Abstract

A workflow is applied for properties modelling integrating petrophysics, rock physics and log facies with seismic. Geological modelling is integrating seismic probabilities generated using a Probabilistic Petrophysical Inversion or a conventional facies classification and properties calibration of seismic elastic attributes. Different scenarios are generated exploring the geostatistical variability of properties or/and sampling seismic probability of petrophysical properties. From hundreds of realizations, reference cases are selected for dynamic model, risk analysis, development strategy. As an alternative, a second static model sharing the same structural framework, but different facies and geostatistical procedure, is used to assess the impact of different geology on the reference development scheme. Horizontal wells are drilled to exploit the reservoir of deep water fields; the quick update of the seismic driven model has to include these challenging data. Reservoir mapping from ultra-deep azimuthal electromagnetic technology is integrated to update the structural model and depth calibrate the seismic attributes. If a new well confirms model predictions, the simulation is updated by aggregating new data to the initial log models, without a new seismic inversion. The updated model is used to optimize final location of new wells. When production starts, the geological scale model is validated for proper reservoir management.
