Offshore deep water oil drilling

The difference between offshore deep water drilling of oil wells and shallow water drilling lies in the indicator of the depth at which the work is carried out. The process of extraction of minerals (oil) occurs with the help of mobile platforms and installed equipment. The concept of deep-sea drilling is defined for works that are carried out at a depth of more than 600 meters. Offshore deep water drilling is carried out with the help of equipped drilling vessels with the property of dynamic stability. Greater depth is marked by the probability of a slight deviation of the drill from the initial position. With this type of oil production, a deviation of the well radius in the amount of three percent of the sea depth is allowed. Crosswinds or frontal winds up to forty-five knots are allowed

ECONOMIC EFFICIENCY OF THE GHG EMISSIONS FROM ENERGY USE IN AGRICULTURE: COMPARATIVE ANALYSIS OF UKRAINE AND THE EU MEMBER STATES

The article is devoted to the study of the economic efficiency of GHG emissions from the use of energy in agriculture in the EU and the candidate country for accession - Ukraine. Using the abstract-logical method, the essence of the category "economic efficiency of greenhouse gas emissions" was clarified and an indicator for its assessment was proposed. By actual statistical data and the method of economic analysis, calculations of the economic efficiency of carbon dioxide emissions from the use of energy in agriculture of the EU member states and Ukraine were made. The key factor influencing the economic efficiency of GHG emissions from energy consumption in the agricultural sector was identified. Due to econometric method of approximation estimation and the Excel software package, the presence of a direct, high-density linear relationship between energy consumption and carbon dioxide emissions in agricultural production was established. By ranking method and comparative economic analysis, a threshold value of energy consumption per hectare of agricultural land was found, which corresponds to a relatively high value gross production per ton of carbon dioxide emissions among the studied countries. It was established that for the candidate country for joining the EU - Ukraine and for the two Baltic countries - Latvia and Estonia, in order to increase the level of economic efficiency of GHG emissions in terms of implementation the European Green Deal, it is worth paying primary attention to the growth of economic productivity. Also, due to graphical and tabular methods of processing statistical data, it was established that the use of environmentally friendly energy (in particular, electric energy) in the process of agricultural production is not a key factor affecting the economic efficiency of GHG emissions

Oil wellhead equipment

Regardless of the extracted resource, the mouth is an extremely important functional element of the system. The productivity and efficiency of production, as well as convenience during the drilling process, depend on it. When arranging oil production points, special attention is paid to the mouth. Regardless of whether an oil well or not, according to the generalized definition, the mouth is the intersection of the surface of the upper soil by the mine, i.e. the most loose and unstable reservoir
