Abstract
A system and method that may include receiving real-time downhole data from one or more sensors of a drillstring disposed in a borehole in a subsurface geologic region during a directional drilling operation. The system and method also include selecting a drillstring drilling mode from a plurality of drillstring drilling modes. The system and method may additionally include predicting, in real-time, characteristics of a hole bottom of the borehole using the drilling mode model and at least a portion of the real-time downhole data. The system and method may further include controlling the directional drilling operation using one or more of the characteristics.
Claims20
A method comprising:
- receiving real-time downhole data from one or more sensors of a drillstring disposed in a borehole in a subsurface geologic region during a directional drilling operation, wherein a drill bit of the drillstring breaks rock of the subsurface geologic region to lengthen the borehole;
- selecting a drillstring drilling mode from a plurality of drillstring drilling modes, wherein the drillstring drilling mode comprises an associated drilling mode model for the directional drilling operation;
- predicting, in real-time, characteristics of a hole bottom of the borehole using the drilling mode model and at least a portion of the real-time downhole data;
- and
- controlling the directional drilling operation using one or more of the characteristics.
A system comprising:
- one or more processors;
- memory accessible to at least one of the one or more processors;
- processor-executable instructions stored in the memory and executable to instruct the system to:
- receive real-time downhole data from one or more sensors of a drillstring disposed in a borehole in a subsurface geologic region during a directional drilling operation, wherein a drill bit of the drillstring breaks rock of the subsurface geologic region to lengthen the borehole;
- select a drillstring drilling mode from a plurality of drillstring drilling modes, wherein the drillstring drilling mode comprises an associated drilling mode model for the directional drilling operation;
- predict, in real-time, characteristics of a hole bottom of the borehole using the drilling mode model and at least a portion of the real-time downhole data;
- and
- control the directional drilling operation using one or more of the characteristics.
One or more non-transitory computer-readable storage media comprising processor-executable instructions to instruct a computing system to:
- receive real-time downhole data from one or more sensors of a drillstring disposed in a borehole in a subsurface geologic region during a directional drilling operation, wherein a drill bit of the drillstring breaks rock of the subsurface geologic region to lengthen the borehole;
- select a drillstring drilling mode from a plurality of drillstring drilling modes, wherein the drillstring drilling mode comprises an associated drilling mode model for the directional drilling operation;
- predict, in real-time, characteristics of a hole bottom of the borehole using the drilling mode model and at least a portion of the real-time downhole data;
- and
- control the directional drilling operation using one or more of the characteristics.
