The Relationship

The authors created a geodynamical polygon on the Komsomolsk oil and gas condensate field to ensure the industrial safety of oil and gas production facilities. The aim of its creation is mul-tiple repeated observations of recent deformation processes. Analysis and interpretation of the results of geodynamical monitoring which includes class II leveling, satellite observations, radar interferometry, exploitation parameters of field development provided an opportunity to identify that the conditions for the formation of recent deformations of the earth’s surface is an anthropogenic factor. The authors identified the relationship between the formation of subsidence trough of the earth’s surface in the eastern part of the field with the dynamics of accumulated gas sampling and the fall of reservoir pressures along the main reservoir PK1 (Cenomanian stage).

Oil And Gas Production

Results are given of oil and gas production in the long-lived fields Bibieybat and Garadag of the Absheron Peninsula, South Caspian Basin (SCB). The analysis for the Bibieybat oil field covered the period from 1935 to 2018, and for the Garadag gas condensate field from 1955 to 1979. The development is the Productive Series (lower Pliocene) - main reservoir of the SCB. The intensive development of these fields leads to the disturbance of the natural dynamic equilibrium established in the reservoir over geological time. A sharp drop of formation pressure (significantly lower than hydrostatic) during field development contributes to the natural inflow of hydrocarbon fluids to the reservoir. The rate of natural oil replenishment calculated for 29 operating facilities of the Bibieybat field varies per well within 0.32-1.4 ton/day (averaging 0.76 ton/day) or about 277 ton/year. The rate of natural gas inflow at the Garadag gas condensate field is different for its various blocks, averaging 5.2 thousand m3/day per well. Stable oil and gas production and the equivalent rate of natural recharge are determined by the influence of a complex of factors, of which reservoir pressure, temperature and permeability of the reservoir rocks are dominant.

Value Streams

This work conducts a technical analysis of the current production and consumption of vegetable oils and some of the oily byproducts to determine the potential feedstock for the synthesis of non-food-competitive surfactants and surfactant-based systems. It defines the concentrated phosphatides (phosphatidic sludge) as no-/low- value streams, appropriately suited for chemical valorisation. The study further creates biobased surfactants by amidation of phosphatidic sludge derived from refinery of sunflower and rapeseed oils with monoethanolamine, N-(2-hydroxyethyl)ethylenediamine, or N,N’-bis(2-hydroxyethyl)ethylenediamine, under the action of calcium hydroxide as catalyst in excellent yields (95–98 %). Besides waste remediation, the use of phosphatides enabled to create the mixed surfactant compositions, comprising fatty acid alkanolamides and calcium glycerolphosphatides with improved solubility in organic non-polar solvents. With new surfactants, there have been created reversed emulsion systems, which can be potentially applied to the development and exploitation of gas and oil deposits are recommended for drilling wells, the disclosure of productive strata; perforation of wells and development of productive layers; blockage of gas, gas condensate and oil wells; elimination of manifestations and flow of gas in wells; limitation and elimination of waterways; cleaning of the hollow zone of wells and intensification of the inflow of hydrocarbon raw materials, which have been tested in laboratory and experimental industrial conditions, and a significant part of them have been introduced or tested on gas condensate fields. Creation of coordinated, effective and economical actions that should be formed in the state energy policy of Ukraine would facilitate the development of oil and gas companies, namely: increase of own oil and gas production; maximizing the potential of energy saving; diversification of external sources of supply; approximation of the parameters of the oil and gas industry to the norms and standards of the European Union.

Complex Well

It is shown that the changed conditions of gas and gas-condensate fields operation entailed an increase in complexity of well repairs using coiltubing technologies. However, the methods developed for wells recovery in terms of emergency-refurbishment and water-influx restriction works are not provided for by the existing classification of complex well repairs which makes difficult to justify the length of repair works and, accordingly, their cost. The suggested amendments to the current structure of wells repair types promote further development of technologies of well workover in the conditions of oil and gas production decline .
