petroleum production
A semisubmersible oil production platform operating in water 1,800 metres (6,000 feet) deep in the Campos basin, off the coast of Rio de Janeiro state, Brazil.
Petroleum production facilities separate oil, gas, water, and sediments before transport to prepare the product for safe and efficient distribution via pipeline or tanker.12
When petroleum is extracted, it is often accompanied by waterâwhich may contain salt and mineralsâas well as sediments and other undesirable components. Separating these materials is essential for several reasons:12
- Operational Integrity: Removing water and sediments prevents the formation of emulsions or solid hydrates, which can obstruct flow and damage equipment.12
- Safety and Maintenance: By discarding these impurities, operators reduce the risk of corrosion and buildup within pipelines, ensuring the infrastructure remains in optimal condition.2
- Standardization: Separation allows for the collection of "clean" crude oil and the processing of natural gas into consumer-ready products, such as natural gas liquids (NGLs).1
- Environmental Responsibility: Produced water is typically separated and reinjected into formations, keeping it isolated from freshwater aquifers.1
By utilizing surface equipment and treaters to isolate these fractions, facilities ensure that the petroleum meets the quality specifications required for transport and subsequent refining.12
