WATER TREATMENT AND MANAGEMENT
Preventing Emulsions by Mitigating Solids
Approaches to integrated investigative testing and root cause identification are discussed to prevent solid emulsions from stabilizing to impair flowlines and other field infrastructure.
Industry and Academia Continue Working on Big Ideas for Nanotechnology
A number of ongoing industry research projects are developing nanoparticles that work at the reservoir level and for fluid treatment. Though they may be a few years away from finalization, these efforts highlight nanotechnology’s increasingly sophisticated and growing application scope.
More Oil, More Water: How Produced Water Will Create Big Cost Problems for Shale Operators
If crude prices, rig counts, and tight oil production demonstrate a stronger upward trend in the months to come, US shale operators may find themselves with more produced water than they bargained for.
Considering the current downturn in crude prices, there is a renewed interest in recycling produced water for reuse in hydraulic fracturing in the development of unconventional resource plays.
Fit-for-Purpose Treatment of Produced Water for Hydraulic Fracturing in the Permian Basin
Sourcing water for large multifracture stimulations in west Texas is a well-known constraint on oil and gas activities in the area. A 6-month pilot operation demonstrated that produced-water reuse is technically feasible and can be a cost-effective solution.
Solving Produced-Water Challenges With a Novel Guar-Based System
This paper summarizes the benefits of using a bipolymer crosslinking system in environments where water quality cannot be guaranteed. It also demonstrates the yielded cost savings per well that are achievable when reusing 100% produced or flowback water for hydraulic fracturing.
Produced-Water Reinjection—Case Study From Onshore Abu Dhabi
Water production normally increases as fields mature, and two main ways exist to deal with the produced water. One is to dispose of the produced water into dedicated disposal wells. The other is to reinject the produced water for pressure maintenance or sweep efficiency.
UPDATE - Oklahoma Earthquake: 5.0-M Quake Damages Buildings in Oil Hub of Cushing
Earthquake in Cushing, OK -- home to the largest oil storage facility in the world -- leads to further regulatory action on disposal wells in the area.
In Search of Cheap, Fast Ways To Detect Water Troubles
Treating produced water to control bacteria is like weeding a garden. It addresses the problem that is not going away.
New Field Testing Device for Water Competes With Laboratory Methods
Analyzing the properties of produced water is a difficult process because of the extreme levels of suspended and dissolved particulates contained in it, and a chemistry profile that is in constant flux.
TOC Analysis Gains Acceptance as a Standard for Organics Testing
The presence of excessive levels of organic components in produced water can lead to costly problems for operators ranging from clogged membranes in treatment facilities to environmental issues and compliance with government permits.
Chemical Analysis of Flowback Water and Downhole Gas-Shale Samples
In this study, samples of flowback water and downhole shales are analyzed to investigate the mechanisms controlling the chemistry of flowback water.
Ohio Study Tries To Pin a Number to Earthquake Risk
Research and development firm Battelle is working on a new induced-seismicity study that aims to help wastewater disposal well operators in Ohio stay on the good side of state regulators.
New Nanodevice Designed To Simplify Produced Water Treatment
A new techhnology aimed at treating produced water at the wellsite to near-drinking-water quality.
Small Bubbles, Big Rewards for Separation Technology
Tiny bubbles, called nanobubbles, are the focal point of a new innovation aimed at transforming produced water from a costly byproduct into a valuable asset.
Seismic Shifts in Oklahoma Lead to Stricter Regulations
Industry regulators in Oklahoma have rolled out broad new restrictions on more than 600 disposal wells as part of the largest action of its kind taken in response to earthquakes.
Treating Produced Water With Understanding
Produced water has become the largest byproduct in the oil and gas industry. Treatment and disposal or reuse of this byproduct requires a good understanding of conditions and options to devise the optimal strategy.
Statistics Point to Water Injection as Cause of Earthquakes, But Understanding Why Remains a Geological Puzzle
A surge in earthquakes tightly clustered in southern Kansas that followed the large increase in produced water injections prompted the state to cut the daily limits on disposal wells in that area to see if that will help solve the problem.
First Reuse of 100% Produced Water in Hybrid Treatments With Gelling Agents
This paper reports the completion of a two-lateral well in the Williston basin where produced water (PW), filtered but otherwise untreated, was used throughout the slickwater and crosslinked components of approximately 60 hydraulic-fracturing stages.
Permian Basin Fracturing Systems Using Produced Water
This paper details the experience of using new stabilized crosslinked-fracturing-fluid systems in the Permian Basin using borated produced water.
Water Management: Lessons Learned and Considerations for a Shale Play in Argentina
This paper discusses aspects of water logistics necessary during the well-completion phase, fracture-treatment designs applied in Vaca Muerta, and laboratory studies performed on flowback and produced water to help evaluate the potential for water reuse.
In the interest of conservation and sustainability, it is highly desirable to maximize any opportunity to reuse the produced water for subsequent fracturing treatments.
An Environmental Perspective on Risk Management and Water
There is no denying that the oil and gas industry, as well as the agencies that regulate its activities, have significantly improved many aspects of environmental performance. Despite this progress, there is always more to be done to identify and manage risks associated with oil and gas development.
SPE Effluent Discharge Management Workshop Addresses Standards and Regulations
The SPE Trinidad and Tobago Section recently hosted an Applied Technology Workshop (ATW) on oil and gas effluent discharge management that brought together those responsible for generating effluent discharges, regulators, and those creating treatment technologies
