Yes, as long as we can cause the microbes in the reservoir to be contacted by the nutrient mixture, the effect will be positive. Waterflood operations are the easiest method to introduce the nutrients to the reservoir. The Titan Process nutrients are simply added into the injection water stream. To do this, no capital equipment is needed and the Titan Process gets to work right away. In a natural water drive, the benefit will be dependent on the movement and flow of the natural drive (generally from aquifer behavior). It may be possible to introduce the nutrients through a “watered-out” producer, but additional (or new) pumping equipment may be required. Natural water drives have not been tested sufficiently to make a definitive statement, but there is certainly promise for a successful treatment.
