Eagle Ford Formation Drill Core Data from Northeastern Mexico

Fernando Núñez-Useche's dataset provides geochemical and sedimentological data from two drill cores of the Cenomanian–Turonian Eagle Ford Formation in northeastern Mexico. The 36.1 MB dataset, last updated in April 2026, includes PDF and XLSX files analyzing depositional environments and hydrocarbon source-rock potential. The organic matter in the northern Sabinas Basin is described as typically post-mature.

Use Cases

• Modeling depositional history based on gamma-ray trends and sediment descriptions.
• Assessing hydrocarbon source-rock potential based on organic matter maturity and geochemical proxies.
• Correlating stratigraphic sequences with data from Texas based on vertical gamma-ray trends.
• Analyzing paleoenvironmental conditions (e.g., anoxia, eutrophication) from multi-proxy data.

Strengths

• Data is derived from a multi-proxy approach applied to two drill cores, suggesting multiple analytical methods.
• Includes a 36.1 MB dataset with files in both PDF (likely reports) and XLSX (likely tabular data) formats.
• Provides specific geological context, including the Cenomanian–Turonian interval and correlation with Texas data.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment for large-scale statistical modeling.
• Data reflects a specific geographic bias, focusing on two drill cores in northeastern Mexico.
