Abstract
Apparatus and methods for determining downhole fluid parameters are disclosed herein. An example method includes deploying a downhole apparatus into a wellbore. The downhole apparatus includes a sensor including a heater and a temperature sensor. The example method also includes sending a signal to a downhole apparatus by changing a velocity of a fluid traversing the wellbore. The example method also includes detecting a change in the velocity of the fluid with the sensor and operating the downhole apparatus based on the change in velocity.
Claims20
A method, comprising:
- placing a sensor including a heater and a temperature sensor in a conduit;
