Sedimentological Analysis of Well Data by the Example of the Dagi Horizon of the Northeastern Shelf of Sakhalin Island

Well logging methods provide important data on data on sedimentary structures, genesis of sedi-ments, and relations of the facies in sedimentary basins. This paper demonstrates the potential of sedimen-tological interpretation when applied to data from the formation microimagers (FMI). The study is...

Description
Summary:Well logging methods provide important data on data on sedimentary structures, genesis of sedi-ments, and relations of the facies in sedimentary basins. This paper demonstrates the potential of sedimen-tological interpretation when applied to data from the formation microimagers (FMI). The study is based on the results of the joint project on integrated analysis of wellbore images and core samples of the Neo-gene deposits of the northeastern shelf of Sakhalin Island between “Gazprom”, “Gazprom geologora-zvedka”, and Schlumberger Company. The image log represents 300 m of the well section, when 95 m are characterized by the core. The study included detailed matching of the core data with open hole logs as adjusted for core recovery, lithological description of the well section, structural and textural interpreta-tion of the images, facies analysis, orientation of the paleocurrent direction, and reconstruction of the depositional environments.
