This approach has clear advantages due to early access, low cost, and a continuous reservoir fluid GOR for all reservoir zones. In this paper, we release further study results to predict other fluid properties besides GOR, which...

The five important attributes of the methodology presented are: Consistency: To ensure a fair comparison is made when evaluating each lift technique, the same assumptions about reservoir performance, fluid properties, multi-phase flow behaviour, geomechanics etc. are used. Auditability...
