When this pressure depletes, operators often inject water or gas into the reservoir to maintain pressure and force additional oil toward the wellbore, termed secondary recovery. An oil well is a man-made shaft drilled into subterranean reservoirs to extract crude oil and natural gas trapped beneath the Earth's surface.
Well Completion Process Preparing Production
The process begins long before any drilling occurs, involving extensive geological surveys and seismic imaging to identify promising formations where hydrocarbons have accumulated over millions of years. Surface Infrastructure and Separation At the surface, the flowing wellhead connects to a complex network of valves, pipelines, and separators that divide the raw mixture of oil, natural gas, and produced water.
As the industry evolves, digital twins and autonomous rigs are becoming more prevalent, improving safety, efficiency, and precision while adhering to increasingly stringent environmental regulations worldwide. Maintenance, Monitoring, and Abandonment Throughout the productive life of a well, continuous monitoring via digital sensors and periodic wireline logging helps operators assess borehole integrity, track corrosion, and manage water encroachment.
Well Completion Process Preparing Production
From Geological Survey to Drill Bit Before a single drill bit touches the earth, teams of geologists and geophysicists analyze rock samples, seismic data, and satellite imagery to map potential oil traps. High-pressure separators use gravity and mechanical devices to split these components, with the gas often being compressed and sent through gathering lines, while the oil is temporarily stored in tanks.
