  • Shaletekk H Shale Oil Cold Extraction
  • 1Shaletekk HAfter 7 years of research and development we can finally present a viable and credible process/systemwhich will allow cost-effective cold and environmentally friendly extraction of shale oil from the substrate,At Naturetekk we are dedicated to the promotion and commercialisation of this process;Shaletekk M. Acknowledgement and thanks to the Jordanian Government bodies and companies:The Higher Councilfor Science and TechnologyYarmouk University The NaturalResources AuthorityJordan PetroleumRefinery CompanyJordan University ofScience and TechnologyExtracting oil from oil shale is more complex thanconventional oil recovery.Hydrocarbons in oil shale are present in the form ofsolid, bituminous materials and hence cannot bepumped directly out of the geologic reservoir. The rockmust be heated to a high temperature, and the resultantliquid must be separated and collected. The heatingprocess is called retorting.Surface mining can recover much higher percentages ofin-place resources. The thickness of oil shale deposits,the amount of overburden and the presence ofsubsurface water can make surface mining difficult.Shale oil extraction is an industrial process forunconventional oil production. This process convertskerogen in oil shale into shale oil by pyrolysis,hydrogenation or thermal dissolution. The resultant shaleoil is used as fuel oil or upgraded to meet refineryfeedstock specifications by adding hydrogen andremoving sulphur and nitrogen impurities.As of 2010 shale oil extraction is in operation withinEstonia, Brazil, and China. In 2008 their industriesproduced about 930,000 metric tonnes (17,700 barrelsper day) of shale oil. Australia, USA and Canada havetested shale oil extraction techniques via demonstrationprojects and are planning commercial implementation:Morocco and Jordan have announced their intent to dothe same. Only four processes are in commercial use:Kiviter, Galoter, Fushun and Petrosix.Conventional ProcessesAmerica’s oil shale reserves will potentially produceat least 1.5 trillion barrels of oil – approximately fivetimes the reserves of Saudi Arabia. Nobody isproducing commercial quantities of oil from thesevast deposits.Obviously, there are some very real obstacles to oilproduction from shale. “Oil shale is the fuel of thefuture, and always will be,” is a popular saying inWestern Colorado.

The current state of the art in mining – bothroom-and-pillar and surface techniques, such as open pitmining – appears to be able to meet the requirements forthe commercial development of oil shale.Surface retorting involves crushing the mined oil shale andthen retorting it at about 900 to 1,000°F. The vessel in whichthis heating occurs is called a retort. The hot shale oilleaving the retort is not stable and must be sent directly toan upgrading plant for catalytic processing with hydrogento remove impurities and produce a stable product.This stable shale oil can be used as a refinery feedstockand should compete favourably with sweet, light crude oil.An oil shale plant operating on a commercial scale – that is,producing a minimum of 50,000 barrels per day – wouldneed to incorporate multiple retorts. As the residence timeof oil shale in the hot zone of a retort is nearly a half hour, aretort designed to produce 50,000 barrels of shale oil perday would need to be sized to contain more than 1,500tons of oil shale, which is well beyond the state-of-the-art.In-Situ RetortingIn-situ retorting entails heating oil shale in place, extractingthe liquid from the ground and transporting it to anupgrading facility.The mainstream methods involved burning a portion of theoil shale underground to produce the heat needed forretorting the remaining oil shale. This was unsuccessful,encountering serious problems in maintaining andcontrolling the underground combustion process andavoiding subsurface pollution.
  • 3Environmental Issues of shale oil extractionThermally Conductive In-Situ ConversionA volume of shale is heated by electric heaters placed invertical holes drilled through the entire thickness (morethan a thousand feet) of a section of oil shale. To obtaineven heating over a reasonable time frame, between 15and 25 heating holes will be drilled per acre. After heatingfor two to three years, the targeted volume of the depositwill reach a temperature of between 650 and 700°F. Thisvery slow heating to a relatively low temperature(compared with the plus-900 degrees F temperaturescommon in surface retorting) is sufficient to cause thechemical and physical changes required to release oilfrom the shale. On an energy basis, about two-thirds ofthe released product is liquid and one third is a gas similarin composition to natural gas. The released product isgathered in collection wells positioned within the heatedzone.As part of site preparation, Shell’s current plan is to useground-freezing technology to establish an undergroundbarrier around the perimeter of the extraction zone.A “freeze wall” would be created by circulating arefrigerated fluid through a series of wells drilled aroundthe extraction zone. In addition to preventing groundwaterfrom entering the extraction zone, the freeze wall isintended to keep hydrocarbons and other productsgenerated by retorting, from leaving the project perimeterduring ground heating, product extraction, and postextraction ground cooling. The site preparation stage alsoinvolves the construction of power plants and powertransmission lines needed to supply electricity to theunderground heaters.Post-production cleanup involves steam flushing to removeremaining mobile hydrocarbons, ground cooling, removingthe freeze wall, and site reclamation.Shell plans to use ground-freezing technology to controlgroundwater during production. Ground-freezingtechnology is a well-established method for controllinggroundwater during construction and mining operations.Multi-kilometer barriers have been constructed andsustained for years.“The ICP process is clearly energy-intensive,as its driving force is the injection of heat intothe subsurface.”At the moment, Shell is not sure what the optimal size ofproduction zones ought to be. The issue here is how bigcan a freeze-wall be to become effective, freezing thegroundwater surrounding a shale deposit? The testprojects as you can see, were quite small. Shell doesn’tknow, or isn’t saying, what the optimum size is for each“pod” or “cell”.Nonetheless, applying ground-freezing to in-situconversion of oil shale requires resolving significanttechnical uncertainties to ensure that the frozenbarrier is structurally sound. Substantial uncertaintiesremain regarding the impact of in-situ retorting on thequality of groundwater. Retorting and removinghydrocarbons will change aquifer properties and will likelyresult in an increase in hydraulic conductivity. After theremoval of the freeze wall, such changes in aquiferproperties could result in the leaching and transport ofmineral salts and trace metals that are mixed with oil shaledeposits.

Chemical kineticsincludes investigations of how different experimentalconditions can influence the speed of a chemical reactionand yield information about the reactions mechanism andtransition states, as well as the construction ofmathematical models that can describe the characteristicsof a chemical reaction.It deals with the experimental determination of reactionrates from which rate laws and rate constants are derived.Relatively simple rate laws exist for zero-order reactions (forwhich reaction rates are independent of concentration),first-order reactions, and second-order reactions, and canbe derived for others. In consecutive reactions, the rate-determining step often determines the kinetics. Inconsecutive first-order reactions, a steady stateapproximation can simplify the rate law. The activationenergy for a reaction is experimentally determined throughthe Arrhenius equation and the Eyring equation. The mainfactors that influence the reaction rate include: the physicalstate of the reactants, the concentrations of the reactants,the temperature at which the reaction occurs, and whetheror not any catalysts are present in the reaction.The active catalyst in this process is a proprietaryBIO-SURFACTANT PRODUCING BACTERIA.Shale oil cold extraction processProcess based on the kinetics of hydrocarbon extraction from oil shaleusing bio-surfactant producing bacteria. energy conservation and management.
