It takes time to deposit the sediments that eventually wil generate hydrocarbons, reservoirs and cap rocks. It takes time to deform strata to create traps and it takes time for hydrocarbons to migrate from their source area into the reservoirs
My layman’s understanding is that the time required is a matter of physics. Eg, the “mud problem” is about how long it takes for a given thickness of mud to solidify. Based on the physics that working engineers use in real projects today, very thick layers would need much longer times than YEC can allow. So any YEC model for oil exploration would need to posit different physics at work (and explain that change) or appeal to a miracle. The miracle itself would need a theological explanation - see The Burning Bush Reversed: the Unbiblical Miracles of Young Earth Creationism.
@faded_Glory can you elaborate on some of the ways that oil and gas models require long periods of time? Edit: Whoops, you actually did elaborate before this post got approved. Thanks!
