Abstract
The company NOVATEK performed in 2008–2010 the 3D seismic works within the aquatorial part of the gas condensate field.
The main geological tasks were the detailed exploration and forecast for the Cretaceous deposits’ reservoir properties.
To engage in development the new prospective targets in the underlying intervals, there was a 3D survey performed in 2017
Based on the results of the work, 2 sets of data were obtained for the same area within a time difference of 7–8 years, which provided the opportunities for estimating 4D effects of the tanks being in service all these years.
The report presents the results of modeling and analysis of the real 4D effects, characterizing the processes of development and operation, as well as pointing to the reserves of improvement of the efficiency of these processes.
