cash for drilling by outsourcing the disposal and treatment of oilfield produced and flowback water (“waste water”) Water quality is measured by amount of TDS (Total Dissolved Solids) which can include salts, boron, iron, calcium, strontium, magnesium, and barium (higher TDS equals harder to treat or dirtier water) The water quality and the geology vary by region / area and dictate the feasibility, cost of disposal and treatment systems Distance to disposal and treatment facilities, as well as the ability to handle large volumes of water, are key concerns for E&P companies Produced water from the well that occurs over the life of the well, and water recovered from hydraulic fracturing activities (flowback water) requires different levels of water treatment Waste water disposal and treatment provides fee-based revenue, with additional revenue generated from hydro-carbon recovery and recycled water sales 16 Water Treatment and Processing Operational Model Treatment and Disposal – Company-owned disposal facilities provide producers affordable well-disposal of wastewater generated from oil and natural gas production and drilling activities – Water treatment process separates solids and hydrocarbons from water prior to disposal – 24 x 7 operations, truck bay loading/unloading – Certain facilities are pipeline connected, providing stronger customer relationship with the producers – Proprietary well maintenance programs enhance injection-rates and service lives of the wells Recycle Operations – Provides higher quality of water treatment services where the clean water can be re-used by producers for fracking, well drilling, and completion projects – Offers producers an alternative to fresh water that minimizes the impact on aquifers, particularly in arid regions of the U.S. – Recycled ~33 million barrels (1.4 billion gallons) of water since 2008 Discharge Water – Multi-patented 14-step water treatment process – Cleans water to a better than drinking water quality – Returned over five million barrels (210 million gallons) back to New Fork River, Wyoming, a tributary of the Colorado River – Continued R&D investments to employ latest technologies in various basins 17 Water Solutions Overview Segment Operations Provides services for the treatment, processing, and disposal of wastewater generated from oil and natural gas production Generates fee-based revenue from the disposal of wastewater, the sale of recycled wastewater, and recovered hydrocarbons Multiple treatment, disposal, and recycling facilities located across the United States Long-term, deliver-or-pay contracts and acreage dedication contracts reduce cash flow volatility Provides high technology solution where necessary.
