TECTONICS AND OVERPRESSURED FORMATIONS; Introduction; Faulting as a cause of overpressured formations; Shale diapirism (mud lumps, mud volcanoes); Prediction of tectonically caused overpressures by using resistivity and density measurements of associated shalesOrigin and distribution of overpressures in carbonate reservoirsKnowledge of the presence of abnormally-high pressure zones (AHFP) prior to drilling into them can prevent considerable economic losses and, possibly, save human lives. The various origins (undercompaction, tectonics, etc.) of AHFPs are discussed, followed by the description of predictive techniques in clastic, carbonate and salt-bearing formations. In addition to the well-logging predictive techniques, the authors discuss smectite-illite transformation and the chemistry of interstitial solutions. Other topics covered include (a) abnormally low formation pressures and subsidence, and (b) Developments in petroleum science ;50.Reservoir oil pressureOil well drillingGas well drillingReservoir oil pressure.Oil well drilling.Gas well drilling.622/.3382Chilingar George V.1929-439880Serebriakov V.
