Curtesy of Dr. Doug Haywick of the Uni of South Alabama, this lecture describes:
- the process of how organic material is converted into oil and gas
- the composition of oil and gas
- the migration of oil and gas from source rocks to reservoirs
The juicy stuff starts around 27:30 in although if you want to know a bit about types of roles geologists play in the oil and gas industry, start from around 8 mins in.
Cheers Doug.
