Shale oil is an oil distilled from shales and used as fuel
crude oil
Basestock is refined petroleum oil with no additives.
The British Petroleum(BP) who are responsible for the oil spill but they are still the biggest company regarding the oil spills.
The largest petroleum company in the world is the Saudi Arabian Oil Company, not Shell, as the original answer stated. The top 10 petroleum companies in the world are as follows according to petrostrategies.org (http://www.petrostrategies.org/Links/Worlds_Largest_Oil_and_Gas_Companies_Sites.htm):Saudi Arabian Oil Company (Saudi Arabia)National Iranian Oil Company (Iran)Qatar General Petroleum Corporation (Qatar)Iraq National Oil Company (Iraq)Petroleos de Venezuela.S.A.

Yes. According to the US government's official energy statistics, 40% of Murphy Oil's 2007 imports came from Persian Gulf countries: http://www.eia.doe.gov/pub/oil_gas/petroleum/data_publications/company_level_imports/current/summary2007.html No. The above answer is outdated. For the year 2011 (January - December 2011) Murphy Oil did not import any crude oil from Persian Gulf countries. Web verification: http://www.eia.gov/petroleum/imports/companylevel/summary.cfm

A material that contains hard-to-mine petroleum is oil shale. Oil shale is a sedimentary rock that contains kerogen, a solid organic material that can be converted into synthetic crude oil through processes like pyrolysis. Extracting petroleum from oil shale is more challenging and costly compared to conventional oil extraction due to the need for extensive heating and processing. As a result, while it represents a significant potential resource, its economic viability often depends on oil prices and technological advancements.

There are two possibilities here: crude oil or natural gas. It's possible that oil shale and tar sands could be thought of as unrefined petroleum sources as well.
Oil shale is a type of rock that contains kerogen, a precursor to oil. When heated, the kerogen in oil shale can be converted into oil and gas. This process is known as pyrolysis.
