An Engineer’s Perspective
A couple decades ago an international team of volcanologists arranged for the tag-on launch of a first generation orbiting gravimeter in order to study volcanism (the legitimate auspicious being pure scientific endeavor). While that intended function was successful, a much more important capability unexpectantly came to pass. Subsequent generations of these devices showed exactly where and to what extent natural gas, oil and coal were located as they have revealed progressively higher resolution images of Earth’s deep interior. Several more generations of these devices are possible and this explains the recent substantial increases in estimated recoverable oil and gas and coal for that matter. Meanwhile, fracking and horizontal drilling have enormously reduced the costs and surface-area-impact of fossil fuel recovery.
In the 1920’s we believed, quite honestly, that there were only 5, maybe 10 more years of recoverable oil. The simplistic plan was to make hay while the Sun shined…the economy was rocking.
