1 Optimal Tertiary Recovery Strategies for Mature Wells More Oil, Naturally Daan Veeningen August 26 th, 2015

2 Offsetting Price: More Oil Discovering New Fields Exploiting Tight Fields Extracting Mature Fields

3 Adding Biology, in a Nutshell 100 ppm nutrients to existing sandstone water flood 60 % reduction in decline curve 30-40% higher oil production rate 20 % more recovery on OOIP (Statoil), 9-12% in US Land 10 ppm or less oil in water, TOC, TDS 1 producer(s) in continuity with a downdip injector(s) 5-8 years extension of economic field life (US land) 7 years of delay for water break through (North Sea) 10-15$ cost per incremental barrel of oil produced 80 % improvement in cash flow 230 DegF BHT for field that Glori owns and operates 2

4 Talking Points Overview of technology Results in the Field Considerations for Implementation Conclusions and Recommendations 3

5 Fundamental Water cut Why is this Relevant? Niels Bohr Louis Pasteur 100% Extracting Residual Oil 90% Water cut versus liquids produced Standard FUNDAMENTAL 80% Water Drive 70% Activate subsurface biolife with nutrients 60% 50% Act as a surfactant reducing interfacial tension 40% APPLICABLE 30% 20% Mobilize residual oil flow in water flood AERO / drive 10% reservoirs 0% Produce 0 updip 20 from 40 injector 60 wells Cumulative liquid production (% of total) Not fundamental, not applicable Thomas Edison Applicable 4

6 Fundamental Why is this Relevant? Niels Bohr Louis Pasteur Not fundamental, not applicable Chemical Miscible/immiscible gas Polymer Steam Thomas Edison Applicable 5

7 What is the Action in the Reservoir? SPE paper ~125% Uplift ~65% Uplift ~70% Uplift BASELINE Proposed Reversible Rapid response Local, near wellbore Proposed Permanently altered Transit time of fluid front Pervasive, throughout

8 Barrels of Oil per Day Log Scale What does it mean for You? More Higher Extend Better Oil Recovery Rate Life Cut Higher Production Rate More Recovery Better decline Adding reserves Extend Life Better Oil Cut Original Oil in Place A B C Economic Limit Extending Economic Life Injection Time

12 Alberta Higher Rate, More Recovery JPT Article March 2015 Incremental recovery = 68 mbo and rising Life extension of the field = 5-8 years while increasing reserves >4x Production still increasing at 2 years, Lifting costs continue to drop

17 Conclusions, More Oil from Mature Fields Unique, Applicable Process to Extract Residual Oil Adding biology creates bio-diversion improving sweep and conformance Production rate increase is rapid and response reversible Field results: More Oil Higher Rate, 2-4 month response, > 1,000ft % higher rate Improve oil cut, reduce lifting cost More Recovery Up to 50% reduction in decline rates 10-20% more recovery of OOIP 16

18 Recovery (%) Recommendations for More Oil, Lower Cost Extraction (Time) Adding Biology: Wide applicable: From initial water-drives to mature waterflood fields Small footprint, fundamental impact: Short time to uplift, existing infrastructure Low CAPEX: Promotes earlier deployment Better OPEX: Delayed water breakthrough, reduced water handling, extend mature fields economically 17
