The principal waste streams have been identified from the production operations of all Shell Exploration & Production (E&P) companies. A phased approach has been identified to meet our target of eliminating over time all emissions, effluents and discharges that have a negative impact on the environment.
In the short/medium term, changes in operational procedures, together with "end of pipe" technology will be used to reduce emissions. In the longer term, fundamental changes to the production process will be required to eliminate the problem as far as possible at source, to re-use waste streams within the process and return any remaining unwanted material to the producing reservoir, without additional contamination.
Carbon dioxide is currently regarded as a special case and will be reduced by minimising the amount of energy consumed and /or wasted in the production process.
