Fossil Fuels - Kerogen ❖The most commonly utilized scheme for classifying organic matter in sediments is based on the relative abundance of elemental carbon, oxygen, and hydrogen plotted graphically as the H/C and O/C ratio on a so called Van Krevelen diagram. Organic carbon in the form of kerogen is the remnant of ancient life preserved in sedimentary rocks, after degradation by bacterial and chemical processes, and further modified by temperature, pressure, and time. The latter step, called thermal maturation, is a function of burial history (depth) and proximity to heat sources. Maturation provides the chemical reactions needed to give us gas, oil, bitumen, pyrobitumen, and graphite (pure carbon) that we find while drilling wells for petroleum.

Oil/gas : Resources/Reserves/Recoverable ❖RESOURCES IN PLACE : A 'Mineral Resource' is a concentration or occurrence of material of intrinsic economic interest in or on the earth's crust, a proportion of which are in such such form, quality and quantity having reasonable prospects for eventual economic extraction, forming a viable RESERVE. ❖RECOVERABLE RESERVES : A term used in natural resource industries to describe the amount of resources identified in a reserve that is technologically or economically feasible to extract. A new reserve can be discovered, but if the resource cannot be extracted by any known technological methods, then it would not be considered part of recoverable reserves. Recoverable reserves is also often called proved reserves. ❖ Oil and gas % of Resources recovered Depends on Tech used at the time. ❖ As little as 5% of reserve may be ECONOMICALLY recoverable. ❖ Recoverability depends on how locked in (tight) the hydrocarbon is to the strata bearing it. ❖ Exploit usually starts at 40% or less, then more tech lifts to 60% or more.

WORLD CONSUMPTION OF FUELS 2016 Hydro Nuclear Wind,Solar etc 5% 5% 26 Billion 2% Barrels of Oil equivalent Coal 28% Natural Gas 25% Oil 35% World consumption = 11,366 M.t.o.e, (gas 2,741). UK consumption = 213 M.tonnes oil equivalent 1 toe = 7.14 Barrels. = 32 Billion barrels of oil/yr. 13/11/2019 Fracking Update - 2019 No. 5 4. Energy…Joules,KWh,Calories,BTUs. ❖Definition. A Newton (N) is the S.I. unit of measure for force. One Newton is equal to 1 kilogram meter per second squared. In plain English, 1 Newton of force is the force required to accelerate an object with a mass of 1 kilogram 1 meter per second per second. ❖ The Joule, symbol J, is a derived unit of energy in the International System of Units. It is equal to the energy transferred (or work done) to an object when a force of one newton acts on that object in the direction of its motion through a distance of one metre (1 newton metre or N. m) ❖ 1 KiloWattHour (KWh, SI unit) equates to 3.6 Mega Joules. ❖ 1 British Thermal Unit (BTU, non SI unit) equates to 1,055 Joules. It is the energy required to raise 1 pint of water through 1 degree Fahrenheit. A 4 inch wooden match when burnt = 1 BTU. ❖ 1 KWH (SI unit) equates to 3,412 BTU. ❖ The therm (symbol thm) is a non-SI unit of heat energy equal to 100,000 (BTU). It is approximately the energy equivalent of burning 100 cubic feet (2.83 cubic metres) – often referred to as 1 CCF – of natural gas. ❖1 Calorie measures energy to raise 1 Gram of water by 1oc. 1 Calorie = 4.2 Joules. Note : 1 NUTRITIONAL CALORIE (NC) = 1,000 Calories = 4,200 Joules. 2,000 NC = 2.33 KWh). ❖Electrically, 1 joule = 1 Coulomb – Volt. A coulomb is an S.I unit of 1amp flowing for 1 Second. A joule therefore equates to 1 amp flowing for 1 second at 1 Volt. ❖Voltage (Volt) electric potential along a wire when an electric current of one ampere dissipates one watt (W) of power (W = J/s). A volt can be stated in SI base units as 1 V = 1 kg m2 s−3 A−1 (one kilogram meter squared per second cubed per ampere). 13/11/2019 Fracking Update - 2019 No. 6 5. Energy Content of fuels ❖The most interchangeable unit of energy is the KiloWatt-hour (KWh). As at November 2019, one KWh costs around 13p from your electricity supplier. 1 KiloWatt is the rate of energy consumption.

We are Carbon weevils. ❖There are no natural “gushers” any more. ❖Since 1948 we have used low pressure fracking to enhance recovery. ❖Re-injection of water (Sea water often used). Recovery Improves. ❖Saudi Arabia = biggest concentration of NC fuels. Source : Prof. Peter Styles presentation 2015. ❖Surveys have identified 80% of the conventional resources, reckoned to be around 4 Trillion Barrels of oil equivalent. We have extracted over 50% of those viable resources now. ❖There is no estimate of Worldwide Non-conventional fossil fuels, we are on a hunt! ❖Non-conventional fuels often require extreme recovery techniques in very hostile places, eg 4 miles below the sea floor or inside the arctic circle. ❖Non conventional sources need oil price over $80/barrel to justify exploration and recovery.
