Abstract
This work presents a survey of opportunities for cleaner production applied to water used in the processes of exploration and production of oil on shore. The study consisted of literature review and investigative forays in the region of the state of Rio Grande do Norte. Opportunities arose in the following order of priority: eliminating at source, minimizing the consumption, recycling or reuse internal or external, treatment and final disposal. The results point to projects associated with the reduction of leaks in water pumping systems for the formulation of captured fluids, reduction of leakage of steam, use of brackish / saline uptake from deeper wells to replace the fresh water wells to capture ; use / reuse (external) water drains, replacing the freshwater abstracted and used for injection, use of ocean water (captured from the sea) in replacement of freshwater abstracted for the purpose of secondary recovery; adoption of equipment / system increase in oil resources DOWS Downhole Oil Water Separation and greater automation system with the use of smart wells and fields.
