    US oil shale reserves contain a vast carbon energy source which if produced in an economically feasible and environmentally safe manner - would provide part of the solution for future US energy needs. While no commercial production of oil shales currently occurs, in situ retorting is generally regarded as the most likely approach. I am doing comparative analysis of Oil Shale, coal (coal liquids), bitumen, brine & gas using NMR. Unfortunately, i have not had T1, T2 values of these materials measured at specific fields.

    Clear all plants and other debris off the bed. 2. Thoroughly wet the bed as described above. 3. Thoroughly loosen the soil using a digging fork or spading fork. If children are helping with bed prep, consider using hand trowels instead of large tools. 4. Rake the surface smooth and level and rake up the edges of the bed so that they are clearly. @article{osti_, title = {BX In Situ Oil Shale Project: design and objectives}, author = {Dougan, P.M.}, abstractNote = {In the central portion of the Piceance Creek Basin of nw.

The extensive oil shale reserves of the United States are now under development as an energy source. One of the approaches for extracting oil from shale is the so-called modified in-situ retort. The operation of such retorts for maximum yield requires an understanding of oil loss mechanisms so that operating strategies that minimize these.

An Assessment of Oil Shale Technologies its can be retorted, oil recoveries per acre affected are high, and relatively few surface facilities. The advantages of in situ processing include the following: (1) oil can be recovered from deep deposits of oil shale formation, (2) mining costs can be eliminated or minimized, (3) issues related to solid waste are eliminated, (4) shale oil can be extracted from leaner shale, for example, deposits containing less than 15 gallons of shale oil.

According to the top surface between the southern and northern Cretaceous strata of the Second Songhua River, the breaking distance is inferred to be m. The second event cut the Tertiary strata to break away about 20 m. introducing heated gases or liquids to the oil shale formation.

Two methods of in situ oil shale retorting have been tested. The “true” in situ method consists of fracturing, retorting, and recovering the products through the use of boreholes from the surface. about the nature of oil shale is followed by an evaluation of technologies for recov-ery of shale oil.

The economics and finances of establishing an industry of various sizes are analyzed. The fact that much of the best shale is located on Federal land is examined in light of the desire to increase use of the resources.

The conse. Oil Shale Ex-Situ Process - Leaching Study of Spent Shale 48 | Page The product of oil shale process contain oil, gas, water and spent shale (solid residue). A dry and wet basis weight percentage of the composition of this type of shale are shown in Table 2. El-Lajjun oil shale is part of South Tethyan oil shale-phosphorite giant belt 10].

During the formation of oil [shale, Jordan was located in an epicontinental sea [11]. Bioproductivity was enhanced by deep cold water rich in nutritants brought to the surface by upwelling currents 12] [13]. The deposition was influenced by syn[ -sedi. THE IN-SITU ADVANTAGE. Smaller footprint: The surface area required for the wellheads and central processing plant is very small relative to the size of the oil sands -situ facilities therefore have a much smaller footprint than surface mining operations.

In-situ plants require about 1/7th the land area of an equivalent-sized mining facility. The shale oil is first being mined and then be retorted and upgraded. The current process which known as in-situ retorting involves heating the oil shale while it is still underground followed by pumping the resulting liquid to the surface for further process as a source of oil.

The collected shale oil need to be upgraded to. The results demonstrated that continental oil shale needs to be heated for about 6–8 years to enable its conversion more than 90% under in situ retorting.

EIA/ARI World Shale Gas and Shale Oil Resource Assessment June, 9 Finally, shale gas and shale oil basins and formations that have very high clay content and/or have very high geologic complexity (e.g., thrusted and high stress) are assigned a high prospective area risk factor or are excluded from the resource assessment.

Subsequent, more. The retort vessel, a refractory lined carbon steel cylinder, is meters high with an inside diameter of 3.S meters. The oil shale is loaded from the top and a hinged grate at the bottom supports the oil shale bed.

After the processing has been completed, the grate is opened to discharge the spent shale. The following operating procedure is.

The present invention is directed to methods for extracting a kerogen-based product from subsurface (oil) shale formations, wherein such methods rely on fracturing and/or rubblizing portions of said formations so as to enhance their fluid permeability, and wherein such methods further rely on chemically modifying the shale-bound kerogen so as to render it mobile.

Technologies for oil shale production include surface and in-situ retorting. This study focusses on in-situ oil shale production methodologies. The process of heating oil shale to the pyrolysis temperature can be achieved by direct or indirect heating.

Direct heating geometries include the Shell in-situ conversion process (ICP) using downhole. Crude shale oil can be obtained from either in situ (underground) or ex situ (aboveground) extraction processes.

While in an ex situ processing the shale has to be mined and then surface retorted; in the in situ process, the deposit is fractured and then retorted underground (Lee, ). a) Ex situ.

In Situ Methods used in the Oil Sands In situ methods are used to recover bitumen that lies too deep beneath the surface for mining (about 80% of the oil sands in Alberta). The success of in situ methods depends on the resolution of two major issues: 1) reducing the viscosity of bitumen so that it will flow, and 2) recovering the bitumen from deep within the earth (OSDC c).

Abstract. Atmospheric pressure fluidized bed technology offers many processing advantages for retorting oil shale. The one advantage which has been most studied and emphasized is that oil yield, as compared to Fischer assay, is increased. Results of this in situ combustion experiment, conducted by the Bureau of Mines near Rock Springs, Wyoming to produce shale oil from oil shale, indicate that a combustion zone can be established in a fractured oil shale body by using air injection and a propane burner.

During the 6-week period that combustion was maintained, 8, gallons [email protected]{osti_, title = {Environmental research on a modified in situ oil shale task process.

facility at Logan Wash, Colorado. More specifically, the Task Force obtained .Site Preparation. Since the success of any in-situ combustion oil recovery experiment in oil shale depends directly on the ability of air, combustion gases, and produced oil to move through the shale formation, produced oil to move through the shale formation, the first part of the site preparation consisted of an intensive fracturing program.
