Application of 3D outcrop data in reservoir geology on the examples of fractured carbonates in the Upper Rhine Graben

Merz, Lena; Baier, Uwe; Hilgers, Christoph

Abstract (englisch):
3D field applications have a high potential to gain large amounts of data in a relatively fast time from former inaccessible reservoir analog outcrops. We apply terrestrial laser scanning (t-LiDAR) and UAV-based Structure from Motion (SfM) on fractured Muschelkalk outcrops on the graben shoulder of the Upper Rhine Graben. Upper Muschelkalk carbonates are an important E&P target in the Upper Rhine Graben, but reservoir characterization from 1D subsurface data is insufficient for a broad understanding of fracture networks in the tight carbonates. Therefore, we work in well exposed open pit mines with the aim to unravel fracture spacing, orientation and history and help improve reservoir exploration and production.

Our terrestrial laser scanner (Lidar) derives the fracture orientation and spacing from steep inaccessible vertical quarry walls with an in-house developed workflow. Additionally, quarry floors can be imaged by our UAVs, resulting in high resolution orthophotos from which we derive relative age relationships and lateral continuity of fractures. Based on quarry data, we build a discrete static 3D fracture network and are able to simulate fluid flow with state of the art software tools such as FracMan, FracaFlow and Petrel.
