Abstract
Example methods and apparatus for determining fluid parameters are disclosed herein. An example method includes disposing a sensor in a first fluid flow passageway. The sensor has a heater and a temperature sensor. The example method further includes flowing a first fluid into the first fluid flow passageway via a second fluid flow passageway and determining a first fluid property value of the first fluid via the sensor when the first fluid is in the first fluid flow passageway. Based on the first fluid property value, a state of an operation is determined.
Claims16
A method for performing an operation in a wellbore, comprising:
- disposing a downhole tool in a wellbore via a coiled tubing, the downhole tool including a treatment tool, a first sensor and a second sensor, the first sensor having a first heater and a first temperature sensor, the second sensor having a second heater and a second temperature sensor;
- performing the operation by flowing a treatment fluid into the wellbore from inside the coiled tubing and the downhole tool through the treatment tool;
- determining a first fluid property value of the treatment fluid via the first sensor when the treatment fluid is inside the downhole tool;
- determining a second fluid property value of the treatment fluid via the second sensor when the treatment fluid is in the wellbore outside of the downhole tool;
- determining a state of the operation based on a difference between the determined first fluid property value and the determined second fluid property value;
- and
- controlling the operation based on the determined state of the operation.
A method, comprising:
- disposing a downhole tool in a wellbore via a coiled tubing, the downhole tool including a treatment tool, a first sensor, and a second sensor, each of the sensors having a heater and a temperature sensor;
- determining a first fluid property value of a first fluid via the first sensor, the first fluid disposed in the wellbore adjacent the downhole tool;
- flowing a second fluid into the wellbore from inside the coiled tubing and the downhole tool through the treatment tool;
- determining a second fluid property value of the second fluid via the second sensor while flowing the second fluid into the wellbore;
- determining a third fluid property value of the first fluid when the second fluid is inside the downhole tool via the second sensor;
- determining a state of a downhole operation based a difference between at least one of the first fluid property value, the second fluid property value, and the third fluid property value;
- and
- controlling the downhole operation based on the determined state of the operation.
