Crude oil is a naturally occurring fossil fuel derived from the remains of dead organisms. Its composition includes a mixture of hydrocarbons, such as hydrogen and carbon atoms. Typically, crude oil is located in liquid form within underground reservoirs, occupying the small spaces within sedimentary rocks, and occasionally near the surface in oil sands.
Crude oil is often found alongside natural gas and saline water. While the terms crude oil and petroleum are frequently used interchangeably, it is important to note that petroleum encompasses both unrefined crude oil and refined petroleum products. It is also important to remember that crude oil is a non-renewable resource, and once depleted, it cannot be easily replaced.
