Assessing the water footprint of drilling operations: A case study of well drilling in Texas

The water footprint of drilling operations is a critical environmental consideration in resource extraction, particularly in water-scarce regions such as Texas. This paper evaluates the water consumption associated with drilling different types of wells in Texas, with a focus on the water used in drilling, completion, and hydraulic fracturing processes. By analyzing various well types, including vertical, horizontal, and multi-stage hydraulic fractured wells, we aim to quantify the total water footprint required for each process. The study leverages data from recent drilling operations to estimate water usage and discuss the sustainability of such practices in the context of ongoing water scarcity issues in Texas. This paper highlights the need for better management of water resources in drilling operations and offers suggestions for reducing water consumption through technological innovations and operational efficiencies.
