Sentences with word «kerogen»

To understand these pores, the research team started with samples of isolated shale kerogen, an organic matter that stores the majority of hydrocarbons such as natural gas in shales.

In both sequences, he found thin, discontinuous streaks of kerogen, a waxy precursor to fossil fuels formed from organic matter and commonly found in much younger shales that are known oil producers.

Pseudo-petroleum sources like kerogen are an ERoI fallacy, hyped into «trillions of barrels» by wild speculators.

The necessary knowledge, however, for converting kerogen (an oil precursor) into oil and recovering that oil remains commercially problematic.

It must also be emphasized that kerogen (seen as America's Saudi Arabia by non-geologists) may never break even, commercially.

To peer inside the kerogen, they used small - angle neutron scattering, shooting a beam of subatomic neutrons through a substance and collecting information on the neutrons» behavior to determine the properties of the pores.

Rasmussen, who reports his results in the current issue of Geology, believes the abundance and extent of the kerogen in the shales indicates the ocean was already teeming with enough single - celled life 3.25 billion years ago to support widespread oil generation.

However, all of the carbonate, carbon in kerogen and coal and sulphates and oxidised Fe are transformed with silica into reduced silicate forms and oxidised gases CO2 and SO2, the free energy changes result in degraded heat.

If you add up the mass of carbon as carbonate (eglimestone) and carbon (kerogen / coal / oil / gas) in the crust it comes to ca. 98 * 10 ^ 21g.

That is the kerogen - quality material, that if processed will take so much energy that it will act as a multiplier to CO2 emissions.

Oil shale is a fine - grained sedimentary rock containing a solid material (kerogen) that converts to liquid oil when heated.

To satisfy the increase in world liquids demand in the Reference case, liquids production increases by 28.3 million barrels per day from 2010 to 2040, including the production of both petroleum (crude oil and lease condensate, natural gas plant [NGPL], bitumen, extra-heavy oil, and refinery gains), and other liquid fuels (coal - to - liquids [CTL], gas - to - liquids [GTL], biofuels, and kerogen).

The Medieval Warm Period in AD 980-1250 is the most distinctive climate period in the whole sediment sequence identified by changes in sediment colour, X-ray density, varve thickness, LOI, as well as the isotopic composition of hydrogen in kerogen.

This time around, Shell's ambitious plan involves actually heating the earth itself, which turns the kerogen — a chemical compound embedded in the rock — into extractable oil and gas.
