Welcome. What is your question exactly? Something like "How do oil geodes form?"?

Also looks like Indiana isn't an unexpected spot to find oil in general based upon https://maps.lib.utexas.edu/maps/united_states/shale_gas_and_oil_plays-lower_48_states-2011.jpg ... (https://www.americangeosciences.org/critical-issues/maps/interactive-map-historical-oil-and-gas-production-united-states promises an even neater map charting production history... but doesn't work for me)

We have recently found some geodes with oil in them as well.

the term you are looking for is Enhydro agate, fluids trapped in crystls is not rare since crystals form in fluids. Oil is a lot less common than water but then thats true in general as well.
