ABSTRACT:
The invention relates to a system and method for sensing the characteristics of a fluid in a sub-surface formation. In one embodiment, the invention relates to a sensor apparatus for sensing a chemical in a vapor emitted by a sub-surface fluid sample. In various configurations, the apparatus senses the presence and/or percentage of water, the presence of a gas, an oil/gas ratio, an aliphatic/aromatic hydrocarbon ratio, and/or the presence of corrosive or poisonous chemicals.
