Oil Water Interface 7
Oil Water Interface Oil Micro-Droplet Formation is the Release Mechanism Pore Throat Flow 30 cm/day Oil Interactive Microbes 24 Hours Between Photomicrographs 8
Improved Recovery Factor Pore Scale Displacement – is improved Interfacial Tension – between oil and water decrease as the oil interactive resident • microbes be come hydrophobic and they are pushed by the water to the oil/water interface. Improved Oil Mobility – Smaller micro droplets can more easily move through the pore • matrix and be recovered Wettability – Oil droplets are more easily released from the reservoir surfaces • Sweep Efficiency – is improved Micro Emulsion Formation - can lead to improved diversion of water which in turn can lead • to improve displacement of oil from previously upswept regions. Improved Recovery and Water Cut Decrease 9

Organic Oil Recovery (OOR) 3. The Process 18
OOR – Five Step Process 1. Field Screening of Reservoir Characteristics. 2. Laboratory Analysis – DNA Analysis. 3. In-Situ Microbial Response Analysis (ISMRA). 4. Targeted Water Flood Implementation. 5. Full Field Application. 19
Step 1 - Screening The OOR • Oil gravity from 14-41 API. ‘Sweet Spot’ • Water pH between 6-8. • Current Reservoir Temperature Less than 95 C. • Formation Water Salinity of Less than 140,000 ppm TDS. • Field Pressure History, more than 25% of Original. • Reservoir Porosity of more than 20% of formation volume. (higher the better in general) • Reservoir Permeability of greater than 7.5 millidarcies. (higher the better in general) 20
Step 1 - Screening • Well Understood Geology (mapping). • Good Water Injection History, Indicated Response. • Current Well Completion Diagrams. • Oil and Water Production Records. Ideal • Chemical Treatment History. Data • Full H2S History. Profile 21
Step 2 - Laboratory Analysis Verifying Reservoir • Titan Sampling Kit at Well Location. Biology • Samples Collected by Customer Personnel. • Sample Kits Designed to Maintain & Log Transit Temperature. • Samples Currently Shipped to Lab in California. (UK 2018) • Processed in the Lab to Map Microbial Life Cycle & DNA. • Lab Reports are Typically Issued within 4 Weeks. 22
Step 3 – ISMRA • The nutrient package is blended. • Nutrients are delivered in a partially filled 1000 liter tote. • Blended with 100 barrels of clean production water. • Displaced with 150% of the tubing or casing volume. • Production well is shut in for 7 days. Proving • Well Restarted Sampling: Microbial • daily over the first week Response • One per week for a month • Once per month following • An ISMRA lab and production report is provide with recommendations for next steps. 23
Step 4 - Targeted Water Flood • ISMRA Wells Selected with Offset Producer. • Larger Volumes of Nutrients Tailored to the Field. • Injector Shut in for 2 Days Gradually Retuned to Full Rate. • Three Treatments, 4 to 6 Weeks Apart. • Sampling at Offset producers to Establish Baseline. Initiating the Production Increase • Samples are taken from Offset Producers Weekly, until Production Increases Kick In – Thereafter every second Day for Two Weeks. 24
Step 5 - Full Field Application • Occurs when targeted water flood shows a clear positive oil production response. • Bi-weekly well samples are taken to monitor field production. • Further injection treatment will typically occur every 3 to 4 months based on microbial response. Monitoring & Maintaining the Production Increase 25
