The effects of calcite and montmorillonite on oil cracking in confined pyrolysis experiments
TLDR
In this article, three sets of pyrolysis experiments were performed for oil alone, oil plus montmorillonite and oil plus calcite at two heating rates of 2.5 and 20.5°C/h in confined systems (gold capsules).About:

Giant gas discovery in the Precambrian deeply buried reservoirs in the Sichuan Basin, China: Implications for gas exploration in old cratonic basins
TL;DR: An estimated trillions of cubic meters of natural gas have recently been discovered in the Sinian dolomite reservoirs in the Sichuan Basin, China as mentioned in this paper, where 20-26m thick reservoirs were found in deep structural-lithologic traps of 5000-5500m deep.

Towards an understanding of the role of clay minerals in crude oil formation, migration and accumulation
TL;DR: A review of the role of clay minerals in crude oil formation, migration and accumulation can be found in this article, where the authors present a detailed analysis of the chemical interactions and reaction mechanisms between clay minerals and crude oil.

Discovery of the lower Cambrian high-quality source rocks and deep oil and gas exploration potential in the Tarim Basin, China
TL;DR: In this paper, a set of high-quality source rocks were developed within the lower Cambrian Yuertusi Formation (J1y), at the base of the lower-Cambrian dolomites.

Alteration and multi-stage accumulation of oil and gas in the Ordovician of the Tabei Uplift, Tarim Basin, NW China: Implications for genetic origin of the diverse hydrocarbons
TL;DR: In the Tabei Uplift of the Tarim Basin, there were three main periods of hydrocarbon accumulation in the late Caledonian stage, the late Hercynian stage and the late Himalayan stage as mentioned in this paper.

Evaluation of a Simple Model of Vitrinite Reflectance Based on Chemical Kinetics
Jerry J. Sweeney,Alan K. Burnham +1 more
TL;DR: In this article, a simplified version of a vitrinite maturation model, called EASY%R[o], was presented, which uses an Arrhenius first-order parallel-reaction approach with a distribution of activation energies.

Experiments on the role of water in petroleum formation
TL;DR: The role of water in the formation of bitumen is investigated in this paper, where the authors evaluate the role of liquid water in bitumen formation and demonstrate that it is essential to the generation of an expelled saturate-enriched oil that is similar to natural crude oil.
Journal ArticleDOI
Experimental simulation in a confined system and kinetic modelling of kerogen and oil cracking
TL;DR: In this article, the authors experimentally simulate both kerogen and oil cracking in a closed pyrolysis system and then, to model the kinetic scheme, they show that a unique kinetic scheme can be used for secondary cracking reactions either when oil is pyrolysed alone or when bitumen is first generated during kerogen pyrolynsis.

Mathematical modeling of stable carbon isotope ratios in natural gases
TL;DR: In this article, a new approach is presented for mathematical modeling of stable carbon isotope ratios in hydrocarbon gases based on both theoretical and experimental data. The kinetic model uses a set of parallel first-order gas generation reactions in which the relative cracking rates of isotopically substituted (k∗) and unsubstituted (k) bonds are represented by the equation k∗/k=(A f ∗/A f ) exp(−ΔEa/RT), where R is the gas constant and T is temperature.

An investigation of the in-reservoir conversion of oil to gas: compositional and kinetic findings from closed-system programmed-temperature pyrolysis
TL;DR: In this paper, the same successive compositional changes occurred in each case: increase in the total yield of GC-detectable compounds, significant gas (C1C4), generation accompanied by a decrease in yield of heavy components, aromatisation and attainment of maximum gas yield and finally a cracking of the C2+ gas components.
