Genesis and reservoir preservation mechanism of 10 000‐m ultradeep dolomite in Chinese craton basin
Deep Underground Science and Engineering, EarlyView.Potential exploration target stratum of 10 000‐m ultradeep dolomite in Sichuan Basin and Tarim Basin, China. Abstract The 10 000‐m ultradeep dolomite reservoir holds significant potential as a successor field for future oil and gas exploration in China's marine craton basin.

Deep Underground Science and Engineering, EarlyView.A novel analytical method is proposed to evaluate the shear stress effect on the progressive compressive failure and microcrack growth direction in brittle rocks. The shear stress effect on the wing crack growth direction during the progressive compressive failure is determined. The initial crack angle effect on the y‐direction peak stress and the wing

The Non-Organic Theory of the Genesis of Petroleum [PDF]
arXiv, 1996 Recent advances in interdisciplinary fields as diverse as astrophysics, cosmogeophysics, nuclear geology, etc. have led to interesting developments in the non-organic theory of the genesis of petroleum. This theory, which holds that petroleum is of an abiogenic primordial origin, provides an explanation for certain features of petroleum geology that ...

Deep Underground Science and Engineering, EarlyView.Different failure modes observed in Tishreen tunnel include Floor heave, wall spalling, crashing of slab, and lining convergence reaching the failure limit. Abstract Squeezing phenomena can lead to severe loads in deep tunnels, especially in the presence of a low ratio of surrounding rock strength to overburden pressure.

Generating Realistic Geology Conditioned on Physical Measurements with Generative Adversarial Networks [PDF]
arXiv, 2018 An important problem in geostatistics is to build models of the subsurface of the Earth given physical measurements at sparse spatial locations. Typically, this is done using spatial interpolation methods or by reproducing patterns from a reference image.

Ore Geology Reviews, 2005 Abstract The Paishanlou gold deposit lies along the northern margin of North China Craton gold province, the third largest Au province in China. The deposit is mainly hosted in Archean metamorphic rocks of the Jianping Group and is structurally controlled by two sets of ductile shear zones.
