“…The oilfields have a large number of geological, geophysical and geochemical data, and have a comprehensive understanding of geological models and geothermal reservoir evaluation, which provide important support for geothermal resource evaluation and development 7 , 8 . Meanwhile, the existing surface facilities, wellbores and useful data empower the oilfield geothermal project with minimized risk, reduced cost and significant convenience 9 , 10 . Therefore, the geothermal resource evaluation and development in the oilfields has been continuously studied, and a considerable amount of geothermal reservoirs are reported in worldwide oilfields 11 – 13 .…”

The development of geothermal resources in the Dongpu Depression can improve not only the economic benefits of the oilfield but also the ecological environment. Therefore, it is necessary to evaluate the geothermal resources in the region. Based on the heat flow, geothermal gradient and thermal properties, the temperatures and their distribution in different strata are calculated using geothermal methods, and the geothermal resource types of the Dongpu Depression are identified. The results show that the geothermal resources include low-temperature, medium-temperature and high-temperature geothermal resources in the Dongpu Depression. The Minghuazhen and Guantao Formations mainly include low-temperature and medium-temperature geothermal resources; the Dongying and Shahejie Formations include low-temperature, medium-temperature and high-temperature geothermal resources; the Ordovician rocks mainly include medium-temperature and high-temperature geothermal resources. The Minghuazhen, Guantao and Dongying Formations can form good geothermal reservoirs and are favorable layers for exploring low-temperature and medium-temperature geothermal resources. The geothermal reservoir of the Shahejie Formation is relatively poor, and the thermal reservoirs may be developed in the western slope zone and the central uplift. The Ordovician carbonate strata can provide thermal reservoirs for geothermal resources, and the Cenozoic bottom temperature is more than 150 °C except for most of the western gentle slope zone. In addition, for the same stratum, the geothermal temperatures in the southern Dongpu Depression are higher than those in the northern depression.

“…Table 5.5 illustrates the differential shifts of the number of employed inhabitants in each of the group of the NACE sections of employment in Table 5.2. We show the differential shifts for the compared pairs of municipalities and poviats, and poviats with voivodships (Table 3) resulting from the formula 2 computation of the employment data (Kurek et al, 2020e). The hypothesis testing concentrates on the analysis of the NACE sections 3 and 5 contribution to the total number of differential shift for each municipality and poviat.…”

“…The computations of the relative shifts formulas 4, 5 and 6 with the NACE sections employment data of 2005 and 2018 (Table 2 at Kurek et al 2020e) result in a single shift score for each of the examined geothermal municipality in reference to the poviat. The same procedure is conducted for the poviat and voivodeship pairs.…”

An advantage of the geothermal over other renewables is its non-intermittent character (Richard Wolfson, 2011). Unlike the wind, hydro or solar power the geothermal energy is continuously produced uninterrupted by any weather conditions, which means it can be used at any time of the day, any day of the year. This feature allows for a reliable baseload power provider, especially for the electric grid. The total global geothermal energy amounts to about 42 million megawatts, however only a fraction of it can be utilized (Meyers, 2012). Exploitation of this renewable is limited to areas where geological conditions permit a carrier i.e. water or steam to conduct the heat from the earth core nearer the earth surface. The Earth becomes hotter by about 25°C per kilometer of depth by average. In the geothermal hot spots, the temperature increases 60°C per kilometer of depth, creating optimal conditions for harvesting
