“…Early and pervasive cementation of the carbonate platform causes embrittlement, leading to the development of major syn-depositional fracture systems behind the margin of steepsided platforms (Hunt et al 2003, Frost and Kerans 2010, Nolting et al 2020. This can have important consequences for production, for example in the Paleozoic super-giant Tengiz field in Kazakhstan (Narr and Flodin 2012), and the Devonian-aged Kharyaga field in Russia, (Spina et al 2015).…”

The characterisation of fractured reservoirs and fractured geothermal resources requires a thorough understanding of the geological processes that are involved during fracturing and the host rock rheological properties. The presence or absence of mechanical layering within the rock and the mode of failure substantially control the organization and scaling of the fracture system; subsequent chemical alteration and mineralization can both increase or decrease porosity and permeability. An integration of this understanding using information from outcrop analogues, together with static and dynamic subsurface data,can improve our ability to predict the behaviour of fractured reservoirs across a range of scales.Thematic collection: This article is part of the The Geology of Fractured Reservoirs collection available at: https://www.lyellcollection.org/cc/the-geology-of-fractured-reservoirs

“…Carbonate rocks are the results of interacting biological, geological and physico-chemical processes, often over a long period of time. Stratigraphic forward modeling has been demonstrated to be a powerful tool to quantify the controlling parameters (sea level, subsidence, carbonate production, transport…) on siliciclastic and carbonate system architectures and to challenge fundamental concepts of stratigraphy (Burgess et al, 2006;Warrlich et al, 2008;Montaggioni et al, 2015;Spina et al, 2015). There is room for methodologic improvement in exploration of carbonate prospects, particularly by better integrating naturalistic and quantitative approaches.…”

Testing geologic assumptions and scenarios in carbonate exploration: Insights from integrated stratigraphic, diagenetic, and seismic forward modeling

Carbonates are considered complex, heterogeneous at all scales, and unfortunately often poorly seismically imaged. We propose a methodology based on forward-modeling approaches to test the validity of common exploration assumptions (e.g., chronostratigraphic value of seismic reflectors) and of geologic interpretations (e.g., stratigraphic correlations and depositional and diagenetic architecture) that are determined from a limited amount of data. The proposed workflow includes four main steps: (1) identification and quantification of the primary controls on carbonate deposition and the prediction of the carbonate stratigraphic architecture (through stratigraphic forward modeling); (2) identification of diagenetic processes and prediction of the spatial distribution of diagenetic products (diagenetic forward modeling); (3) quantification of the impact of diagenesis on acoustic and reservoir properties; and (4) computation of synthetic seismic models based on various scenarios of stratigraphic and diagenetic architectures and comparison with actual seismic. The likelihood of a given scenario is tested by quantifying the misfit between the modeled versus the real seismic. This workflow illustrates the relevance of forward-modeling approaches for building realistic models that can be shared by the various disciplines of carbonate exploration (sedimentology, stratigraphy, diagenesis, seismic, geomodeling, and reservoir).
