The article present the results of use of the proposed economic and mathematical apparatus to develop scenarios that provide for the partial or complete elimination of contradictions associated with the pricing policy between oil and gas production and the production of refined products. In the output we noted changes in the material consumption of products of the oil and gas sector of Ukraine. We corrected a certain contradiction between the extractive and processing enterprises of the oil and gas sector. This is related to the uneven distribution of value added between them, which allows extractive enterprises to make a profit, while processing enterprises are at a breakeven point. This situation, as we have seen, also distorts the results of the real assessment of resource efficiency in this sector of the economy. Thus, the research is aimed at developing scenarios that provide for a gradual decrease in the price of extractive products and its simultaneous growth in processing so that the corresponding impact on the economy was minimal. The first scenario envisaged a reduction in the price by –10% for the products of oil and gas companies with a simultaneous increase in the price of refining so that the average share of value added in the country as a whole was not decreased, taking appropriate adjustments of resource efficiency indicators into account. The second scenario was based on the need for deeper price adjustments in the oil and gas sector. Thus, the reduction of the price of products at the extractive enterprises at the level of –20% and its increase it in processing while maintaining the national average share of value added was envisioned. The third scenario provided for the equalization of material consumption in production and processing due to the price factor.

In this study some of the experimental results of water shut-off treatments in oil and gas production wells were presented. The effect of water saturation of Miocene rocks of the Carpathian Foredeep on the relative permeability to gas was analyzed. Also, wide review of the worldwide publications from the point of view of the results obtained in water shut-off treatments in oil and gas formation was presented. Based on experimental results efficiency of relative permeability modification of sandstone from Szydłowiec to brine and nitrogen by four selected chemicals polymers and microgels was evaluated. Experimental results indicated that trend changes of permeability modification strongly depends on the fluid used in the RPM treatment. Moreover, efficiency of permeability modification to brine depends on flow rate of brine through the core - the lower brine flow rate the higher efficiency of the RPM treatment. RPM product number 1 caused significant loss of permeability to brine ca. 60% and slight permeability modification to gas ca. 18%. This permeability change to brine and gas was obtained by modification of formation wettability what affects well productivity. In the case of product number 2 which is based on microgels technology, also significant modification of selective permeability to brine was observed. Loss of permeability to brine was in the range of 65 to 90% while to gas ca. 50%.
