.... The main objective of this study was to develop anisotropic rock physics modeling of the Bakken formation to assess the elastic behavior and determine the key parameters controlling the velocity dispersion with respect to layering. Maturity effect was also investigated by including kerogen content...

.... The experimental results show that the clay kerogen combination distributed in the inorganic mineral background is the main controlling factor of the anisotropy of the target reservoir. Therefore, using the anisotropic differential equivalent medium model (DEM), the clay kerogen combination is established...

... milled samples to understand the nanometer and micrometer scale pore properties and pore geometry. Results show that with maturation, pores within the kerogen marcerals changed in size, frequency and shape. Linking the NMR pore and SEM pores provided an understanding of the pore properties and geometry...

... economically. To fulfill this aim, more understanding about shale rocks and also one of their main constituent know as organic matter is crucial. Since it has been well established that the quantities of hydrocarbon generation are a function of kerogen type and level of thermal maturity. Moreover, the presence...

.... This combination of equipment truly allowed us to observe the change in geomechanical properties due to the kerogen decomposition for each of the tested samples. The technique’s applicability was proved by measuring geomechanical properties of shale samples and we also determined the change in geomechanical...

... velocity, which was identical to the decrease in porosity and density. In the over-mature stage, where the pore space increased by ~29%, and the solid skeleton included kerogen residue and unaltered minerals, S wave velocity increased by ~19% and P wave velocity decreased by ~16%. We concluded...

... Abstract: Laboratory nanoindentation tests have indicated that kerogen demonstrates strain-softening, ductile mechanical behavior when subjected to tensile load. An implication of this observation is that kerogen can have non-negligible or very significant effects on initiation, opening...

INTRODUCTION Oil shales consist of the host rock and organic material (kerogen). Oil Shales are shallow formations near the surface down to about 1 Km. The kerogen...

... continuous static properties throughout the middle Bakken. We have also reanalyzed previous data taken in the Bakken shales and developed a strong correlation between the stiffness tensor and kerogen content. The results show that the high kerogen content in the shales coupled with their tendency to be over...
