Abstract:

This article discusses a system for developing an oil reservoir using the pressure of regional waters. The system is used for reservoir-type oil deposits with natural water pressure or active elastic water pressure regime. It involves drilling out the deposit with production wells, locating them mainly in the purely oil part of the deposit in closed (“circular”) rows parallel to the internal oil-bearing contour. This includes oil deposits with effective reduced wear regimes of deposits with water-pressure and active elastic-water-pressure regimes. Waterflooding cannot be developed when the per

Abstract:

Chromium plated cylinder has been wildly used in large bore diesel engines due to its light weight, good durability, and low induced liner wear. Deposits accumulated in the grooves and micro-crack on chromium plated cylinder could smooth the running surface, reduce the oil retention capability, and increase the engine’s oil consumption. In the present research, deposit formation on chromium-plated cylinder in fully formulated oil under different loads and temperatures was investigated by using a reciprocating sliding tester. Surface analytical techniques such as SEM, EDX, and XPS have been use

Abstract Asphaltene deposition from crude oil, induced by n-heptane and acetone flows in a microfluidic device, was studied by optical and FTIR spectroscopic imaging techniques in situ. It was found that n-heptane and acetone penetrate crude oil in completely different ways, which is responsible for the formation of deposits with different structures and chemical compositions. The contact of the n-heptane flow with crude oil leads to fast aggregation of asphaltenes at the interface, resulting in the formation of a compact deposit fixed to the surface. Subsequent slow diffusion of n-heptane int

Experiences show that the concentration of hydrocarbon gases increases with increasing depth in places where oil and gas deposits are suspected, and the composition of the gas becomes very close to the composition of the deposit as it approaches the deposit.

Abstract Currently, during the period of heavy oil, the problem of combating and removing asphalt-resin-paraffin deposits comes first both in oil production, transportation, processing and storage of oil. If it was not possible to prevent the accumulation of deposits in pipes, oil pipelines, tank farms, then it should be removed. Asphalt-resin-paraffin deposits can be removed in various ways: mechanical, thermal, chemical, etc. Knowing the melting point of asphalt-resin-paraffin deposits or the dependencies that affect this parameter, it is possible to reduce the cost of thermal removal of dep

Although the Outer zone of the Precarpathian foredeep is one of the oldest gas extraction regions of Ukraine it is still promising for the exploration of new oil and gas deposits. The main gas deposits are open here in the Miocene, but the number of unidentified structures is rapidly shrinking. The development of unexplored Cretaceous deposits and the possibility of opening up their deposits of oil and gas can provide an increase in the resource base. In this case, the importance of the prospects of oil and gas bearing capacity of Cretaceous deposits is determined by a set of criterion feature

It is necessary to develop valuation tools accounting high uncertainty of input data on the exploitation of oil and natural gas resources, flexibility of their development by formation of rational production strategy with volatility

In the world's oil and gas-bearing basins, there are known examples of an increase in the reserves of hydrocarbon deposits as a result of inflow of fluids from the deep subsoil. Recently, the theory of the Earth degassing is gaining popularity. There are more and more arguments in favor of the fact that in many oil- and gas-bearing provinces of the world, oil and gas deposits are constantly replenished due to the migration of hydrocarbons through degassing pipes.
