Abstract
A method and apparatus for determining a parameter of a production fluid in a wellbore by providing an initially blocked isolated communication path between a sensor and an aperture formed in a sleeve. The isolated communication path is subsequently unblocked to allow measurements of the parameter of the production fluid.
Claims19
A tool string for determining a parameter of a production fluid in a wellbore, comprising:
- a tubing having an opening;
- a sensor coupled to the tubing;
- and
- an isolated communication path providing fluid communication between the sensor and the opening, wherein the isolated communication path includes a removable seal positioned between a bore of the tubing and the sensor to initially block fluid communication therebetween.
A method for determining a parameter of a production fluid in a wellbore, comprising:
- coupling a sensor to a string of tubing having an opening;
- inserting the string of tubing into the wellbore while an isolated communication path between the sensor and the opening is blocked;
- cementing the string of tubing in the wellbore;
- injecting a fracking fluid into a formation adjacent the wellbore, thereby perforating the cement;
- unblocking the isolated communication path between the sensor and the opening;
- and
- measuring the parameter of the production fluid with the sensor.
The method of claim 19, wherein the removable seal is disposed within the port, wherein the removable seal is at least one of a removable pluge and a burst disc.
