Seismic data interpretation of the Snøhvit gas field - .
In this work, 3D seismic and well data are used for mapping the Snøhvit reservoir and modelling the hydrocarbon column through Petrel software. The reservoir mapping procedure consisted in interpreting horizons, faults and other relevant features. This mapping and modelling process have been done af...

In this work, 3D seismic and well data are used for mapping the Snøhvit reservoir and modelling the hydrocarbon column through Petrel software. The reservoir mapping procedure consisted in interpreting horizons, faults and other relevant features. This mapping and modelling process have been done after exporting and calibrating the data. The data calibration consisted of tying seismic to well data. This had been done using check shots (well data) to produce a Time Depth Relationship (TDR) and, thereafter, mimic the seismic data at well location, i.e. produce a synthetic seismogram for the 7121_6_1, 7121_4_1 and 7121_5_1 wells all, inside the cube.
