The article considers the hydro dynamic modelling of gas condensate fields development depletion based on differential condensation of a condensate mixture. The proposed calculation method was to perform numerical experiments to demonstrate the role of the ethane-propane-butane fractions in interphase mass transfer processes.

The article deals with the study of steady-state research. Oilwells sucker-rod pumps at wells No54, No36 and No417 at Kalmas, OGPD named after A.Amirov were studied. Well test-based crossplot of drawdown vs flow rate have been presented. The studies show availability of distinctions between flooded and water-free wells based on diagrams and their interpretation.

The effectiveness of investment due to postponement of the implementation of oil production is evaluated given the time factor and price trends for the development and exploration of oil fields. More efficient use capital for oil field development can be obtained using a suitable delay for the implementation of investment projects.

The applications of horizontal well technology in developing hydrocarbon reservoirs have been widely used in recent years. One of the main objectives of using this technology is to improve hydrocarbon recovery from water and/or gas-cap drive reservoirs. The advantages of using a horizontal well over a conventional vertical well are their larger capacity to produce oil at the same drawdown and a longer breakthrough time at a given production rate. Coning is a term used to describe the mechanism underlying the upward movement of water and/ or the down movement of gas into the perforations of a producing well. Coning can seriously impact the well productivity and influence the degree of depletion and the overall recovery efficiency of the oil reservoirs. Delaying the encroachment and production of gas and water are essentially the controlling factors in maximizing the field's ultimate oil recovery. Since coning can have an important influence on operations, recovery, and economics, it is the objective of this paper to develop a computer program for calculating the critical oil (or gas) rate to avoid coning of unwanted fluids into production wells and to predict the behavior of water and gas coning in horizontal wells.

In the article the reliable determination of information collection which is used in oil and gas production modeling, it is proposed to apply a dynamic analysis of primary technological measures. Fundamental methodologies for evaluation of recovered volumes of hydrocarbons were introduced and applied during the analysis of results of laboratory experiments on displacement of oil from porous medium with water and by primary technological measures in the "Neft Dashlari" oilfield development. The approach developed permits the collection of reliable predicted values of recoverable volumes of hydrocarbons with consideration of transient processes in formation system and also to make reasoned decision in management and selection of strategy in oil and gas field development.
