Abstract
A system for measuring a formation parameter, the system including: a formation parameter test device having: a structure capable of segregating a discrete volume including a formation interface surface within a well, and a parameter sensor in operable communication with the volume; a high bandwidth communications system in operable communication with the parameter sensor; and a processing unit in operable communication with the high bandwidth communications system and disposed remotely from the parameter sensor, the processing unit configured to receive parameter data.
Claims21
A system for measuring a formation parameter, the system comprising:
- a formation parameter test device including:
- a structure extendable from the formation parameter test device to contact a formation interface surface within a well, the structure segregating a discrete volume defined by the structure and the formation interface surface therein, and
- a parameter sensor in operable communication with the volume and configured to measure the formation parameter data from the discrete volume;
- a high bandwidth communications system in operable communication with the parameter sensor;
- and
- a processing unit in operable communication with the high bandwidth communications system and disposed remotely from the parameter sensor at an earth surface location, the processing unit configured to receive the formation parameter data, the processing unit being configured to transmit a start signal and a stop signal from the earth surface location to the parameter sensor, wherein
- a travel time of the formation parameter data from the parameter sensor to the processing unit is less than a time period for completing a formation parameter test, and the processing unit being further configured to transmit a signal to the parameter sensor to alter a next formation parameter test by the parameter sensor based on data from the formation parameter test currently being conducted.
A method for measuring a formation parameter, the method comprising:
- extending a structure from a formation parameter test device to contact a formation interface surface within a well;
- isolating a discrete volume defined by the structure after it has been extended and the formation interface surface;
- performing a measurement of the formation parameter within the discrete volume with a parameter sensor of the formation parameter test device in operable communication with the discrete volume;
- and
- transmitting in real time the measurement from the parameter sensor to a processing unit disposed remotely from the sensor at an earth surface location;
- and
- receiving, at the formation parameter test device from the earth surface location of the processing unit, a start signal and a stop signal to the parameter sensor for the performing the measurement, wherein
- a travel time for a command signal from the processing unit to the formation parameter test device is less than a time period for performing a formation parameter test and the command signal commands the parameter sensor to alter a next formation parameter test based on data from the formation parameter test currently being conducted.
