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.
Claims20
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, such that when the fluid communication is unblocked the sensor can measure a parameter of the production fluid.

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.
