Abstract:

This article will discuss methods for increasing the condensate recovery coefficient and the concept of condensate recovery. Gas condensate is a cold hydrocarbon reservoir that includes natural gas as well as liquid hydrocarbons, often in the form of liquid condensate. During reservoir extraction, liquids are mixed from mixtures of light hydrocarbons (eg methane, ethane, propane) and denser liquid hydrocarbons (known as condensates). Gas condensates are found in underground reservoirs, where temperature and pressure conditions allow the gas to condense into liquid form as it moves from the for

While the depletion regime for gas-condensate fields may be more cost-effective, it often results in the loss of hydrocarbon condensate, which is economically more valuable than gas, and leads to the inefficient exploitation of the field in terms of condensate production.

Effective exploitation of gas-condensate fields involves achieving maximum hydrocarbon condensate production in addition to maximum gas production.

Abstract During the development of multilayer oil and gas condensate fields, the production of condensate is influenced by the associated oil. Analysis of field data showed that the cause of oil flows is the outstripping decrease in reservoir pressure in the gas condensate section in comparison with oil zones. Thus, incoming heavy oil fractions into a gas condensate reservoir have a negative impact on reservoir losses of hydrocarbons, including the final condensate recovery factor.

Abstract:

The article provides a brief analysis of the determination of the minimum gas flow rate required for complete removal of condensate from the wellbore in gas condensate wells. In gas wells, water collects in the wellbore as a result of condensation of produced water and steamed water entering the wellbore together with the well product. In gas condensate wells, gas condensate from the formation is added to it. Thus, part of the filters of gas and gas condensate wells is filled with liquid, which ultimately reduces the flow rate of these wells. At the beginning of the development and operation o

Abstract:

The design and forecast of the development of gas condensate fields, accompanied by the construction of hydrodynamic models (HM), is based on the PVT model of a reservoir multicomponent system. To create such a model, a technique based on equations of state and an algorithm for modeling vapor-liquid transitions of hydrocarbon mixtures is used. The studies performed in the framework of the work by the contact and differential method on the reservoir fluid model (MPF) with imitation of the process of natural depletion of the deposit proved that low condensate content leads to lower losses in the

The object of research is gas condensate fields at a late stage of their development under conditions of a decrease in reservoir pressure below the pressure of condensate separation from a gaseous state. Reservoir losses of condensate during the development of deposits in depletion mode can reach 78 %, which entails the need to use various methods of stimulating the reservoir system to remove it. The most acceptable method is the use of a cycling process by re-injection (recirculation) of the produced and separated gas into the formation. A significant disadvantage of the cycling process is th

The great majority of currently developed fields in the world are of gas-condensate type. These fields differ from oil and gas ones with their numerous physical-chemical properties. Thus, the duration of the exploitation impacts the development process. Essentially, it is associated with the drop of formation pressure, which has an effect on the process of gas-condensate delivery. The reliable definition of the time of pressure drop allows regulating the development process, which is topical in the field practice.

The adjustment is done until the moment when EOS is reproducing the results of laboratory experiments. Classic PVT experiments perfo
