Abstract
Methods and system are provided for measuring parameters while drilling a wellbore using a coiled tubing drilling apparatus. An exemplary system includes an instrumented mandrel including a notch in an outer surface of the instrumented mandrel, and an indentation at each end of the notch. A sensor package in the system includes a sensor, a tubular assembly, and a mounting bracket at each end of the tubular assembly. The sensor package is sized to fit in the notch, with each of the mounting brackets fitting in one of the indentations at each end of the knot, and wherein the sensor package is substantially flush with the instrumented mandrel.
Claims33
A system for measuring parameters while drilling a wellbore using a coiled tubing drilling apparatus, comprising:
- an instrumented mandrel comprising:
- a notch in an outer surface of the instrumented mandrel;
- and
- an indentation at each end of the notch;
- a sensor package, comprising:
- a sensor;
- a tubular assembly;
- and
- a mounting bracket at each end of the tubular assembly;
- wherein the sensor package is sized to fit in the notch with each of the mounting brackets fitting in one of the indentations at each end of the notch, and wherein the sensor package is substantially flush with the instrumented mandrel.
A method for assembling a bottom hole assembly for coiled tubing drilling that includes an instrumented mandrel, comprising:
- selecting a configuration for the bottom hole assembly;
- selecting a sensor for the instrumented mandrel;
- assembling a sensor package;
- mounting the sensor package on the instrumented mandrel;
- assembling the bottom hole assembly for the coiled tubing drilling;
- and
- mounting the bottom hole assembly on a coiled tubing apparatus.
A method for geosteering a wellbore using an instrumented mandrel in a bottom hole assembly on a coiled tubing drilling apparatus, comprising:
- measuring a response from a sensor disposed in a sensor package on the instrumented mandrel in the bottom hole assembly;
- determining a parameter from the response;
- logging the parameter;
- and
- determining adjustments to geosteering vectors for the bottom hole assembly based on the parameter.
