Abstract

Subsalt imaging and subsalt trap identification have been recognized for years as important but difficult exploration objectives. By using subsalt imaging technology the explorationist hopes to determine the depth of the subsalt structures and the presence or absence of structural closure associated with the subsalt prospect, thereby obtaining a realistic assessment of the risks involved with drilling a subsalt well. Target-oriented 3-D prestack depth migration is the most powerfuI tool available to assist the explorationist in the quest for hydrocarbon exploration below salt. In this paper we present a geophysical case study describing the steps taken to produce a nseful subsalt image.
