The middle Miocene M62 turbidite sequence in the deepwater Gulf of Mexico’s Marlin, Dorado, and Nile fields, was one of the earliest clastic deposits in the eastern Gulf of Mexico. Changes in depositional environments between the early Miocene and middle Miocene are the primary reasons for the occurrence of a more eastwardly clastic sediment deposition. Facies identified from conventional core were used to conduct a reservoir analysis for the M62 deposit. The M62 facies identified include: channel, levee/lobe, and overbank. Landmark’s DecisionSpace® software was used to conduct M62 facies correlations throughout the Marlin, Dorado, and Nile fields. Furthermore, geostatistical analysis was conducted with Landmark’s DecisionSpace® to allow for a less ambiguous interpretation of the M62 facies. Generation of cross-sections and facies maps assisted in understanding the facies distribution of the M62 sand deposit. Lastly, log derived acoustic impedance was compared with seismic derived relative acoustic impedance to investigate the possibility of prediction of facies laterally away from well-bores. This work will be valuable for future reservoir models of the M62 sand in the Marlin, Dorado, and Nile fields of Viosca Knoll, Deepwater Gulf of Mexico.
