The exploration community, from the earth scientist to the investment manager, has surely recognized the recent surge of interest in the use of controlled source electromagnetics for offshore hydrocarbon detection and assessment. The targets, petroleum, natural gas and gas hydrate, are resistive zones in an otherwise conductive background. I trace the academic and commercial development of mari...

Gravity gradient data are currently enjoying a boost in popularity as their usefulness in both structural and stratigraphic petroleum exploration is re-discovered (i.e. Pawlowski, 1998) and as their use in mineral exploration is rapidly expanding. Gravity gradiometry’s ability to reject common-mode noise, directly measure quantities that must be calculated from potentially noisy data with stand...

For almost a century, various predictions have been made that the human race was imminently going to run out of available petroleum. The passing of time has proven all those predictions to have been utterly wrong. It is pointed out here how all such predictions have depended fundamentally upon an archaic hypothesis from the 18th century that petroleum somehow (miraculously) evolved from biologi...
