... the uncertainty of static corrections. Upholes are the primary data source for all near-surface models in Saudi Arabia, with some 42,000 upholes acquired every 4 km along the 2D seismic acquisition line grid. For most of the exploration areas in Saudi Arabia, statics are derived from the single layer model from...

This initial two-layer model was further refined by adding extra contol points to define the near-surface geology much more accurately than before. While this model defined...
