In this paper we present a new code to build geologically realistic models of natural fracture networks in geological formations, by simulating the processes of fracture nucleation, growth and interaction, based on geomechanical principles and the ge

Large scale modelling of fractured reservoirs is a persistent problem in representing fluid flow in the subsurface. Considering a geothermal energy prospect beneath the Drenthe Aa area, we demonstrate application of a recently developed approach to e

In this chapter, we examine the interactions between fractures. We examine three types of fracture interaction: microfractures which become enveloped by the stress shadows of propagating macrofractures; macrofractures which propagate into the stress

In this chapter, we summarise the key insights we gain from the new method and discuss its potential applications in geomechanical and fluid flow modelling. We consider the value that it could add in various industrial contexts, including tunnel exca

Summary We apply the mechanically driven approach to fracture modelling of Welch et al. (2019) to two fractured outcrops, Nash Point in South Wales and Robin Hood’s Bay in NE England. We show that the local stress field developed around larger faul

In this chapter, we derive equations to describe the growth of layer-bound macrofractures in response to an applied horizontal strain. These form when microfractures grow large enough to span the entire layer, so we can calculate the rate of macrofra

In this chapter, we examine the impact of the growing fracture populations on the in situ stress in the fractured layer. We describe two potential scenarios. The first is the stress shadow scenario, in which displacement on a fracture accommodates al

In this chapter, we use observations from three fractured outcrops in the UK (Nash Point, Robin Hood’s Bay and Pegwell Bay) to generate discrete fracture network models (DFNs). We show that these DFNs can replicate the complexity observed in the re

In this chapter, we apply our method to two subsurface examples: the Kraka oilfield in the Danish North Sea and an onshore geothermal prospect in the Drenthe province in the Netherlands. Production from the Kraka field is highly dependent on the natu

Deep water fold and thrust belts (DWFTBs) are sedimentary wedges that accommodate plate-scale deformation on both active and passive continental margins. Internally, these wedges consist of individual structures that strongly influence sediment dispe
