Mexico’s Energy Reform was enacted in 2013 aiming to foster competitiveness and private investment in the energy sector. This reform is expected to increase oil and gas onshore drilling, including the development of shale resources through hydraulic fracturing (HF). Among the most relevant environmental challenges of HF are (1) the millions of gallons of water required per well, and (2) the large volumes of wastewater produced that require disposal. The main objective of this research is to estimate, given different annual drilling schedules, the potential increase of water volumes used in the oil region of the Burgos Basin (located in Northern Mexico) for HF activity. After proper treatment, these water volumes could be reused for HF to reduce the overall water withdrawal of this activity. To estimate water volumes, this analysis involves (1) forecasting water production decline curves of potential HF wells in the region analyzed using empirical observations and empirical decline models (e.g. exponential, harmonic, hyperbolic and hyperbolic to exponential), and (2) applying water production estimates to potential HF drilling schedules developed using historical records and future drilling estimates from multiple shale booms in the United States. Preliminary results, suggest that reusing the volumes of produced water from potential HF activity in this area could reduce the water withdrawals for this activity in this region. More research needs to be conducted to determine the quality of the produced water in this area and the treatment it will require to be reused in HF.
