Latest Oil Field Technology

Laversab, Inc. is a prime supplier of hazardous location computers, terminals and displays to the extremely demanding oilfield service industry. The cutting-edge technology that Laversab has created is among the most sophisticated and innovative technology in existence. Their innovative computers are Class 1, Div 1 and Div 2 certified by UL, certified for Zone 1 and 2 locations by ATEX as well as IECEx certified. The devices are built to survive in the most rugged and extreme of oilfield environments. Laversab Oilfield systems are in use in every corner of the world and under every possible climactic condition.

In the oilfield domain, new advances have appeared on the horizon. Here are six innovative ways experts hope will make the next oil spill less tragic.

1. A clay sponge to draw out oil and leave water behind

We reach for a sponge to clean up spills in our kitchens, so imagine what a giant one could do for a spill. While it seems like science fiction, researchers at Case Western Reserve University have developed a super-lightweight clay sponge to draw out oil from contaminated water. The extracted oil could then be recycled. The substance, which experts are calling an aerogel, is a freeze-dried mixture of clay with a polymer and air. It works in freshwater, salt water and on plain surfaces. Researchers are developing the sponge for further tests. You can learn more about aerogel here.

2. One boat to out-skim them all

Booms and skimmers are popular cleanup devices currently used in oil spills, but skimming cannot be done in rough, windy seas, nor is it effective at night when visibility is low. However, the company Extreme Spill Technology has developed a high-speed skimming vessel that the company claims can solve these issues. While traditional skimmers cannot successfully operate in waves higher than 1.5 meters, EST’s boat can skim in waves higher than 3 meters. The lightweight vehicles can operate faster than traditional skimmers, and the machines do not clog as easily. The boat has been successfully tested by the Canadian Coast Guard. As CEO David Prior shared with MNN, the company plans to sell the boats worldwide.

3. Magnetic soap may clean tainted water

One of the main “cleaners” on the Deepwater Horizon oil spill were dispersants. As we previously reported, almost 3 million liters of dispersants and soaps were used in the cleanup. However, dispersants are problematic because they do not easily break down in the environment. Scientists from the University of Bristol have developed a new, iron-rich salty soap that reacts to magnetic forces once it is in the water. The salts form a magnetic core when placed in a solution. When a magnetic force is applied, the core — with the oil — rises to the surface of the water. The research is still theoretical, but experts hope that it's the first step toward a new, important cleaning formula.

4. A special skimmer with groove technology

After the 2010 spill, Wendy Schmidt, president of the Schmidt Family Foundation, which works to create clean energy solutions, launched the Wendy Schmidt Oil Cleanup X CHALLENGE. The $1.4 million competition encouraged the best and brightest in the field of oil cleanup to present their solutions. The winner was Elastec/American Marine, an Illinois-based company that developed a kind of barrel skimmer than can separate oil from water, even in waves. The skimmer met the contest’s minimum requirement of an efficiency rate of 70 percent, skimming as much as 2,500 gallons per minute.

5. Kevin Costner’s oil filtration machine

When you think of Kevin Costner and water, you might picture the Oscar-winning actor sporting gills and swimming around an underwater ski lift. (See the actor’s 1995 watery post-apocalyptic film, "Waterworld.") However, it was the Gulf oil spill that revealed Costner’s greener side. Alongside his scientist brother Dan, Costner debuted an oil-filtration device that had been in development for more than a decade. As we previously reported, Costner has invested $26 million of his own money into a device that works on a centrifuge principle, separating and jettisoning clean water from oil. In 2011, it was revealed that British Petroleum had spent $16 million on the devices, even though they were shown to have failed initial field tests. While the devices show some promise, they became easily clogged with the heavier, sticker oils once in the field.

6. Peat moss mixture cleans up

Nature may soon mop up after our spills. Scientists in Norway have discovered that simple peat moss is an extremely good at absorbing oil. The company Kallak Torvstrøfabrikk is developing a product called Kallak Absorbent, which can be placed directly into the oil-soaked water. Ragnar Kallak, the company's founder, explained it to Science Daily: “[Peat moss] absorbs the oil on contact and encapsulates it. Water does not penetrate the peat moss, so the encapsulated oil is trapped in a non-sticky crust which is easily removed from the surface of the water.” Kallak Absorbent was deemed a success against a 2009 oil spill off the coast of Norway.
