A wrench fault, also known as strike-slip fault, is a type of fault where the movement of blocks is primarily horizontal and is parallel to the strike of the fault plane. These can be either : These faults often form in transform plate boundaries or in strike-slip tectonic regimes and can be associated with complex […]

Coal can act as a source rock for the generation f liquid hydrocarbons. The production of liquid hydrocarbons from coal is similar to that of type III kerogen, reflecting the origin of the organic matter in coal and type III kerogen, primarily from hydrogen -poor (lipid-poor) and oxygen rock vascular plants. Petroleum generation during coalification

The Rock-Eval pyrolysis is a widely used geochemical technique in petroleum exploration and organic geochemistry. It provides valuable information on the quantity, type and thermal maturity of organic matter in sedimentary rocks, helping geologists asses hydrocarbon generation potential. Principles of Rock-Eval Pyrolysis Rock Eval pyrolysis involves heating a rock sample in an inert atmosphere and

Gas Chromatography is a chromatographic technique used to separate volatile compounds and those which can vaporized by heat. If a mixture of compounds is analysed using GC system, each compound can be separated and quantified. It is useful and important because of following – Components of gas chromatography This is the overall main components of

All the above terms may looks similar but are different. Let’s deep dive into them . Oil Shale Oil shale is a type of sedimentary rock that is rich in kerogen. Kerogen is a part of rock that breaks down and release hydrocarbon heated. Oil shale can be thought of as a precursor to oil

There are several types of geological formations that trap naturally occurring energy resource. They are categorized as either ‘conventional’ or ‘unconventional’ resources. Conventional Unconventional Conventional oil and gas is trapped in naturally porous reservoir formations that are capped with impermeable rock strata. When intercepted by a well, oil and gas is able to move to

In the distillation process, petroleum is separated into different molecular groups : C1– C4 Gas C5– C10 Gasoline C11– C13 Kerosine C14– C18 Diesel fuel (light gas oil) C19– C25 Heavy gas oil C26– C40 Lubricating oil > C40 Residuum Natural Gas : Natural gas usually consists mostly of methane (CH4) but may contain variable

Petroleum and natural gas are mixtures of hydrocarbons. On average, they consist of 85% C, 13% H and 2% N,S and (all weight %). The main components of natural hydrocarbons belongs to three groups : Paraffins : or n-alkanes with general formula CnH2n-2. for n = 1 to 4 these are gases, from n =
