Faults and fractures corridors in the Natih carbonates of Jabal Madmar 

Located in the Salakh Arch, in the foothills of the Oman Mountain, the Jabal Madmar anticline is a widely recognised field-scale fractured carbonate reservoir analogue. Due to exceptional outcropping conditions, it offers rather unique opportunities to observe the natural fracture system occurring in the Cenomanian Natih carbonates. The analogy between Jabal Madmar and some of the largest North Oman Natih subsurface reservoirs is enhanced by strong similarities in terms of rock depositional environments and by comparable structural evolutions. The sector selected for this field trip is located to the South of the structure, where the intensely deformed flank of the fold is exposed. It exhibits a spectacular fracture pattern which can be observed in 2D and 3D from the scale of bed-constrained opening-mode fractures (“background fractures”) up to fracture corridors and sub-seismic scale fault zones. The Natih carbonate section also includes vertical lithological and rheological contrasts. This enables to set-up a clear mechanical stratigraphy framework across the stratigraphic column and to observe how this framework controls the respective occurrence, propagation and distribution of the various fault and fracture types. 

The field trip will involve a relatively long drive from Muscat to the city of Adam (3h30, approximate duration). During this travel the field trip attendees will be able to observe a succession of landscapes ranging from the world-famous Sumail ophiolite units to the collision belt of the Oman Mountains and to the desertic areas of the country Interior. An effort will be made on the outcrops to replace the local observations within the larger-scale context of the regional geology.

Loïc Bazalgette (PDO) 

Loïc holds a structural geology PhD from the University of Montpellier (Southern France), during which he studied the kinematic and mechanical interactions between folding and fracturing processes in sedimentary rocks. He joined Shell International Exploration and Production in the Netherlands in 2006, where he worked for 7 years supporting the characterization and modelling of fractured reservoirs worldwide. Since January 2013, he works as a Senior Structural Geologist in Petroleum Development Oman (PDO). His principal activities in PDO include the characterization and/or the re-evaluation of the fractured carbonate fields in North Oman. He also contributes to the structural analysis and tectonic framing of PDO’s hydrocarbon portfolio. In parallel with these activities, Loïc is heavily involved in technical coaching and teaching.

Pascal Richard (Shell)

Pascal Richard holds a structural geology PhD from the University of Rennes (France), during which he studied the development of strike-slip fault zones. He joined Shell International Exploration and Production in the Netherlands in 1991, where he initially worked for 5 years in the structural geology research department, with a special focus on the formation of faults in a wide variety of structural styles using sandbox analogues. Pascal has then worked alternatively from the Netherlands and Oman, with a strong focus on the Middle East since 1996.
Currently, Pascal is structural geology subject matter expert in Shell Global Solutions International B.V. He has been working both at exploration and production scales in a variety of structural settings and locations. Pascal is recognized within and outside Shell as a structural geology expert, as well as a global consultant on faults and fractured reservoirs in general. Beyond his consultancy activities, Pascal has an active coaching role. He develops and facilitates a range of structural geosciences courses.
