Sand control refers to managing/minimizing sand and fine production during petroleum production.Sand and fine produced with oil and gas can cause erosion and wear of production facilities/equipments, resulting in production downtime, expensive repairs, and potentially loss of containment (serious safety risk).

Flowback procedures for wells producing from sub-normally or normally pressured reservoirs are usually straightforward and non-technical due to the short flowing periods that are inherent with low pressure wells. Over-pressured formations can naturally flow for several months and even years. However, uncontrolled procedures can potentially affect the well productivity and its profitability

• The most reliable studies suggest that the EROI for oil shale falls between 1:1 and 2:1 when self-energy is counted as a cost. • Self-energy is energy released by the oil shale conversion process that is used to power that operation. • This places the EROI for oil shale considerably below the EROI of about 20:1 for

Oil shale is used as fuel for electricity generation and shale oil pro- duction. For power generation, grain size of oil shale has to be 0–25 mm or 0–300 mm of lower heat value Qw = 8.4–8.6 MJ/kg, depending on the mode of production. Grain size for oil production must be in the range 25–125 mm and lower heat value Qw = 11.3–11.6 MJ/kg.

API Frac Sand Standards and Microproppants. Recently, smaller grains of sand are in demand in the oil and gas markets. While fracking processes started with coarser grains of sand, the market is trending toward finer mesh size silica grains. At first, fracking used silica sand with mesh such as 16-30, 20-40, and 30-50.

Severe crushing and proppant flowback are the major topics of discussion in this paper. These factors have been found to cause drastic reductions in fracture conductivity, particularly near the wellbore. 5,6 In many cases, the damage has occurred as a result of flowing the well too hard in an attempt to produce more oil or gas.

approximately 8.3-8.4 MJ/kg (conventional oil shale). That fuel contains carbonate minerals (mineral CO2 content up to 20%) resulting in high specific emission of CO2 (in a range of 0.95–1.12 t/MWhe depending on combustion technology) due to dissociation of carbonate minerals. For minimizing CO2 emission, oil shale of higher quality should be

Since the fines in the crushed shale which may be agglomerated may vary from 6 to 8% up to 25to 50% by weight of the total raw shale feed stream, the effective agglomeration and distillation of the fines contributes importantly to the total recovery of oil from the overall retorting of the entire tonnage of shale that is mined.

Extracting and processing shale oil is an expensive and difficult process. Coal, petroleum, and natural gas are less expensive to extract. Australia, Brazil, Switzerland, Sweden, Spain, and South Africa began mining oil shale in the 19th and 20th centuries, but they all stopped production by the 1960s. The U.S. ceased production in the early 1980s.

During oil shale retorting the shale is heated in the absence of oxygen to the temperature (350–400 °C) at which kerogen is decomposed or pyrolysed into gas, condensable oil and solid residue.

Studies in shale reservoirs indicate that aggressive or unmanaged pressure drawdown can have a number of detrimental consequences on flow capacity, EURs and well economics. An example is hydraulic fracture conductivity impairment caused by proppant crushing, embedment and fines migration.

Oil shale can be mined using one of two methods: underground mining, most likely using the room-and-pillar method, or surface mining. In general, surface mining is the most efficient approach for mining oil shale. Room-and-pillar mining can recover about 60 percent of the oil shale in place for seams that are no more than about a

Shale is the most common sedimentary rock, accounting for about 70 percent of the rock in the Earth''s crust. Shale is a fine-grained rock made from compacted mud and clay. The defining characteristic of shale is its ability to break into layers or fissility. Black and gray shale are common, but the rock can occur in any color.
