SESSIONS

Spanning the Spectrum with Ion Exchange
Date: Monday, November 16
Time: 8:00-11:00AM
Ion exchange resins (IXR's) are a versatile group of products with known performance characteristics in "thin waters". However, efficiency and performance changes when used in a high TDS environment. This session spans the spectrum where IXR's are used with one author revisiting continuous ion exchange (CIX) technology patented in the1950's including a novel approach to turn its waste stream into a revenue stream. Another author uses 21st century simulation technology to predict how resins will respond in a high TDS environment while the final paper uses empirical data to support conclusions on resin selection.

Time: 8:00-11:00AM
Produced water is among the most challenging process waters to treat. High levels of precipitable salts, silica, and organic compounds are dissolved in petroleum bearing formations and flow to the surface along with the oil that is being produced. Technologies have been practiced successfully and many more are being studied and developed to meet this growing need for recycle, reuse and discharge of produced water. This session focuses on produced waters from the SAGD facilities of western Canada. The session will take you through technologies used to successfully treat steam EOR produced water, review the progress of a ZLD system, and explore new innovations to treat high TDS brines associated with produced water. If you want to truly learn about produced water treatment or have experience in the SAGD market, this is the session for you!

Steam Corrosion and Control
Date: Monday, November 16
Time: 8:00-11:00AM
Steam corrodes the pipes and tubes that it passes through. At low corrosion rates this is actually a good thing as the corrosion creates and maintains a passive layer that lowers corrosion rates to almost zero. However, if corrosion rates are too high the passive layer is removed before it can form and the pipe can fail quickly. This session’s papers address some of the conditions that cause high corrosion rates in the steam system.
The first paper is a review of lessons learned in HRSG boiler tube failures. The second paper discusses the chemistry of passivation and film formation. The third paper discusses Flow Accelerated Corrosion – the causes and effects.

Membranes Tackle New Application Challenges
Date: Monday November 16
Time: 1:00-5:00PM
Membranes have been used for decades now, but have traditionally treated relatively “clean,” fresh water, make-up sources. As supplies of clean water dwindle and make-up quality declines, membranes are being tasked with treating more challenging sources of water. To tackle these challenges, advancements in membrane technology are being called upon to remove contaminants to a higher degree under highly fouling conditions. This session includes papers which discuss the treatment of make-up sources such as refinery wastewater and grey water, new membrane chemistries to improve rejection of contaminants, module design to minimize biofouling, and the improvement of membrane system efficiencies. This program will demonstrate how continued development in membrane technology will allow for membranes to meet the future challenges of declining water quality and availability.

Success in the Treatment, Reuse & Disposal of Frac Water while managing Risks
Date: Tuesday, November 17
Time: 8:00AM-Noon
There are currently several accepted alternatives for handling hydraulic fracturing flowback and produced water (aka brine). This session will discuss and explore some of these including evaporation and reuse. Results from a brine treatment facility that uses a thermal evaporator to produce safe, clean distilled water and a concentrated salt byproduct will be presented. The difficulties of handling produced water with radioactive material (known as NORM) and options for reuse and disposal will be discussed. A case study from a recent collaboration between three oil and gas service providers and a large producer in the Delaware Basin (New Mexico) for environmentally responsible, economically advantageous reuse of produced water for hydraulic fracturing will be presented. Another case study will present the concerted effort to maximize the degree of reuse of produced water, reviewing the water and performance tests results. The flowback water was collected, treated, stored, prevented biogrowth and was 100% reused as hydraulic fracturing make up water. The evaluation of economics for this zero discharge recycling system shows operational cost savings based on the deferred cost of water acquisition and disposal. Industry experts conclude that such an optimized approach could lead to improved well completions and wells that are more productive.
