  • Graph to analyze drilling parameters
    Patent number: 8854373
    Abstract: A method for presenting drilling information includes presenting a display including a graph having a first axis and a second axis. The first axis represents a rate of penetration (ROP) of a drill bit into a borehole and the second axis representing a mechanical specific energy (MSE) of a drilling system that includes the drill bit. The method also includes plotting time based or foot based data with a computing device for one or more drilling runs on the graph and overlaying the graph with lines of constant power.
    Type: Grant
    Filed: March 8, 2012
    Date of Patent: October 7, 2014
    Assignee: Baker Hughes Incorporated
    Inventors: Rudolf C. Pessier, Stephen Nicholas Wallace, Hatem Oueslati
