Overview

Top Research Topics at Geothermal Energy?

The journal focuses on Geothermal gradient, Geothermal energy, Borehole, Petroleum engineering and Petrology. The Geothermal gradient research dealing mostly with Geothermal exploration is the focus of it. It holds forums on Geothermal energy that merges themes from other disciplines such as Aquifer and Renewable energy.

It explores research in Borehole alongside concepts in Heat exchanger and other areas of study in Mechanics. The study on Petroleum engineering presented in Geothermal Energy intersects with the topics under Energy technology. Petrology research presented in the journal encompasses a variety of subjects, including Structural basin, Tectonics, Permeability (earth sciences), Fault (geology) and Well logging.

Geothermal Energy explores issues in Permeability (earth sciences) which can be linked to other research areas like Porosity and Dissolution. It explores the study of Fault (geology) to improve our understanding of the broader topic of Seismology. The Geochemistry study tackled is a key component of adjacent topics in the area of Geomorphology.

What topics the last edition of the journal is best known for?

  • Thermodynamics
  • Mechanical engineering
  • Sedimentary rock

The previous edition focused in particular on these issues:

Geothermal Energy primarily tackles Geothermal gradient, Geothermal energy, Petroleum engineering, Borehole and Petrology. The studies on Geothermal gradient discussed can also contribute to research in the domains of Sedimentary rock, Geochemistry, Drilling and Well logging. Issues in Geothermal energy were discussed, taking into consideration concepts from other disciplines like Energy supply and Emerging technologies.

The tackled Petroleum engineering research is interrelated with Nameplate capacity which concerns subjects like Induced seismicity, Fault (power engineering) and Lead (geology). While work presented in it provided substantial information on Borehole, it also covered topics in Structural basin, Heat exchanger, Overburden and Aquifer. Carbonate, Fault (geology), Hydrothermal circulation and Molasse are some topics wherein Petrology research discussed in the journal have an impact.

Publication chance based on affiliation

The publication chance index shows the ratio of articles published by the best research institutions in the journal edition to all articles published within that journal. The best research institutions were selected based on the largest number of articles published during all editions of the journal.

The chart below presents the percentage ratio of articles from top institutions (based on their ranking of total papers).Top affiliations were grouped by their rank into the following tiers: top 1-10, top 11-20, top 21-50, and top 51+. Only articles with a recognized affiliation are considered.

During the most recent 2021 edition, 4.35% of publications had an unrecognized affiliation. Out of the publications with recognized affiliations, 40.91% were posted by at least one author from the top 10 institutions publishing in the journal. Another 18.18% included authors affiliated with research institutions from the top 11-20 affiliations. Institutions from the 21-50 range included 18.18% of all publications and 22.73% were from other institutions.

Returning Authors Index

A very common phenomenon observed among researchers publishing scientific articles is the intentional selection of journals they have already attended in the past. In particular, it is worth analyzing the case when the authors participate in the same journal from year to year.

The Returning Authors Index presented below illustrates the ratio of authors who participated in both a given as well as the previous edition of the journal in relation to all participants in a given year.

Returning Institution Index

The graph below shows the Returning Institution Index, illustrating the ratio of institutions that participated in both a given and the previous edition of the conference in relation to all affiliations present in a given year.

The experience to innovation index

Our experience to innovation index was created to show a cross-section of the experience level of authors publishing in a journal. The index includes the authors publishing at the last edition of a journal, grouped by total number of publications throughout their academic career (P) and the total number of citations of these publications ever received (C).

The group intervals were selected empirically to best show the diversity of the authors' experiences, their labels were selected as a convenience, not as judgment. The authors were divided into the following groups:

  • Novice - P < 5 or C < 25 (the number of publications less than 5 or the number of citations less than 25),
  • Competent - P < 10 or C < 100 (the number of publications less than 10 or the number of citations less than 100),
  • Experienced - P < 25 or C < 625 (the number of publications less than 25 or the number of citations less than 625),
  • Master - P < 50 or C < 2500 (the number of publications less than 50 or the number of citations less than 2500),
  • Star - P ≥ 50 and C ≥ 2500 (both the number of publications greater than 50 and the number of citations greater than 2500).

The chart below illustrates experience levels of first authors in cases of publications with multiple authors.
