The concept of storing radioactive waste in geological formations calls for large quantities of concrete that will be in contact with the clay material of the engineered barriers as well as with the geological formation. France, Switzerland and Belgium are studying the option of clayey geological formations. The clay and cement media have very contrasted chemistries that will interact and lead ...

Abstract Underground CO 2 storage is a promising technology for mitigating climate change. In this vein, the subsurface condition was inherited lot of uncertainties that prevent success project. Therefore, study aims to build 3D model under geological enhancing capacity in Shahejie Formation (Es1), Nv32 block, China. The well logs, seismic data, and data were used construction 3-D petrophysical...

The current metadata modeling techniques can not meet the needs of knowledge conception expression, knowledge organization, and metadata semantic consistency in geological domain. This paper introduces ontology and integrates this theory to geological domain metadata modeling. It adopts the first order logic equivalent algorithm and defines the metadata extended model as a quaternion group whic...

The emergence and closure of the Isthmus of Panama had regional and global impacts that were rivalled by few other Cenozoic geological events. The closure of the Central American Seaway and the rise of the Isthmus had dramatic affects on climate and air and oceanic currents worldwide. Formation of the Isthmus also drove terrestrial biotic interchange, ending the isolation of South America by pe...

Unconventional oil and gas, represented by shale gas oil, have occupied an important position in global energy. The rapid growth of production shows great potential for the exploration development resources. Junggar basin, main oil-bearing basin China, is rich resources, so it practical significance to carry out systematic research on geological characteristics reservoirs this region. To end, p...

In many rock engineering projects, accurate identification of rock strength properties is very important. Uniaxial compressive strength is one of the most important features to describe the resistive behavior of rocks which is used as an important parameter in the design of structures especially underground openings. Determination of this parameter using direct methods, including uniaxial compr...

Water flooding is a well-known secondary mechanism for improving oil recovery. Conventional approach to evaluate the performance of a water flooding process (e.g. breakthrough and post breakthrough behavior) is to establish a reliable geological reservoir model, upscale it, and then perform flow simulations. To evaluate the uncertainty in the breakthrough time or post breakthrough behavior, thi...
