A Comparison of Methods for Boron Removal From Flowback and Produced Waters
While storage and logistics are critical elements of the viability of water reuse, if the water chemistry is not fit for gel fracturing formulations, it will not matter how much is stored in centrally located impoundments.
Mechanical Vapor Recompression for the Treatment of Shale-Gas Flowback Water
Used extensively by the food, chemical, and pharmaceutical industries, the mechanical-vapor-recompression (MVR) process is viewed as a reliable method for recovering demineralized water from concentrated brines. This paper reports on performance of an advanced MVR system in north-central Texas.
Optimizing Water Storage in Oilfield Water Treatment
With inconsistent inlet water quality being the rule rather than the exception, sizing and operational considerations of the treatment system components must vary accordingly to make the most economic sense.

In this study, a pilot plant with a capacity of 50 m3/d was used to conduct flotation, filtration, and adsorption trials for produced-water treatment at a crude-oil gathering facility.
Produced and Flowback Water Recycling and Reuse - Economics, Limitations, and Technology
The demands for the fresh water used in many hydraulic fracturing operations are placing pressure on water sources in some regions of the United States. Because of the high volumes of water needed for fracturing and competing demands availability of fresh water has decreased and costs have grown.
Water Management for Hydraulic Fracturing in Unconventional Resources - Part 5
This is the fifth article in a series covering water management in hydraulic fracturing in unconventional resources. The focus of this article is biological control. Additives to improve fracturing conditions can have negative effects on water treatment.
Use of the ALARP Principle for Evaluating Environmental Risks and Impacts of Produced-Water Discharged to Sea
As low as reasonably practicable (ALARP) is common for management of safety risks, but harder to apply to environmental risks. This paper explores the differences and proposes a modified method to support environmental risk analysis.
Water Management for Hydraulic Fracturing in Unconventional Resources - Part 3 Water Treatment Technologies: Coagulation/Flocculation and Electrocoagulation
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.
Treating and Releasing Produced Water at the Ultradeepwater Seabed
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.
Water Management for Hydraulic Fracturing in Unconventional Resources—Part 2 Properties and Characteristics of Flowback Fluids
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.
New Water-Treatment Technologies Tackle Offshore Produced-Water Challenges in EOR
Enhanced oil recovery processes, particularly offshore, create challenges for produced water treatment. This option reviews technology options and current applications.
Produced Water Management Offers Value to Companies
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.
The Lowdown on Low-Sal Water Technology
Changing the salinity of injection water could make the difference in getting more out of existing wells.
How Does Low-Sal Water Work?
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?
Chemical and Mechanical Problems in Produced Water Treating Systems
Ted Frankiewicz' Distinguished Lecture presentation on “Diagnosing and Resolving Chemical and Mechanical Problems in Produced Water Treating Systems” was the subject of a recent webinar.
New Options for Produced Water Treatment
A recent webinar discussed current technologies to enable reuse of produced water in gas and oil shale developments.
Sulfate Removal—The Adoption of a Water Treatment Technology by the Oil and Gas Industry
The oil and gas industry is sometimes slow to adopt new technologies and other times quick to deploy a new approach. The decision whether to try something new weighs the perceived risks and rewards.
Evaluation of Scale Inhibitors in Marcellus High-Iron Waters
The high level of dissolved iron commonly present in the Marcellus waters of Pennsylvania and West Virginia adversely affects the ability of scale inhibitor to inhibit calcium carbonate scale. This study tests two new products under a range of conditions.
