NORTHERN HUGOTON EMBAYMENT

WESTERN KANSAS

AEROMAGNETIC - BASEMENT STUDY

EDCON-PRJ is marketing a recently processed, detailed aeromagnetic survey of the Northern Hugoton Embayment. The area encompasses 92 townships in portions of Wallace, Greeley, Hamilton, Kearney, Wichita, and Logan Counties in western Kansas, and in portions of Prowers, Kiowa, and Cheyenne Counties in eastern Colorado. Data were acquired by Airmag Surveys, Inc., of Philadelphia and processed by EDCON-PRJ.

AEROMAGNETIC SURVEY SPECIFICATIONS

• Survey size: 6,925 miles
• Flight lines: East-West; 0.6-mile spacing
• Tie lines: North-South; 3-mile spacing
• Ground clearance: 500 feet
• Instrumentation: High-sensitivity, Cesium-vapor magnetometer; sampled at 0.25 seconds

DELIVERABLES

• Total Magnetic Intensity Contour map (IGRF-removed) at a scale of 1:96,000 on mylar
• Flight line location map at a scale of 1:96,000 on mylar

Color maps, on paper

• Total Magnetic Intensity
• Reduced-to-Pole Magnetic Intensity
• Second Vertical Derivative
• Susceptibility Map
• Forward Modeling Calculations

Black/White maps, on paper

• Horizontal Gradient of Reduced-to-Pole Magnetic Intensity
• Boundary picks of Horizontal Gradient
• Digital profile data and grids

OPTIONAL INTERPRETIVE WORK

An interpretation of the data set is proposed. The data analysis will focus on the determination of basement structures and lineaments using detailed line-profile and map analysis. Available public domain geological constraints, such as basement and Paleozoic well tops, will be incorporated in the interpretation. Modeling studies indicate a strong correlation between basement faults and structures and location and quality of Morrow channel deposits.

DELIVERABLES (Interpretation)

• Stacked profile display with inferred basement structural magnetic responses
• Residual magnetic anomaly map
• Shaded relief images of residual magnetics
• Basement fault and lineament interpretation overlay
• Magnetic basement structure map tied to existing well control

The integrated aeromagnetic-geologic interpretation of basement can be delivered approximately 90 days after commitment to purchase.
