... Carbonate reservoirs are often characterized by karst features occurrence, usually related to a significant permeability enhancement in presence of low porosity and low permeability matrix type sediments. The distribution of such karst features is generally highly heterogeneous and difficult...

... features such as collapsed-cave complexes, conduits and infiltration or dissolution zones. A multivariate attribute classification technique is applied to generate karst seismic facies that highlight these features. Clustered karst features are sampled into the grid model to construct a 3D architecture...

... Abstract In the Minagish field, the Shuaiba formation has very low porosity and permeability, However, the presence of shrinkage cracks, joints and fractures make it ideal disposal zones. Karsts feature south east of the Minagish structure, containing an abundance of fractures and dissolution...

... study that kicked off in 2007, a 2006 repeat 3D seismic swath study gave information on the 2006 Gas Water Contact. Good quality 3D seismic attribute data enabled identification of karst features that were incorporated in reservoir modelling. This, together with the good reservoir surveillance data...

... of prestack bandwidth and signal-to-noise ratio was required. The focus of this paper is the improvement of imaging and prediction of karst features, such as sinkholes, in Shuaiba formation. This is one unforeseen result obtained during the project-integrated workflow between the contractor and the MRH...
