Abstract
Apparatus, methods for forming the apparatus, and methods for operating the apparatus provide a modular unit of hardware to make measurements in a well. The modular unit may include a housing arranged for placement in a drill-string element, where the housing includes a sensor and is structured such that the housing is transferable to another drill-string element without a calibration of the sensor during or after the transfer. The drill-string elements associated with the transfer may be of different sizes.
Claims30
A system comprising:
- a housing arranged for placement with a drill-string element, the housing being a modular unit of hardware to make measurements in a well;
- and
- at least one sensor disposed in the housing, the at least one sensor and the housing calibrated to form a calibrated sensor housing and such that the calibrated sensor housing is transferable to another drill-string element without a calibration of the at least one sensor during or after the transfer.
A method comprising:
- calibrating a combination of at least one sensor disposed in a sensor housing and a measurement source, the sensor housing being a modular unit of hardware to make measurements in a well such that the sensor housing is configured to transfer among different drill-string elements without calibrating the at least one sensor during or after the transfer.
A method comprising:
- making a first set of measurements in a well, the measurements made using at least one sensor disposed in a calibrated sensor housing in a first drill-string element, the calibrated sensor housing configurable for transfer among different drill-string elements without calibrating the at least one sensor during or after the transfer;
- transferring the calibrated sensor housing having the at least one sensor to a second drill-string element without performing a calibration of the at least one sensor during or after the transfer;
- making a second set of measurements, the second set of measurements made using the at least one sensor disposed in the calibrated sensor housing in the second drill-string element.
A method comprising:
- constructing a housing to mate to a drill-string element;
- attaching at least one sensor into the housing, the at least one sensor and the housing calibrated to form a calibrated sensor housing;
- attaching electronics in the housing, the electronics arranged to store and access calibration information to transfer the calibrated sensor housing to another drill-string element without calibration of the at least one sensor during or after the transfer.
A machine-readable medium that stores instructions, which when performed by a machine, cause the machine to:
- collect a first set of measurements, the measurements performed in a calibrated sensor housing in a first drill-string element, the calibrated sensor housing having at least one sensor disposed therein;
- apply calibration information associated with transfer of the calibrated sensor housing to a second drill-string element;
- and
- collect a second set of measurements, the measurements performed in the calibrated sensor housing in the second drill-string element.
