January 31: So I ended up in Zhuozhou City about 120km from Beijing this week as a guest of the Geophysical Research Institute (GRI). I have trouble following the connection chart, and it changes, but to make a long, convoluted story seem short: it seems like the path is China National Petroleum Company (CNPC), which is then connected to PetroChina, which is then or also connected to the Bureau of Geophysical Processing (BGP), which is then the parent of GRI. GRI is the seismic processing workhorse and I think they do most of the seismic processing for the Chinese oilfields/companies.
