Here, we present observations of biogeochemical alteration of wellbore cement after interactions with H 2 . Experiments were conducted with a wellbore cement core and shale submerged in synthetic formation brine...

... money and time on science projects. After all, the shale deposits are widespread and no large variation in production was expected. However, this was proven to be unrealistic and the value of seismic data are now recognized. Seismic data, especially attributes derived from pre-stack data are now...

... will often face the challenges of requiring large sample sizes, time consumption and accuracy in interpretation. It is also difficult to interpret and evaluate the pore scale, micro-mechanical, behavior of shale rocks. The elastic properties of a shale rock are mainly governed by the relative amount of each...

... Abstract Kerogen, which is the main constituent of organic matter and plays an important role in hydrocarbon adsorption behavior in shale. In this paper, molecular dynamic (MD) simulation was performed to characterize the adsorption behavior of hydrocarbons in kerogen pores. This study showed...

.... Abstract This paper presents the results of a pilot project to predict the production potential of locations in the Eagle Ford Shale and Bakken Shale formations. The approach uses DNA analysis of shallow soil samples to determine the present mix of species which are affected by vertical microseepage from...

Lastly, a seismic brittleness was estimated based on the dynamic geomechanical properties. The estimated elastic properties...

... Abstract The transport of methane in shale is complicated by the heterogeneous pore structure, inhomogeneous surface properties arising from complex mineralogy, and the presence of adsorbed/bound water. With such complexities, the contribution of advection and diffusion to the transport...

... goals of this study are to develop a multi-physics understanding of not only the reservoir section but also the shale member, while incorporating anisotropic behavior and correlating pressure-dependent geophysical characteristics to geological attributes. In this study, four samples were collected from...
