Modelling Mineral-Scaling in Geothermal Reservoirs Using Both a Local Equilibrium and a Kinetics Approach

An engineering approach to study the effect of saturation-dependent capillary diffusion on radial Buckley-Leverett flow

1D water oil displacement in porous media is usually described by the Buckley-Leverett equation or the Rapoport-Leas equation when capillary diffusion is included. The rectilinear geometry is not representative for near well oil displacement problems. It is therefore of interest to describe the radially symmetric Buckley-Leverett or Rapoport...

Fall-off test analysis and transient pressure behavior in foam flooding

Gas injection projects often suffer from poor volumetric sweep because under reservoir conditions the density and viscosity differences between the gas and the in-situ oil leads to override and bypassing of much of the oil in place. Foam has been suggested as a potential solution to this shortcoming and has shown success in some of the field...

Recovery of light oil by air injection

In this paper we review the results of analytical, numerical and experimental studies related to air injection into porous medium containing initially light oil, water and gas at medium pressure conditions. The new combustion mechanism is described, where the process of the medium temperature oxidation interacts with the oil vaporization...

Combustion for Enhanced Recovery of Light Oil at Medium Pressures

Using conventional production methods, recovery percentages from oil reservoirs range from 5% for difficult oil to 50% for light oil in highly permeable homogeneous reservoirs. To increase the oil recovery factor, enhanced oil recovery (EOR) methods are used. We distinguish EOR that uses chemical methods, (partially) miscible methods and thermal...

Modeling of in-situ combustion as thermal recovery method for heavy (medium) oil (poster)

In-situ combustion (ISC), as a well known process for secondary and tertiary oil recovery, is an important alternative approach to achieve higher production efficiency for light and heavy oil reservoirs. The in-situ combustion process is a complex combination of a number of processes which occur in different temperature ranges. As a consequence...
