Shale gas a distant prospect?

In 2013 the US Energy Administration estimated that Europe contained 470 trillion cubic feet (Tcf) of potentially recoverable shale gas, equivalent to 80% of US reserves. Given the size of Europe’s potential shale gas reserves and the EU’s declared intent to constrain climate change, while still protecting energy security, it is surprising that exploration for shale gas has been so little and so slow. Poland, the UK, France, Ukraine, Romania and Germany are all countries, which are estimated to have significant shale gas resources, but, with only 55 rigs in operation, knowledge of Europe’s geological share heritage is sparse, though early indications are that the shale plays are deeper at around 5000-6000 metres compared to 3000-4000 metres in the US.

Both the UK and Poland are, by common consensus, thought to be the countries most likely to have commercial shale gas production by the mid-2020s. Both have many of the essential prerequisites including size of shale gas reserves, positive government and public support for exploration and the presence of US energy services companies. In England, independent exploration companies have pioneered exploration and between them have drilled 10 wells, of which one has been fracked. Environmental risk assessments, 2 and 3 D seismic surveys, flow testing of exploratory wells this year combined with new capital investment by large companies such as Total, Ineos and Centrica characterise activity to date. The recent round of onshore licences, government tax incentives and proposed legislation to the Trespass laws will, it is hoped, raise drilling activity to some 20-40 exploratory wells in the next two years. The UK, also has the “Benefit of extensive transmission and distribution grids to meet the requirements of new production” says Bob Palmer head of the Oil & Gas team for international law firm, CMS in London. See Figure 1.

With declining North Sea output, the current government is doing much to promote shale gas development. Whilst the most recent attitude survey found that over 50% of respondents favoured shale gas exploration reports the Shale Gas Investment Guide December 2014 considerable opposition to actual fracking from affected local communities and environmental interest groups remains. Moreover, with environmental impact studies and local government approvals for drilling and fracking to be won, progress has been slow as Howard Rogers, Oxford Institute for Energy Studies says, “I’m not holding my breath - due to the slow pace of approvals and a highly motivated anti-fracking lobby.”

Poland has Europe’s largest known reserves, strong public, and government support. However, “Up until now, the results of shale gas exploration in Europe have been disappointing”, states Gregory Zygan, Energy Specialist, Polish Ministry of the Environment. This is attributable, in part to the fact that comparatively little exploration activity has actually occurred - certainly not enough to determine the actual size of resource and its economic viability. As Howard Rogers, notes, “Since mid-2010, upstream companies in Poland have drilled some 66 wells with a further 20 completed by Spring 2015”. Disappointing results have led to the exit of Canada’s Talisman Energy, ExxonMobil, Marathon, Total and 3 Legs. Future development depends very much on the state energy company PGNiG and the government. Despite a pro-shale government, anxious to end its dependence on Russian gas, Poland has still not produced a new energy law and the rules and bureaucracy are often unclear and unstable. Given the urgency of energy security, the Polish government is introducing a new hydrocarbon law for 2015. To add to the difficulties, the gas pipeline infrastructure needed to link shale supplies with markets is inadequate and, given the traditional dependence on coal, only half of all households are currently connected to natural gas distribution network. See Figure 2.

In France, the moratorium of 2012 on fracking continues and public hostility to shale gas remains in place. However, a subsidiary of Total, the international oil company recently received three research permits for exploration in an area of southern France, thought to hold 84 Trillion TCF.

Elsewhere, exploration in Ukraine has been depressed by corruption and conflict causing RDS and ExxonMobil to suspend negotiations on planned investment. In Bulgaria the moratorium on shale drilling and public opposition continues. In Lithuania, shale exploration has become a national priority. However, strong public opposition to fracking remains forcing Chevron to suspend operations twice during 2013. Table 1 provides a bird’s eye view of shale gas developments and three prerequisites affecting the pace and location of development.

Inhibitors to shale gas development in Europe

The obstacles to shale gas development have been well and truly rehearsed. However, three aspects deserve comment. The first is the state of public opinion towards “fracking”. Public acceptance of hydraulic fracturing is an essential prerequisite yet, public attitudes are negative in much of the UK, Bulgaria, Spain, Germany and France. Shale exploration companies have failed to put their case to the media, the public, to local communities near proposed well sites and environmental interest groups. In essence, shale operators have failed to win a social licence to operate. As Richard Bass, Director of Energy, DNV states, “The main obstacle facing both industry and government in Europe is the misconception by the media of what fracking is about”. Meanwhile industry experts’ assertions that technological solutions can obviate concerns over water contamination, methane emissions and environmental damage are seemingly ignored.

There is no escape from the second obstacle namely high cost. Europe’s deeper shale plays and more complex geology adds to costs. Deep shale plays require heavier and stronger rigs and pumps, more fracking fluids, water and sand. To drill a 6,562-foot horizontal well in Poland costs around $11 million, if you are lucky, reported Bloomberg January 2014. As Rex W. Tillerson, CEO of Exxon Mobil explained, “Because the technology we have used so successfully in the States is simply not working on the Polish geology someone is going to have to spend a lot of money into basic R&D before it’s going to work”, reports Bloomberg November 2014. Another aspect of cost is the need for additional investment in an EU-wide pipeline network to create a unified gas market to transport the shale gas from production sites to consumers. As Howard Rogers points out, “If European shale gas can be developed at competitive prices; this has benefits in terms of balance of payments and also to a degree, security of supply.” However, shale gas must be price competitive against rival fuels such as natural gas, renewables, coal and LNG, if it is to find customers.

The third inhibitor to aggressive development of shale gas in Europe is the uncertainty of natural gas prices. As Bob Palmer asks, “The elephant in the room is the natural gas price: is it worth looking for more gas at this stage?” The potential impact of imports of American shale gas and its comparative price is impossible to assess before the average well-flow rate from a viable European shale play is established. Meanwhile, notes Grzegorz Zygan Polish Ministry of the Environment, “We have with the British government commissioned a joint study on the expected economic impact of shale gas production on their economies is to be published in spring 2015.”

Future:

The EU-level inconsistencies in reconciling climate change policies and security of supply policies have distracted attention away from the absence of a holistic EU-wide energy policy which envisages an integrated gas-pipeline network based upon a sound understanding of hydrocarbons’ future place as a major fuel source overcoming decades. If Europe is to continue to use hydrocarbons then, according to Richard Bass, the question should be - how is it extracted and where? And for now the real question is - will it pay to extract shale gas in Europe?
