For several years now, regulatory agencies including the US Environmental Protection Agency (EPA) and energy associations like the American Petroleum Institute (API) have provided recommendations, regulations and guidelines to improve water management in oil and gas exploration. Energy companies from Apache to Devon and Seneca to Williams have deployed new best-practice methods to reduce fresh water usage in drilling and hydraulic fracturing. To fully appreciate the total life-cycle costs of fluids used for hydraulic fracturing, one needs to examine the total costs of fluid acquisition, management, and disposal. Typically, these costs are divided within various groups within an operator (i.e., completions and production) with emphasis on acquisition during the completions process. This paper examines the total hydraulic fracturing fluid life cycle costs and examines when fracturing fluids energized with carbon dioxide (CO2) or nitrogen (N2) to reduce the volumes of water required can be more economical for hydraulic fracturing. In addition, when the added benefit of energized fluids increasing production performance is included, the unit costs of production can be lower even when total life cycle costs comparisons are at par or higher. To approach this analysis, we will look at “A Day in the Life of a Barrel of Water” used for hydraulic fracturing.
