Abstract
A method can include receiving data for a borehole trajectory in a formation, a length of pipe, and a bottom hole assembly that includes a mud motor and a bit; generating a sequence for operation of the mud motor using a model of at least the bit, where the sequence includes a sliding mode and a rotary mode for drilling the borehole in the formation a distance less than or equal to the length of pipe; and drilling the borehole according to the sequence.
Claims20
A method comprising:
- receiving data for a borehole trajectory in a formation, a length of pipe, and a bottom hole assembly that comprises a mud motor and a bit;
- generating a sequence for operation of the mud motor using a model of at least the bit, wherein the sequence comprises a sliding mode and a rotary mode for drilling the borehole in the formation a distance less than or equal to the length of pipe;
- and
- drilling the borehole according to the sequence.
A system comprising:
- a processor;
- memory accessible by the processor;
- processor-executable instructions stored in the memory and executable to instruct the system to:
- receive data for a borehole trajectory in a formation, a length of pipe, and a bottom hole assembly that comprises a mud motor and a bit;
- generate a sequence for operation of the mud motor using a model of at least the bit, wherein the sequence comprises a sliding mode and a rotary mode for drilling the borehole in the formation a distance less than or equal to the length of pipe;
- and
- drill the borehole according to the sequence.
One or more computer-readable storage media comprising processor-executable instructions to instruct a computing system to:
- receive data for a borehole trajectory in a formation, a length of pipe, and a bottom hole assembly that comprises a mud motor and a bit;
- generate a sequence for operation of the mud motor using a model of at least the bit, wherein the sequence comprises a sliding mode and a rotary mode for drilling the borehole in the formation a distance less than or equal to the length of pipe;
- and
- drill the borehole according to the sequence.
