produced water

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.

This paper describes a solution for downhole salt precipitation involving the installation of velocity strings.

The retrofit merged enhanced gravity separation with induced gas flotation within the same vessel. Detailed insights into the design, operation, and performance of hybrid flotation systems are provided, offering valuable guidance for similar initiatives in the petroleum industry.

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

Researchers at Texas A&M University have developed a method of refining "liquid gold" for valuable critical minerals using what many consider traditional waste products: produced water and carbon dioxide.

This paper describes a method to manage high-salinity produced water in an environmentally sustainable way by extracting potable water and reducing discharge water volume by at least 50%.

This paper presents the evaluation results of a water-shutoff agent based on an emulsion-type chemical material with nanoparticles.

The authors of this paper discuss the use of dissolved polystyrene waste for the preparation of nanomembranes for separation of hydrocarbon pollutants from wastewater streams.

This paper outlines issues to be resolved during facility design and provides guidelines, calculations, and examples for sand-handling steps to be implemented after separation.

Permian Basin oil wells produce a lot of water. Much of it is injected into disposal zones above and below the basin’s primary oil- and gas-producing zone. When water is injected into these disposal zones, the pressure increases, mainly because no fluid is concurrently removed. Is this increase in pressure a concern? The data would suggest yes.
