“…Traditionally, faults and fractures are interpreted as discontinuities in seismic amplitude data Gersztenkorn and Marfurt (1999). The automated fracture detection flow used by Tomaso et al (2013) and adapted by Bulhões et al (2019), represented in Figure 6, has signal processing technology and interactive tools to decrease interpretation time compared to fully manual methods. The flow input is a volume of discontinuity or similarity extracted from the amplitude, and the output is a volume of the relative probability of faults and fractures.…”

“…Vector Azimuth is the main product of this workflow. It is an attribute that represents fault and fracture's directions extracted in each slice from the preconditioned coherence attribute (Tomaso et al, 2013) and helps to determine the azimuths of fracture families. It contributes to the structural definition and consequently the understanding of orientation, geometry and fault network.…”

Vertical seismic profile (VSP) data is generally considered to be underutilized. Traditionally, VSP data is acquired to determine direct time-depth relationships and produce sections and images. Faults and fractures may be important to improve reservoirs exploitation as well as to monitor mechanical and hydraulic impact on reservoir rocks. This work presents a case study applied to an offshore seismic survey in the Campos Basin. A multioffset VSP data set is used as input in an automated fault and fracture detection workflow usually applied to conventional seismic data using coherence attributes. The automatic extraction of faults and fractures uses signal processing and interactive tools to reduce interpretation time compared to fully manual methods. Workflow's input is a volume of discontinuity or similarity extracted from VSP's amplitude, and the output is a volume of fault azimuths. In work carried out, the directions of faults and fractures detected from this workflow showed great correlation when compared to the interpretations in the wells. The attributes proved to be quite effective in improving the visualization of faults and fractures.

The introduction reviews topics relevant to the fundamental controls on fluid flow in carbonate reservoirs and to the prediction of reservoir performance. The review provides research and industry contexts for papers in this volume only. A discussion of global context and frameworks emphasizes the value yet to be captured from compare and contrast studies. Multidisciplinary efforts highlight the importance of greater integration of sedimentology, diagenesis and structural geology. Developments in analytical and experimental methods, stimulated by advances in the materials sciences, support new insights into fundamental (pore-scale) processes in carbonate rocks. Subsurface imaging methods relevant to the delineation of heterogeneities in carbonates highlight techniques that serve to decrease the gap between seismically resolvable features and well-scale measurements. Methods to fuse geological information across scales are advancing through multiscale integration and proxies. A surge in computational power over the last two decades has been accompanied by developments in computational methods and algorithms. Developments related to visualization and data interaction support stronger geoscience-engineering collaborations. High-resolution and real-time monitoring of the subsurface are driving novel sensing capabilities and growing interest in data mining and analytics. Together, these offer an exciting opportunity to learn more about the fundamental fluid-flow processes in carbonate reservoirs at the interwell scale.
