The paper describes the results of studying the composition and properties of pyrocarbon obtained during the pyrolysis of rubber waste. The ability of pyrocarbon to absorb oil and oil products was determined using four developed methods. It has been established that pyrocarbon can find practical use as an adsorbent for the collection and localization of spills of oil and oil products on solid and water surfaces.

The article is devoted to the process of extraction of oil from rapeseed and sunflower seeds and meal by an extraction method based on the study of the kinetic regularities of the process.

The mobile geophysical technology include a special method of the remote sensing data processing and interpreting, aerial mapping method of the forming short-pulsed electromagnetic field (FSPEF), method of vertical electric-resonance sounding (VERS). Inclusion of such technologies in traditional complex of exploration geological-geophysical methods will promote both minimization of the financial expenses on the oil-and-gas exploration problems solving, and essential reduction of time for their practical realization.

The analysis of forecast for potentially oil-and-gas bearing areas within has been provided by direct methods. The complexification approach of geochemical and geophysical methods for increasing performance of hydrocarbons deposits exploration has been considered.

The fractional composition and physical and chemical properties of light fractions selected from Orhovytsk oilfield oil аre investigated. The potential content of fractions is determined. We have studied defined density, refractive index, molecular weight and sulfur content of the mentioned fractions. The structure and group composition is calculated with the help of n-d-M method. Досліджено фракційний склад та фізико-хімічні властивості світлих фракцій, виділених із нафти Орховицького нафтового родовища.

Purpose. The results of the application of frequency-resonance technology of remote sensing (RS) data processing and interpretation and geoelectric methods of forming short-pulsed electromagnetic field (FSPEF) and vertical electric-resonance sounding (VERS) for gas accumulations searching in tight sandstones of Dnieper-Donetsk basin (DDB) are analyzed. Design/methodology/approach.

Purpose. The results of the hydrocarbon (HC) potential assessment of some structures and fields in Barents Sea by the frequency resonance method of the remote sensing (RS) data processing and interpretation are discussed. Design/methodology/approach. Experiments were carried out with the mobile technology of frequency-resonance processing and interpretation of remote sensing data using, which is the "direct" method of mineral deposits exploration and operates within the "substantial" paradigm of geophysical investigations.

Infrared spectrometry and spectrofluorimetry methods were correlated in the measurement of oil concentration in produced water. Furthermore, we compared colorimetry and gravimetry techniques. Adsorption experiments were performed in synthetic oily wastewaters by polymer compounds based on poly(hydroxyethyl acrylamide  and polypropylene. The residual oil content was used in the techniques correlation.
