EETCT and related technologies were tested on over a hundred, mostly several decades old, heavily-watered, and shut-in wells in Russia. The results far exceeded our expectations. Production increased by at least double and, in some cases, as much as fifteen-fold, compared to pre-treatment values.
In Texas, USA, we applied a predecessor of EETCT on a well that had been shut down since 1999, with a 99.5% water-to-oil ratio (WOR). When the well was originally opened in 1994, initial production was 35 barrels per day, gradually decreasing to zero, despite all efforts to push the oil to neighboring wells. After the EETCT treatment, the well immediately produced 38 barrels of oil per day, and the WOR was reduced to below 60%. After several days of increased production, the well was closed again and the demo was evaluated as a success.
At a recent demonstration in the north of Russia on an old, non-productive well for Lukoil, we pumped approx. 20 tons of chemical reagents continuously into the well over several hours. We calculated that some 75 GJ of heat was released, and the chemicals all converted into gases. Temperatures quickly reached the target value, slightly above 300°C (600°F), and were maintained at this level, entirely at our control.
The well produced 695 extra tons of oil over the next 90 days, resulting in a net profit reaching almost USD 1M within one year. Two years after treatment, production still remained 30-40% above pre-treatment levels.
This large-scale demonstration proves that we are able to quickly and safely pump a (practically) unlimited amount of reagents, while fully regulating the process.
Old, shut-in wells can be re-opened and made productive again. The increase in production continues steadily for many months, up to two years, and it continues to be relatively high even when the collector cools down. The well is then ready for another EETCT treatment to increase production again.
Soon we will be ready to demonstrate our technology on your oil field, anywhere in the world.
