  - Year 2019

  Several studies have indicated the presence of more than one generation of bitumen that could be isolated from rocks through sequential extraction or after demineralization or both. Nabbefeld et al. (2010a) and Holman et al. (2012, 2014) termed bitumen obtained after solvent extraction from the undigested rock as “Bitumen I" and that obtained by extraction after demineralization of rock as “Bitumen II.” The occurrence of different...

  A 137-m continuous core from the Jurassic-Early Cretaceous marine derived oil shale with the maturity Ro about 0.7 %, representing the oil window in the Vaca Muerta Formation, Neuquén Basin, Argentina, was examined using geological, mineralogical, petrographic, and geochemistry techniques. Three distinct intervals were identified within the core: the upper carbonate-rich section with intense bioturbation, indicating dysoxic to...

  - INTERNATIONAL JOURNAL OF COAL GEOLOGY - Year 2019

  This paper investigates chemical functional groups of the two extracted bitumen fractions in shales of the Jurassic to early Cretaceous Vaca Muerta Formation of the Neuquén Basin in Argentina, South America. The results indicate that Bitumen I is strongly aliphatic and appears to be genetically related to fluorescent amorphous organic matter. In contrast, Bitumen II consists of highly condensed, aromatic hydrocarbons, and has some...

  - Year 2018

  Research focuses on analyzing the role of rock constituents in kerogen transformation. It includes mineral and organic matter characterization, kerogen and bitumen isolation, quantification, and determination of the critical factors of transformation ratio concerning generating mobile versus less mobile hydrocarbons. The results indicate that the ratio mainly depends on the distribution and type of kerogen in the basin, and secondly...

• The role of organic and mineral constituents on kerogen transformation ratio

  Publication

  • A. Małachowska

  - Year 2015

  The main aim of this dissertation is to determine the role of mineral and organic matter constituents in kerogen transformation ratio. Practical aspects of the work include application of the results in the assessment of hydrocarbon production potential; to make process of hydrocarbon recovery more predictable consistent and efficient. The work used shale from the Vaca Muerta formation from the Nequen basin in Argentina. The formation...

  - Przegląd Elektrotechniczny - Year 2012

  In this paper application of innovative multi-DBD plasma actuator for flow separation control is presented. The influence of the airflowgenerated by this actuator on the flow around NACA 0012 and NACA 0015 airfoil models was investigated. The results obtained from 2D PIVmeasurements showed that the multi-DBD actuator with floating interelectrode can be attractive for leading and trailing edge separation control.

  - Year 2020

  Rozdział dotyczy zasad efektuacyjnego modelu przedsiębiorczości jako odpowiedzi na wyzwania związane ze zmiennością, niepewnością, niejednoznacznością i złożonością otoczenia (tzw. rzeczywistość VUCA), w którym realizowane są projekty w gospodarce cyfrowej. Na tle rozważań teoretyczno-koncepcyjnych przedstawiono wyniki badań empirycznych, które przeprowadzono w zespołach projektowych IT o różnym poziomie wirtualności. Wskazano...

  - Year 2018

  Scharakteryzowano materię organiczną formacji łupkowych w odniesieniu do jej związku z minerałami metalonośnymi. W szczególności analizowano kerogen, ze względu na właściwości, stan skupienia i związanie z materią mineralną. Zestawiono najbardziej efektywne metody pozwalające na skuteczny rozdział materii organicznej i minerałów metalonośnych ze skał łupkowych, celem uzyskania koncentratu o najwyższej jakości. Omówiono flotację...
