Abstract

Despite the perceived challenges, 4D technology has added value in development of the hard carbonate reservoirs in Campos basin. However, extracting such value from 4D seismic data in Field-X was not a trivial task. Very poor repeatability in this field cast doubt on the 4D interpretation driven solely by seismic data analysis. To maximise the added value of the time-lapse data in development of the field and constraining the simulation model, we followed the tiered approach proposed by Amini & MacBeth (2018). Here, several tools were used to assess the reservoir connectivity based on the production data. The 4D seismic response was also examined through modelling and inversion exercises. Assimilation of the production data and the refined 4D attributes enabled us to design a metric to assign a confidence flag to each of the 4D anomalies. This increased the value of information derived from a noisy dataset, as well as the confidence level towards its interpretability.
