• Linking Flowback Recovery to Completion Efficiency: Niobrara-DJ Basin Case Study

    Near wellbore complexity is a current topic of discussion among geoscience and engineering disciplines across North America. Near- and far-field wellbore diagnostic techniques are generally used for parameter constraints for rate-transient-analysis that requires months (and sometimes years) of production after post-frac flowback. In this paper presentation’s study, they utilized flowback water-oil-ratio as a diagnostic tool to provide early-time feedback for completion-efficiency evaluation.

    They analyzed flowback, post-flowback, and completion-design data of 19 multi-fractured horizontal wells completed in Niobrara and Codell formations classified into parent and child groups. Results showed that child wells had 32% more load recovery compared with the parent wells, and the parent wells showed 38% and 50% more 9-months cumulative oil production (Qo) and UQo, respectively. For both the parent and child wells, more than 50% of the predicted ultimate load recovery is produced back within the first three months of production
