The United Nations Brundtland Commission defined sustainability as “meeting the needs of the present without compromising the ability of future generations to meet their own needs.” In the context of this definition, sustainable water management should encompass current management of water resources as well as its potential effect on the future. Sustainable water management in oil and gas is a journey that will need approaches from many perspectives.
The highlighted papers illustrate the different perspectives and accompanying complexities that can advance progression toward more-sustainable water management. The approaches are multifaceted in that they consider technological, environmental, economic, and social needs and responsibility. The papers include issues and challenges in reuse/recycling of produced water, new guidelines to standardize application of risk-based assessments to assess potential environmental impact from produced-water discharge, and a novel certification process for responsible water use.
A common thread found in these papers is the understanding driving criteria for current water practices, and measurement of these criteria will enable continual improvement. An example of this is the assessment of the water footprint for production activity in the Peruvian Amazon by Repsol in their journey toward their Blue certification. The assessment of the water footprint provided a benchmark for improvement, which, in turn, highlighted parameters to measure and key areas for mitigation.
