“…In particular, VR has a significant potential in the field of earth sciences as it allows exploring inaccessible areas of the past, present, or future or existing remote areas not only by static objects such as videos and photos but also by processes reflecting their true dynamics (Halik & Smaczyński, 2018;Havenith et al,, 2019;Lin et al, 2015). Data visualization and 3D modelling have been frequently studied in the field of earth sciences in recent years (Jones et al, 2009;Romañach et al, 2015;Yang & Wang, 2019;Yang et al, 2019). With the development and spread of HMD systems and relative fall in their prices, VR systems now allow visualizing, integrating, manipulating, and querying geospatial data through embodied experiences (Halik & Smaczyński, 2018;Huang & Chen, 2019;.…”

Today, earth sciences engineering education programs face with serious problems. It is often not possible to provide experience on different geographical environments or materials. Considering these problems of earth science related engineering education programs, virtual reality environment potentially can provide technology enhanced training alternatives. However, in the literature there are not many studies showing how virtual reality can enhance the earth science related engineering education programs. Accordingly, the aim of this mapping of the literature and systematic review study is to explore studies dealing with virtual reality in the earth sciences engineering education programs. Through a rigorous screening process, the first search in the Scopus database provided 150 studies, where 19 of them were selected in the course of this study and the mapping of the literature report was drawn with all these articles. Additionally, with seven of these articles a systematic review is conducted. The mapping of the literature report shows that studies on this topic have increased in recent years and have been published in a variety of journals. The number of China and USA origins studies are remarkable among the examined studies, which are predominantly in the fields of mining engineering and geological engineering. As a result of the in-depth analyses, the systematic review report indicates that virtual reality applications in the earth sciences engineering education positively contribute to the learning outcomes and experiences of students/trainees from different perspectives.

“…The second approach, implicit surface representation, uses isovalues of one or several scalar fields in 3D space to represent the geometry of geological surfaces (e.g. stratigraphic horizons and fault surfaces) (Jessell, 1981;Calcagno et al, 2008;Caumon et al, 2013;Cowan et al, 2003;Frank et al, 2007;Hillier et al, 2014;Lajaunie et al, 1997;Mallet, 2002Mallet, , 2014Maxelon et al, 2009;Moyen et al, 2004;Yang et al, 2019;Renaudeau et al, 2019;Manchuk and Deutsch, 2019;Gonçalves et al, 2017;De La Varga et al, 2019). The value of the scalar field represents the distance away from a reference horizon.…”

“…These interpolation methods mean models can be created with less bias and are more reproducible. Implicit methods also make it possible to generate a set of model realisations reflecting geological uncertainty (Manchuk and Deutsch, 2019;Cherpeau et al, 2010;Henrion et al, 2010;Wellmann et al, 2010;Lindsay et al, 2012;Yang et al, 2019).…”

Abstract. Without properly accounting for both fault kinematics and faulted surface observations, it is challenging to create 3D geological models of faulted geological units that are seen in all tectonic settings. Geometries where multiple faults interact, where the faulted surface geometry significantly deviate from a flat plane and where the geological interfaces are poorly characterised by sparse data sets are particular challenges. There are two existing approaches for incorporating faults into geological surface modelling: one approach incorporates the fault displacement into the surface description but does not incorporate fault kinematics and in most cases will produce geologically unexpected results such as shrinking intrusions, fold hinges without offset and layer thickness growth in flat oblique faults. Another approach builds a continuous surface without faulting and then applies a kinematic fault operator to the continuous surface to create the displacement. Both approaches have their strengths, however neither approach can capture the interaction of faults within complicated fault networks e.g fault duplexes, flower structures and listric faults because they either \\begin{inparaenum}[(1)] \\item impose an incorrect (not defined by data) fault slip direction; or \\item require an over sampled data set that describes the faulted surface location\\end{inparaenum}. In this study we integrate the fault kinematics into the implicit surface by using the fault kinematic model to restore observations and the model domain prior to interpolating the faulted surface. This approach can build models that are consistent with observations of the faulted surface and fault kinematics. Integrating fault kinematics directly into the implicit surface description allows for complex fault stratigraphy and fault-fault interactions to be modelled. Our approaches show significant improvement in capturing faulted surface geometries especially where the intersection angle between the faulted surface geometry and the fault surface varies (e.g. intrusions, fold series) and when modelling interacting faults (fault duplex).

“…The potential advantages of visualization form the conditions for the use of visualization tools in solving urgent problems in many areas of human activity: medicine, technology, economics, law, etc. Controlled performance visualization tools are widely used as an applied tool for scientific research [15][16][17][18][19][20][21][22][23].…”

The validation of initial data is an important process to reduce the risk of errors in calculations. The large amount of heterogeneous data in the area of hydrocarbon reservoirs development leads to a significant increasing in complexity and calculation time of data validation. Here, we consider the problem of validation and completion of the initial data for the task of hydrocarbon reservoirs development. A validation and completion method, based on the use of 3D visual models and searching of analogies, is proposed. The results of testing the proposed method on the data of reservoirs of the Tomsk region of the Russian Federation are shown. The results showed that the time of the procedure of validation and completion of the initial data was reduced by 22.2% for projects of reserve calculation and by 32.2% for projects of development forecast in comparison with standard manual validation procedure. During the validation, experts identified 18% and 13.5% more errors with the proposed method for projects of reserve calculation and development forecast, respectively, showing that the proposed method could be an effective tool for data validation and completion.
