A frac dart including a pressure housing, a mechanically actuated magnetic sensor including a first magnet outside of the pressure housing, a signal generator inside the pressure housing and in operable communication with the first magnet, and an electrical counter disposed in the frac dart responsive in increments to the signal generator.

Frac dart, method, and system

A frac dart including a pressure housing, a mechanical sensor disposed through the pressure housing, a contactor inside the pressure housing and in operable communication with the mechanical sensor, and an electrical counter disposed in the pressure housing and responsive in increments to movement of the mechanical sensor that closes the contactor.

A downhole robotic shuttle includes multiple modules coupled together in series to be conveyed through a cased geologic borehole. One or more of the modules includes: a coupling mechanism to couple one module to an adjacent module, a movement mechanism to enable conveyance of the module having the movement mechanism through the cased borehole; a steering mechanism to steer the module comprising the steering mechanism to achieve a selected orientation within the cased borehole; a motor configured to power the movement mechanism and/or the steering mechanism; an actuator to perform a selected action; a sensor to sense a selected parameter; a memory to receive instructions for performing at least one of the selected action and another action; and a controller to control at least one of the motor, steering mechanism, robotic arm, or sensor in accordance with the instructions received from the memory and sensed data received from the sensor.

Downhole robotic shuttle for performing programed operations

A downhole flow meter includes a body including an inlet exposed to downhole fluids, an impeller rotatably supported in the body, the impeller including at least one vane, at least one magnet mounted to the at least one vane, and a switch responsive to the at least one magnet arranged in the body.

Flow meter and method for measuring fluid flow

The position of a movable downhole component such as a sleeve in a choke valve is monitored and determined using an array of sensors, preferably Hall Effect sensors that measure the strength of a magnetic field from a magnet that travels with the sleeve. The sensors measure the field strength and output a voltage related to the strength of the field that is detected. A plurality of sensors, with readings, transmits signals to a microprocessor to compute the magnet position directly. The sensors are in the tool body and are not mechanically coupled to the sleeve. The longitudinal position of the sleeve is directly computed using less than all available sensors to facilitate the speed of transmission of data and computation of actual position using known mathematical techniques.
