“I was trolling the SEG abstracts and came across your time domain GOM data match and I am very impressed. …In the literature there are very few examples of such a good data match. We are quite interested in this because we want to calibrate our own work. “ Email sent to GTS Sept 11, 2013 from a senior Chevron scientist

“My name is Ya******, a research geophysicist working (under Dr. Yi Luo) at Saudi Aramco Houston Research Center…. Early this year, I was working with Dongliang Zhang and Prof. Jerry Schuster for multiples least square migration code. I understand the major part of this code comes from your contribution. I am very impressed by your accomplishments……..If you don’t mind, may I ask you to send me your 3D acoustic mmi code?” (Aramco email sent by Dr. Ya**** & relayed to GTS Sept 21, 2013)

“….We have started running your FWI code in Dhahran, and re-generated your test example. It is a great package. When I submit the job how do I instruct the code to run across multiple nodes using MPI? “(Aramco email sent by Dr. To**** May 2013)

Jerry:I want to learn more about your land streamer experiments, this could be very important. Are there more info for this experiments. Thanks Y*** (email April 7, 2013 from Aramco senior scientist)

Steven Chu, Nobel Prize winner in Physics, said that the way to do great science is to

“…put yourself in the position to do experiments that could be important .”
