Jurassic discoveries in Kuwait during recent years have met with potential successes and are among the landmark achievements in its exploration history. In this list, the success in Bahrah area of North Kuwait attracts special significance for its light oil production from fracture dependent permeability/porosity from an otherwise low matrix porosity carbonate reservoir. Middle Marrat and Najmah Formation within the Jurassic are main recognized reservoirs with proven hydrocarbon in Kuwait. The well evidence in and around the area suggests that Middle Marrat Formation in Bahrah area is of mud prone facies in an outer mid ramp to outer ramp setting having low matrix porosity. Therefore, hydrocarbon potential and productivity of Jurassic reservoir dominantly depends upon open fracture net work connectivity. To evaluate this reservoir characteristics and favorable hydrocarbon traps, the structural style of Bahrah and their fault framework were analyzed through detail mapping of the area. The study brought out N-S elongated faults which changed dominantly to NW-SE direction towards north. This change of fault orientation impacted a rotation effect over a considerable area which is expected to develop intense fracture zone. The large Bahrah prospect is also a combination of several independent structural and fault closures associated in a compressional stress system that paved the way for good fracture development. Seismic attributes such as spectral decomposition, edge slices, and frequency related trace attributes coupled with fracture interpretation from core and image logs of the wells have led to infer these fracture corridors. The studies through geomechanical modeling, curvature maps further consolidated the possible recognition of fracture corridors in the area. Use of ant tracking to define the sub seismic scale finer faults and lineaments are identified to track fracture corridors and appropriately placing the well locations with desired deviations to penetrate through more number of fractures.
