Drummond ordered to halt CBM gas production
Colombia's high administrative court ordered coal miner Drummond to halt coal bed methane (CBM) gas production.
The temporary ruling tasks the mines and energy ministry and hydrocarbons regulator ANH to enforce the suspension of CBM production at the Caporo field, located in the Caribbean province of Cesar, by no later than 13 March 2020.
Drummond's CBM project has drawn the scrutiny of environmental groups in the wake of a court-ordered ban on unconventional drilling that was not initially associated with CBM, but rather to hydraulic fracturing.
Even though CBM is listed as an unconventional deposit, the technique used at Caporo is conventional, the government's environmental regulator ANLA has said.
But in its new decision, the State Council determined that CBM drilling falls under the unconventional umbrella that is currently prohibited in Colombia, except for recently authorized pilot projects.
"Hydraulic stimulation in conventional reservoirs, in horizontal or vertical wells, is the means to achieve extraction, activities that are currently suspended ....it would be a contradiction to allow production of unconventional deposits to continue because it is clear and indisputable that this activity is temporarily prohibited," the State Council said in its 30-page ruling.
Drummond, which is Colombia's top coal producer, has said it uses conventional vertical drilling at Caporo, similar to the method that has been used in the country for more than 50 years in large oil fields such as Cusiana, Cupiagua and Apiay, rather than horizontal drilling that would be used for hydraulic fracturing. The company declined to respond to queries sent today.
Drummond started CBM production at its La Loma license in the second half of 2018. The firm has drilled 15 vertical wells at Caporo between 2017 and the first half of 2018, and those wells will be halted with the court's order.
The State Council's decision is a blow to the oil industry, which has a green light to set up pilot unconventional drilling projects in Colombia.
Environmental groups including Corporación Podion and the Colombia Free of Fracking Alliance had petitioned the State Council to halt the CBM project because they said it violates the temporary ban on unconventional drilling.
In a 6,462-hectare area known as Caporo North, Drummond plans to drill 57 gas production wells, but to increase output to 14mn cf/d Drummond will need new environmental licenses, the company has said.
The firm signed the exploration and production contract to develop the field in 2004, while in February 2012, Drummond declared the commercial viability of CBM on its La Loma license. Drummond says it has invested $43mn to explore for CBM at La Loma.
The company discovered CBM in the Caporo 1, Iguana 1 and Hicotea 1 wells in 2007-10, according to the ANH.
Drummond's had planned to produce shale gas using fracturing techniques at another section of La Loma, but the initiative is halted until the State Council issues a definitive ruling, which is expected to come in 2020.
Speaking at a mining event today, mines and energy minister Maria Fernanda Suarez said that the government will review the new ruling.
The State Council also ordered the country's controller's office and attorney general's office to oversee the process of suspending CBM activities.

NSTA fines Neo Energy for North Sea methane venting
NSTA fines Neo Energy for North Sea methane venting
London, 18 April (Argus) — UK offshore regulator the North Sea Transition Authority (NSTA) has fined UK upstream firm Neo Energy £100,000 for breaching its methane venting permit at North Sea fields. The company emitted 1,200t of methane in excess of its permit from the Donan, Lochranza and Balloch fields in the first nine months of 2022. Neo had permission to vent 378t of methane from installations at these fields in that year, but incorrectly assigned volumes vented through unlit flares to its flaring consent, the NSTA found. Neo showed a "lack of oversight" by failing to detect the licence breach for seven months, NSTA said. The company reached its annual limit by 21 March 2022, but continued venting without authorisation until October 2022. The company said it did not update its flare and vent allocation process to reflect NSTA guidance updated in 2021, and as such was still assigning its flaring and venting according to previous guidance. Neo becomes the fourth company to be fined by the NSTA over breaches relating to flaring and venting consents. The regulator in 2022 sanctioned Equinor and EnQuest and last year fined Spanish utility Repsol for consent breaches. The four companies have been fined a total of £475,000 for the breaches. And the regulator in February had four more investigations under way for breaches of vent consents. Neo Energy's fine is equivalent to £2.98/t of CO2e emitted, assuming a global warming potential of methane that is 28 times that of CO2 on a 100-year time scale, compared with a UK emissions trading system price of £34.40/t of CO2e on 17 April. The UK offshore industry targets a 50pc reduction in production emissions of greenhouse gases by 2030, from a 2018 baseline. And it intends to end all routine venting and flaring by that year. The regulator last year warned that "further, sustained action" would be needed to reach the 2030 emissions reduction goal. Methane emissions from offshore gas fell in recent years, to 1mn t in 2022 from 1.6mn t in 2018, according to NSTA data. Roughly half of methane emissions in the sector in recent years has been produced by venting, while flaring makes up about a quarter of the emissions. The UK government is a member of the Global Methane Pledge group of countries that aims to reduce methane emissions by 30pc by 2030 from a 2020 baseline.

