Metasomatic dolomitization and oil-and-gas content of carbonate rocks

DOI:

It is shown, that the natural metasomatic nanoprocesses promote the formation of high-yield reservoirs, especially in
carbonate rocks of the Phanerozoic. It is proposed to initiate the accelerated technogeneous process of metasoma -
tic dolomitization and create high-yield centers in the fields. As a result the voids specific surface will be increased,
many processes in the reservoir system will be activated: the fracturing formation, fluid mass flow from the block matrix
to the fissures and even the formation of new hydrocarbon masses. Percolation processes will be greatly intensified,
wells deliverability and oil recovery will be increased. Successful exploitation of the proposed nanotechnology can
have a significant influence on the time of field development and final oil recovery ratio.

Cross-well electromagnetic investigation – EMI data modeling. Efremov field case study

DOI:

Successful operation (high flowrates) of a future well is greatly dependent on selecting a correct target for sidetra cking. Application of a well logging tool that allows determining current saturation of the formation in the cross-well area enab les to reduce uncertainty in the process of sidetrack candidate selection. Cross-well electromagnetic investigation – EMI* is one of such tools that records distribution of electromagnetic properties of rocks in the cross-well area. In depositional environment of typical terrigenous sedimentary section of the Efremov field this method becomes an informative solution for selecting the areas for infill sidetrack drilling.

On evaluation of absolute, effective and relative permeability of terrigenous reservoirs

DOI:

Correct evaluation of reservoir permeability is critical today. This is attributed to several reasons, including increased number of complex reservoirs and decline of oil and gas production levels. Correct evaluation of oil, gas, and water effective and relative permeability, apart from absolute permeability, which nowadays is most commonly used to study oil and gas reservoirs, will allow to identify reservoirs in the well cross-section, estimate inflow behavior, and predict production rates more effectively.

Methodological aspects of extracting and analysis of gas with sulfur-containing components

DOI:

Disadvantages, concerning the extraction of natural gas with a touch of sulfur-containing compounds, are revealed. It is noted that the existing GOST on determination of sulfur-containing compounds in natural and liquefied gas can only determine of hydrogen sulfide and the total content of mercaptan sulfur. An attempt was made by the example of one of the fields to minimize the influence of extraction conditions on the content of sulfur-containing compounds in petroleum gas.
