Patent ID: 7875455

Claim:
A system for monitoring and evaluating status of an array of one or more underground mineral-producing wellsites, the system comprising: a first chip comprising: (i) a first nanosensor to estimate H 2 O content present in the wellsite; and (ii) a second nanosensor to estimate presence or absence of each of at least first and second different target gas molecules in the wellsite; a second chip containing (iii) a temperature microsensor to estimate local temperature in an underground fluid mineral-producing wellsite; and at least one of: (iv) a pressure microsensor to estimate local fluid pressure adjacent to the wellsite; (v) a distance microsensor to provide an estimate of distance to each of at least two spaced apart surfaces bounding the fluid mineral in the wellsite; (vi) a fluid flow microsensor to estimate at least one of flow direction and flow velocity of a fluid adjacent to the wellsite; and a wireless data transmission mechanism to receive and process data from the first and second nanosensors and from the at least one microsensor, and to transmit the processed data to a receiver spaced apart from the data transmission mechanism.
