... and reservoir screening criteria, as well as ratios for nitrogen demand and incremental oil production. Nitrogen is produced from air, and therefore universally available as an inert and low cost injection fluid. The technology can be used in onshore and offshore environments, and especially in areas where...

Paper Number: SPE-175749-MS
... Abstract Tight gas reservoir development has long been affected by 1) complex flow profiles and 2) the impact of very low permeability on reservoir productivity. Where well tests (WT) buildup is very short, interpretation becomes difficult and results often are ambiguous. Most WT of tight, dry...

... The producing reservoirs include several sandtone layers of lower Triassic and lower Devonian (Emsian) ages. BRN field is mostly developed in the Devonian formations, generally subdivided in four main different levels (B, C, G and T). On the other side, BSF wells are perforated only in Triassic...
