The Acoustic Characteristics of Tectonically Deformed Coal in Huaibei Coalfield
Energies, 2023 Tectonically deformed coal (TDC) is closely related to gas outbursts. Since TDC exploration is an essential objective for coalfield exploration, it is of great significance to study the petrophysical properties of TDCs and explore their differences. This

Improving Petrophysical Interpretation of Conventional Log by Determination of Real Bed Boundaries [PDF]
Journal of Sciences, Islamic Republic of Iran, 2017 Proper determination of bed boundaries in layered reservoirs is vital for accurate petrophysical interpretation of conventional logs. In the wellbore, logs continuously measure physical properties of reservoir while the properties change stepwise ...
