Abstract

Summary

Within one year of production startup, the small 2016 Viper-Kobra oilfield development offshore Norway, was proven successful by draining more than the predrill P50 reserves. The reservoir consists of remobilized and injected sands from the Paleocene Hermod formation. As the sands are remobilized and injected into hydraulic fractures, the depositional fabric of the sands are lost and the reservoir properties enhanced. The development took advantage of the good permeability and reservoir connectivity of the injected sand environment in Viper-Kobra by placing trajectories in thin sands, sacrificing wellbore NTG for vertical and lateral distance to water. Further reserves were added by including a shallower lateral to exploit unpredicted and sub seismic dykes discovered during the development drilling.
