Abstract

Summary

4D seismic is now a standard tool to monitor the wells production effects within the reservoir and to identify operational opportunities to maximize the recovery. The main goal of this paper is to show the added value of 4D seismic monitoring to check and ensure integrity of the overburden 4D signal induced by reservoirs production. The 4D seismic processing of the data is of paramount importance to preserve the actual 4D effects in the overburden and having overburden-dedicated workflows is mandatory to preserve those effects. Considering field geology, interpretation knowledge and performing advanced 4D Quality Controls (QCs) are critical elements that we propose to use in our global QC strategy to drive the efforts in processing. The efficiency of the proposed methodology is illustrated through two case studies in clastic environments where 4D seismic was key to detect signals in the overburden.
