Compared with normal pressured shales, which one of the following features can be found in overpressured shales? O A. Lower dens
ities, and higher thermal gradient O B. Lower densities, and lower thermal gradient ° C. Higher densities, and higher thermal gradient O D. Higher densities, and lower thermal gradient
Over pressured zones during penetrating are those zones where development liquid weight (higher than expected) surpasses the mud weight. These are liable for victories.
The pore liquid substance in shales of the over constrained zone is higher than the ordinary compelled shales. That implies, the porosity of shales in over pressured zone is higher as well thus the thickness of the over forced zones are lower than the ordinary influenced shales.
Because of the nearness of more liquids in the pores of an over constrained shale, the warmth produced because of penetrating behaviors gradually in over influenced shale than a shale in typical weight zones. Accordingly, warm inclination will be higher in over forced shales.
