Abstract

Well logs and data are integrated in most reservoir exploration to provide a reservoir description, the depth and width of the holding subsurface structure are two reservoir parameters that must be understood in order to quantify viable hydrocarbon reservoirs, these metrics are important because they offer suitable contributions for measuring reservoir volume, the objective is to cross-plot well logs with seismic amplitude to provide reservoir characteristics, map reservoir pay zones and determine reservoir depth and thickness, the method applied in this research were collection of set of data consisting of ten wells information cutting across the Agbada formation and 3D post-stack seismic data acquired from the Niger Delta, set of well log suites and software (Word, Excel and Petrel 2014 version) used for analysis, the result analyzed after various cross plots comparing the amplitudes with well logs reveals several trends were discovered, this indicates that higher amplitudes correspond to higher concentrations of hydrocarbons or water based on peak amplitude versus neutron log cross-plot for well KR-1. This study examines the relationship between well logs and amplitude peaks with troughs, as well as potential changes in log signal resulting from variations in seismic amplitude when assessing reservoir sand.
