Abstract
A method of evaluating an operation of a downhole motor implemented in a wellbore includes receiving a first set of downhole data associated with the operation of the downhole motor at a first flowrate and generating a flowrate-independent power curve for the downhole motor based on the first set of downhole data. The method further includes, based on the flowrate-independent power curve, determining a second set of downhole data associated with the operation of the motor at a second flowrate.

A method of evaluating an operation of a downhole motor implemented in a wellbore, comprising:
- receiving a set of downhole data associated with the operation of the downhole motor at a first flowrate;
- generating a flowrate-independent power curve for the downhole motor using the set of downhole data by fitting a flowrate-independent power law model to the set of downhole data and solving the flowrate-independent power law model for model parameters of the flowrate-independent power law model at the first flowrate;
- generating, using the flowrate-independent power curve, new operational parameters for the downhole motor to transition to a new flowrate by solving the flowrate-independent power law model for the new operational parameters at the new flowrate;
- and
- adjusting the downhole motor to the new generated operational parameters to operate at the new flowrate.
A system, comprising:
- at least one processor;
- memory in electronic communication with the at least one processor;
- and
- instructions stored in the memory, the instructions being executable by the at least one processor to:
- receive a set of downhole data associated with an operation of a downhole motor at a first flowrate;
- generate a flowrate-independent power curve for the downhole motor using the set of downhole data by fitting a flowrate-independent power law model to the set of downhole data and solving the flowrate-independent power law model for model parameters of the flowrate-independent power law model at the first flowrate;
- generate, using the flowrate-independent power curve, new operational parameters for the downhole motor to transition to a new flowrate by solving the flowrate-independent power law model for the new operational parameters at the new flowrate;
- and
- provide instructions to the downhole motor to adjust the downhole motor to the new generated operational parameters to operate at the new flowrate.
A non-transitory computer-readable storage medium including instruction that, when executed by at least one processor, causes the processor to:
- receive a set of downhole data associated with an operation of a downhole motor at a first flowrate;
- generate a flowrate-independent power curve for the downhole motor using the set of downhole data by fitting a flowrate-independent power law model to the set of downhole data and solving the flowrate-independent power law model for model parameters of the flowrate-independent power law model at the first flowrate;
- generate, using the flowrate-independent power curve, new operational parameters for the downhole motor to transition to a new flowrate by solving the flowrate-independent power law model for the new operational parameters at the new flowrate;
- and
- adjust the downhole motor to the new generated operational parameters to operate at the new flowrate.
