A downhole communications system comprises a power generator disposed proximate a predetermined portion of a side pocket mandrel in such a way as to not impede fluid flow within a wellbore into which the side pocket mandrel is disposed and a wireless communications transmitter operatively in communication with the power generator. Placed at least partially within a side pocket mandrel, the system allows fluid flowing proximate the side pocket mandrel to engage the power generator to create electric energy which may be used to power the wireless communications transmitter and allow data interchange between the wireless communications transmitter and a predetermined well device.

An example method includes positioning a first conformable sensor proximate to a downhole element. The first conformable sensor may include a flexible material, with first and second transmitters and first and second receivers coupled to the flexible material. A first signal may be generated using the first transmitter and a second signal using the second transmitter. A first response of the downhole element to the first signal and a second response of the downhole element to the second signal may be measured at the first receiver. A third response of the downhole element to the first signal and a fourth response of the downhole element to the second signal may be measured at the second receiver. At least the first, second, third, and fourth responses may be combined into a compensated response of the downhole element. The compensated response may be processed to determine a parameter of the downhole element.
