Quick Look at the Reoccupation and Installation of Seismic Stations at the NNSS
Description:
Over the last couple of years, the Nevada National Security Sites (NNSS) has increased the network footprint through the installation of several new seismic stations and by reoccupying historic locations. The overarching goal is to improve our coverage for modern experiments; however, there is also a desire to understand the integration of historic measurements to modern systems. Although some of the historic locations have been easily reoccupied, some locations prove a bit more challenging to locate. Additionally, we have attempted to occupy wells that were not designed for seismic systems. These challenges provide a unique opportunity to compare site and system effects in the modern data. We will discuss the challenges of these installations and compare common signals and noise that are recorded by the modern and historic systems. We have also completed huddle tests in various locations that compare the downhole and surface signals. We show, through modeling, the difference in offset of 100 and 200 m gaps to understand the potential contributions of site effects with re-occupied locations. With the various types of sensors and data recorders, we have a robust data set to help understand some of the issues facing network operators. We are looking at ways to rapidly identify the quality of new stations and ensure that the continuity between historic measurements is maintained in our network.
