Determine the present availability of pertinent hydrogeological data. Interpret this data as far as possible and outline effects of the groundwater systems on oil recovery operations and vice versa
Resource
Provide background information on an extensive number of water quality parameters to enable the employment of predictive techniques and at the same time to understand natural water quality loadings
