Patent number: 10415365Abstract: 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.Type: GrantFiled: May 24, 2017Date of Patent: September 17, 2019Assignee: SHELL OIL COMPANYInventors: David Alston Edbury, Jose Victor Guerrero, Duncan Charles Macdonald, James Bryon Rogers, Donald Ray Sitton, Jason B. Norman

Patent number: 9879490Abstract: A method of automatically placing a drill bit used to form an opening in a subsurface formation on a bottom of the opening being formed comprises a) increasing a flow rate in a drill string to a target flow; b) controlling a flow rate of fluid into the drill string to be substantially the same as a flowrate of fluid out of the opening; c) allowing a fluid pressure to reach a relatively steady state; and d) automatically moving the drill bit toward the bottom of the opening at a selected rate of advance until an increase in measured differential pressure indicates that the drill bit is at the bottom of the opening.Type: GrantFiled: October 11, 2012Date of Patent: January 30, 2018Assignee: SHELL OIL COMPANYInventors: David Alston Edbury, Jose Victor Guerrero, Duncan Charles MacDonald, James Bryon Rogers, Donald Ray Sitton, Jason B.

Patent number: 9683418Abstract: 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.Type: GrantFiled: October 11, 2012Date of Patent: June 20, 2017Assignee: Shell Oil CompanyInventors: David Alston Edbury, Jose Victor Guerrero, Duncan Charles MacDonald, James Bryon Rogers, Donald Ray Sitton
