It starts long before the first drill bit touches the ground. Geologists use seismic data to locate underground reservoirs where crude oil has been trapped for millions of years.
Once a well is drilled and protected with steel casing, oil may initially flow to the surface W to the s under its own natural pressure. As reservoir pressure declines, pumps and artificial lift systems take over. In mature fields, enhanced oil recovery methods like steam, gas, or chemical injection help recover even more oil from the reservoir.
At the surface, the oil, gas, and water are separated before the crude oil is sent to refineries for processing.
From exploration to production, every stage depends on engineering, planning, and continuous monitoring.
