BP and Reliance are set to expand partnership to develop deep-water gas fields
June 15, 2017

BP and RIL are set to develop already-discovered deep-water gas fields – ‘R-Series’ deep water gas fields in Block KGD6 off the east coast of India, bringing new gas production for India. The R-Series (D34) project is a dry gas development in water-depths of more than 2,000 metres, approximately 70 kilometres offshore. These R-series fields will be developed as subsea tieback to the existing control and riser platform off Block KGD6 and this project is expected to produce up to 12 million cubic metres (425 million cubic feet) of gas a day, estimated to come on stream in 2020.

IndianOil signs a Statement of Intent to Construct World’s First Refinery Off Gas-to-Bioethanol Production Facility in India
July 10, 2017

Indian Oil Corporation Limited (IndianOil) and, LanzaTech, a carbon recycling company, have signed a Statement of Intent to construct the world’s first refinery off gas-to-bioethanol production facility in India.

LanzaTech has developed a gas fermentation process to make fuels and chemicals wherein instead of sugars and yeast, the company uses a biological catalyst to ferment waste gas emissions. This will allow India to produce 40-50 KMTA of ethanol per refinery while saving about 1 million tonnes of CO2 per annum which is the equivalent emissions savings as taking 850,000 cars off the road in India each year. The potential impact of using off-gases from the refining sector in India is amassed to be considerable and a landmark feat in India’s attempt to reduce CO2 emissions.

Statoil and its partners start production on the Byrding field
July 28, 2017

In 2016, when Statoil acquired Wintershall Norge’s 25% share in Bryding field, it increased its share from 45% to 70%. Statoil and its partners have started production and recoverable volumes are estimated to be equivalent to a good 11 million barrels of oil.

Coalbed Methane, or CBM commonly referred to as an “unconventional” form of natural gas, is present in coal. The properties of CBM such as its storage through the adsorption to the coal itself rather than in the pore space of the rock, unlike most “conventional” gases, is what categorizes it as an unconventional form of gas. CBM, as the name suggests, largely constitutes of methane with ethane and CO2 has a share of 2% or lower. It has also been classified as a “sweet gas” due to the absence of hydrogen sulfide in it.

In the past, since the commercial extraction of methane was not possible, CBM was expelled into the surroundings intentionally, to reduce the chances of deaths and explosions. The gas was known to escape into adjacent water bodies (primarily ground water reserves), or percolate to the surface, proving a hazard for the neighbourhood and thus, often led to evacuation of nearby dwellings.

Research, over a period of time, has evidenced the usefulness of CBM and efforts for the commercial extraction of the same are being made. CBM has evolved to be a substitute to the depleting natural resources and as a contributor to the fulfilment of the growing demands of the people.

Formation of CBM

CBM is formed during the process of coalification, the transformation of plant material into coal. Thermogenic methane is generally formed in the temperatures of 157-221 degrees. It is generally noted, deeper the coal, higher the content of methane. Due to large internal surface area, coal is able to store an enormous amount of gas. Due to its microporous structure, coal stores around 6-7 times of gas more than equivalent volume of rock in a conventional reservoir.

Extraction of CBM

CBM is held in place by water pressure and to extract CBM, it is necessary for the water to be pumped out, prior to the commencement of extraction of CBM. The gas follows the path of water, ultimately getting pumped out too. The gas is captured at the surface and then transferred through pipelines. Since the gas is stored within and between the coals, coals are first broken up using fracking fluid, which makes it easier for the gas to escape.

There are generally 2 methods for extraction of CBM:

  1. Pre – mining drainage methods
  2. Post – mining drainage methods

 Pre-mining drainage method

This method has been proven to be generally ineffective in low permeability seams. The method includes drilling of bore wells into the virgin coal seam. For increasing the permeability, techniques like hydro fracture, blasting and chemical reactions are used. Pumps are then installed for the removal of water from cracks and cleats allow the gas to be passed. Some pumps create vacuum for better methane recovery. The water pressure does not allow the methane to escape, thus these vacuum pumps evacuate the water, then suck methane out. But these pumps are generally not used due to water level in nearby strata being lowered.

Post-mining drainage method

This method was developed in Germany over 40 years ago but seen various changes with time. The underground cross measure which falls under the ambit of the post mining drainage method includes boreholes drilled at an angle above or below the coal, connected to a methane removal system. Gas drainage boreholes in the roof or floor are also amongst the other techniques. Here, a steel pipe is used to line the first section of the borehole with a diameter suitable enough to offer least resistance to methane gushing out. Long horizontal boreholes above or below worked seam technique proved to be successful in Australia. The boreholes are laid at a competent horizon for a projected long panel.

Environmental issues

Methane lands second only after carbon dioxide for the gases contending greenhouse gas. During drilling, certain quantity of gas escapes into atmosphere. Though the escaped gas stays in the atmosphere for a short period, the warming potential is 21 times more than CO2.

The process of extraction of CBM involves certain hydraulic fracturing and extraction of water for around the CBM reserves. While hydraulic fracturing includes injecting mixture of heavy chemicals which in turn enter the ground water, it also requires the water to be pumped out which leads to depletion in the ground water level.

CBM in India

India has the fifth largest reserve of coal in the world and these coal reserves are deduced to bear a suitable environment for development of CBM reserves. Indian CBM reserves are estimated at around 2.60 trillion m3.

 CBM’s potential to be utilised as an alternate resource for the depleting natural resources has led to the formation of multiple policies and guidelines for facilitating the process of methane extraction. The consequent boost in this sector will mean higher economy growth as well as higher use of alternate resource.

CBM Law and Policy

In addition to the Oilfields (Regulation and Development) Act, 1948; The Petroleum and Natural Gas Rules, 1959; New Exploration Licensing Policy (NELP); and Hydrocarbon Exploration Licensing Policy (HELP), the Government has formulated various policies for the governance of extraction and to harness the potential of CBM.

CBM Policy, 1997

This policy was primarily introduced in order to offer the blocks of CBM for the purpose of exploration and exploitation through the open completive bidding system.

Policy for Early Monetization of CBM, 2017

Applicable from April 2017, the Government, so as to develop alternate sources of natural gas including CBM and to promote a gas based economy, has attempted to streamline operational issues and expedite marketing and pricing freedom for CBM.

The underlying principle is that Indian producers should get a similar price as the gas producers elsewhere are getting. Under this policy, CBM is to be sold at Arm’s Length Price in the market. A fully transparent and competitive process is to be ensured while deciding the price in Arm’s Length Sales so that all the parties to the contract realize the best value of the product. In an event where the buyer cannot be identified, CBM can be sold to an affiliate by the contractor. Royalty and other dues to the Government will be payable on the basis of Petroleum Planning & Analysis Cell (PPAC) notified prices or selling prices, whichever is higher.
