package which combines the GUID, a device ID for the digital device and the output of the algorithm using the payload obtained from one or more data management sources. The unique data package can be tailored for many different uses by the intended user, including uses which are attended or unattended, with varying levels of security.

  • Patent number: 10415365
    Abstract: A method of controlling a direction of drilling of the drill string used to form an opening in a subsurface formation, comprises varying a speed of the drill string during rotational drilling such that the drill string is at a first speed during a first portion of the rotational cycle and at a second speed during a second portion of the rotational cycle wherein the first speed is higher than the second speed, and wherein operating at the second speed in the second portion of the rotational cycle causes the drill string to change the direction of drilling.

  • Patent number: 9683418
    Abstract: The present disclosure provides a method for picking up a drill bit off the bottom of an opening in a subsurface formation. The method includes setting a predetermined level of differential pressure across a mud motor at which pickup of the drill bit is to be initiated, and monitoring the differential pressure across the mud motor. The method also includes allowing differential pressure across the mud motor to decrease to the predetermined level, and when the predetermined level is reached, automatically picking up the drill bit.
