... Voidage Replacement Ratio (VRR) can be defined as the ratio between the total fluid injection in reservoir barrels and the total fluid production in reservoir barrels. VRR is used as a key indicator to achieve the required reservoir pressure, particularly when the wells are not equipped...

... indicators in a low permeability carbonate reservoir. The main objective of this effort is to maximize short-term oil rates and long-term recovery while honoring target constraints on voidage-replacement ratio (VRR), reservoir pressure, sweep efficiencies, and production and injection rates. In essence, our...

... was used to monitor voidage replacement ratio (VRR) to provide a basis for pattern balancing. A very extensive surveillance operation provides the data necessary to monitor individual pattern balance and watercut performance, optimize areal sweep efficiency by adjusting injection and production allowables...
