  • ABSTRACT Managing water through the shale development process can be more complicated than is often anticipated. In the process of developing shales, water must be sourced, tracked, transported, blended, staged, used, produced, and recycled/disposed. Operators must plan for the pace of development, water requirements for drilling and fracturing must be defined (volume and quality), water losses (e.g., evaporation) must be accounted for, water conditioning and/or treatment must be designed and planned, transportation must be arranged (e.g., trucking, overland piping, etc.), storage must be arranged, permitting must be completed, and many other tasks. The complexity of the planning process has created a demand for a variety of modeling techniques to be used to more easily facilitate the planning process and to allow for change management when drilling and/or completion plans are modified. Determining the pace of water and storage demand alone can be complicated, but when considering the volume of water required in a very short timeframe for high volume hydraulic fracturing (HVHF), planning must be spot on. As part of three separate U.S. Department of Energy (DOE) research projects, ALL Consulting (along with many cooperators) have developed models that ease the water management planning process. This includes the Water Planning Tool (originally developed for Coal Bed Methane water planning), Water Blending and Scale Affinity Model, Water Treatment Catalog, along with others. This paper will present these and other tools while also discussing the challenge of lifecycle water management.

    In some plays, water blending is critical to meet both water sourcing demands and management of produced water

    Water blending can also be used to engineer water to reduce chemical additives in fracturing.

  • Managing Water Options

    Under active development scenarios, water management can be complex in any play.

    Planning must consider current and future development plans, locations, logistics, water sources, quality requirements, and more.

    Models become a beneficial means to effectively meet water management demands.

    Various models may be used for purposes such as: Planning water needs and disposal alternatives, Assessing treatment alternatives, Staging and blending water Etc.

  • Example Models Models are available from a wide variety of

    sources. Model examples developed by ALL as part of

    research with the U.S. DOEs NETL, GWPC, IOGCC and industry include: Water Assessment Tool (WAT) Water Catalog and Decision Tool Mixing and Scale Affinity Model

    Basic analytical models are also commonly used for planning and compliance.

  • WATER ANALYSIS TOOL

    Copyright (c), ALL Consulting, 2013 11 January 2013

  • Water Assessment Tool (WAT)

    Rapidly analyze various water management portfolio options in the design phase.

    Three components Water Balance Module Economic Analysis Module Water Mixing Model.

    Components can be utilized individually or in tandem.

    The WAT is an advanced planning tool that incorporates development needs with water requirements.

    12 Copyright (c), ALL Consulting, 2013 January 2013

  • WAT Modules Water Balance -

    Determine the viability of a conceptual water management portfolio. Allows the user to rapidly assess the ability of a potential water

    management portfolio to handle the estimated peak volume of produced water

    The water management portfolio can be adjusted through an iterative process until a satisfactory water management portfolio is determined

    Economical Analysis Estimate and compare costs, both capital and operational, associated

    with the different water management portfolios chosen in the water balance model.

    Compare estimated total cost of multiple potential water management portfolios for a project on a relative basis

    Water Mixing Estimate the change in water quality values of a receiving body of

    water when produced water discharge (whether it be raw water or treated water) into a surface water (such as a river) is anticipated.

    Calculates mix ratios of electrical conductivity (EC) and sodium adsorption ratio (SAR) after mixing of treated water with untreated raw water and average historical surface water data.

  • WATER MIXING & SCALE AFFINITY MODEL

    Copyright (c), ALL Consulting, 2013 14 January 2013

  • Scale Affinity and Mixing Model Predicts resultant chemical composition of

    mixed waters, allowing the user to see how waters are predicted to react when mixed.

    Addresses the mixing of multiple source waters, identifying the affinity for scale formation and the potential species of scale formed.

    Provides the ability to analyze multiple water sources and mixing ratios to identify the most favorable mix ratio of available waters to meet specified targets for quality parameters.

    Allows the development of an engineered water by specifying the desired limits for various constituents and then determining the optimum mix of up to three different waters

    Copyright (c), ALL Consulting, 2013 15 January 2013

  • The Water Blending Model Uses an established and verified aqueous

    geochemical model developed by the US Geological Survey (PHREEQC).

    Allows user to input multiple source water compositions and analyze the resultant chemical composition of water by mixing of different ratios of these fluids.

    The program predicts speciation formation through the calculation of saturation-indices, allowing the user to identify potential for the formation of the most common Carbonate and Sulfate scale-forming species.

    Model reacts mixed water solutions by allowing water chemistry to come to equilibrium on select species and then allows user to use that reacted water in subsequent modeling.

    Copyright (c), ALL Consulting, 2013 19 January 2013

  • Water Treatment Catalog Provides a description of the water

    treatment technologies applicable to shale gas development, profiles of the known vendors that are active in the project basins, and links to vendor sites.

    Provides a system that guides users to the treatment technologies that best fit the users water quality, water management and regulatory situation.

    Provides a tool to predict the detailed chemical reactions that will take place when the users produced water sources are mixed with their fresh water and provides relevant scale indices.

    Provides federal, state, or river basin commission agencies that regulate shale gas produced water management as well as links to both the regulations and to the agency web-sites.

    Technology Highlights

    As part of the Ozonix process, super-saturated ozonated water is flash mixed with influent and dual-frequency ultrasonic transducers initiate the dissolved gas flotation of oils and suspended solids and the conversion of ozone to hydroxyl radicals

    Nano-cavitation bubbles imploding provide the liquid-gas interface that is instantaneously heated to approximately 900oF, which in turn oxidizes all known organic compounds.

    Ultrasonic cavitation cleaves larger particles into smaller particles for faster removal by flotation.

    The last step of the Ozonix process, if required, separates brine from fresh water by using RO technology

  • Technology Highlights

    Combination of pre-treatment, microfiltration, and RO are operated in series to treat produced water compositions and generate clean water stream that can then be discharged or reused for fracing

    Depending on the quality of the feed water, the process implements various pretreatment processes to remove dispersed oil, suspended solids, or dissolved hydrocarbons

    Pretreated water is then further purified with polymeric microfiltration and RO

  • CLOSING THOUGHTS

    Copyright (c), ALL Consulting, 2013 26 January 2013

  • Summary Planning for the entire water management

    lifecycle is essential (including compliance). Water planning in any play is complicated when

    development includes high drilling and completion activity.

    Water management considerations can be very complex with one decision affecting multiple other decisions.

    Use of models provides comprehensive, consistent consideration of options.

    Modeling also enables strategic innovative planning and incorporation of sustainable solutions.
