Stable Water Isotopes

Isotopes are atoms of the same chemical element that have the same number of protons but different number of neutrons in their nucleus. Take the same position in the table of elements, have the same chemical properties but different mass number. There are stable and unstable, i.e. radioactive isotopes (radionuclides). Oxygen, for example, has three stable isotopes: 16O, with 8 protons and 8 neutrons... [More]

Preliminary test results of gas permeability of soils and GCLs

The ability of a porous media, and also of soil, to allow the flow of a fluid through it is called permeability. Fluids passing through a porous media can be in gaseous or liquid form. The hydraulic conductivity of soil is a well-known property and it is described by an advective flow regime. However, in nature, fluid in porous media is very commonly... [More]

Paleolimnology of karst lakes in Croatia

Paleolimnology is a scientific discipline that focuses on past conditions and processes in lake basins (Last & Smol, 2001). Paleolimnologists use physical, chemical and biological indicators in lake sediments to determine the paleoenvironment and evolution... [More]

CO2-EOR Process and CO2 storage during EOR

Enhanced Oil Recovery (EOR) methods are used to produce additional oil after the primary production phase (where production is based on natural reservoir energy) or, most often, after waterflooding (secondary phase). Some EOR methods are related to CO2 injection (CO2-EOR)...  [More]

Research of extreme – explosives

One of the main aims of the research, as a part of HRZZ project NEIDEMO, is to develop an improved model of nonideal detonation, based on Wood-Kirkwood’s theory and thermochemical code EXPLO5. Detonation of explosive charge results in a detonation wave through explosive propagating with velocity up to 10 km/s...

Determination of the Earth's structure by Local Earthquake Tomography method

Knowledge of the Earth's interior is key to understanding geological structures and their relationships observed on the surface. In the last two decades, many regional studies of the European lithosphere have been carried out, while in the past ten years local geophysical researches have been intensified in the Dinarides...

Geothermal energy exploitation by revitalizing abandoned oil and gas wells

In the Republic of Croatia hydrocarbon production began back in the end of the 19th century. However, modern oil and gas production began in the mid-20th century and is still continuing today. According to data from INA d.d. group, there are around 4500 exploratory, production and development wells in Croatia (INA d.d., 2018)...  [More]
