What are oil zones?

Residual oil zones, called ROZs, are areas of immobile oil found below the oil-water contact of a reservoir. ROZs are similar to reservoirs in the mature stage of “waterflooding,” in which water has been injected into a formation to sweep oil toward a production well.

Where are the main oil fields located?

How do I find oil fields?

The search for crude oil begins with geologists who study the structure and history of rock layers below the earth’s surface to locate areas that may contain deposits of oil and natural gas. Geologists often use seismic surveys on land and in the ocean to find the right places to drill wells.

In the UK there are now 120 onshore oil and gas sites with 250 operating wells producing between 20,000 and 25,000 barrels of oil equivalent a day. UKOG is operating primarily in the Weald Basin, in South East England, which has a long tradition of oil and gas exploration.

Can I drill for oil on my property?

That’s legal in many jurisdictions under what’s called the “rule of capture,” meaning anything you can produce from a well on your property is yours, even if it drains from somewhere else. If your neighbors don’t like it, they can drill their own wells—unless, of course, they’re too late.