Australia’s Queensland legislates emissions targets
Australia’s Queensland legislates emissions targets
Sydney, 18 April (Argus) — Australia's Queensland state today approved two separate laws setting renewable energy and emissions reduction targets over the next decade, as it transitions away from a coal-fired dependent power generation system. Queensland set net greenhouse gas (GHG) emissions reduction targets of 30pc below 2005 levels by 2030, 75pc by 2035 and zero by 2050 under the Clean Economy Jobs Act, while theEnergy (Renewable Transformation and Jobs) Act sets renewable energy targets of 50pc by 2030, 70pc by 2032 and 80pc by 2035. The state is on track to surpass the 2030 emissions target, latest data show, as it achieved a 29pc reduction in 2021. Even though the share of renewables in the power mix last year was the lowest across Australia at 26.9pc, it has been increasing consistently since 2015 when it was 4.5pc, according to data from the National Electricity Market's OpenNem website. Coal-fired generation has been steadily falling, down to 42.9TWh or a 65.7pc share in 2023 from 52.9TWh or 83pc in 2018. Most of Queensland's coal-fired plants belong to state-owned utilities, which the previous Labor party-led government of Annastacia Palaszczuk indicated would stop burning coal by 2035 . The new Labor party premier Steven Miles disclosed the 75pc emissions reduction target by 2035 in his first speech as leader last December. The Energy Act locks in public ownership of electricity assets, ensuring that at least 54pc of power generation assets above 30MW remain under state control, as well as 100pc of all transmission and distribution assets and 100pc of so-called "deep storage" assets — pumped hydro plants with at least 1.5GW of capacity. The government will need to prepare and publish a public ownership strategy for the July 2025-June 2030 and July 2030-June 2035 periods. A fund totalling A$150mn ($97mn) will also be set up to ensure workers at existing state-owned coal-fired power plants and associated coal mines have access to new jobs and training or financial assistance during the transition. The Clean Economy Jobs Act sees the government receiving advice from an expert panel on the measures needed to reduce emissions. The government will need to develop and publish sector plans by the end of 2025 with annual progress reports to Queensland's parliament.

BHP to expand gas-fired West Australia power station
BHP to expand gas-fired West Australia power station
Sydney, 17 April (Argus) — Australian resources firm BHP plans to increase power generation at its 154MW Yarnima gas and diesel-fired facility near the Pilbara iron ore mining hub of Newman in Western Australia (WA) state. The proposal, according to documents filed with WA's Environmental Protection Authority (EPA), will see output increase by 85MW to a total of 239MW through gas reciprocating engines and associated infrastructure with up to 120MW of nominal new capacity to be built in stages. Peak scope 1 greenhouse gas (GHG) emissions from the project are predicted to be 480,030 t/yr of carbon dioxide equivalent (CO2e), while scope 3 emissions related to supplying the gas are expected to be 37,260t CO2e/yr. Power demand at BHP's iron ore operations in the Pilbara is forecast to increase from 150MW currently to 1GW by 2040, as the company reduces its GHG emissions through electrification of its rail and mining fleets and must balance renewables with firmed generation. The iron ore mining sector is a large-scale producer of Australian GHG emissions through its Pilbara-based operations. Displacing liquid fuels such as diesel, which Australia consumes at an average rate of around 500,000 b/d by electrifying processes and switching to lower CO2-emitting sources such as gas, is expected to trend as Australia's largest polluters meet government mandates . Yarmina currently runs a 35MW diesel-fired temporary power station as part of its installed capacity. Canadian energy firm TransAlta earlier this year lodged plans to build a new 150MW gas-fired power station for BHP's Nickel West operations in WA's Northern Goldfields region. WA's domestic market is likely to be short on gas later this decade despite being Australia's largest LNG export state, the Australian Energy Market Operator (Aemo) has warned in its Western Australia Gas Statement of Opportunities. Aemo's modelling released last year shows the closure of WA's state-owned coal-fired power stations will drive increased requirements for gas-fired electricity generation in the next decade.

Shale discipline even at $200/bl: Ex-Pioneer CEO
Shale discipline even at $200/bl: Ex-Pioneer CEO
New York, 16 April (Argus) — Public independent shale oil producers will remain disciplined and keep production steady even if crude prices soar on geopolitical tensions, according to the former chief executive officer of Pioneer Natural Resources. "Even if oil gets to $200/bl, the independent producers are going to be disciplined," Scott Sheffield said today at the Columbia Global Energy Summit in New York. Public independents showed restraint when oil prices jumped in the immediate aftermath of Russia's invasion of Ukraine in 2022, as they focused on improving shareholder returns rather than ramping up production to take advantage of short-term prices, he said. One benefit of the recent wave of consolidation is that it may kickstart some growth in a sector that has showered shareholders with excess cash via dividends and share buybacks in recent years. Before Pioneer agreed to be bought for $59.5bn by ExxonMobil late last year, the company was only increasing output at around 5pc a year. Once the acquisition closes, the top US oil major is going to grow Pioneer's assets at 10-15pc a year, said Sheffield. "That's an example where somebody is stepping up and adding production," he added. Global crude prices have moved very little since the weekend when Israel and allies thwarted a massive missile and drone attack from Iran. WTI today fell by just 5¢/bl to $85.36/bl while June Ice Brent fell by 8¢/bl to $90.02/bl. The industry veteran stepped down as chief executive at the end of last year but remains on the board of Pioneer.
