Via sealed boreholes drilled into the reservoir - permable rocks trapped below an inpervious, impermeable cap rock. Once the gas pressure in the reservoir falls too far for it to push the crude oil to the surface, water in pumped down a parallel well to displace the remaining iol up through the production well.

One point - the oil is not in the crust. It is in sedimentary rock covering the crust.

How are petroleum and natural gas removed from the earths crust?

Petroleum and natural gas are removed from the Earth's crust through drilling wells into underground reservoirs where these resources are trapped. Once a well is drilled, the oil and gas are brought to the surface using a combination of pressure from the reservoir and artificial lifting mechanisms like pumps or gas lift systems. The extracted petroleum and natural gas are then processed and refined for various uses.
