WATER-BASED ENHANCED OIL RECOVERY(EOR)

WATER-BASED ENHANCED OIL RECOVERY(EOR) Global Water-Based EOR Potential is Estimated at 750 Billion Barrels - Shell 1 2 REDEFINING WATER TREATMENT FOR THE OIL & GAS INDUSTRY H 2 Ocean Spectrum TM technology allows operators to optimize oil recovery from maturing reservoirs by customizing water qualities on demand throughout reservoir life. This technology is the first of its kind to facilitate the shift between techniques such as Sulphate Removal to EOR seamlessly without changing process systems. ENHANCING OIL PRODUCTION Water-based EOR improves oil recovery over the life of a field. OIL PRODUCTION RATE EOR Operation Threshold BASE CASE Operation Threshold Production Plateau Production Decline Curve - BASE CASE Production Decline Curve w/eor Increased Oil Recovered w/eor BASE CASE Production Shutdown TIME FIELD LIFE Increase Field Life w/eor EOR Production Shutdown 3 OVERCOMING KEY CHALLENGES As primary recovery techniques reach their full potential, secondary and tertiary technologies are being implemented to extend oil field life. ADDRESSING THE INCREASING COST of exploration MATURING RESERVOIRS extending life where production has peaked MEETING MORE STRINGENT ENVIRONMENTAL STANDARDS DELIVERING CONSISTENT QUALITY of reservoir water chemistry OVERCOMING FOOTPRINT LIMITATIONS AVOIDING THE HIGH COST of decommissioning

We are excited with all the piloting results and the range and flexibility of the H 2 Ocean Spectrum TM technology. This technology allows us to manage the changing challenges of a reservoir s water chemistry and closely control hardness and salinity in the treated water to match any reservoir geochemistry. - Amanda Brock, CEO of Water Standard 4 FLEXIBLE & INNOVATIVE SOLUTION Water Standard s proprietary H 2Ocean Spectrum TM technology is a turnkey solution that can adjust output water quality on demand for: 65 PPM 60 PPM 70 PPM 55 PPM 75 PPM 5 PPM 10 PPM SULPHATE 15 PPM 35 PPM 20 PPM 30 PPM 25 PPM 90,000 PPM 80,000 PPM 100,000 PPM 70,000 PPM 1,000 PPM 10,000 PPM SALINITY 20,000 PPM 40,000 PPM 30,000 PPM 100 PPM 70 PPM 5 PPM 65 PPM 10 PPM 15 PPM 20 PPM HARDNESS Ca 25 PPM 45 PPM 30 PPM 40 PPM 35 PPM 70 PPM 65 PPM 100 PPM 60 PPM 5 PPM 10 PPM 15 PPM 20 PPM HARDNESS Mg 40 PPM 25 PPM 30 PPM 35 PPM OUTPUT 50 PPM 45 PPM 40 PPM 60,000 PPM 50,000 PPM 60 PPM 55 PPM 50 PPM 55 PPM 50 PPM 45 PPM CUSTOMIZABLE throughout the life of a reservoir FLEXIBLE AND ROBUST engineering design ADDRESSES THE RANGE OF WATERFLOOD TECHNIQUES like chemical enhanced oil recovery (CEOR), low salinity injection, or sulphate removal packages (SRP)
