Abstract
The porosity studies results of the sedimentary rocks from the South Barents Sea Basin are discussed. The porosity was estimated by several methods including well logging analysis and core measurements. As a result of the research generalized porosity trends with depth were obtained for the upper part of the basin (about 3-4 km). Main factors affecting the porosity and permeability of siliciclastic rocks were assessed. The greatest influence on the porosity has a compaction (depth). Also, both porosity and permeability depend on the cement type and grain size. These patterns have been used to study the processes of diagenesis, estimation of uplift/erosion, basin burial and petroleum systems modeling.
