1. First Order Exploration A technological basis for the direct detection of oil and gas fields using Direct Hydrocarbon Indicators (DHIs) Investigative data sets are ordered according to their proximity to the object of the search. The lowest order data sets are most predictive. Confidential 1
2. Oil and Gas Exploration Technology Overview Confidential 2 First Order Exploration, LLC
3. Oil and Gas Exploration – a direct approach The General Question: Before drilling, -can oil and gas be detected and explored for directly? The First Order Hypothesis: Direct Hydrocarbon Indicators (DHIs) can find Oil and Gas more directly and more efficiently than industry standard technologies. The Industry Hypothesis: Gas can be found directly through AVO and related analyses in younger sediments. The probability of success (Ps) for commercial production is less than 25% for wildcat wells. HC liquids (oil) cannot be discerned at all with industry acoustic tools. Industry exploration technology is mostly based on acoustic (seismic) methods. EM technologies have started to penetrate that market. Confidential 3 First Order Exploration, LLC
4. Direct Hydrocarbon Indicators DHIs are a collection of technologies that moredirectly measure the existence, depth and thickness and/or volume of hydrocarbons in the subsurface from the surface of the earth prior to drilling. We categorize technologies into three groups: Traditional ElectroMagnetic New Physics Confidential 4 First Order Exploration, LLC

10. First Order Exploration Model (FOEM)Workflow Scenarios Ideal – DHI driven exploration (built internally)Aerial DHI -> Area DHI -> Geology and/or Seismic -> Vertical DHI -> Drill Own 3D seismic without prospects built (built internally with our own or other 3D data ownership) Aerial DHI -> Area DHI -> Seismic and/orGeology -> Vertical DHI -> Drill Prospect/Project Already Built Traditionally with Geology and Seismic(First Order could evaluate and risk other company prospects and properties – a very efficient use of capital and time)Area DHI -> Vertical DHI -> Drill OR Vertical DHI -> Drill IndustrySeismic -> Geology -> Drill OR Geology ->Seismic -> Drill The FOEM reduces risk significantly early in the exploration or development processes. This will significantly reduce capital expenditures, prospect life-cycle, increase Ps and Return on Investment. Confidential 6 First Order Exploration, LLC

13. Sidebar – Current Upstream Risk AnalysisUnconventional is now Conventional: Resource Plays Upstream capital expenditures are guided by apparent risk profileof each project. Industry is willing to pay an EXTREME PREMIUM in upfront costs to reduce risk in “Resource Plays” Resource plays extract reserves from very low permeability host rocks. Reservoir is created through expensive massive fracturing operations. In 2010, resource plays dominated exploration budgets at the expense of conventional exploration. Money has flowed here because of apparent lower risk profile (but with lower reward as well). Industry is willing to pay >$10,000/acre for mineral rights in resource plays vs. $250/acre in conventional plays. Shale plays require massive land positions. Example of one spacing unit of 160 ac = $1,600,000 just in land costs Resource plays still have risk – especially at the outset (Tuscaloosa Marine Shale – a bust) and after a play has produced awhile. Average EURs are usually lower than press releases. Risked ROI probably < 3:1. Confidential 9 First Order Exploration, LLC

21. DHI Area Technologies Confidential 12 First Order Exploration, LLC
22. Direct Hydrocarbon Indicators Area Tools DHI Area tools solve 2 of the 3 dimensions necessary to find oil and gas. The area tool finds the surface or near surface evidence that an oil or gas field is at some depth below this indicator. Historically, “geochem” was used for this purpose where HCs are measured in the soil. This technique was proven to be undependable for prospects because of HC movement and soil residence of HCs is not predictable. Other more robust indicators have emerged through the years. Most are related to the “REDOX Cell” first published by Pirson in 1981. Tompkins further refined Pirson’s work in 1990 and 1993. These technologies measure the effects of the existence of a REDOX cell vertically above an oil or gas field or measure the current directly. Other Area tools unrelated to the REDOX cell have been used successfully but are less well understood such as technologies with Hydrocarbon Density, micro-gravity based technologies, nano-technologies and certain bizarre Russian technologies. These are intriguing and will take more work to fully understand. Confidential 13 First Order Exploration, LLC
23. The REDOX CellOil and gas fields produce measurable electrical currents The REDOX cell is simply the observation that above oil and gas fields there is a zone of increased negative charge (-Eh). The driving force for the zone of –Eh has been postulated as either themigration of HCs vertically from the field OR the existence of an electrical current originating from the oil/gas field flowing vertically to the surface of the earth. The manifestations of the REDOX cell are many. Most support the latter electrical theory.Additionally, this electrical current phenomena has been measured directly. This electrical current is measureable and has vector attributes that point in the oil field direction High and low frequencies have been measured (RIT, RECON and RP) Electrical current lowers Eh and Ph in the volume of rock above accumulations Russian investigators have measured Eh and Ph changes directly Effects seen above fields as anomalously bright seismic reflectors within the “diagenetic chimney” The current flow causes anomalous accumulation of reduced states of iron oxidesandiron sulfidesfrom the near surface to 3000’ in depth that have been measured in cuttings The Electrical Signal and derivative signatures are unique to Oil and Gas fields– a form of direct detection Many of the Area tool indicators have tremendous track records. DNME (IP) is 90% predictive in over 150 examples. Confidential 14 First Order Exploration, LLC

