An apparatus and method are provided for gathering data from a subsurface formation. A shell is utilized having a chamber therein, and being adapted for sustaining forcible propulsion into the subsurface formation. A data sensor is disposed within the chamber of the shell. The shell has a first port therein for communicating properties of a fluid present in the subsurface formation to the data sensor when the apparatus is positioned in the subsurface formation, whereby the data sensor senses at least one of the properties of the fluid.
