US Patent:

20180094518, Apr 5, 2018

Filed:

Nov 22, 2017

Appl. No.:

15/820919

Inventors:

Franck T. Kpetehoto - Spring TX, US
James Albert Hood - Houston TX, US
Stephen Carey - Conroe TX, US

Assignee:

Baker Hughes, a GE company, LLC - Houston TX

International Classification:

E21B 44/02

Abstract:

A method for drilling a borehole penetrating the earth includes: inputting drilling parameters as a function of depth used to drill one or more offset boreholes and rate of penetration using the drilling parameters, any drilling dysfunctions that occurred using the drilling parameters, and one or more lithologies as a function of depth for the one or more offset boreholes. The method also includes identifying those drilling parameters that correspond to a rate of penetration (ROP) that meets or exceeds an ROP threshold for each input lithology and a minimum number of drilling dysfunctions or minimum magnitude of a drilling dysfunction to provide identified drilling parameters; correlating a borehole plan comprising a borehole path and one or more assumed lithologies as a function of depth to the one or more lithologies of the one or more offset boreholes; and drilling the borehole with the drill rig using the identified drilling.

Abstract:

A method implemented by a processor for drilling a borehole includes: inputting drilling parameters used to drill one or more offset boreholes, rate of penetration for the one or more offset boreholes, and one or more lithologies for the one or more offset boreholes; identifying those drilling parameters that correspond to a rate of penetration (ROP) that meets or exceeds a selected ROP threshold for each input lithology; correlating a borehole plan comprising a borehole path to be drilled and one or more assumed lithologies as a function of depth to the one or more lithologies of the one or more offset boreholes; sending the identified drilling parameters to a drill rig controller for each of the assumed lithologies in the borehole plan; and drilling the borehole with the drill rig using the identified drilling parameters for each of the one or more assumed lithologies in the borehole plan.
