Increasing efficiency in the production of commodity oil in offshore fields and produced water utilization

The presence of aggressive produced water and sand-clay mixtures in the oil entering oil gathering points causes pollution of technological tanks. Despite the use of precipitators or three-phase, four-phase separators to separate water, salt and solid particles from oil, solid particles consisting of sand-clay mixtures enter crude oil, water and commodity oil gathering tanks. Due to stagnation in the tanks, water, salt and solid particles separate from the oil and settle to the bottom. To remove water and solid particles from the oil storage tanks, a set of DN 80 mm siphon taps and a set of DN 150 mm cleaning pipes are provided, which cannot cope with the task of cleaning the tanks from bottom sediments. Cleaning oil tanks from bottom sediments in offshore fields is a particularly complex process from an environmental protection perspective.
To prevent these situations, the number of cleaning pipes along the perimeter of the storage tanks should be increased. Inhibitors should be added to the water to reduce the aggressiveness of the water injected into the formation.
