Completion and Production Phase After reaching the target depth, the well undergoes a completion process to prepare it for production. Oil is stored in tanks, gas is either re-injected to maintain reservoir pressure, processed for pipeline transport, or flared as a last resort, and water is treated or disposed of according to environmental regulations.

Maintenance, Monitoring, and Abandonment An active oil well requires continuous monitoring and regular maintenance to ensure long-term productivity and safety. Once a promising location is selected, the drilling process starts with a rotary drill rig.
Geologists and geophysicists analyze seismic data, rock samples, and geological maps to identify potential traps where oil and gas might accumulate. Geological Targeting and Drilling Process The journey of an oil well begins long before the first drill bit touches the ground.

Surface Facilities and Separation At the surface, the well stream is directed into separation facilities where the combined flow of oil, natural gas, and water is divided into its components. The returning slurry of mud and cuttings is passed over shale shakers and other separation equipment to clean the fluid for reuse and to monitor the rock being brought to the surface.
