The Opportunity and Threat Posed by US Shale Water
The well count and completion intensity of US tight oil and gas operations have grown in recent years, and rising pressure from environmental regulations means that produced water management has become a key focus for operators.
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.
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.
Operators See Range of Options for Treating Flowback Water
A growing number of alternatives for treating flowback water enable operators to meet the requirements for discharge or reuse of the water in the fracturing fluid, a scientist said recently.
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.
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.
Water Management for Hydraulic Fracturing in Unconventional Resources—Part 1
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.
Handling Produced Water From Hydraulic Fracturing
The recycling of produced water and fracture flowback water for reuse in hydraulic fracturing is on the rise in the development of unconventional resource plays.
