Oil and Gas

Your Challenge

On-shore oil production uses various techniques for extracting oil or gas. Regardless of the chosen technique water is always extracted with it. This produced water constitutes the single largest waste stream for the oil and gas industry and the volume is set to increase as wells become exhausted. (The opposite is true for coal bed methane wells, which produce more water at the beginning of their lifecycles.) Produced water treatment involves removing hydrocarbons, oils and other pollutants so that the water may be disposed of or recovered.

Offshore oil production involves equipment at sea in a fixed location. Various types of platforms and vessels are employed for this duty supported by other craft for related activities such as supply and transportation. The offshore industry's need for water treatment can be classified as directly related to the production process (injection water, produced water treatment, wash water treatment) and indirectly related (ballast water treatment, sewage treatment, drinking water production, etc.)

Oil and gas companies need water in all stages of production. From process and feed water to treated wastewater and sludge, which must be filtered and clarified before being released back into the environment or recycled. The treated wastewater must meet specially prescribed criteria - either regulatory driven or process mandated.
