This article is a brief defense of a previous article by the same author (Babu and Odeh, 1989) which advocated his methodologies for predicting long-term productivity of oil and gas wells. His former paper discussed a complex general solution and a simpler approximate solution for calculating the...
The increasing trend of gas productivity index per meter with the increase of reservoir permeability is first fast and then slow. When the reservoir permeability is greater than 1.2 mD, the increment of gas productivity index per meter (MGPI) decreases. When the length of horizo...
the chemical reaction of pharmaceutical manufacturing industry is often accompanied by inorganic waste gas, organic waste gas, chemical comprehensive waste gas and other emissions. These waste gases are complex, difficult to collect and control, and may even be inhaled through breathing and skin, endan...
Due to the high requirement of inputs, nutrients, and water; maize is considered as the exhaustive crop. Previous research in Bangladesh (Barma et al., 2014) shown that cereals (rice, maize, wheat), jute, pulses and oilseeds can be cultivated very effectively through water saving ...
"2006 IPCC National Greenhouse Gas Inventory Guidelines" (Table1), this paper calculates the carbon emissions of 8 energy consumption (coal, coke, crude oil, gasoline, kerosene, diesel, natural gas and fuel oil) in 30 provinces in China from 2006 to 2016, the specific formula is as follows...
The above 8 types are raw coal, coke, crude oil, gasoline, kerosene, diesel, fuel oil and natural gas. Output Variables The added value (ADV) of the logistics industry is applied to measure the desirable output. In addition, taking 2004 as the base period, the added value of the ...
(139–145 g/day versus 116–117 g/day), although it was considered this may have reflected the higher vegetable oil content in UMB8 to limit intake for prevention of urea toxicity risk, with these blocks likely to have been less palatable [1]. This is an observation previously considered,...
Coal, crude oil, and natural gas are selected as energy sources for carbon emissions accounting because they account for about 94% of China’s total energy consumption [43]. We only consider direct emissions, excluding indirect emissions and process emissions in the measurement. 3.2.2. Control ...
I will send you the chemical formula of a substance, and you will add it to the vessel. If the vessel is empty, the substance will be added without any reaction. If there are residues from the previous reaction in the vessel, they will react with the new substance, leaving only the ...
