Geothermal Resources Recognition and Characterization on the Basis of Well Logging and Petrophysical Laboratory Data, Polish Case Studies

Examples from the Polish clastic and carbonate reservoirs Central Anticlinorium, Carpathians Carpathian Foredeep are presented to illustrate possibilities of using well logging geothermal resources recognition characterization. Firstly, there was a short description selected logs methodology determination petrophysical parameters useful in investigations: porosity, permeability, fracturing, mineral composition, elasticity orogeny mineralization formation water logs. Special attention allotted spectral gamma-ray temperature show their usefulness radiogenic heat calculation flux modelling. Electric imaging advanced acoustic provided with continuous information on natural induced fracturing improved lithology recognition. Wireline production were discussed present wealth methods that could be used. A separate matter thermal conductivity laboratory experiments or calculated results comprehensive interpretation logs, i.e., volume mass minerals composing rocks. It proven that, investigations hydrocarbon prospection, same considered, well-logging acquisition equipment processing interpretation, developed for almost one hundred years, can successfully used detection characterization potential reservoirs. shown newest (current investment)—as as old type (archive)—logs provide information.
