Improving Seismic Reservoir Characterization With Broadband Seismic

Abstract

Broadband acquisition and processing technology has revolutionized seismic acquisition and interpretation. The revolution is not complete however, as we continue to explore how broadband can affect our efforts towards reservoir characterization. In particular, we see the ultimate benefits for reservoir properties with unprecedented bandwidth and accuracy through simultaneous AVO inversion. When performing inversion on broadband seismic data there are some particular properties that need to be considered in different steps of the process. Additionally, careful thought has to be given on how to use inversion QC's to indicate the value of broadband seismic in the inversion stage. We will show some results from our initial experiences in this area.

Integration of broadband seismic data into reservoir characterization workflows: A case study from the Campos Basin, Brazil

“…As for any type of seismic data, a fundamental principle remains true for broadband data: Reservoir characterization will only fully benefit from the seismic data if it is properly processed and imaged. This is achieved through new methods and algorithms that are better suited to the wider bandwidth, and, in particular, the low-frequency content of the data (Mesdag and Schakel, 2015;Soubaras, 2016) as well as the judicious choice of processing parameters coupled with quality control (QC) that makes it possible to assess signal preservation versus noise attenuation (Coleou et al, 2013). In this work, we propose to revisit some of the main steps in the seismic signal treatment and seismic inversion of broadband seismic data, using the Campos Basin variable-depth streamer seismic data set.…”
