Delineation of charged deltaic rock genetic types in algyo-2 hydrocarbon reservoir, hungary; Based on log curve shapes

Abstract

Most of the deltaic sandstone reservoirs exhibit complex lithofacies as well as petrophysical variations in both time and space. Facies analysis and reconstruction of facies patterns for the Algyo-2 reservoir rocks encountered in fourty five bore-holes have been elucidated, using the log curve shapes. Vertical profiles of the log response against the studied intervals were categorized for three superimposed, deltaic rock types in most bore-holes. Thereupon, the defined vertical units were mapped to show their geographical distribution. This will throw light on both the location of the palaeoshoreline and the deltaic phase relationships. Also, the defined facies marker horizons reflect the orientation, geometry and palaeogeographic distribution of the Algyo-2 sandstone.
