The physical simulation of heavy oil catalytic aquathermolysis with different chemical compositions from deposits located in the Tatarstan Republic, Russia (Ekaterinovsky oil, B2 type, and Olimpiadovsky A1 type), was designed. processes were conducted at a temperature 300 °C presence rock-forming additive - kaolin (the content montmorillonite 44%), catalysts composed transition metal (Fe, Co, Cu) carboxylates. environment mixture carbon dioxide water vapor. distinctive features...

In this study, the specific features of Ashal'cha heavy oil conversion were revealed. The hydrothermal catalytic experiments carried out in a CO2 environment and presence oil-soluble carboxylate metals such as Fe, Co, Cu at temperature 300 °C. results have shown that catalyst minerals reservoir rocks significant impact on transformation behavior group, structural hydrocarbon compositions oil. most changes composition established after treatment rock-forming additive, clay mineral (kaolin),...

This study is intended to reveal the impact of hydrothermal treatments at temperatures 200, 250, 300, and 350 °C on organic matter (OM) low-permeable rocks two different lithofacies types (carbonate carbonate–siliceous rocks) from Domanic deposits Upper Devonian Tatarstan. Autoclave experiments were carried out in a carbon dioxide environment. The content OM yield rock extracts, as well stability kerogen structures influences, evaluated. saturated hydrocarbons extracts increases after...

Character of conversion organic matter from Domanic rocks Pervomaiskoye field (Tatarstan) Semiluki horizon upper Devonian deposits in the hydrothermal-catalytic system at temperature 300 °C carbon dioxide medium was studied with application complex oil-soluble precursors catalysts containing Fe, Co, and Cu. In presence complex, content extract increases, which hydrocarbon fractions, saturated aromatic hydrocarbons, increases 1.5 times, while resins decreases by two times. As result kerogen...

The features of the oil-bearing capacity productive strata Permian deposits in interval 117.5-188.6 m along section individual wells Ashal’cha field heavy superviscous oil (Tatarstan) were revealed depending on content, composition, and thermal effects organic matter (OM) oxidation rocks. It is shown that rocks are very heterogeneous their mineral composition content both free hydrocarbons by extraction with solvents insoluble OM closely associated rock. total varies from 1.72 to 9.12%....

A series of experiments has been carried out on the thermolysis heavy oil using 2.5–10.0% light hydrocarbon naphtha additive vacuum gasoil prepared from conventional oil. It shown that employment increases conversion oil, avoids coke formation in products as compared to basic process without additive, and does not prevent decrease viscosity during thermolysis. revealed example Ashal’chinskoe deposit (Russia) with addition gives a liquid product yield higher than 97% less 80 mm2/s.

The byproduct of ethylene tar has a high content mono-, bi-, and polycyclic aromatic compounds, as well cycloalkenes, including cycloalkenes. This paper evaluates the prospects using an additive in visbreaking process vacuum residue. A series experiments on residue with additives various refinery streams were performed laboratory flow reactor. As result comparative study composition products by different methods, it was shown that use compared kerosene, light cycle oil, heavy oil allows...

Thermolysis experiments of heavy oil have been carried out in flow reactor with the addition 2.5–5.0% kerosene fraction hydrocracking vacuum gas prepared from conventional oil. It has shown that additive increases degree conversion, restricts coke formation products thermolysis as compared to process without additive, and provides a decrease viscosity products. conditions reactor, which give liquid more than 97% yield less 75 mm2/s, determined case Ashal’ chinskoe deposit.

The hydrocarbon compositions of shale oils, generated from two different lithological–facial Domanic deposits the Tatarstan Republic (Russia), were studied under hydrothermal impact with 30% water addition in a 350 °С and CO2 environment. samples extracted carbonate–siliceous rocks Semiluky–Mendym Berezovskaya area, carbonate Dankovo–Lebedyan horizon Zelenogorskaya area Romashkino oil field. distinctive features are composition content organic matter (OM), its thermal stability, as well...

In laboratory model experiments were identified features of hydrothermal transformation heavy oil and organic matter productivity carbonate rocks from Bashkirian stage deposits the Middle-Carboniferous Tatarstan territories. Experiments conducted at temperature 360 °C in hydrogen environment presence aqueous phase. The impact factors on leads to decrease content insoluble OM - kerogen increase free hydrocarbons. With saturated aromatic hydrocarbons, resin-asphaltene components decreases....

Changes in the composition and properties of heavy oil during thermolysis temperature range 250–410°С presence molten sodium without hydrogen has been studied. Addition results decrease sulfur content products by factor 1.5 at 250°С a more than two-fold 350°С higher. A is recorded only less 10%. Viscosity density with almost do not differ correspond to nearly 90 mm2/s 20°С API gravity higher 26, respectively. Effect on quantitative distribution components (hydrocarbons, resins, asphaltenes)...

The oil generating potential of Domanic rocks from Dankov–Lebedyan horizon the Zelenogorsk area Romashkino field was evaluated by Rock-Eval pyrolysis technique. result given method depends on content, composition, and thermal stability organic matter in rocks. During hydrothermal processes, distinctive conversion behavior at temperatures 200°С, 250°С, 300°С, 350°С CO2 environment revealed. yield obtained aquathermolysis products their quality were evaluated. results studies suggest that...
