Overview

What is he best known for?

The fields of study he is best known for:

  • Organic chemistry
  • Carbon dioxide
  • Ion

His primary areas of study are Mineralogy, Wetting, Carbonate, Seawater and Enhanced oil recovery. His Mineralogy research focuses on Oil field and how it connects with Dolomite, Calcite and Displacement. In his research on the topic of Wetting, Inorganic chemistry and Artificial seawater is strongly related with Sulfate.

His Carbonate research is multidisciplinary, incorporating perspectives in Petroleum reservoir, Water injection, Aqueous solution and Oil in place. His studies deal with areas such as Clay minerals and Adsorption as well as Enhanced oil recovery. His Clay minerals research includes elements of Desorption and Environmental chemistry.

His most cited work include:

  • Wettability alteration and improved oil recovery by spontaneous imbibition of seawater into chalk: Impact of the potential determining ions Ca2+, Mg2+, and SO42− (473 citations)
  • Wettability alteration in chalk 2. Mechanism for wettability alteration from oil-wet to water-wet using surfactants (386 citations)
  • Smart Water as Wettability Modifier in Carbonate and Sandstone: A Discussion of Similarities/Differences in the Chemical Mechanisms (345 citations)

What are the main themes of his work throughout his whole career to date?

Tor Austad focuses on Wetting, Mineralogy, Seawater, Carbonate and Enhanced oil recovery. The various areas that Tor Austad examines in his Wetting study include Petroleum reservoir, Acid value, Adsorption and Pulmonary surfactant. His Mineralogy research is multidisciplinary, relying on both Water injection, Salinity, Outcrop, Oil field and Dissolution.

The concepts of his Seawater study are interwoven with issues in Geotechnical engineering, Submarine pipeline, Compaction, Geochemistry and Produced water. He has researched Carbonate in several fields, including Porosity, Sulfate, Calcite and Petroleum engineering. His Enhanced oil recovery study incorporates themes from Environmental chemistry, Chemical reaction, Petrology and Oil in place.
