Well you are right about Warwick, but wrong about Schlumberger, They are trying to use microwave in situ but certainly were not interested in the very short wavelenghts GRC was playing with due to penetration issues. You can be assured the have the expertise needed from Ratheon a world class microwave equipment producer, and do not need anything produced from the bumbling efforts of GRC or Hawks super cooled wave guide. On a scale of expertise, Ratheon would be a 10 and GRC would not even rate as they have only produced hot air.
