The major technical challenges include: increasing the frequency and power output of the sources to increase resolution, improving the imaging and inversion codes to handle problems such as aniso-
tropy, and decreasing the survey time through development of more rapid fielding sources and multi-
station receiver strings. Times for fielding and interpretation should decrease significantly as the method develops further.

Collaboration/Technology Transfer

This project is being performed by SNL in cooperation with Santerra

Corporation. Santerra plans to de-
velop the process for both envi-
ronmental and oil and gas appli-
cations. A patent, "Advanced Downhole Periodic Seismic Generator", is co-owned by DOE, SNL, and Richard Hills.
