“…In addition, we gave the abiogenic advocates a hint that the spin magnetic effects can also explain the narrow range of geological time over which they claim all worlds' significant reservoirs to have formed. The material reported herein contradicts the chemical kinetic modeling which is extensively employed by the biogenic theory's advocates [66,67]. This contradiction is primarily attributed to the basin kinetic models that factor in only reservoir temperature and geological time, in which case the effect of discrete geomagnetic fields on the petroleum generation kinetics is disregarded.…”

“…The reservoir fluids move from the highest pressure areas to the lowest ones along the path of least resistance. Such pathways can be vertical disjunctive faults in the sedimentary cover [63][64][65][66]. Following this, the zones near faults may be the source of discrete geomagnetic fields, which in turn may influence the petroleum generation processes due to the spin magnetic effects during the transformation of organic matter.…”

This review paper presents controversial issues on the formation of hydrocarbon deposits. We look into the geological contradictions of the abiogenic and biogenic theories of petroleum origin, indicating the connection between hydrocarbon deposits and disjunctive dislocations, as well as present disputes about the geological period over which hydrocarbon deposits have been formed. We further overviewed the radical chain mechanism of hydrocarbon generation from organic matter as proposed by Prof. Nesterov. It is noted that the petroleum generation process in reservoir conditions occurs almost instantly in the presence of discrete geomagnetic fields and does not require a long geological time. This is explained by spin magnetic effects (spin catalysis, magnetic isotope properties). We briefly highlight the effect of magnetic fields on chemical reactions involving organic compounds and the use of magnetic fields to enhance oil recovery. We also present the leading causes of discrete magnetic fields in the sedimentary cover: Earth’s geomagnetic reversals, generation of ferromagnetic minerals in oil deposits, electromechanical effects of rock friction near faults, and intermixing of reservoir waters with different mineralization (spontaneous ion polarization). Based on the material reported, we conclude that the radical chain mechanism of petroleum generation processes explains some contradictions of the abiogenic and biogenic theories of petroleum origin. Elaborating this research area has excellent prospects for developing new criteria for hydrocarbon prospecting and devising innovative methods to enhance the oil recovery for shale oil production.

“…The unconventional hydrocarbon source rock, however, is the same as the reservoir in which the organic matter was buried and cooked at high temperature and high pressure over a very long time. 3 The challenge in evaluating unconventional reservoirs is that for all petrophysical calculations of the reservoir properties, the kerogen or organic matter properties should be included in all of the calculations. 4 This organic matter goes through stages of development from organic matter to finally oil or gas.…”

Effect of Silica Nanoparticles on Polymer Adsorption Reduction on Marcellus Shale

et al. 2021

Polymers play a major role in developing rheology of fracturing fluids for multistage hydraulic fracturing horizontal wells in unconventional reservoirs. Reducing the amount of polymer adsorbed in the shale formation is essential to maintain the polymer efficiency. In this study, the ability of silica nanoparticles to minimize polymer adsorption in Marcellus shale formation at reservoir temperature was investigated. Partially hydrolyzed polyacrylamide polymers of varying molecular weights (1–12 MD), salinities (2500–50,000 ppm), polymer concentrations (100–2000 ppm), and silica nanoparticle concentrations (0.01–0.1 w/w) were used in the static adsorption experiments. Adsorption of the polymer in the Marcellus shale samples was contrasted with and without the silica nanoparticles at a Marcellus formation reservoir temperature of 65 °C, showing a significant polymer adsorption reduction of up to 50%. The adsorption and adsorption reduction were more sensitive to the variation of the polymer concentration than to the variation of the salinity within the tested conditions. The highest adsorptions were reported at the higher molecular weight of 10–12 MD. In addition, silica nanoparticles significantly improved polymer rheology at elevated temperatures. The results indicate that nanoparticles can play a significant role in reducing polymer adsorption in the fracturing fluid and improve its rheological properties and its efficiency, which will reduce the number of issues caused by the polymers in the fracturing fluid and making it more cost effective.
