Frio pilot is in the final stages of post-injection monitoring
for the second injection at this site. GCCC partners have played
key roles in this project from the start in 2003, when BP provided
guidance on scope and engineering issues.Schlumberger
has processing RST logs from the second experiment, which has
proven-up RST as tool of choice for well-based CO2 plume monitoring.
has just conducted sampling with the cased hole formation tester
to test this tool as a method to assess well integrity. Praxair
has conducted two tests with their surface perfluorocarbon tracer
“Seeper trace” and documented that this technology
works in geologic storage environments and that the Frio wells
are not leak sources.
second test was conducted with the press observing (ABC News,
Antonio Express-News, and Houston Chronicle) thus achieving the
goal of demonstrating to the public that this technology is mature.
Final activities at the Frio site will be a VSP survey in 2008,
which is a low-budget surface to well seismic survey designed
to measure the maximum subsurface spread of the injected CO2.
