The effect of gravitational compaction on estimation of vertical salt structure growth

摘要: Abstract The growth history of salt structures is reflected in the variation present thickness overlying and surrounding sediments relation to regional normal. A method for estimating pillow post-diapiric phase, including effect differential syn- post-depositional compaction, described. assumption that stratigraphic thinning established structural relief a result vertical movement alone inadequate. quantification true crest necessitates correction compaction basement subsidence. on-structure compared normal time-stratigraphic interval under consideration. On basis dominant porosity-reducing process, minimum maximum net can be calculated. assumed contained within these limits, probably closest growth. Two shallow diapirs Danish Basin exemplify relationship between observed subsidence, surface. average surface at Batum Mors phase are values diapir 731 m 1303 respectively, 276 996 thus emphasizing importance calculations structure implications storage hydrocarbons, radioactive chemical wastes, as well petroleum exploration, emphasized.
