Geoscience Division WHEN TIME IS AS VALUABLE AS THE RESOURCES
Outline• Technology• Instruments • Provided Information
•Important Factors• Producing accurate data
•Performance• Saving money and time versus a conventional lab
•Solutions• Information that matters
•Reservoirs• Where we can use these services
•Anticipation vs. Reality• Proven reservoir characteristics
Cutting Edge TechnologyMoving into the next era of Oil and Gas
Program Pyrolysis: Hawk
Analysis Provides:• Hydrocarbons in place (S1)• Hydrocarbon potential (S2)• Organic Carbon Dioxide (S3)• Residual Carbon (S4)• Total Organic Carbon (TOC)• Thermal Maturity (Tmax)
Why are these important to you?
Vital Information for Production
Information:• Pay Zones• Secondary Pay Zones•Migration• Kerogen Typing•Quantity of Hydrocarbons
X-Ray Diffraction: Mineralogy
Analysis Provides:• Quantitative Mineralogy • Quartz to Pyrite, plus any unknowns• Total Clays• Accurately define Formation Tops• Brittleness Index• Lab grade goniometer instrument
Why are these important to you?
Precise Answers for Completions
Information:• Locations to land Horizontally in
Production Zones• Brittleness to develop more efficient
Fracturing Plans• Determine possible Fluid Sensitive
minerals• Peace of mind knowing where you
are in the well bore
X-Ray Fluorescence: Elemental
Analysis Provides:• Compositional measurement of
31 elements (12 majors/19 traces)• Reservoir Stratigraphy• Paleoredox and Productivity
proxies• Elemental Signature of Pay Zone• Vacuumed sealed unit
Atomically Sound Answers
Information:• More accurate Gamma Ray in
horizontals vs. wireline• Wellbore placement in
horizontals• Brittleness to help completion
decisions• Modeled mineralogy
Pseudo Science vs Real Science•Providing reproducible data• Standard Operating Procedures for every step
•Sample Preparation• Using state of the art techniques• Prevents the over crushing of carbonates• Homogenized samples allow for accurate analysis• Eliminates human error
•Personnel• Professionally trained• Years of experience• Passionate about the geosciences
Performance MattersGEOSCIENCE DIVISION
•Produces an average of 60 XRD sample per day ($15k worth of data per day)
•Program Pyrolysis is completed 3 times faster without sacrificing the data
•Standards are used at a regular interval to ensure the highest quality of data
•Degreed professionals with years of experience
CONVENTIONAL LAB
•Samples could take up to 4 weeks or longer to complete
•Use of antiquated technology to produce results that can be affected by barometric changes
•Use of standards are only applied to certain instruments for a limited amount of time
•Who knows who is handling your samples
Providing SolutionsEXPLORATION
•Complete understanding of the entire well that a core cannot produce
•Identify important geological features in new lease areas
•Locate the best zones for production while choosing the right drilling fluid
•Historical data can be used with current drilling operations to provide a comprehensive understanding of leases
PRODUCTION
•Define entire organic zones to optimize production
•Brittleness zones outlined for efficient hydraulic fracture planning
•Well bore placement in horizontals
•Determining areas of better production in leases
ReservoirsConventional
Identification of core point and total depth in vertical wellsDetect faults in the presence of sand to sand or clay to clay contacts
UnconventionalHeterogeneity can be difficult to find sweet spotsCan streamline projects by providing critical answers for completions
High Temp/High PressureAble to go where no other tools can due to extreme conditionsProvides real time reservoir information
Carbonate Low gamma responses can be difficult for steering Able to determine mineralogy changes Elemental data can provide more detailed changes in trace elements such as Sr, Rb, Y, Nb, and Th
Anticipation vs Reality•Going into a well program we have a basic understanding of the geology and the reservoirs/source rock locations.
•Reality is that geology can change in very short distance that can drastically alter how the well is landed horizontally and completed.
•In the examples to follow we evaluated the well with all three instruments.
•We mapped the well bore elementally and provided free oil and organics after locating the zones of most interest.
•All interpretations were done at near real time during the drilling procedures to ensure the fastest evaluation for possible drilling corrections.
Anticipation •Area classified as “Wildcat”
•Client anticipated pay zone in general area that was near previous wells.
•Landing point was predetermined before drilling due to expected lithology.
Reality•Main reservoir was located 110’ below the anticipated depth.
•A larger section of free oil was obtainable with a new landing point.
•Client tapped into both outlined reservoirs and was able to save the well from low IP.
•4 potential pay zones were located for production and future development planning.
•Migrated oil was also located while drilling the curve that was not reflected in the pilot hole analysis.
