AGENDA• Introduce the idea• Portable Frac Water kit

• Explain the importance• Water usage• Who will benefit

• The portable frac kit• How it works• Quality Control• Bacteria• Chemistry

• Conclusion2

AN INNOVATIVE FRAC WATER TESTING KIT

• Onsite testing of water to be used for Hydraulic Fracturing mixtures

• Will be used as a way to screen good water from bad water

• It’s cheap and quick

• Will be a catalyst to new innovations in oil field water usage 3

CURRENT WATER PROBLEMS IN TEXAS• A typical shale well uses 5M gallons of

water for hydraulic fracturing• 7 Billion bbls Produced water per

year in the Eagle Ford formation (Adham 2014, USDOE)

• 40% of water used for fracing comes back up to the surface

• Handling water is expensive Fresh water costs:

$0.88-6.05/bbl Disposal costs: $1.13-$10.75/bbl

Water management accounts for up to 10% of well costs (IHS)

Frac Pond (Energy Corp. of America)

• Important chemistries in produced water prevent us from using it directly due to compatibility issues (Blauch 2010)

WATER IN HYDRAULIC FRACTURING FLUIDS

• Slick Water• Sand + Water + Acid• Pumped at extremely high rates (60-100 BPM) to achieve fracture

• Cross Linker Gel• Sand + Water + Acid + Guar Gel• Uses high viscosity and density to achieve fractures

5

WHAT IS PRESENTLY DONE

Currently produced water is: • Re-injected into reservoir to maintain pressure, 56% • Pumped into disposal wells, 39%• A small percentage is cleaned and recycled, about, 3%

Cleaned using: • Coagulation, hydrocyclones, coalescers, flotation, and micro, ultra,

nano, and reverse osmosis filtration systems

WHO CAN BENEFIT FROM THE KIT?

• Service companies (Halliburton, Schlumberger, NOV)• These companies are responsible for the quality of hydraulic

fracturing job• Can use the kit to help them cut costs and deliver a better

product• Lower oil prices means lower margins, and every bit counts

• Operators• Lower water handling costs• Can make locals happy because of less water usage• Wastewater management is the primary driver of costs

WATER REUSE IN COMPLETION ACTIVITIES

• Flow Back or Produced Water contains high concentrations of a variety of ions

• Kit can determine water compatibility for operations

• Pre and post cleaning chemical levels

SCALING TENDENCIES

1. Scaling: Oil and gas recovery reduction due to the formation of typical scales such as sulfate salts of calcium, strontium, and barium.

Example Scaling Problem:

Assumptions:Flowback water has 20 mg/L of Ba2+

Groundwater has 200 mg/L of SO4

LETS REVIEW: RAPID CHEMISTRY KIT FOR COMPATIBILITY TESTING

The main purpose of our kit is to: • Only takes 1 hour to complete all the tests• Identify ‘good’ and ‘bad’ water on site• Less than 5% error compared to certified lab• Provide a reasonable estimate of contamination levels• Less than $20 to complete all tests

As a result of using our kit, you should see a reduction in: • Less down time on rig site• Fresh water needed for completion activities • Expenses related to water purchase • Tensions between local communities and production
