Where do you go to find sources for an academic level paper?
Your best bets are library databases, specific academic journals, and specific organizations. If something you want is not available directly (for example, an article you want is behind a paywall), you can ask the library to obtain it for you via interlibrary loan (a mechanism where libraries lend materials to other libraries).
Are you looking for statistics?
Statistics tend to be spread out all over the place, so you will need to look around. Many organizations produce statistical reports which can be very useful, and you can find these by running a web search like this: [topic] organizations statistics.
Example: petroleum organization statistics. This search produces results such as this list of statistical resources related to petroleum, from the Library of Congress.
You can also use the library's Statista database, a database that collects statistics from a variety of sources.
