Case Studies in the Integration of Rock and Fluid

Interpretation

The geochemistry-petrophysics data showed that:

• Distinct geochemical fluid ratios correlate to stratigraphic benches within the Bone Spring and Wolfcamp formations stratigraphy.
• Petrophysical properties combined with the geochemical fluid variance highlights the generative organic-enriched stratigraphy versus the charged tight siltstones; as well as what and where the generated and expelled hydrocarbons migrated locally and regionally.
• Increased total porosity and permeability in the Wolfcamp XY correlates to charge from the underlying WFMP A.
• The WFMP is an organically-enriched, lower porosity, HC-filled zone with distinct geochemical fluid signatures.
• The WFMP B is an organically-lean, higher clay volume, mixed water, and HC-filled zone. The total porosity is dominated by micropores associated with clay volume. The fluid signature in these clay-prone turbidites is differentiable.
• The distinct signature changed in ratios between the WFMP B versus A benches. Those families can then be used to interpret what migrated and charged the WFMP XY and Bone Spring 3 sandstone intervals.
