Variability of estimated ultimate recovery in shale oil and shale gas accumulations in the U.S.
Variability of mean EURs within and between unconventional reservoirs is becoming more apparent as thousands of wells are drilled and oil and gas is produced from unconventional low-permeability reservoirs. Production from many of these reservoirs shows that there is spatial heterogeneity of EURs, which is mainly related to geologic characteristics. The more refined view of spatial heterogeneity r
