Gravity in petroleum exploration
Revision as of 21:47, 2 July 2014 by FWhitehurst (talk | contribs)
Gravity offers significant applications to petroleum exploration. Gravity measurements are affected by changes in rock density. Surface gravity surveys and subsurface surveys made with a borehole gravity meter are effective in locating faults and geologic structures with density contrasts to their surroundings. The borehole gravity meter has broad application, from locating porosity in wildcats or through casing in old wells to monitoring fluid changes in productive reservoirs.
