Russian scientists have proposed using depleted oil fields as storage facilities for greenhouse gases. This was reported by the press service of Moscow State University.
In recent years, governments of developed countries have decided to reduce their carbon dioxide emissions as it has a greenhouse effect on planet Earth and contributes to climate warming. In this regard, scientists and engineers are trying to replace many traditional technologies with “carbon-free” technologies, in which carbon dioxide is not emitted and ideally absorbed. In particular, greenhouse gases can be chemically bound or otherwise embedded in certain minerals.
Moscow State University experts and colleagues evaluated the effectiveness of CCUS carbon capture technology, which involves pumping emissions from industrial enterprises underground. Based on data from Gazpromneft STC, the authors calculated efficiency indicators for the use of reservoirs formed under various sedimentation conditions. This is a difficult, multi-parameter scientific task that requires combining knowledge in hydromechanics and geophysics.
“Estimating the amount of carbon dioxide that can be safely injected into a reservoir requires research at the intersection of fluids and gas mechanics, solid mechanics, geology and geochemistry. The various operating modes of wells used for CO2 injection, the physico-chemical interactions between fluids and rock, and varying voltages. -It is necessary to calculate three-dimensional multiphase flows of liquids and gases in a heterogeneous geological environment, taking into account the strain state of the porous medium, ”said one of the study participants, Corresponding Member of the Russian Academy of Sciences Andrey Afanasiev.
As a result, it was possible to obtain estimates of the capacity of ancient deposits in Western Siberia, as well as to prove why sedimentation barrier conditions have the greatest possibilities for the effective removal of millions of tons of carbon dioxide. The authors hope their work will help reduce global warming in the future.
