There are two different methods of producing oil from oil sands: open-pit mining and in situ. Bitumen that is close to the surface (less than 75 metres) is mined. Approximately 20% of oil sands are recoverable through open-pit mining. Bitumen is extremely thick and too heavy to flow or be pumped, Oil sands, generally speaking, are rocks that contain bitumen. Primarily, these rocks are sandstone, although limestone can also be impregnated with bitumen. The largest oil sands resource in Alabama is within the Hartselle Sandstone, and has been known and studied since at least the 1890s.

This is known as in situ production. Unprocessed oil sands contain 3–18% bitumen by weight, along with 2–10% water and 80–85% mineral matter (sand, clay, etc.). Bitumen is composed chiefly of polycyclic aromatic hydrocarbons (PAHs), sulfur, lead, mercury, arsenic, nickel, vanadium, chromium, and selenium. Tar sands are a fossil fuel resource. It is composed of sand, claw, water, and bitumen, which is an oil that is black and viscous. These sands can be mined, and then processed, to remove the bitumen. Once processed, then bitumen can be then refined into oil.

The oil sands or tar sands, are a mixture of sand, water, clay and a type of oil called bitumen. Thanks to innovation and technology we can recover oil from the oil sands, providing energy security for the future. Oil sands are a mixture of sand, water and  bitumen  (oil that is too heavy or thick to flow on its own).
