When, for a hydrocarbon deposit, the porosity, density and saturation of the rock, saturating fluid, the permeability, and the electrical formation factor are known, formulas for calculating the equivalent thermal conductivity can be used, by which this property is expressed, depending on the properties of deposit, more easily measurable.
These computational expressions are the result of correlations between experimental determinations performed for the physical properties of a very large number of samples in the field.
But these equations introduce measurement errors or interpretations by the authors of the research, which often lead to quite large differences from reality.
That is why we introduced an experimental model to determine the thermal conductivity and we determined this property on rocks taken from the productive layers of crude oil and gas from some geological research wells conducted in the Moesica Platform, Romania.
We also managed to introduce computational relationships between thermal conductivity and density and porosity of extracted rocks.
The role of these experiments is to find a new method for determining the thermal conductivity, a property necessary to simulate the flow of oil fluids and the design of oil recovery techniques.
