Abstract

Summary

Lateral changes of lithology can reduce the reliability and efficiency of geosteering when using only reference wells. Using 3D seismic data in addition to reference vertical wells can improve the efficiency of horizontal wells planning and geosteering. The oil field considered in this study is covered by 3D seismic survey and 6 exploration wells. The Neocomian terrigenous reservoir is being developed with horizontal wells Seismic-well-tie show that lithology changes within Neocomian reservoir can lead to time shift between stratigraphic well top and seismic reflection. Seismic facies mapping was performed using seismic attributes and verified by horizontal wells data. Result seismic facies map can be used for optimal well placement
