Polymer flooding plays an essential role in Enhanced Oil Recovery by means of achieving a more favorable mobility ratio through increasing the viscosity of the displacing phase and thus improve macroscopic sweep efficiency. Conventional polymer, e.g., hydrolyzed polyacrylamide, dissolved in brine at high-salinity and high-temperature can be...

The current situation with green gas emission requires the development of low carbon energy solutions. However, a significant part of the modern energy industry still relies on fossil fuels. To combine these two contradictory targets, we investigate a strategy based on a combination of CO2 sequestration with Enhanced Oil Recovery (EOR) in the...

In the past decades, several EOR (Enhanced Oil Recovery) techniques have been developed to increase the amount of oil recoverable from a reservoir. Among these techniques, polymer flooding consists in the injection of a solution of water and polymer into the reservoir, and it is performed in order to lower the mobility of injected water. A...

The Dutch Government is aiming for a CO2 neutral energy supply in 2050; this requires a transition from using energy from fossil fuels to using renewable energy sources. Decline in oil production in the Netherlands occurs in an epoch with an increased interest in geothermal heat production as an alternative source of energy. In the present study...

Since the 1950s, numerical models are widely used in reservoir simulators to predict and optimize oil recovery from petroleum reservoirs. Commercial simulators typically combine multiphase porous media flow models with a separate module for the transport of tracers. By decoupling flow and transport, the transport equation can be solved using a...

Non-Newtonian foam flow in a reservoir can be modeled numerically by discretization of the corresponding analytical formulas. The injection of foam is compared to the injection of water by comparing the injection pressures, which is represented as a dimensionless pressure rise at the injection well. The model first applies the forward-difference...

The partitioning inter-well tracer test (PITT) is a method to determine average oil saturation between an injector-producer pair. Tracer tests can be used to quantify incremental oil recovery in enhanced oil recovery (EOR) pilots and for reservoir surveillance purposes. This study provides a sensitivity analysis of the inter-well tracer test,...

Oil is one of the major contributors to energy consumption. Oil reserves are expressed as the total amount of economically and technically producible oil. Total oil consumption is increasing (per capita it remains more or less the same) but it has no unambiguous influence on the remaining reserves due to new discoveries. However, increasingly...

The formation of microemulsions of an EOR surfactant with n-decane was studied in a microfluidic setup using fluorescence microscopy. Generally microemulsions are studied under static conditions by means of phase behavior tests. However, oil mobilization fromreservoirs is a dynamic process and therefore it is important to understand how...

Characterization of fluid properties is significant in the petroleum engineering practice, especially in solvent-based enhanced oil recovery (SEOR) where the use of injected chemicals should ideally be reduced to the bare minimum in order to minimize the costs and environmental impact of SEOR. However, current techniques for measurement inside...

Enhance Oil Recovery (EOR) techniques are theoretically very promising but in real life suffer the effects of many physical complications in the subsurface which are yet to be understood in detail. One such complication is the detrimental effect of oil in foam in foam EOR. Current-generation reservoir simulators represent these effects in an...

Enhanced oil recovery by gas injection can show excellent displacement efficiency but may suffer from poor sweep efficiency. A promising method to overcome poor sweep efficiency in gas-injection enhanced oil recovery processes is foam injection. The effect of oil saturation on foam stability is complicated and not fully understood. Complexity in...

Foam is a promising means of increasing sweep efficiency in enhanced oil recovery processes where gas is injected into a reservoir. However, the effectiveness of foam is hard to predict due to its complex behavior. Therefore accurate modeling is important to effectively predict field performance. This requires correct foam parameters in...

In gas-injection enhanced oil recovery (EOR), foam is a promising method to improve sweep. We studied foam for EOR through analytical modeling and simulations in two cases: the ability of foam to prevent gravity override over large distances and the effect of oil on foam processes. Shan and Rossen (2004) present a simple model for SAG ...

A screening study and subsequent dynamic simulation of selected Enhanced Oil Recovery (EOR) methods for the Rijn oil field are presented. The objective of the study was to obtain insight in the EOR potential of the Rijn field. The Rijn oil field, located in block P15 in the Dutch sector of the North Sea Continental Shelf, produced 24MMSTB oil...
