Researchers from The University of Western Australia are aiming to prevent calcium scale in oil and gas pipelines through the innovative use of an environmentally friendly seaweed extract.
Dr Brendan Graham, Dr Zachary Aman and Professor Eric May from UWA’s Fluid Science and Resources research group are investigating using alginate, a naturally occurring product and common food additive, to target scale formation in pipelines which can result in major production losses for industry.
“Scale formation in oil and gas pipelines has always been a liability for the oil and gas industry as it reduces production rates. In some cases scale formation can result in a loss of production of over $1,000,000 per day from a single affected well,” Dr Graham said.
“Traditionally, dissolving calcium from gas producing pipelines involves pumping chemicals into pipes to remove the scale and then another batch of chemicals to prevent further scale formation.
“The innovative use of a natural product from the ocean would markedly reduce any harmful impact on the environment. Its use would represent a natural cycle of resources: the product comes from the ocean and could enable oil and gas companies to employ environmentally friendly production techniques.”
Using their diverse knowledge of chemistry and chemical engineering, the researchers tested alginate in various field scenarios and found not all types of seaweed alginate effectively prevent calcium from forming on the pipe walls.
They discovered the most effective type of alginate comes from brown seaweed and lends itself to an impressive return on investment as it is recyclable, renewable and potentially a far superior solution to the current methods of preventing scale formation in pipelines.
“Alginates are currently used in a number of industries such as the medical and food industries, to control the release of calcium from watery solutions through the formation of water insoluble gels,” Dr Aman said.
“So far there’s been no information available to describe the effectiveness of alginates in the oil and gas industry. By using alginate in pipelines, we can control and prevent scale formation without disrupting the protective iron carbonate layer in flowlines,” he said.
The next stage of the technology development includes a detailed qualification plan for the development of this new approach to scale prevention, allowing for continued investigation of the applications of alginate across the industry, and eventually for deployment in the field.
“It’s extremely exciting to work on industry-funded research that so far has gone precisely to plan and aligns exactly with our expertise,” Professor May said.

In the last week, global crude oil price benchmarks have leapt up by some US$5/b. Brent is now in the US$66/b range, while WTI maintains its preferred US$10/b discount at US$56/b. On the surface, it would seem that the new OPEC+ supply deal – scheduled to last until April – is working. But the drivers pushing on the current rally are a bit more complicated.
Pledges by OPEC members are the main force behind the rise. After displaying some reticence over the timeline of cuts, Russia has now promised to ‘speed up cuts’ to its oil production in line with other key members of OPEC. Saudi Arabia, along with main allies the UAE and Kuwait, have been at the forefront of this – having made deeper-than-promised cuts in January with plans to go a bit further in February. After looking a bit shaky – a joint Saudi Arabia-Russia meeting was called off at the recent World Economic Forum in Davos in January – the bromance of world’s two oil superpowers looks to have resumed. And with it, confidence in the OPEC+ club’s abilities.
Russia and Saudi Arabia both making new pledges on supply cuts comes despite supply issues elsewhere in OPEC, which could have provided some cushion for smaller cuts. Iranian production remains constrained by new American sanctions; targeted waivers have provided some relief – and indeed Iranian crude exports have grown slightly over January and February – but the waivers expire in May and there is uncertainty over their extension. Meanwhile, the implosion in Venezuela continues, with the USA slapping new sanctions on the Venezuelan crude complex in hopes of spurring regime change. The situation in Libya – with the Sharara field swinging between closure and operation due to ongoing militant action – is dicey. And in Saudi Arabia, a damaged power repair cable has curbed output at the giant 1.2 mmb/d Safaniuyah field.
So the supply situation is supportive of a rally, from both planned and unplanned actions. But crude prices are also reacting to developments in the wider geopolitical world. The USA and China are still locked in an impasse over trade, with a March 1 deadline looming, after which doubled US tariffs on US$200 billion worth of Chinese imports would kick in. Continued escalation in the trade war could lead to a global recession, or at least a severe slowdown. But the market is taking relief that an agreement could be made. First, US President Donald Trump alluded to the possibility of pushing the deadline by 2 months to allow for more talks. And now, chatter suggests that despite reservations, American and Chinese negotiators are now ‘approaching a consensus’. The threat of the R-word – recession – could be avoided and this is pumping some confidence back in the market. But there are more risks on the horizon. The UK is set to exit the European Union at the end of March, and there is still no deal in sight. A measured Brexit would be messy, but a no-deal Brexit would be chaotic – and that chaos would have a knock-on effect on global economies and markets.
But for now, the market assumes that there must be progress in US-China trade talks and the UK must fall in line with an orderly Brexit. If that holds – and if OPEC’s supply commitments stand – the rally in crude prices will continue. And it must. Because the alternative is frightening for all.
Factors driving the current crude rally:
Already, lubricant players have established their footholds here in Bangladesh, with international brands.
However, the situation is being tough as too many brands entered in this market. So, it is clear, the lubricants brands are struggling to sustain their market shares.
For this reason, we recommend an impression of “Lubricants shelf” to evaluate your brand visibility, which can a key indicator of the market shares of the existing brands.
Every retailer shop has different display shelves and the sellers place different product cans for the end-users. By nature, the sellers have the sole control of those shelves for the preferred product cans.The idea of “Lubricants shelf” may give the marketer an impression, how to penetrate in this competitive market.
The well-known lubricants brands automatically seized the product shelves because of the user demand. But for the struggling brands, this idea can be a key identifier of the business strategy to take over other brands.
The key objective of this impression of “Lubricants shelf” is to create an overview of your brand positioning in this competitive market.
A discussion on Lubricants Shelves; from the evaluation perspective, a discussion ground has been created to solely represent this trade, as well as its other stakeholders.Why “Lubricants shelf” is key to monitor engine oil market?
The lubricants shelves of the overall market have already placed more than 100 brands altogether and the number of brands is increasing day by day.
And the situation is being worsened while so many by name products are taking the different shelves of different clusters. This market has become more overstated in terms of brand names and local products.
You may argue with us; lubricants shelves have no more space to place your new brands. You might get surprised by hearing such a statement. For your information, it’s not a surprising one.
Regularly, lubricants retailers have to welcome the representatives of newly entered brands.
And, business Insiders has depicted this lubricants market as a silent trade with a lot of floating traders.
On an assumption, the annual domestic demand for lubricants oils is around 100 million litres, whereas base oil demand around 140 million litres.
However, the lack of market monitoring and the least reporting makes the lubricants trade unnoticeable to the public.
