Natural Gas with its Future

20 per cent share of natural gas in the world energy demand is fulfilled. Where does gas come from? How safe or the environment agree, and they will be provided katadinai or our strength?

Scientists believe that over millions of years to accumulate in layers and animals gachapata dhansabasesa, plankatana, dust and mud, etc. are covered under the study. Including underground heat, pressure, and gradually it is becoming as a result of bacterial decomposition of oil, coal and natural gas, one of whom is said to fossil fuels or fossil fuel. The accumulation of gas in the bottom of the situation at the situation at the level of flawless rock it turns out that a large volume of gas ksetreaneka gas field, a few decades paryantaprthibite trillion cubic meters, and the total volume of the biggest gas fields in the direction of the row is the first in Russia.

 
How is gas found?
Satellite (Remote Sensing satellite), Global pajisanim System (Global positioning system), sound (Reflection seismology) and computer (Computer). Ultrasound is used in the medical science Seismology reflex test mataucu sound levels that are reflected back to the world stage. The sound waves to examine the structure of the channel is to know about computers. Bhaibretarera usually minor blast or the sound produced is sent inside bhustarera and three-dimensional images of the computer that it is an idea of ​​the potential gas fields. High pressure gas exploration in the sea air, or water vapor is sent to the bottom of the sea. Haidrophona reflects the pressure vessel through the device reached the study examines the potential gas field where the idea of ​​computers grows.

 
To be economically profitable gas and gas pressure must have sufficient amount of gas. Easy to measure gas pressure, but the total amount of gas to be determined relatively kathinaparimana assess a given method of measuring the amount of gas pressure gas pressure measured out again. If the pressure difference can be seen in a small amount of gas is higher than the pressure variations in the amount of reserves will be less.

Processing of Gas
After the extraction of the gas pipe were taken to the refinery or refinery for refining. The unexpected refinery mixed gas used in the gas such as carbon dioxide, hydrogen sulfide, sulfur dioxide, water vapor, etc., are separated. The distillation process to separate nitrogen gas from the gas hayaananya byabaharya valued, such as helium, propane butane, Ethel is different. So what is left of the natural gas. So we have all of the methane gas are used as fuel gas is methane. Independent methane, letters and odorless gas, and with a little amount of sulfur compound to secure dahyamithenake misye substance that is given. The pungent smell of sulfur gas emissions, primarily due to the blast occurred is unable to detect and avoid other fossil fuels such as coal or oil yayagyasa safe, clean and environmentally friendly.

 
The temperature is reduced to facilitate the transport of gas taralibhuta. Butane and propane taralibhuta petroleum gas or LP, G (liquefied Petrolium Gas) cylinders used for cooking or transport of propane hayabiutena and plastics, synthetic fibers, various types of solvents, and other materials are made.

How long will gas?
Ideas can be found in the future will have an additional 45 per cent of the current rate of gas to be used if you have more than 60 years, the use of gas is growing rapidly yabejbalanira puts our energy, run out of fossil fuels, nuclear and renewable or nuclear energy energy sources, such as suryarasmi, or wind energy to meet future energy needs can do? Time will tell.

Exploration History of Natural Gas of Bangladesh

The exploration action of petroleum products is over 100 years old in Bangladesh. The first exploration activity started with some topographic maps of Chittagong Hill Tracts and some simplified surveys were done. The first exploration started from 1914 to 1933 by Burma Oil Company (BOC). The second of phase petroleum exploration began after partition of Indian subcontinent. Three international oil companies and the state owned oil company (OGDC) were active in different part of the country. During phase II, Shell Oil discovered the most successful drilling operation; Rashidpur, Kailashtila,  Titas,  Habigonj  and  Bakhrabad  gas fields were discovered. 

After the independence of Bangladesh in 1971, the petroleum exploration gathered pace. In this period, the first offshore gas field, Kutubdia was discovered. The country was first divided into 23 major blocks including offshore area. During 1995-2000, the  foreign companies Fig.2 drilled 10 exploratory wells and discovered 1 offshore gas field (Sangu in 1996 by Cairns Energy) and two onshore gas fields (Bibyana in 1997 and Moulovibazar in 1998). After some more successful drilling by Tullow Oil, Bangura gas field was discovered in 2004.

BAPEX, (Petrobangla exploratory subsidiary) drilled two wells and discovered two gas fields, i.e. Shahbazpur in 1995 and Saldanadi in 1996. BAPEX drilled one well in late 2004 and announced discovery of Srikail gas field in Comilla in January 2005. It is very interesting data that the national oil companies of Bangladesh have a discovery success rate over 80% Fig.3 compared to the multinational oil companies. Digital multi fold seismic data acquisition started in 1977, when Prakla was engaged under the German technical Assistance Program. In 1978 Petrobangla started acquiring multi fold analog seismic data, Fig.4 but in 1979 it moved into the digital domain. During 1986-87 Shell recorded over 1,500 km of multi fold data and these are available in BAPEX Data Center.
