Upstream petroleum
Refining geostatistical models in order to better take into account and decrease uncertainties.
Interest in new geostatistical technologies has constantly been increasing during recent years in the upstream petroleum field. By proposing solutions based on M-GS, a high precision geostatistical technology, ESTIMAGES sets its development in that of a sector concerned about the quality of its models.
GEOSTATISTICAL SOLUTIONS
GEOPHYSICS
Quality control and seismic velocities filtering
Evaluation of the amount of artefacts into a velocity field.
Optimal filtering of velocities for time-to-depth conversion, angle studies, overpressure analysis, Dix velocities computation, etc.

| Raw data | Amount of artefacts | Anomalies reporting |
Footprint removal, filtering of non-stationary random, horizontal noises, etc. with optimal preservation of the signal through the consideration of the data’s local structural characteristics (M-GS technology).

M-GS TECHNOLOGY
Porosity simulation driven by a geobody (euclidian grid)
Since it allows to take into account the structural non-stationarity of a data set, M-GS applied to the field of petroleum studies enables to obtain better quality geostatistical analysis and processing than those obtained using a conventional geostatistical approach.
