Water management
This paper presents an approach to the identification, selection, and implementation of initiatives for sustainable water management, withdrawal reduction, and water valorization.
Disposal wells remain the lowest-cost solution for produced water, but concerns over seismicity and long-term sustainability are accelerating interest in alternatives.
This article addresses the challenges of managing water-soluble organics (WSOs) in offshore produced water. It provides a brief discussion of the chemistry, along with strategies and technologies that can be used to manage WSO levels in produced water, thus facilitating compliance with regulatory overboard water-quality guidelines.

In the current economic environment, efficient water management practices will become even more essential for companies looking to run successful hydraulic fracturing operations. -
The SPE Trinidad and Tobago Section recently hosted an Applied Technology Workshop (ATW) on oil and gas effluent discharge management that brought together those responsible for generating effluent discharges, regulators, and those creating treatment technologies

There is no denying that the oil and gas industry, as well as the agencies that regulate its activities, have significantly improved many aspects of environmental performance. Despite this progress, there is always more to be done to identify and manage risks associated with oil and gas development.
-
Produced water from chemical floods can cause problems for separation and water treatment equipment due to the polymers and surfactants used. Challenges are greater offshore where space limitations can affect treatment options.
-
Operators are increasingly sampling local groundwater prior to drilling as a risk management approach to deal with public concerns about hydraulic fracturing and other activities.
-
Though a best practice for sustainable hydraulic fracturing operations, using nonpotable water creates an environment in which microorganisms thrive. If left unchecked, bacteria can affect the environment and the economic viability of the hydraulic fracturing operation.
-
Water treatment systems in the North Sea differ from those in the deepwater Gulf of Mexico (GOM). This paper provides a detailed understanding of these differences and provides insight into the design of water-treatment systems in general.
-
Many oil and gas companies are pursuing fracture-flowback-water and produced-water recycling for subsequent drilling and fracturing operations. Removal of metals is important to success of these processes.
-
Southwestern Energy plans to be freshwater neutral in its hydraulic fracturing operations by next year, and the company is well on its way to achieving that goal, said the leader of the group responsible for bringing it to fruition.
-
Market dynamics and costs drive the search for solutions. In California, where water is needed, producers are finding potential for reuse of waste water.
