Exploration

• Seismic surveys are used to locate likely rock structures underground in which oil and gas might be found• Shock waves are fired into the ground. These bounce off layers of rock and reveal any structural domes that might contain oil

Recovery• Oil and gas are less dense than water and naturally rise up a well to the surface. In reality only 40-50% of the total will do so.

• To enhance recovery, a hole is drilled adjacent to the well and Gas/Water/Steam is pumped down (Injection). This helps to push the oil out of the rock and up into the well.
