Life of Field Seismic at Ekofisk - Utilizing 4D Seismic for Evaluating Well Target

Four Ekofisk LoFS surveys have been acquired and processed to date. The improved repeatability and detectability of 4D seismic signals from the LoFS surveys have provided additional information that is being used for reservoir monitoring and characterization. This paper demonstrates an example of the use of the Ekofisk LoFS data for confirming the selected location of a new development well and improving our understanding of the risk of water swept section along the well trajectory.
