This book was released on 2006 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: An important accomplishment was to understand the seismic velocity anisotropy resulting from the combined roles of depositional stratification and stress in unconsolidated sands. The report presents an experimental study of velocity anisotropy in unconsolidated sands at measured compressive stresses up to 40 bars, which correspond to the first hundred meters of the subsurface. Two types of velocity anisotropy are considered, that due to intrinsic textural anisotropy, and that due to stress anisotropy. We found that sand samples display a bi-linear dependence of velocity anisotropy with stress anisotropy. There exists a transition stress beyond which the stress-induced anisotropy outweighs the intrinsic anisotropy for three different sands.

This book was released on 2016-10-14 with total page 218 pages. Available in PDF, EPUB and Kindle. Book excerpt: Time Lapse Approach to Monitoring Oil, Gas, and CO2 Storage by Seismic Methods delivers a new technology to geoscientists, well logging experts, and reservoir engineers, giving them a new basis on which to influence decisions on oil and gas reservoir management. Named ACROSS (Accurately Controlled and Routinely Operated Signal System), this new evaluation method is presented to address more complex reservoirs, such as shale and heavy oil. The book also discusses prolonged production methods for enhanced oil recovery. The monitoring of storage zones for carbon capture are also included, all helping the petroleum and reservoir engineer to fully extend the life of a field and locate untapped pockets of additional oil and gas resources. Rounded out with case studies from locations such as Japan, Saudi Arabia, and Canada, this book will help readers, scientists, and engineers alike to better manage the life of their oil and gas resources and reservoirs.

Download or read book Effects of structural and stress anisotropy on velocity of low amplitude compression waves propagating along principal stress directions in dry sand written by H. Y. F. Chu and published by . This book was released on 1983 with total page 352 pages. Available in PDF, EPUB and Kindle. Book excerpt: A 7-ft cubical sample of dry sand was tested using the triaxial device constructed by Kopperman et al (1982) and Knox et al (1982). The sand was the same as that used by Kopperman and Knox. A new raining device was fabricated and used to construct this sand sample which resulted in a more uniform sample than prepared earlier. Improvements were also made to the excitation ports in order to have better control. Extensive tests were performed under the following different stress states: isotropic, biaxial and triaxial. In each case, velocities of P-waves propagating along all principal stress directions were measured. Results from these tests lead to the following conclusions: (1) the effect of stress history on P-wave velocity is negligible, (2) the sample can be treated as a cross-anisotropic material under isotropic confinement due to structural anisotropy, (3) complete anisotropy resulted by the coupling of stress anisotropy and structural anisotropy, and (4) P-wave velocity depends on the principal effective stress in the direction of propagation with principal stresses perpendicular to the direction of propagation having a negligible effect on velocity.
