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.

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

• Oil gravity from 14-41 API.
• 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)

The OOR ‘Sweet Spot’

20

Step 1 - Screening

• Well Understood Geology (mapping).
• Good Water Injection History, Indicated Response.
• Current Well Completion Diagrams.
• Oil and Water Production Records.
• Chemical Treatment History.
• Full H2S History.

Ideal Data Profile

21

Step 2 - Laboratory Analysis

• Titan Sampling Kit at Well Location.
• 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.

Verifying Reservoir Biology

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.
• Well Restarted Sampling:
• daily over the first week
• One per week for a month
• Once per month following
• An ISMRA lab and production report is provide with

recommendations for next steps.

Proving Microbial Response

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.
• Samples are taken from Offset Producers Weekly, until

Production Increases Kick In – Thereafter every second Day for Two Weeks.

Initiating the Production Increase

24

Step 5 - Full Field Application

• Occurs when targeted water flood shows a clear positive
• il 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.
