Abstract: Different from the stacked seismic data, pre-stack data includes abundant information about shear wave and density. Through inversing the shear wave and density information from the pre-stack data, we can determine oil-bearing properties from different… read more here.

Abstract: ABSTRACT To investigate the vertical and horizontal impact of reservoir scale on the amplitude‐versus‐offset characteristics, we conduct seismic numerical simulations on models containing spatially confined lithologic units with different scales. We find that the reservoir… read more here.

DOI: 10.1111/1365-2478.13035
Abstract: A novel approach of unconventional reservoir stress evaluation is proposed to enhance the accuracy of fracture development prediction. Differential horizontal stress ratio can reflect the stress characteristic of fractured reservoir. To calculate the differential horizontal… read more here.
