“…17). No significant difference in the distribution is 306 apparent between the fault rock Vclay content when calculated using either SGR (Yielding, 2002) or ESGR 307 (Freeman et al, 2010), with a weighting factor of 1.5, as a fault rock Vclay prediction algorithm. A more 308 detailed analysis of the Vclay distribution on the fault plane reveals that the ESGR algorithm predicts a 309 more discrete distribution of Vclay, compared to the SGR algorithm (Fig.…”

Faults play an important role in reservoir compartmentalization and can have a significant impact on recoverable volumes. A recent petroleum discovery in the Norwegian offshore sector, with an Upper Jurassic reservoir, is currently in the development planning phase. The reservoir is divided into several compartments by syndepositional faults that have not been reactivated and do not offset the petroleum-bearing sandstones completely. A comprehensive fault analysis has been conducted from core to seismic scale to assess the likely influence of faults on the production performance and recoverable volumes. The permeability of the small-scale faults from the core were analysed at high confining pressures using formation-compatible brines. These permeability measurements provide important calibration points for the fault property assessment, which was used to calculate transmissibility multipliers (TM) that were incorporated into the dynamic reservoir simulation model in order to account for the impact of faults on fluid flow. Dynamic simulation results reveal a range of more than 20% for recoverable volumes, depending on the fault property case applied and for a base case producer–injector well pattern. Fault properties are one of the key parameters that influence the range of cumulative recoverable oil volumes and the recovery efficiency.

“…Shale gouge ratio (SGR) was computed along the fault plane using the thickness of the bed, average V-Shale from the hanging wall and the footwall as well as the throw distribution across the fault plane (Yielding et al, 1997;Yielding, 2002). The SGR was calculated based on Equation (10).…”

Structurally complex reservoirs form a distinct class of reservoir, in which fault arrays and fracture networks, in particular, exert an over-riding control on petroleum trapping and production behaviour. With modern exploration and production portfolios commonly held in geologically complex settings, there is an increasing technical challenge to find new prospects and to extract remaining hydrocarbons from these more structurally complex reservoirs. Improved analytical and modelling techniques will enhance our ability to locate connected hydrocarbon volumes and unswept sections of reservoir, and thus help optimize field development, production rates and ultimate recovery. This volume reviews our current understanding and ability to model the complex distribution and behaviour of fault and fracture networks, highlighting their fluid compartmentalizing effects and storage-transmissivity characteristics, and outlining approaches for predicting the dynamic fluid flow and geomechanical behaviour of structurally complex reservoirs. This introductory paper provides an overview of the research status on structurally complex reservoirs and aims to create a context for the collection of papers presented in this volume and, in doing so, an entry point for the reader into the subject. We have focused on the recent progress and outstanding issues in the areas of: (i) structural complexity and fault geometry; (ii) the detection and prediction of faults and fractures; (iii) the compartmentalizing effects of fault systems and complex siliciclastic reservoirs; and (iv) the critical controls that affect fractured reservoirs.Structurally complex reservoirs form a distinct class of reservoir in which fault arrays and fracture networks, in particular, exert an over-riding control on petroleum trapping and production behaviour
