“…These data are not available for most geothermal complexes, which is a shortfall in our literature study. Furthermore, temperature gradient [2,8,10,11] and thermal conductivity [7] measurement of rocks for the Lithuanian geothermal complex field can be obtained from the above literature review. The detailed gamma ray log before and after injection can be obtained from reference [5].…”

“…Moreover, uncertainties arise due to limited measurements and associated costs, resulting in reliance on sparse data for material properties. Therefore, a geological 3D model must encompass heterogeneity, non-linearity, and uncertainty, making detailed geological analysis and modeling crucial for addressing geothermal challenges [5,10,16,22].…”

Lithuania is located on the East of Baltic sedimentary basin and has a geothermal anomaly situated in the southwestern region of the country. There are two primary geothermal complexes within the anomaly, composed of Cambrian and Devonian aquifers. The Cambrian formation is composed of sandstones that have a reservoir temperature reaching up to 96 °C (depth > 2000 m). The Devonian aquifer is composed of unconsolidated sands of Parnu–Kemeri and has a reservoir temperature of up to 46 °C (depth > 1000 m). Historically, both formations have been investigated for geothermal energy production. In this article, we present a detailed literature review of the geothermal work carried out on both formations, including past, present, and some possible future studies. The study presented in this paper highlights the key findings of previous research work, summarizes the research gaps, and then elaborates on the possible applications of emerging technologies to bridge the research gaps and improve our understanding of geothermal complexes in Lithuania. Although it is not the main aim of this article, this article also touches upon the important need to develop 2D/3D numerical models, to quantify uncertainties, in the evaluation of the geothermal potential in Lithuania for commercial development. This study also highlights possibilities of extending geothermal development to depleted hydrocarbon reservoirs through repurposing the high-water-production wells. Moreover, from the literature review, it can be concluded that the Lithuanian geothermal aquifers are hyper-saline in nature and temperature changes lead to the deposition of salts both upstream and downstream of the reservoir. Therefore, there is a need for developing multiphysics thermo-mechanical–chemical (THMC) models for evaluation of reservoir behavior. The literature also describes the potential use and development of the THMC model as a part of future work that must be carried out.

“…Subsequently, the Baltic geothermal project was initiated in 1992, which led to the drilling of a number of other wells for geothermal exploration. Geothermal exploration led to the development of the Klaip ėda Geothermal Demonstration Plant, Geoterma, which was the first geothermal heating plant in the Baltic Sea region [2][3][4][5][6][7]. The Geoterma plant made use of the 38 • C water from a Devonian sandstone aquifer located at depth of 1135 m [2][3][4][5][6][7].…”

The Geoterma plant made use of the 38 • C water from a Devonian sandstone aquifer located at depth of 1135 m [2][3][4][5][6][7]. Over time, the Geoterma project experienced operational and financial difficulties because of decreasing production rates and challenges related to water injection issues and not being able to compete with the cheap energy produced at the nearby and newly-opened incineration plant, resulting in its bankruptcy and eventual closure in 2007 [8][9][10].…”

Lithuania has a geothermal anomaly situated in the southwestern region of the country. This anomaly is comprised of two primary geothermal complexes located in western Lithuania. The first complex is characterized by the Pärnu–Kemeri Devonian sandstone aquifers, which exhibit exceptionally good flow properties. However, the reservoir temperatures in this complex only reach up to 45 °C. The second complex encompasses Cambrian sandstone reservoirs. Although these Cambrian sandstone reservoirs exhibit high temperatures, with the highest reservoir temperatures reaching up to 96 °C, these Cambrian sandstone reservoirs have less favorable petrophysical properties. This study focuses on the high temperature Cambrian Geothermal sandstone reservoirs. The study aims to conduct a geological screening of the existing and depleted hydrocarbon reservoirs with high water production rates. After initial data gathering, numerical modeling is employed with the help of mechanistic box models to evaluate the geothermal potential of the selected sites for commercial development. Ultimately, the study identifies the top five screened sites, which could be developed further for techno-economical modelling.
