Research of hard-to-recovery and unconventional oil-bearing formations according to the principle «in-situ reservoir fabric»

Article preview

Currently in Russia and the world due to the depletion of old highly productive deposits, the role of hard-to-recover and unconventional hydrocarbons is increasing. Thanks to scientific and technical progress, it became possible to involve in the development very low permeable reservoirs and even synthesize oil and gas in-situ. Today, wells serve not only for the production of hydrocarbons, but also are important elements of stimulation technology, through which the technogenic effect on the formation is carried out in order to intensify inflows. In this context, the reservoir itself can be considered as a raw material for the application of stimulation technologies, and the set of wells through which it is technologically affected is a plant or a fabric whose intermediate product is the stimulated zone of the formation and the final product is reservoir hydrocarbons. Well-established methods for studying hydrocarbon deposits are limited to the definition of standard geological parameters, which are commonly used for reserves calculations (net pay, porosity, permeability, oil and gas saturation coefficient, area), but they are clearly insufficient to characterize the development possibilities using modern stimulation technologies. To study objects that are promising for the production of hydrocarbons, it is necessary to develop fundamentally new approaches that make it possible to assess the availability of resources depending on the technologies used, and to improve the methods for forecasting and evaluating the properties of the stimulated zone of the formation. «In-situ reservoir fabric» is a collective term that combines a combination of technologies, research and methodological approaches aimed at creating and evaluating a stimulated zone of the formation by applying modern methods of technogenic impact on objects containing hard-to-recover and «unconventional» hydrocarbons in order to intensify inflows from them hydrocarbons. In 2015, the company LLS Gazprom Neft adopted a corporate standard regulating a set of studies in the ideology of the «in-situ reservoir fabric» for methodological support of the pilot projects related to development of low-permeability rocks of the Bazhenov formation by creating artificial permeable zones by multi-stage hydraulic fracturing in horizontal wells. In 2016 the first wells were built and put into operation, the results of the works confirmed the expediency of transition to a new methodological basis. After two years, we can state with certainty that the new approaches have proved their effectiveness.

Modeling of batch gold leaching process by cyanidation

Article preview

A kinetic gold leaching model, based on the well-known shrinking core model, is presented in this work. The model considers the effects of internal diffusion, surface reaction and unreacted amount of gold in the concentrate particle during leaching. The model parameters are estimated by minimization of mismatching between experimental data and results of numerical computation of kinetic model made by using ReactOp  software.

Изучение геологического строения, механических свойств и состояния горных пород месторождений полезных ископаемых для прогноза устойчивости выработанных пространств и охраны дневной поверхности

Article preview

При разработке месторождений полезных ископаемых широко применяются системы с открытым очистным пространством, в результате чего в массивах пород образуются полости значительных размеров. Это создает непосредственную опасность при производстве работ на участках, примыкающих к вы­работанным пространствам, и угрожает зданиям, сооружениям, угодиям, рас­положенным на дневной поверхности ...
