Productivity of fractured gas-condensate wells: A case study of the Smorbukk field
This paper describes a systematic study of the effect of condensate blockage on the productivity index (PI) of hydraulically fractured wells in a complex, highly heterogeneous reservoir containing rich gas condensate, The study was performed for the Smorbukk field offshore Norway with sophisticated simulation models. The techniques used are general, and the study findings apply as guidelines in general to fractured gas-condensate wells. Proppant fracturing is capable of restoring most of the productivity lost owing to liquid buildup. The effectiveness depends primarily on the reservoir heterogeneity, fracture length and conductivity. The relative benefits of fracturing decrease in highly heterogeneous formations.
