The Application of Seismic Machine Learning (SML) for Improving and De-Risking Well Placement in Carbonate Reservoir: A Successful Study on the Mapping of Karst Distribution, AA Field, Northeast Java Basin, Indonesia
Well placement in tight carbonate reservoir with targeting thin karst is very challenging, especially to locate and map karst distribution and to identify the good spot. The nature of heterogeneous carbonate reservoir and limitation of seismic resolution are the subjects to be understood and resolved prior to further interpretation.
Seismic ML is a robust method and fast to generate new insight of seismic resolution for interpretation, maximizing and extracting tens of seismic attributes to be used simaultaneously in predicting and determining porous zones which are associated with karst.
Seimic ML has been tested in AA field with the objective to optimize well placement into sweet spots associated with porous karst. The results show that ML has capability to predict the porous zone target which is reflected by losses zone during drilling operation of development well AAD-1.
