Biography:

Katarzyna JarmoÅ‚owicz-Szulc (Assoc. Prof.) has been a scientific worker in Polish Geological Institute – National Research Institute in Warsaw, Poland. In her carreer she was the head of the Petrological, Mineral Deposits Departments, the Group of Rocks and Mineral Collections, the Centre of Excellence and the National Geological Archives in PGI-NRI, Poland.  She has been co-ordinating many  projects. She is an author of  over 120 papers, a reviewer and an editor. She has an experience in fields of isotope studies, fluid inclusions and hydrocarbon migration in different environments, as the Carpathians, in the marine deposits from the Baltic Sea, other hydrocarbon-bearing regions as well. 

Abstract:

As it has been postulated by Oliver (1986), when continental margins in zones of convergence are buried beneath thrust sheets, fluids expelled from the margin sediments go to the foreland basin and the continental interior. These fluids play key role in different phenomena, as e.g., faulting, migration of hydrocarbons, and mineral transportation. The North American case is a very good example of this hypothesis, relating both oil and gas fields  and their occurrences as well as e.g., lead-zinc deposits to the tectonic belts there (as the Appalachians). In Europe, the Carpathian Mountains chain is a fragment of the orogenic belt that cuts a large part of the continent. Oil and gas fields are present in the Carpathians and the Carpathian Foreland, as well as hydrocarbons are accessible at the microscopic scale – in fluid inclusions in minerals in the rocks. Hydrocarbons are very common and widespread in sedimentary rocks in the different Carpathian units and point to mobility and circulation of fluids. Such an evidence has been already mentioned in general by Roedder (1984), and it is proved by recent publications concerning brine and hydrocarbon inclusions in the distinct zones at the Polish-Ukrainian boundary (Jankowski, JarmoÅ‚owicz-Szulc, 2011;  JarmoÅ‚owicz-Szulc et al., 2012; JarmoÅ‚owicz-Szulc, Jankowski, 2013). The analysis has been conducted pointing to a presumed HC migration in two directions. The results are important in search for hydrocarbons. 

Biography:

Vladimir Abramov has completed his PhD at the age of 26 years at the Moscow Institute of Steel and Alloys. He is a professor in technical sciences since 2007 and the head of the laboratory of ultrasonic technique and technology in his institute. He has published more than 150 papers and patents, is a member of the European society of sonochemistry and the World Assotiation for Ultrasound Applications. In 2008 he received the Russian Government Prize for achievements in the field of science and technology. He and his team has over 30 years of experience in the field of EOR.

Abstract:

 

The ultrasonic and sonochemical method of EOR is one of the most promising methods, since it can be applied for the treatment of wells, which has already been subject of EOR, horizontal wells and heavy oil wells. It was developed over 30 years ago, but only today the state of the technique enables us to deliver enough energy to the perforation zone to show significant results. The method is based on years of research and involves not only ultrasonic treatment of the perforation zone, but also preliminary analysis of the perforation zone, determination of treatment intervals for selective treatment and subsequent pump-out using a specially designed jet pump. Only in such a way the method can be economically sound, especially in case of horizontal wells.

The technology delivers an ultrasound frequency to the reservoir which has the impact of reducing skin damage, putting resins, asphaltenes and waxes back into solution, and increasing penetration into capillars resulting in enhanced production and recovery of oil. Average results are a doubling of production and in some cases up to over a 900% increase.

In case of heavy oil the effect of viscosity reduction, caused by ultrasound is particularry important, since it contributes not only the the increase of production, but also facilitates the transportation of oil. For such cases we have developed a sonochemical technique, which allows us to secure the viscosity reduction by adding chemicals afterwards.
