Paper Number: SPE-197099-MS
...-permeability streaks, permeability contrast in layered reservoirs, vugs, and natural fractures are all examples of geological character that preclude good performance in conventional gas injection EOR. A common aphorism in conventional gas injection was that the only gas that has any benefit was the gas...

Paper Number: SPE-197094-MS
... Obtaining the properties and geometry of fractures is the main problem in fractured reservoirs’ history matching. Infill drilling becomes necessary as unconventional reservoirs are further developed. However, the geometry of hydraulic fractures can be very complex which makes it very difficult...

Paper Number: SPE-197107-MS
... Abstract Reservoir pressure and stress behaviors are simulated during elapsed time between sequential fractures in multistage and multipad hydraulic fracturing scenarios to analyze interference between fractures and to manage potential fracture given interactions. Commonly current implemented...
