WATER TREATING INSIGHTS
Addressing the Gaps in Subsea Produced Water Treatment
Operators are looking for ways to better handle water coming from subsea wells, which is typically treated at topside facilities. Subsea separation systems are not equipped to discharge water back into the reservoir, so how do companies close the gaps?
Permian: Treating Produced Water for Discharge Reduces Injection
Operators in the Permian Basin are looking for new ways to handle the rising volumes of produced water coming out of the region without using saltwater disposal wells. One solution, treatment for discharge, could provide an efficient alternative.
Bacteria: The Real Water Issue of Hydraulic Fracturing
Though a best practice for sustainable hydraulic fracturing operations, using nonpotable water creates an environment in which microorganisms thrive. If left unchecked, bacteria can affect the environment and the economic viability of the hydraulic fracturing operation.
Operators Explore Agricultural Options for Reuse of Flowback and Produced Water
Market dynamics and costs drive the search for solutions. In California, where water is needed, producers are finding potential for reuse of waste water.
Unconventional Resources: New Facilities Find Solutions to Limited Water Sources
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?
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.
Unconventional Oil and Gas Production Drives Trends in Water Management and Treatment
This article explores the outlook for the global market and gives insight into technology trends and the regions that hold the biggest opportunities for water treatment.
Chemical Pretreatment of Guar Gum-Based Hydraulic Fracturing Solutions and Produced Water
Hydraulic fracturing solutions use a gelling agent known as guar gum to transport proppant. Flowback water can have guar gum concentrations has high as 1% by volume creating treatment challenges prior to reuse or disposal.
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.
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.
Water Management for Hydraulic Fracturing in Unconventional Resources—Part 4
This is the fourth article of a series covering water management in hydraulic fracturing (HF) in unconventional resources. This article discusses the use of mechanical vapor compression (MVC) as a desalination technology.
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.
Micro- and Ultrafiltration Technologies Offer New Options for Offshore Waterflooding
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.
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?
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.
Challenges of Water Treating for Chemical Enhanced Oil Recovery
Higher oil prices has created increased interest in chemical enhanced oil recovery (CEOR) using polymers, surfactants, and alkalis. This technology poses some special challenges, especially around water treatment.
Global Workshop Series Addresses Water Handling Issues
Water handling is becoming increasingly important as a technical and economic tool for improved oil recovery and enhanced oil recovery (EOR) projects. A global series of workshops to address these issues has been planned.
A Historical Perspective on Produced Water Treatment
The author reviews advances in produced water treatment, particularly offshore, since the 1960s. Regulations on discharge quality have been a major driver in the improvement of treatment technology.
Technologies, Trends, and Developments
For several months, a number of us involved with water treating have been thinking about how we would like to contribute to Oil and Gas Facilities. We had in mind a regular feature with an emphasis on water treating technology.
