yes but your comparison is total bullshit drake is nothing but a dilution machine.grdo has never dumped heavly into pr's....take two seconds and compare.the tool is not being marketed to the big boys...they don't need it,DUH!! this is directed towards the multitudes of small outfits that can benefit from extracting existing rather than new drilling.what process do the big boys use to extract heavy oil???or do they leave it?i don't know..do you,just asking. may not pay for the big boys with higher overhead but a lot of people got to be very rich on smaller production.
