Numerical Interpretation of Single Well Chemical Tracer Tests for ASP Injection
Authors A. H. de Zwart, D. W. van Batenburg, M. Stoll and S. Al-HarthiA series of single well ASP pilots using Single Well Chemical Tracer Tests (SWCTT) have been conducted to estimate the efficiency of Alkaline Surfactant Polymer (ASP) flooding. A SWCTT was done after water injection to establish a baseline remaining oil s

In-depth Water Diversion Using Sodium Silicate – Preparation for Single Well Field Pilot on Snorre
Authors A. Stavland, H. Jonsbråten, O. Vikane, K. Skrettingland and H. FischerThe waterflood sweep efficiency can be increased considerably by in-depth placement of a blocking agent. Sodium silicate is one of the few PLONOR chemicals applicable for water control. This paper highlights key results obtained from a research program on

Modeling of Alkali Surfactant Polymer Process by Coupling a Multi-purpose Simulator to the Chemistry Package PHREEQC
Authors R. Farajzadeh, T. Matsuura, D. van Batenburg and H. DijkAccurate modeling of an Alkali Surfactant Polymer (ASP) flood requires detailed representation of the geochemistry and, if natural acids are present, the saponification process. Geochemistry and saponification affect the propagation of the injected chemic

Molecular Dynamics Simulation of Surfactant Flooding in Asphaltenic Oils for EOR Applications
Authors E. S. Boek, M. R. Stukan and P. LigneulSurfactant flooding has recently re-emerged as a suitable method for Enhanced Oil Recovery (EOR). However, to optimize recovery rates, a better and more fundamental understanding of the recovery process is required at the pore scale. Multi-scale reservoir

Modeling Chemical EOR Processes: From Lab to Reservoir Scale
Authors F. Douarche, D. Rousseau and B. BazinChemical flooding, SP or ASP, is of increasing interest due to the need to increase oil production. Design of chemical processes is very project specific and requires case by case studies including various steps among which reservoir data analysis, chemic

Simulation of Combined Low Salinity Brine and Surfactant Flooding
Authors A. Skauge, Z. Ghorbani and M. DelshadCore flood studies have been made to investigate the effect of change in brine salinity on oil recovery from waterflood, and in particular the combination of lowered salinity and surfactant flooding. The core flood experiments used Berea core material and

Adsorption at the Calcite – Liquid Interface with Molecular Precision
Authors I. N. Stocker, K. L. Miller, S. Y. Lee, I. R. Collins, S. M. Clarke, K. J. Webb, C. J. Kinane and A. WildesWaterflooding is now recognised throughout as involving a number of coupled chemical and physical processes, whereby interactions at the surface dominate. Previously published studies have mainly concentrated on sandstone reservoir systems but a significa

A Strategy for Low Cost, Effective Surfactant Injection
Authors K. Spildo, K. Djurhuus, L. Sun and A. SkaugeIdeally, in a chemical flooding process, one would like to inject a surfactant solution that has good solubility at the relevant conditions (good injectivity), ultralow interfacial tension (efficient oil mobilization) and low loss of surfactant (better ec

An Experimental Study of Low Salinity Waterflooding and Spontaneous Imbibition
Authors S. Wickramathilaka, J. J. Howard, N. R. Morrow and J. BuckleyMany laboratory experiments and field tests have shown improved oil recovery by decrease in injected brine salinity. Spontaneous imbibition experiments provide additional insights into the mechanisms that control low salinity waterflood performance. Most

Why Such a Small Low Salinity EOR – Potential from the Snorre Formation?
Authors A. J. Reinholdtsen, A. R. RezaeiDoust, S. Strand and T. AustadTwo cores from the Lunde formation in the Snorre field have been tested at reservoir temperature for enhanced oil recovery by the low saline water injection technique. In both cases, the cores were cleaned by successive flooding with toluene, methanol, an

Low Salinity Oil Recovery – Increasing Understanding of the Underlying Mechanisms of Double Layer Expansion
Authors S. Y. Lee, K. J. Webb, I. R. Collins, A. Lager, S. M. Clarke, M. O‘Sullivan and A. F. RouthWater injection has been used to increase oil recovery since the late 19th century. For over 100 years, the mechanisms behind this incremental oil recovery have been thought as physical, i.e. the injection of water maintains reservoir pressure and sweeps
