Exploring for and producing oil and natural gas requires drilling wells – often more than a mile deep – to bring oil and natural gas from deep underground to the surface. Occidental drills more than a thousand wells each year at our operations in the United States, Middle East and Latin America. Excellence in well design and drilling execution are key to our production success.
Once a well is drilled, steel pipe is placed in the well and cemented in place. The cemented pipe keeps the hole open for the life of the well and seals the formations that hold the oil and gas. To complete the well, holes are shot through the pipe and cement to allow the oil and gas to flow into the well under controlled conditions.
Smaller, removable pipe, called “tubing,” is installed to contain the flow of oil and gas to the surface. The tubing protects the permanent steel pipe from wear and corrosion. The steel pipe, tubing and high-pressure valves at the surface contain and control the oil and gas.
We use a variety of equipment and methods, such as artificial lift, to ensure that the fluids are brought to the surface efficiently.
