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. Sensors track pressure, temperature, and flow rates, while periodic interventions may be necessary to clean blockages or replace worn components.

Once a promising location is selected, the drilling process starts with a rotary drill rig. Finally, a series of valves and tubing—collectively known as the Christmas tree—are installed on the surface to control the flow, pressure, and direction of the produced oil and gas.
This initial separation is crucial for efficient handling, storage, and further processing of each product. 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.

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. Geologists and geophysicists analyze seismic data, rock samples, and geological maps to identify potential traps where oil and gas might accumulate.
