Paleokarst systems are major carbonate reservoirs that can form significant and very large
oilfields. The Ordovician carbonate reservoirs of the Tahe Oilfield represent a special type of …

In recent years, petroleum exploration has extended from shallow to deep reservoirs in the
globle petroliferous basins. In contrast to conventional carbonate reservoirs, the fractures …

Abstract The Da'anzhai Member of the Jurassic Ziliujing formation in central Sichuan is a
typical tight-oil reservoir with porosity and permeability less than 2% and 0.1× 10–3 μm2 …

We present a path morphology method to separate total rock pore space into matrix,
fractures and vugs and derive their pore structure spectrum. Thus, we can achieve fine pore …

The cumulative expression of multistage deformation is complex multiperiod fractures, which
are commonly seen in tectonic zones. The Middle Triassic Leikoupo Formation in the …

This study outlines a probabilistic model based on artificial neural networks applied to the
deeply-buried karsted carbonates of the Ordovician Yingshan Formation, which represent …

Ultra-low porosity and permeability, inhomogeneous fracture distribution, and complex
storage space together make the effectiveness evaluation of tight carbonate reservoirs …

In order to solve the problem/address the issue of oil saturation reduction in the near‐
wellbore region of low‐temperature fractured reservoir in Fuyu oilfield, it is especially …

The characterization of carbonate reservoirs based on seismic and acoustic log data is
difficult due to their anisotropy. Complex pore structures are one of the major factors causing …

The high-resolution azimuthal resistivity laterolog response in a fractured formation was
numerically simulated using a three-dimensional finite element method. Simulation results …
