Hydrocarbon Exploration Using Unconventional Interpretation Techniques Reflection Seismology - Adeolu Aderoju Oyelowo G Bayowa Olatunbosun A Alao Kartoniert (TB)

Technology has been predicted as the last card in combating the ever increasing demand of our commodity oil and gas. Since the core technique used in exploring for Oil and Gas is the Reflection Seismology then modern approach to Seismic data acquisitions and interpretation is of prime essence. A powerful unconventional Interpretation tool Spectral decomposition has been used to visualize (in 3 - D) a thin sandstone reservoir in X - Field Niger Delta Nigeria. The study aimed at mapping thin sandstone beds which have been considered sub seismic or un-mapable using conventional interpretat ion methods. The suite of Well log data and seismic data were acquired and qualitatively and quantitatively interpreted using RocDok and OpendTect software. The identified thin beds were delineated perfectly using the spectral decomposition tool which was portrayed through amplitude variations. However new hydrocarbon prospects were identified through similarities of amplitude signature.
