                                The phrase "the mother of all" was famously popularized by Saddam Hussein during the Gulf War, referring to a major battle. However, when applied to the petroleum industry, the term 'mother of all oil' is an idiomatic expression often referring to the largest, most significant, or most impressive example of its kind, rather than a single type of oil.
