Abstract
Knowledge of salt boundary locations at the salt flanks and base is critically important for updating velocity models, getting better sub-surface images, estimating a reservoir size, and minimizing drilling risks for exploration and development wells in and near the salt. We have developed a Reflection Salt Proximity method to delineate the salt-sediment boundary. This method utilizes the reflected P waves off the salt face to calculate the Salt Reflection Points by measuring arrival times, azimuths, and vertical angles of the reflected PP waves with a sediment velocity model. This approach is complementary to the salt proximity migration, sediment proximity, and conventional salt proximity methods. An example in the Gulf of Mexico is used to demonstrate the method and to present the calculated salt reflection points, which are consistent with those results obtained from the conventional salt proximity surveys.
