Well, industrial and engineering science definitely qualifies as science, for example the history of learning how to convert crude oil into hundreds of different chemical products is a story of scientific development. The economic theory stuff doesn't hold up so well, however.

For example, it doesn't seem to matter much what socio-economic ideology a given country adheres to when it comes to extracting fossil fuels from the ground - socialist or capitalist, authoritarian dictatorship or liberal democracy, if they discover oil and gas they start drilling and pumping, without fail, and if they've got an excess, they try to sell it on the global market.
