Automated Fracture Analysis in Middle Triassic Muschelkalk, Upper Rhine Graben

Merz, Lena; Manss, Yasar; Hilgers, Chirstoph

Abstract (englisch):
Fractured Muschelkalk carbonates are an E&P target in the Upper Rhine Graben. However, fracture spacing, age relationship and reservoir relevance are hard to establish from subsurface data. Since the Muschelkalk carbonates are well exposed on the graben shoulders, we apply our new field methods and -workflows in an open pit mine close to Karlsruhe. Our aim is to establish the history of fracture networks from vertical quarry walls and subhorizontal floors to build a discrete fracture network model to further improve 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, our UAVs image the quarry floors, which enables to derive the relative age relationship and lateral continuity of fractures. Based on quarry data, we build a discrete static 3D fracture network, integrated in state of the art software tools such as FracMan, FracaFlow and Petrel.

The Knittlingen outcrop comprises of 85- 100m of Upper Muschelkalk with continuous dm-thick carbonate beds and intercalated mm-thick black shales. ... mehr
