Sir What is 2^-infinity? Is it 2^0 =1...???
Hello sir...just wanted to thank u for ur awesome course and awesome discussions. Hatts of for ur dedication, committment and PUNCTUALITY

  7. lythr On August 1, 2018, the Central government approved a far-reaching policy that allows private and government players to explore and exploit unconventional hydrocarbons (including shale gas) in contract areas that were primarily allocated for extracting conventional hydrocarbons. iovs arieae m shale gas is trapped under low permeable rocks. Therefore, a mixture of 'pressurised water, chemicals, and sand' (shale fluid) is required to break low permeable rocks in order to unlock the shale gas reserves. The process requires around 5 to 9 million litres of water per extraction activity, posing a daunting challenge to India's fresh water resources. cause pollution due to the disposal of flowback (produced) water UBHODEEP

  8. Environment Impact Assessment (EIA) process. The EIA process, however, does not differentiate between conventional and unconventional hydrocarbons Ministry of Environment, Forest and Climate Change (MoEFCC), which generally releases sector-specific manual for environment clearance, is yet to come out with a manual specific to fracking activities. Despite acknowledging the enormity of water requirement for fracking activities, the guideline fails to give a general estimate of water requirement per unit of shale gas over the lifetime of a shale well. A recent study from Duke University observes that from 2011 through 2016, the water use per well in the US. increased up to 770% resulting in some shale wells consuming up to 42 million litres of water per well UBHODEEP

  9. The study further conveys that over a period of time, the usage of water dramatically increases for extracting the same amount of shale gas from a wel The importance of clarity in water usage and the place of shale gas extraction in India is linked directly with water requirements of priority sectors like agriculture Shale rocks are usually adjacent to rocks containing useable/ drinking water known as 'aquifers'. As noted by U.S. Environmental Protection Agency in 2017, while fracking, the shale fluid could possibly penetrate aquifers leading to methane poisoning of groundwater used for drinking and irrigational purposes.

  10. Studies- such contamination can be controlled, if not avoided, provided a project proponent maintains a distance of 600 m between the aquifers and shale gas fracture zones guideline states that a project proponent must "design and construct wells with proper barriers to isolate and protect groundwater", but misses out on broadly describing the nature or properties of a barrier surface, knovie pending on the local geology f surface, known as 'flowback water. When shale fluid is injected underground at high pressure to fracture the rock, 5.50% (depending on the local geology) of the fluid returns to the fracture the Return flows continue as oil and gas is pumped from the well.

  11. As a first step, a sector-specific EIA manual on exploration and production of unconventional hydrocarbon resources may be a good idea. UBHODEEP
