water treatment

This first of a two-part series provides guidelines for designing and operating advanced produced-water systems on offshore platforms, covering fluid characterization, chemical treatment, equipment, process configuration, operations, and effluent quality.

The Permian’s produced-water challenge presents an opportunity for innovation to pave the way toward a more sustainable future for the industry.

Nature-based solutions, such as constructed wetlands, have gained increasing interest over the past decade as a sustainable option for wastewater treatment in the domestic, industrial, and oil and gas sectors, with a growing number of examples now existing throughout the UAE, Oman, and other oil-producing regions.

This paper presents a summary of the results of a study of the potential for repurposing legacy oil and gas facilities in the Gulf of Mexico for uses in a blue economy.

This paper is the second of a two-part series. It covers facilities problems caused by iron, injectivity problems caused by iron, and the mitigation of colloidal iron-related problems.

A review of the properties of iron compounds and their impact in shale produced water treatment with an emphasis on their colloidal forms. A wide range of problems is associated with these compounds in produced water including emulsion stabilization, oil-coated solids, pad formation in separators, pipeline solids, and plugging of water disposal formations.

Frac water disinfection experts become De Nora service arm in the unconventional oil and gas market.

By understanding the factors involved in oil droplet coalescence, the Savvy Separator engineer can assess the operational/chemical factors in the treatment system that are affecting droplet growth and make adjustments to enhance coalescence rates. 

Nanoparticle catalysts could play a major role in cleaning contaminated water for upstream oil and gas and other industries, says Michael Wong, chair of Rice University’s chemical and biomolecular engineering department.

Companies are deploying a variety of technologies to reduce the water needs of hydraulic fracturing. Where are these new facilities with these new technologies, and how will they help operators solve the problem of finding water to use?
