In September 2011 Cuadrilla announced its Gas-in-Place findings. We estimate that there is 200 trillion cubic feet (tcf) of natural Gas in Place in the Bowland shale.
This estimate was a result of considerable scientific analysis of findings from our exploration work, which included taking samples from the shale rock during drilling and from flow-back analysis after hydraulic fracturing. Our geologists and technicians are experts in their field and have arrived at this estimation following careful analysis of the available data.

http://en.wikipedia.org/wiki/Marcellus_ ... atural_Gas (good site coverage... btw)Reserve estimates
The United States Geological Survey had estimated that the Marcellus contained only 54 km3 (1.9×1012 cu ft) (where x1012 = trillion, and is referred to as 1.9 TCF) of technically recoverable natural gas in a 2002 publication. In April 2009, the United States Department of Energy estimated the Marcellus to contain 262 TCF of recoverable gas.
State University of New York at Fredonia geology professor Gary Lash has calculated that more than 14,000 km3 (4.9×1014 cu ft) (490 TCF) of natural gas may be contained in the Marcellus black shale beds that lie between New York state and West Virginia. At the present level of technology, he believes approximately 10% of this – 1,400 km3 (4.9×1013 cu ft) (49 TCF) – could be recovered. This is enough to satisfy approximately two years' of total U.S. consumption, or a total value of two hundred billion dollars at winter 2010 – spring 2011 wellhead prices. That figure is part of an increase of as much as approximately one trillion United States dollars in the value of all recoverable reserves in the US attributable to improved recovery through vertical drilling and fracking.
In 2008, Terry Engelder, a Pennsylvania State University geosciences professor called his estimate of 4.8 trillion cubic metres (170 trillion cubic feet) conservative. In November 2008, based on drilling results, Engelder increased his estimate of the amount of natural gas in the Marcellus to 363 trillion cubic feet (10.3 trillion cubic metres) of recoverable resource, which would be enough to supply U.S. consumption for at least fourteen years. That estimate assumed some acreage in the Marcellus would not be gas bearing. If the entire formation did contain gas, Engelder said the formation could contain 4,359 TCF. Assuming a 30% recovery rate, this would lead to a 1,307 TCF.
According to the Financial Post, the boom in US shale oil production, using horizontal drilling and hydraulic fracturing, created thousands of jobs and reduced United States dependence on imported gas. In 2008 there was a natural gas drilling boom  in the Fort Worth Basin of the Barnett Shale formation in north Texas, which is similar to the Marcellus shale formation, produced strong drilling results.
During the 2012 presidential campaign, GOP Primary Candidate Rick Perry cited a study funded by the Marcellus Shale Coalition that fracking the Marcellus Formation is expected to create a quarter million jobs under the current policies of the Obama administration.
To extract the shale gas at more commercially viable rates, directional drilling is done to depths of 7,000 to 10,000 ft (2,100 to 3,000 m) underground to reach the formation, and then water and a mixture of chemicals is pumped into the rock under high pressure in a process known as hydraulic fracturing to release the gas from the low permeability shale. Although hydraulic fracturing has been used since the middle of the 20th century, its use in horizontal wells in laterally extensive shale formations was perfected around the turn of the 21st century outside Fort Worth, Texas to tap the reserves in the Barnett Formation shales of the Bend Arch-Fort Worth Basin, that are now the most prolific source of unconventional gas in the continental United States. The Marcellus covers several times more area, stretching 600 miles (970 km), compared to a linear extent of only 170 miles (270 km) for the Barnett.

iGas Vastly Increases UK Shale Gas Estimates to 170 Trillion Cubic Feet
By James Burgess | Mon, 03 June 2013 21:44
The energy company iGas, has increased its estimates of shale gas in the UK after a recent study suggests that there may be between 15 and 170 trillion cubic feet of shale gas buried in a 300 square mile are of Cheshire.
The most likely volume is around 102 trillion, still far more than the 9 trillion cubic feet initially predicted, and enough to supply the UK with years of energy, and reduce its imports. The UK currently uses around 3 trillion cubic feet of natural gas a year.
After restrictions on hydraulic fracturing activities were lifted last December, some energy firms have been eagerly exploring the shale potential in the UK. Andrew Austin, the Chief Executive Officer of iGas, said that his companies “licenses have a very significant shale gas resource with the potential to transform the company and materially benefit the communities in which we operate.”