The IP anomalies are almost always associated with commercial oil or gas production. The excess pyrite deposition is caused by the REDOX cell currents. Confidential 26 First Order Exploration, LLC

39. Area DHIEL (Radiometrics) 1971 Sun Oil Co. Radiometric Survey in South Florida Sunniland Trend. Pre-drill predictions were 73% correct. Size of blue circle is relative to cumulative production for each well. Note potential undrilled prospects although map published in 1971. Clearly, this area is profoundly underexplored. Therefore, there are more exploration models to use in the area. It also means that DHIs are perfectly suited for this kind of area. More than 100 MMBOE have been produced from the Sunniland Trend. USGS (1995) estimates an additional 370 MMBOE remains to be found in South Florida.

43. Atmospheric Area DHI Tool – AEM The atmospheric tool measures some an EM manifestation of the oil and gas signal in the air above the field. It is postulated that the atmospheric effect is caused by live migrating hydrocarbons or perhaps CO2 that is given off by bacteria eating hydrocarbons . Alternatively, it may also be caused by the REDOX cell discharging and is another truly EM effect. Confidential 34 First Order Exploration, LLC

48. Multiple Area DHI Example The Camp Cooley #2R well was drilled in 1998 by Broughton Operating Corp. This is a world class gas well that produces from a Cotton Valley reef at 14,800 feet. This well was used as a test bed for many of the technologies that were tested. It is clear that good reservoirs will have a clear signal at the surface of the earth directly above the reservoir.

Multivariate analysis “clouded” the data into a “hydrocarbon” factor. Confidential 39 First Order Exploration, LLC
50. Vertical DHI Tools After the potentially productive area is identified with the Area DHIs, depth – the third dimension - needs to be quantified. There are far fewer vertical tools available compared to the area DHIs. These data define the prospect’s geology – depth, relative reservoir quality, thickness, trapping mechanism and, finally, an estimate of reserves can be approximated when combined with local production data. Confidential 40 First Order Exploration, LLC
51. Direct Hydrocarbon IndicatorsVertical Tools Vertical tools solve for the last dimension – Depth. Vertical signal not linked to horizontal signal - yet. Vertical DHIs all rely on the 80:1 ratio of the resistivity difference between the oil filled reservoir vs. the brine filled reservoir. This high S/N in the resistivity of the sediments affects EM signals distinctly. With proper correlation to wells with high quality reservoirs – productive and non-productive - predictive results are common. The time-tested EMT method for vertical HC identification is driven by natural energy sources. Confidential 41 First Order Exploration, LLC
52. Direct Hydrocarbon IndicatorsVertical Tools Resolves the object of the search – HCs in reservoirs. Accurate depth, relative porosity and fluid identification have been predicted from 800’ to 16,500’. DHI methods are much lower cost than seismic There are newer, less-developed technologies that have great potential that do use manmade energy sources. Potential seen in using common industry seismic equipment and setup with new seismic based fluids resolving technology. A near-perfect correlation of area and vertical tools is the desired results. The First OrderExploration Model combines the Area and Vertical DHIs with the traditional seismic and geological datasets. Confidential 42 First Order Exploration, LLC

69. Conclusions Fundamental observations indicate that both area and vertical DHIs are REAL and can mitigate exploration risk from every aspect of the process – land to drilling. First Order has investigated and used many of the available direct detection tools on the market First Order probably has perhaps the best understanding of how these tools work and where the may not work. First Order can design an economically phased program to evaluate large acreage blocks down to site specific prospects using the tools that are appropriate for the project Confidential 59 First Order Exploration, LLC
