This paper considers a new method for “pore scale” oil reservoir rock quantitative estimation. The is based on core sample X-ray tomography data analysis and can be directly used to both classify rocks by heterogeneity assess representativeness of the material collection. proposed criteria consider pore size arrangement in void thus related drainage effectiveness. classification at scale also w...

Barra Bonita reservoir is located in the Tietê River Basin - São Paulo state - 22 degrees 29' to 22 degrees 44' S and 48 degrees 10 degrees W and it is the first of a series of six large reservoirs in this river. Built up in 1963 with the aim to produce hydroelectricity this reservoir is utilized for several activities such as fish production, irrigation, navigation, tourism and recreation, bes...

Conglomerate reservoir is an important part of unconventional oil and gas resources, which has great developmental potential. However, its sedimentary environment structural background are complex, cementation types, gravel volume fraction shape quite different, leads to strong heterogeneity. When developing a conglomerate reservoir, it extremely difficult drill because It obtain the mechanical...

A new reservoir quality ternary plot (RQTP) of effective porosity, shale volume, and matrix is presented in this study. We show it to be a useful tool for first-order estimation the petrophysical zones classes each unit within reservoir. Subsequently, we combine RQTP results with permeability fracturing intensity data carbonate rocks provide better overall characterisation quality. The approach...

The research on pore structure and heterogeneity of shale reservoirs has always been a hotspot in the study unconventional reservoir characteristics. China is country dominated by continental shale. Compared with marine shale, lower maturity stronger heterogeneity. In this study, Sha-4 Liaohe Western Depression was selected for low-temperature nitrogen adsorption, scanning electron microscopy o...
