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.

This is the third article of a series on water management for hydraulic fracturing in unconventional resources. This month, water treatment technologies are introduced, beginning with the removal of suspended solids by coagulation/flocculation and electrocoagulation for recycling flowback fluids. -
Concerns have been expressed and published about the amount of water used in Canada’s oil-sands industry.
-
Technology is evolving to meet the challenges to automate water separation and purification in deepwater for environmentally safe discharge at the seabed. To solve these problems the best available solutions must be selected and the technology gaps must be identified and closed.
-
In this second article of a series covering water management in hydraulic fracturing (HF) in unconventional resources, the properties and characteristics of the flowback fluids are discussed, together with the general categories of technologies that are best suited to treat them.
-
Enhanced oil recovery processes, particularly offshore, create challenges for produced water treatment. This option reviews technology options and current applications.
-
This is the first of several articles on the subject of water management for unconventional hydraulic fracturing. This article outlines the critical issues and outlines development of a strategy for treatment of flowback fluids.
-
The number of offshore facilities employing waterflooding with desalination continues to grow. Currently, more than 50 sulfate removal units are in operation offshore with a total capacity of approximately 8 million BWPD.
-
Produced water has typically been viewed as a waste product to be disposed. A recent webinar explored ways that this waste can be turned into value through treatment and reuse. Available options vary with the quality of the produced water.
-
Changing the salinity of injection water could make the difference in getting more out of existing wells.
-
Using low-sal water for flood can add 30% to the amount of oil that can be recovered from a reservoir. What is the theory behind it?
