Dynamic Data and Flowing Material Balance Method to Unlock Potential in New Game Reservoir with Limited and Low-Resolution Data

Abstract

A new production zone CD carbonate was discovered in the Sidayu field by exploration well S3ST. Post drill static evaluation shows the production zone has limited connected volume and low reservoir quality. However, converted S-3ST has excellent production performance. The differences between prognosis and actual production performance is the reason to re-evaluate the reservoir. New approach using dynamic data was proposed to re-estimate hydrocarbon in-place and reservoir properties. This approach is no needed for well interference activities that may take a long time, if reservoir permeability is low enough which will affect the economic value of the well, by combining rate and flowing pressure during production with no well downtime.
