The growing environmental concerns related to water usage in unconventional hydrocarbon extraction necessitate the development of alternative fracturing methods. This work evaluates CO2-based fracturing as a sustainable development approach for shale gas reservoirs in the Burgos Basin of Mexico. The results demonstrate that CO2 fracturing represents both an environmentally sustainable and economically viable alternative to conventional methods for shale reservoir development in water-stressed regions.

Introduction

The Burgos Basin represents Mexico’s most significant gas resource, with estimated reserves of 421 Tscf of wet gas and 348 Tscf of dry gas. To date, 27 wells have been drilled for unconventional resources in the basin, with estimated initial production rates of 6 MMscf/D and prolonged production decline curves.
