As a first step towards the numerical analysis of the stochastic primitive equations of the atmosphere and the oceans, the time discretization of these equations by an implicit Euler scheme is studied. From the deterministic point of view, the 3D primitive equations are studied in their full form on a general domain and with physically realistic boundary conditions. From the probabilistic viewpoint, this paper deals with a wide class of nonlinear, state dependent, white noise forcings which may be interpreted in either the Itor the Stratonovich sense. The proof of convergence of the Euler scheme,which is carried out within an abstract framework, covers the equations for the oceans, the atmosphere, the coupled oceanic-atmospheric system as well as other related Geophysical equations. The authors obtain the existence of solutions which are weak in both the PDE and probabilistic sense, a result which is new by itself to the best of our knowledge.

In this paper,we present an open python procedure with Jupyter notebook,for data extraction and vectorization of Geophysical explo ration profile.Constrained by observation routes and traffic conditions,Geophysical exploration profiles tend to bend curved roads for easy observation,however,it must be projected onto a straight line when data processing and analyzing.After projection,we don’t know the true position of the obtained crustal structure.Nonetheless,when the results used as an initial constraint condition for other Geophysical inversion,such as gravity inversion,we need to know the true position of the data rather than the distance to the starting point.We solved this problem by profile vectorization and reprojection.The method can be used for extraction data of various Geophysical exploration profiles,such as seismic reflection profiles,gravity profiles.

On August 26, 2019, the deep-hole integrated Geophysical observation system of the long-term observatory of the Chinese Continental Scientific Drilling project (CCSD) was successfully placed into the deep-hole and received signals in real time (Fig. 1). The deep-hole Geophysical observation system was installed to expected design depth: two sets of seismographs and three sets of geotherms were placed at the main hole of 1498 m, 2367 m, 3006 m and 3499 m respectively. The temperature of the deepest installation position is up to 98 ℃, the pressure is up to 35 MPa, and the minimum inner diameter is only 175 mm. It is the deepest deep-hole Geophysical observation system in China (Fig. 2).

As a bridge between the reservoir performance and the Geophysical well logging data,petrophysical measurements and its characterization are very important for the exploration and development of the unconventional resources in tight sandstone,carbonate and shale reservoirs.In this special issue of Energy Geoscience,“Recent advances in petrophysical and Geophysical characterization of unconventional resources”,we organized and invited authors to present recent advances in various subjects addressing new petrophysical characterizations and Geophysical models in unconventional reservoirs.

In order to study the ore-potential of the area around the Xiaohe rock body in southern Xiaoqinling, the authors chose 1:50 000 8 - Yi 3AgWBi stream sediment anomaly, Meso - Proterozoic Xiaohe rock body and Fl fault at the contact zone of Meso- Proterozoic Buandaokou Group to conduct geological, Geophysical and geochemical integrated exploration. Soil survey led to the discovery of the Zhangjikou 1 - Jia 3 Ag Au Sb Zn Pb As Co Cu Mo B composite anomaly characterized by relatively good element combination.
