SWEPT Technology was developed for the Enhanced Oil Recovery (“EOR”) of heavy oil assets and is based on the impact on a productive stratum by cumulative waves in the radius of several well spacings. Science tells us that hydrocarbons that are caught in wave fields decrease in viscosity and become more liquid due to the thixotropy effect, which also decreases the density of heavy oil.
SWEPT Technology is applied via a specially constructed wellhead that generates cumulative waves of various shapes, amplitudes and lengths to the productive stratum. Wave propagation in-situ can extend the length of a many well spacing, with recorded distances between 100 m to 1000 m and possibly even further based on the characteristics of the stratum. As the result of wave application, certain changes occur in the oil containing rock as well as the oil contained in those rocks.
Five - Effects of Treatment to Surrounding Stratum
- Increase of Oil Saturation resulted in micro-fracturing
- Increase In Permeability by a dilatancy effect in the massif of treated rock
- Fluid Migration Drive by Capillary Forced
- Decrease of Viscosity
- In-Situ Gasification - Upgrade
The effects of SWEPT are typically enjoyed by a well for a length of 3-5 days, to realize the most efficient production the well should be retreated repeatedly. The effect on rock properties stays for indefinite time.
Furthermore SWEPT can be applied to overcome some of the industries most common obstacles, such as, low energy, high viscosity, low permeability and porosity and high water cut along with low oil saturation.
