A major oil discovery in which state confirmed the anticline theory?

• A. Arkansas
• B. Texas
• C. Oklahoma
• D. Kansas

Answer: (C)

Oil tends to collect at the crest of a fold in the rocks, specifically in an anticline, where upward-curving layers create a trap beneath an impermeable cap rock. In Oklahoma, early large oil discoveries showed up right along these structural highs—creases in the sedimentary layers that formed anticlines. The oil pooled at the tops of these folds, exactly where the anticline model predicts it should, providing strong, practical evidence that such traps could hold hydrocarbons. These Oklahoma discoveries reinforced the idea that oil accumulates in anticlines, helping to validate the trapping mechanism and guiding future exploration toward folded structures.
