Over-Salt and Sub-Salt Gas Reservoir Mapping by EM Methods within the Salt Dome Region in Dniepr-Donetsk Depression

摘要

The detailed geophysical investigations within Western Radchenky area is presented. Main objective of the investigation is sub-salt exploration for gas reservoir over the area. The maps and cross-sections of anomalous polarized layer (APL) of the "gas-bearing layer" type were constructed on the geoelectric investigation data on Western Radchenky area. The salt sediments were finding and traced of as a result of geoelectric investigation. The salt dome borders were determine and The anomalous polarized layer of "gas" type of 21.0 m thickness is discovered in sub-salt at 3735 m depth in "terrigenous rocks".
