Abstract
A system for monitoring an Electrical Submersible Pump is disclosed comprising a rotation rate sensor located in an ESP gauge (6). When the Electrical Submersible Pump is started the rotating elements rotate in a first direction whilst the static elements will experience an opposing torque in a second opposite direction. The small rotational movement of the ESP gauge housing is sensed by the sensor and is used to determine the initial direction of rotation of the motor (5) and pump (6).
Claims21
1-30. (canceled)
An apparatus, comprising:
- an electrical submersible pump assembly including a motor, a pump, a housing, and at least one sensor positioned to measure a rotational rate of the housing, the at least one sensor being one or more of the following:
- a rotation rate sensor, an angular rate sensor, and a rotational acceleration sensor;
- and
- a processing system being configured to determine an initial direction of rotation of the motor responsive to a signal output from the at least one sensor.
