“…The basinal Zechstein Limestone dolomites show a wide range of & Peryt, 2009), which can be related to a fault occurring close to the borehole (see Raczyński et al, 2017). Usually, the ascending mineralizing fluids, at other locations, were affecting mostly the lower part of the Lower Anhydrite (Oszczepalski & Chmielewski, 2018).…”

Pervasive dolomitization of a carbonate sequence is commonly the result of multiphase processes (e.g. Machel, 2004;Warren, 2000, with references therein), and dolomite is in fact a complex suite of early marine to late burial Mg-carbonates (see Mueller et al., 2020).Many researchers indicate that, because of complex chemical alterations, it is difficult to reveal the origin of dolomitization (Özyurt et al., 2019 and Mueller et al., 2020, with references therein). This paper deals with four condensed basinal dolomite sections deposited in the neighbourhood of reefs that formed on one of the intrabasinal highs in the Zechstein Basin in the Brandenburg-Wolsztyn-Pogorzela High (Wolsztyn High in short), SW Poland. The High consists of strongly folded, faulted and eroded Viséan to Namurian flysch deposits capped by a thick cover of Upper Carboniferous-Lower Permian volcanic rocks. This sedimentary-volcanic complex was then strongly fragmented (Kiersnowski et al., 2010). By analogy to the Permian Basin of North America (Saller & Stueber, 2018), one can expect that most of the formation waters previously present in the basin were displaced by highly saline, dense, evaporated seawater also in the Zechstein Basin during the latest Permian. Because of its high density, the seawater remained gravitationally stable in the basin and thus difficult to displace. Thermal history of the Polish Basin suggests the existence of high positive anomalies of heat flow within the distal part of the basin during its initial phase of development, and the highest heat flow during the Late Permian, Triassic and Jurassic in the area northeast of Wrocław (Karnkowski, 1999). This could trigger the intensive brine circulation that led to the development of, among others, dolomitization of basal Zechstein carbonates, in particular in the basinal facies, and the world-class Cu-Ag Zechstein-hosted mineralization that occurs in the Kupferschiefer and adjacent strata in SW Poland. This mineralization is regarded as a result of fluid-rock interaction caused by ascending migration of moderately low-temperature

“…Thanks to DWI and other supplementary studies, the researchers managed to visualize the main routes of oil migration and revealed the microstructure of algae, the analogue of which is frequently found in fossilized material (cf. Raczyński et al., 2017).…”

Prospects and Challenges for the Spatial Quantification of the Diffusion of Fluids Containing ¹H in the Pore System of Rock Cores

Nuclear magnetic resonance (MR) (NMR) is commonly used for the determination of rock porosity, as well as pore size distribution (PSD) and tortuosity, required to handle hydrocarbon exploitation. Emerging technologies for NMR equipment now enable the visualization of porosity using magnetic resonance imaging (MRI). Currently, single‐point imaging is the most common MRI technique employed, but diffusion‐weighted imaging has been attracting the attention of geologists and geophysicists. In this study, a more advanced technique, diffusion tensor imaging (DTI), is proposed for the characterization of rock core samples. The main purpose of this paper is to demonstrate the usefulness of DTI in the petrophysical characterization of rocks and discuss its strengths. As an example, a carbonate core sample was examined using DTI. The diffusion tensor (DT) was obtained and DT parameters (mean diffusivity, MD; fractional anisotropy, FA; three eigenvalues; DT components; and proton density, PD) were visualized in 2D and 3D. Each parameter was described and its utility in terms of pore space characterization was analyzed. In addition, a new parameter, principal diffusion tracts, was introduced based on the DT tractography performed in the study. The analysis is summarized in a set of DT parameters and a resultant ellipsoid that delivers complementary information about the sample's pore network microgeometry, including referential measurements of anisotropic phantoms. The applications of DTI for the determination of pore size distribution, tortuosity and conductivity are also shown. The study ends with a consideration of the potential prospects and challenges for DTI‐based examination of rock core samples.
