Atoka Geochemical6855 Havana St. #400, Centennial, Colorado, United States

The Use Of Surface Geochemistry For Petroleum Exploration Was First Applied By The Russians In 1930s Looking For Cheap, Effective Ways To Target Oil Traps. Following The Oil Price Collapse In 1986, I Saw The Practical Sense These Methods Made In The US. Atoka WAS Founded On The Principle That An Operator Does Not Need To Spend An Exorbitant Amount Of Money To Significantly Decrease Dryhole Risk. I Focused On Creating A Company Environment Of Quality And Collaboration That Persist Today. Unlike Our Competitors, We Forge Meaningful Partnerships With Operators, And Work With Them To Identify How ATOKAs Services Can Best Support Their Exploration Effort. As A Scientist And E&P Operator Myself, I Stand Behind These Methods And Refuse To Drill Where Surface Geochem Anomalies Are Not Present.     

SURFACE GEOCHEMISTRY SERVICES

 Surface Geochemical Techniques To Detect These Changes In Chemistry Have Been Used With Success Since The 1930S.  First Developed By The Russians As A Way To Compete With The Larger Budgets Of The American Oil Industry.  Their Low Cost Taken Together With Their Significant Increase In Drilling Accuracy Yield, Make Them A Powerful Tool For Petroleum Exploration. 

Magnetic Susceptibility

The Magnetic Susceptibility Of Soil Minerals Is Discussed, And In Particular That Of The Ferrimagnetic Minerals, Maghemite, Magnetite, And The Titanomagnetites Since One Or More Of These Usually Dominates Soil Magnetic Properties. The Magnetic Susceptibility Of Soil Depends On The Shape, Size, And Concentration Of These Minerals As Well As On The Method Of Measurement. Measurements Performed In A Weak Alternating Magnetic Field Are The Most Reliable.  The Identification, Formation, And Occurrence Of Soil Maghemite Is Considered In Detail Since It Is Usually Of Pedogenic Origin And Occurs In (Magnetically) Detectable Amounts In Most Soils. Moderate Concentrations (>1 Per Cent) Of Magnetite Or Titanomagnetite In Soils May Be Accurately Measured If Some Of The Material Is First Magnetically Separated And Its Susceptibility Determined. An Example Is Given Of The Use Of Susceptibility Measurements. Pedogenic Maghemite May Be Determined In Soils Developed From Parent Materials Of Low Susceptibility. A Very Rough Value Of 8.8 × 10−4 M3 Kg−1 Is Suggested For The Mass Susceptibility Of Such Maghemite (Excluding Magnetic Concretions).  Although Susceptibility Has Been Suggested As An Indicator Of Soil Forming Processes, This Is Only Possible Within An Area Containing Fairly Uniform Parent Material.
