Provenance (geology) drainage capture analysis)can provide valuable insights to all stages of hydrocarbon exploration and production. In exploration stage, provenance studies can enhance the understanding of reservoir distribution and reservoir quality. These will affect chance of success of exploration project; In development stage, mineralogical and chemical techniques are widely used to estimate reservoir zonation and correlation of stratigraphy. At the same time, these provenance techniques are also used in production stage. For example, they are used to assess permeability variations and well decline rate resulting from spatial variability in diagenesis and depositional facies Provenance (geology) Provenance in geology, is the reconstruction of