In 2011, Cuadrilla, a rival shale gas firm operating in the UK, estimated that it owned roughly 200 trillion cubic feet of shale gas, with the CEO Mark Miller claiming that around 10-30% of those resources would actually be extracted.
Green groups remain suspicious of the early estimates being released by shale companies around the UK, and warn that no one should get excited about the country’s shale potential just yet. Doug Parr, a chief scientist and policy director from Greenpeace, warned that “deciding how much gas there is based on the word of a shale gas firm is like buying a second-hand car without lifting up the bonnet and asking the price. iGas may be keen to impress its investors in China but these figures are just hype. The world's largest oil and gas firms were attracted to Poland by similar claims - now they are rushing to leave.”
iGas has announced that it will begin exploratory drilling later in the year in an attempt to gather more accurate data on the volume of shale gas available to them.

By Georgios Georgiou - 2013-03-15T16:37:22Z
Cyprus’s natural gas reserves in its territorial waters could be as much as 60 trillion cubic feet, the head of the country’s state hydrocarbons company said.
The country has already granted licenses for exploratory drilling in six blocks that could contain as much as 40 trillion cubic feet of natural gas, according to Charalambos Ellinas, chairman of Kretyk, as the company is known, in Nicosia today.
Noble Energy Inc. (NBL) will begin exploratory drilling in block 12 of the Economic Exclusion Zone, which has reserves of as much as 8 trillion cubic feet, in the third quarter, Commerce and Industry Minister George Lakkotrypis said on March 13.
Cyprus has so far given gas exploration licenses to Noble, Total SA (FP) and a venture of Eni SpA (ENI) and Korea Gas Corp. (036460)

http://en.wikipedia.org/wiki/Natural_gas_in_BangladeshIn recent years, several trillion cubic feet (TCF) of natural gas have been added to the confirmed 10.5 TCF known as of 1996. Due to the fact that there has been comparatively little exploration to date, estimates of the total extractable natural gas resource in Bangladesh are uncertain and vary widely. An estimate of 20 TCF is gaining acceptance among experts, but some argue that experiences in comparable basins elsewhere in the world suggest that the ultimate recoverable resource could be as high as 50 TCF or even 100 TCF.
At the current rate of natural gas use in Bangladesh (1000 mmcfd), the current estimated proven reserves would last 45 years. Even if the present rate of use increases at 10 per cent per year, these reserves would last about 17 years. A reserve-production Reserves-to-production ratio of 17 is higher than that for most industrial countries heavily dependent on natural gas, examples being Norway, Canada, U.S., and U.K. Here only the R/P ratio of gas is being considered for comparison. Relative to Bangladesh, these industrial countries have more diverse indigenous energy sources such as coal, oil and nuclear. The U.S. still uses coal to produce more than half its electricity.
There are huge resources of gas in Bangladesh. Places where gas is commercially refines include: Titas, Habiganj, Bakhrabad, Narshingdi, Meghna, Sylhet, Kailashtilla, Rashidpur, Beanibazar, Fenchuganj and Salda Nadi.
In 2001, Petrobangla Director Major Raihanul Abedin initiated the national plan to decrease the use of using liquid fuels, by introducing natural gas conversion. He thought if cars could be converted to use cooking gas instead of rather harmful fuels, the carbon emission would decrease exponentially. He was given the permission by the Prime Minister Khaleda Zia to carry out his plans. As a result, Asian Development Bank funded his scheme and today more than 80% of Bangladeshi vehicles are run on gas which has lessened pollution significantly.

April 10 (Bloomberg) — Tanzania sees natural-gas reserves more than doubling by early 2015 from the 40 trillion cubic feet discovered by companies including Statoil ASA, as the country prepares to offer new exploration blocks as early as September.
“We have enormous amounts of gas,” Energy and Minerals Minister Sospeter Muhongo said in an interview yesterday in Oslo. “We are now at 40 tcf and I’m sure in the next two years we should be at more than a 100 tcf.”
Statoil, Norway’s biggest energy company, last month raised estimates for discoveries in Tanzania’s Block 2 to as much as 13 trillion cubic feet of recoverable resources, enough to build a liquefied natural gas plant with Britain’s BG Group Plc. The U.K. company has found 10 trillion cubic feet in neighboring blocks. Statoil said drilling on two to three new prospects may yield “high-impact” finds in 2013, defined as discoveries with reserves of more than 250 million barrels of oil equivalent.
More than 100 trillion cubic feet have been found in the area including neighbouring Mozambique, where Eni SpA made the biggest gas discovery of the decade. Mozambique may have 250 trillion cubic feet of reserves, according to the country’s state-backed company Empresa Nacional de Hidrocarbonetos.
Tanzania will offer exploration permits between September and November, Muhongo said, after the country delayed a planned licensing round for nine blocks in September last year. Tanzania Petroleum Development Corp. will decide on a date for the round, he said, without giving the number of blocks to be awarded.
