All well for Deep Casing Tools in Malaysia
Deep Casing Tools (DCT), together with its Asia Pacific regional partner EFTECH, has successfully ran three more of its Turborunner TM tools with Shell Sarawak, despite challenging conditions heightened by COVID-19.
The scope of work, which was awarded to DCT in 2018, required horizontal well completions in six new wells to ensure target depth (TD) could be reached. The work was carried out on the Naga 7 jack-up rig located offshore, Miri, Sarawak, which Shell Sarawak contracted from Velesto Drilling in 2018 to support its offshore oil exploration and production, and offshore gas production in the region.
Despite challenging conditions including tight spots in all six wells, the runs were completed successfully by August 2020 by deploying DCT’s best in class turbine-powered completions tool, Turborunner TM, which allowed the energy major to reach TD.
Turborunner TM was deployed due to its track record of landing completion strings and liners at TD first time, even in complex wells and with challenging open hole conditions. It uses high speed reaming to reduce potential equipment damage, create less downtime, eliminate wiper trips and open hole exposure and enable cost-effective drill through and drill ahead.
In addition to the tight spots, the restrictions on travel for overseas personnel as a result of COVID-19 created further challenges. DCT was able to overcome this as a result of its well-established relationship with EFTECH, the leading provider of process and pipeline services to the offshore industry, which is headquartered in Malaysia.
Together, DCT and EFTECH were able to provide on-the-ground field support to oversee the running of the tools, whilst complying with social distancing requirements set by the local government and the operator. This was bolstered by remote support and monitoring by DCT’s technical operations team based at its headquarters in Aberdeen. Furthermore, the customer benefited from rapid tool mobilisation due to the partnership’s in-region warehouses facilities.
Neil Hathaway, Regional Manager at DCT, said: “The success of this project is testament to our commitment over the last decade to grow our international capabilities through a network of experienced and dedicated partners around the world. By partnering with EFTECH who have amassed nearly two decades of experience of servicing the offshore sector in the Asia Pacific region, we were able to deliver an unrivalled level of service to our customer Shell Sarawak.
“It is also another excellent example of our simple innovation which make operations safer and more efficient, even in the most complex and challenging conditions. We are looking forward to building the relationship further with EFTECH and Shell Sarawak, as well as continuing to bring further innovative solutions to the oil and gas downhole market.”
Form Energy receives funding power for iron-air batteries
Form Energy believes it has cracked the conundrum of commercialising grid storage through iron-air batteries - and some of the biggest names in industry are backing its potential.
The startup recently announced the battery chemistry of its first commercial product and a $200 million Series D financing round led by ArcelorMittal’s XCarb innovation fund. Founded in 2017, Form Energy is backed by investors Eni Next LLC, MIT’s The Engine, Breakthrough Energy Ventures, Prelude Ventures, Capricorn Investment Group and Macquarie Capital.
While solar and wind resources are the lowest marginal cost sources of electricity, the grid faces a challenge: how to manage the multi-day variability of renewable energy, even in periods of multi-day weather events, without sacrificing energy reliability or affordability.
Moreover, while Lithium-ion batteries are well suited to fast bursts of energy production, they run out of energy after just a few hours. Iron-air batteries, however, are predicted to have theoretical energy densities of more than 1,200 Wh/kg according to Renaissance of the iron-air battery (phys.org)
The active components of Form Energy's iron-air battery system are some of the cheapest, and most abundant materials: iron, water, and air. Iron-air batteries are the best solution to balance the multi-day variability of renewable energy due to their extremely low cost, safety, durability, and global scalability.
It claims its first commercial product is a rechargeable iron-air battery capable of delivering electricity for 100 hours at system costs competitive with conventional power plants and at less than 1/10th the cost of lithium-ion and can be optimised to store electricity for 100 hours at system costs competitive with legacy power plants.
"This product is our first step to tackling the biggest barrier to deep decarbonisation: making renewable energy available when and where it’s needed, even during multiple days of extreme weather, grid outages, or periods of low renewable generation," it states.
Mateo Jaramillo, CEO and Co-founder of Form Energy, said it conducted a broad review of available technologies and has reinvented the iron-air battery to optimise it for multi-day energy storage for the electric grid. "With this technology, we are tackling the biggest barrier to deep decarbonization: making renewable energy available when and where it’s needed, even during multiple days of extreme weather or grid outages," he said.
Form Energy and ArcelorMittal are working jointly on the development of iron materials which ArcelorMittal would non-exclusively supply for Form’s battery systems. Form Energy intends to source the iron domestically and manufacture the battery systems near where they will be sited. Form Energy’s first project is with Minnesota-based utility Great River Energy, located near the heart of the American Iron Range.
Greg Ludkovsky, Global Head of Research and Development at ArcelorMittal, believes Form Energy is at the leading edge of developments in the long-duration, grid-scale battery storage space. "The multi-day energy storage technology they have developed holds exciting potential to overcome the issue of intermittent supply of renewable energy."
Investors in Form Energy's November 2020 round included Energy Impact Partners, NGP Energy Technology Partners III, and Temasek.
In May 2020, it signed a contract with Minnesota-based utility Great River Energy to jointly deploy a 1MW / 150MWh pilot project to be located in Cambridge, MN. Great River Energy is Minnesota's second-largest electric utility and the fifth largest generation and transmission cooperative in the US.
Last week Helena and Energy Vault announced a strategic partnership to identify additional opportunities for Energy Vault’s waste remediation technologies as the company begins deployment of its energy storage system worldwide. It received new investment from Saudi Aramco Energy Ventures (SAEV) in June.
Maoneng has revealed more details of its proposed 240MWp / 480MWh Battery Energy Storage System (BESS) on Victoria’s Mornington Peninsula in Australia (click here).
The BESS represents hundreds of millions of dollars of investment that will improve electricity grid reliability and network stability by drawing energy from the grid during off-peak periods for battery storage, and dispatching energy to the grid during peak periods.
