Pad Drilling: Innovation in the Oil and Gas Industry

Pad drilling is minimizing the oil industry’s footprint while boosting efficiency:

Pad Drilling Innovation in the Oil Industry

This infographic details one of the most significant innovations in the oil and gas industry in recent times, pad drilling.

Essentially, pad drilling is the practice of drilling multiple entry points into wells from a single surface location. Prior to the discovery of pad drilling, an operator would drill a single well, disassemble the drilling rig, move it to a new location, and then repeat the process. Pad drilling allows up to twenty or more wells to be drilled from a single drilling location.

This innovative technique reduces drilling cycle time and the overall cost of operating wells, while leaving a smaller footprint on the surface of the well. Also, fewer access roads need to be constructed and fewer trucks to carry the materials, further reducing the environmental impact.

Pad drilling originates from offshore drilling and gained notoriety with its onshore counterpart as recently as 2004. In the U.S.A., the number of pad drilling wells grew by a factor of four, just since 2012.

Charted: Global Uranium Reserves, by Country

We visualize the distribution of the world’s uranium reserves by country, with 3 countries accounting for more than half of total reserves.

There can be a tendency to believe that uranium deposits are scarce from the critical role it plays in generating nuclear energy, along with all the costs and consequences related to the field.

But uranium is actually fairly plentiful: it’s more abundant than gold and silver, for example, and about as present as tin in the Earth’s crust.

We visualize the distribution of the world’s uranium resources by country, as of 2021. Figures come from the World Nuclear Association, last updated on August 2023.

Ranked: Uranium Reserves By Country (2021)

Australia, Kazakhstan, and Canada have the largest shares of available uranium resources—accounting for more than 50% of total global reserves.

But within these three, Australia is the clear standout, with more than 1.7 million tonnes of uranium discovered (28% of the world’s reserves) currently. Its Olympic Dam mine, located about 600 kilometers north of Adelaide, is the the largest single deposit of uranium in the world—and also, interestingly, the fourth largest copper deposit.

Despite this, Australia is only the fourth biggest uranium producer currently, and ranks fifth for all-time uranium production.

Figures are rounded.

Outside the top three, Russia and Namibia both have roughly the same amount of uranium reserves: about 8% each, which works out to roughly 470,000 tonnes.

South Africa, Brazil, and Niger all have 5% each of the world’s total deposits as well.

China completes the top 10, with a 3% share of uranium reserves, or about 224,000 tonnes.

A caveat to this is that current data is based on known uranium reserves that are capable of being mined economically. The total amount of the world’s uranium is not known exactly—and new deposits can be found all the time. In fact the world’s known uranium reserves increased by about 25% in the last decade alone, thanks to better technology that improves exploration efforts.

Meanwhile, not all uranium deposits are equal. For example, in the aforementioned Olympic Dam, uranium is recovered as a byproduct of copper mining occurring at the same site. In South Africa, it emerges as a byproduct during treatment of ores in the gold mining process. Orebodies with high concentrations of two substances can increase margins, as costs can be shared for two different products.
