Conclusions
The application of technologies in mature producing basins can result in improving marginal well economics, thus prolonging their life. Improving economics is accomplished by reducing lifting costs, recovering additional reserves, or a combination of both. The application of gel polymer treatments on Arbuckle wells in Kansas is a good example of revitalizing mature marginal production through technology application.
