Example: "kerogen undergoes successive transformations concomitant with a gradual increase."

Enchanced oil recovery(EOR)
noun
is the extraction of crude oil from an oil field that cannot be extracted otherwise. This method increases the productivity of oil wells.
Example: "Shale formations have great potential for both EOR and CO2 sequestration."

Mineral composition
noun
is a fundamental feature that affects the properties and functions of soil through physical, chemical and biological interactions. Minerals divided into 7 groups by their chemical formulas.
Example: "The mineral composition of rocks does not affect the size of the formed pores, but in some cases it controls the amount of formed hydrocarbon compounds and the composition of the liquid products."

Rock fabric
noun
it describes the spatial and geometric configuration of all the elements that make it up in a sample.
Example: "kerogen exists as aggregates within the rock fabric, resulting in challenges in understanding its unique properties."

Shale
noun
is a fine-grained, clastic sedimentary rock formed from mud that is a mix of flakes of clay minerals
Example: "Thermal treatment (artificial thermal maturation) of the BF organic-rich shale leads to the development and the evolution of organic porosity."

Total organic carbon (TOC)
noun
is the main measurement used for estimating the quality and productivity of a source rock. The source rock - usually an organic rich shale - contains various carbon compounds such as kerogen, bitumen, oil and gas.
Example: "Organic matter in shaly lignites characterised by high TOC and thermally mature Type III kerogen."

Vitrinite reflectance
noun
is a measure of the percentage of incident light reflected from the surface of vitrinite particles in a sedimentary rock. It is referred to as %Ro. Results are often presented as a mean Ro value based on all vitrinite particles measured in an individual sample.
Example: "Vitrinite reflectance measured on whole rock is often considered to be more reliable because autochthonous vitrinite grains are better identified in their natural setting."
