Abstract
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.
