Traditional Vs. Modern Oil Mining Techniques

Traditional Vs. Modern Oil Mining Techniques – Direct lithium extraction promises more lithium, is cheaper, faster and uses far less land than traditional brine evaporation processes. Volt’s system is particularly suitable for brine with a low concentration

Canadian company Volt Lithium has developed and pilot-tested a new low-cost lithium extraction method to extract this important battery metal from low-concentration brines. Now there are plans to convert old oil fields into lithium production operations.

Traditional Vs. Modern Oil Mining Techniques

As the global transition to electric vehicles accelerates and power grids around the world shift to massive batteries to balance demand against intermittent supplies of renewable energy, the world will need unprecedented amounts of lithium to feed its insatiable hunger for batteries .

Offshore Oil & Gas

We’ve already written that many people expect a lithium shortage in the coming decade; For example, it takes about 13 years to start a new mining operation, and the International Energy Agency estimates that existing mines and brine projects, as well as mines and brine projects currently under construction, will only meet about half of expected demand.

According to an April report from Goldman Sachs, direct lithium extraction (DLE) offers a “potentially revolutionary” way to quickly and cost-effectively increase production from brine, “much like shale has done for oil.”

The typical way to extract lithium from salty groundwater brine is to pump it up from underground and then store it in huge ponds on the surface. Over a year or more, the sun gently evaporates the water until the lithium concentration can be precipitated with chemical reagents and processed into lithium carbonate or hydroxide for sale. This allows you to recover 40-60% of the lithium in your brine at a price between $3,300 and $4,900 per barrel. metric ton of lithium carbonate equivalent.

The DLE process is much faster, taking just a few hours instead of more than a year. It can extract up to twice as much lithium from a given brine as an evaporation process, potentially doubling the output of a given brine operation. It uses around 95% less land and is economically viable with significantly lower lithium concentrations in the brine. And it costs less per ton of lithium carbonate equivalent than evaporation.

The DLE process essentially adds a highly selective absorption molecule to salt water that captures the lithium, quickly separating it from the water and eliminating contaminants in the process.

Calgary-based Volt Lithium is one of many companies advancing this potentially groundbreaking technology. Volt announced earlier this year that its pilot program had managed to recover 90% of lithium from concentrations as low as 34 mg/liter and an outstanding 97% from concentrations as high as 120 mg/liter.

The latter number is significant because it represents the lithium concentration in the brine beneath the Company’s 430,000 acre property in Rainbow Lake, Alberta. This is an old, depleted oil field with more than 1,300 wells pre-drilled on site to provide easy access to brine. Volt estimates that about 4.9 million tons of lithium carbonate equivalent can be mined there, and that it can be done for about $3,000 per ton. tons and pump out around 20,000 tons per year.

“This technological discovery opens up more oilfield reservoirs across North America that can now enable commercial lithium recovery using Volt’s proprietary DLE process,” the company said in a press release. The press release also notes that relatively simple process improvements, such as optimizing reagent usage, should further reduce costs. The company is in the process of building its first permanent pilot plant.

The Science Behind Attar Extraction

According to Goldman Sachs, brine accounts for about two-thirds of the world’s lithium resources, but only about 40% of current production. If DLE technologies are implemented in 20-40% of brine operations in Latin America and their yields conservatively increase from about 50% to about 80%, Goldman Sachs estimates that this would add 70-140,000 tons of lithium to the market by 2028 costs, which increased global crude oil supply by around 8%.

That’s not enough to meet expected demand in 2030, but it also doesn’t take into account the new opportunities for oil field production in North America, Asia and Europe that new technologies like Volt are opening up.

Drilling mud, in petroleum engineering, a heavy, viscous fluid mixture used in oil and gas drilling to transport rock chips to the surface and also to lubricate and cool the drill bit. Through hydrostatic pressure, the drilling mud also helps to prevent unstable layers from sinking into the borehole and water from penetrating from any existing aquifers.

Drilling mud is traditionally water based, either freshwater, seawater, naturally occurring brines or treated brines. Many sludges are oil-based and use direct products from oil refining, such as diesel oil or mineral oil, as the liquid matrix. In addition, various so-called synthetic sludges are made from highly refined liquid compounds, the properties of which are more precise than traditional petroleum-based oils. In general, water-based muds are sufficient for less demanding drilling of traditional vertical wells at intermediate depths, whereas oil-based muds are better suited for greater depths or for directional or horizontal drilling, which places greater stress on the drilling rig. Synthetic-based drilling fluids were developed in response to environmental concerns over oil-based fluids, although all drilling fluids are highly regulated in their composition and in some cases certain combinations are banned for use in certain environments.

A typical water-based drilling mud contains a clay, usually bentonite, to give it sufficient viscosity to carry drill cuttings to the surface, as well as a mineral such as barite (barium sulfate) to increase the weight of the column sufficiently to facilitate drilling stabilize. Smaller amounts of hundreds of other ingredients may be added, such as caustic soda (sodium hydroxide) to increase alkalinity and reduce corrosion, salts such as potassium chloride to reduce the penetration of water from the drilling fluid into the rock formation, and various petroleum-derived ingredients Drilling lubricants. Oil and synthetic slurries contain water (usually a salt solution), bentonite and barite for viscosity and weight, and various emulsifiers and detergents for lubricity.

Drilling mud is pumped through the hollow drill pipe to the drill bit, where it exits the pipe and is then flushed back to the surface through the borehole. For economic and environmental reasons, oil- and synthetic-based sludges are typically cleaned and recycled (although some sludges, particularly water-based sludges, may be released into the environment in a regulated manner). Larger chips are removed by passing the recycled sludge through one or more vibrating screens, and sometimes fine chips are removed by passing the sludge through centrifuges. Cleaned mud is mixed with new mud and recycled downhole. Century. Using drills attached to bamboo poles, they dug wells about 800 feet (240 m) deep. The extracted oil was transported via bamboo pipelines and used for early lighting and heating.

The effects of the Industrial Revolution lead to increased demand for a cheaper and more efficient fuel than coal. This demand led to Colonel Edwin Drake’s famous oil discovery in Pennsylvania in 1859, which marked the first commercial drilling in North America. The first modern wells were drilled using a “cable tool” system that was lifted and dropped to the ground to create a borehole. The year 1901 marks the most famous and influential oil well drilled in the Spindletop Oilfield in southeast Texas. The success of this oil field influenced the introduction and popularity of the rotary drilling system, which became the globally recognized drilling method of choice. In parallel with the introduction of the rotary drilling system, other key technologies were developed, such as the introduction of the derrick/haul system, the tricone drill and the first documented use of drilling mud.

Vertical drilling is considered a traditional drilling method for accessing deposits just below the surface. Once the only method of producing oil and gas, vertical drilling has become a less common drilling method due to the development of horizontal and directional drilling technologies. Vertical wells are considered simple and provide initial cost savings because they require less equipment and labor. In larger
