Seismic interpretation :

Seismic-to-well tie, Horizon interpretation, Velocity modelling, Depth conversion, and DHI analysis and interpretation. Structural and isochron/isopach map creation in time and depth, amplitude/attribute-extraction map creation with structural contours. Seismic attribute analysis (volume-, and horizon-based) and advanced seismic visualization using voxel opacity techniques.

Seismic stratigraphy :

We carry our integrated seismic stratigraphic studies using latest developments in seismic interpretation and visualization technologies. We start with the play concept definition followed by seismic sequence analysis. We then apply advanced seismic facies analysis starting with analog model building by comparison with ancient system analogs from outcrops and modern system analogs from sea floor. We then carry out unsupervised and supervised neural network-based seismic facies classification and geobody detection. We also apply seismic morphologic studies on the basin, field, and reservoir scale as part of the workflow. We integrate results with available geological data to construct local chronostratigraphic chart of studied area and predict changes in rock body distribution in time and space.

Attribute Analysis :

We apply seismic multi-attribute studies either independently or as part of an integrated seismic reservoir characterization study depending on the project scale and goals. We prefer applying multi-attribute analysis after a detailed seismic stratigraphic analysis for more reliable results. We integrate results with Acoustic Impedance (AI) and Elastic Impedance (EI) results of available. We then use results to create litho-petrophysical quantitative volumes and maps as well as seismic facies maps that can be used in an integrated sedimentological model building.

Inversion :

We guarantee best possible results out of your available data after applying detailed QC on all the inversion steps. We involve our client in all inversion stages upon his request. For further accuracy, we carry out peer review by multi-discipline team so that the results can be easily incorporated with your other work. Interactive updates of the results can be done as new well data become available.

Reservoir characterisation :

We use an integrated approach to integrate multiple data sets, obtained from different methods, such as laboratory, well logging, seismic and production history, in addition to geological information, for building a 3D facies, permeability, porosity and saturation static model. In many cases, especially if there is a lack of enough well data, we use a seismic-conditioned model approach. In this case, we use Gassman model to unravel the relationship between petrophysical parameters and data (well logs and seismic amplitudes). Using impedance well data (Ip = Vp*Rho) and Impedance seismic trace, at well location, petrophysical calibration parameters model is performed, after fluids substitution studies. This approach results in high-confidence morel that is obtained from integrating well and seismic data.
