The integration of all available information is a key point to improve the description of a reservoir . In particular, seismic data are essential to complete our knowledge of the reservoir between the wells. We illustrate this point through an integrated procedure applied to a gas storage reservoir. This procedure combines different techniques using post-stack seismic data, impedance well logs and geological information. It is divided in three mais steps 1. waveform calibration of the stacked seismic data using wen log-baserf reflectivity 2. generation of inter-well impedances using stratigraphic modelling and inversion 3 . inter-well impedance facies recognition using multivariate statistical techniques and geological interpretation .
