A more thorough explanation:
Capture refers to the principle that gives ownership of certain things to the person who captures them. There are different applications of this principle:
- Rule of capture: This is a legal doctrine that applies to property. It states that wild animals belong to the person who captures them, even if they were originally on someone else's land. For example, if a hunter shoots a deer that was running on a neighbor's property, the hunter owns the deer.
- Water law: This is a principle that applies to groundwater. It states that a landowner can extract and use all the groundwater beneath their land, even if it affects other landowners' water supply. This principle has been limited or abolished by some laws.
- Oil and gas law: This is a principle that applies to oil and gas extraction. It states that a person who drills or pumps oil or gas from their land has no liability for draining oil or gas from under someone else's land, as long as they follow relevant laws and regulations.
- A fisherman catches a fish in a river that flows through different properties. The fisherman owns the fish, even if it was swimming in someone else's land.
- A farmer drills a well on their land and pumps water for irrigation. The water level in a nearby well owned by another farmer drops, and they can no longer use it. The first farmer has the right to use the groundwater under their land, even if it affects the other farmer's water supply.
- An oil company drills a well on their land and extracts oil. The oil comes from a reservoir that extends under a neighbor's land. The neighbor cannot claim compensation for the oil drained from their land, as long as the oil company follows relevant laws and regulations.
These examples illustrate how capture applies to different resources and situations. In each case, the person who captures the resource has the right to use it, even if it affects others. This principle can create conflicts between different landowners and users of natural resources, and laws and regulations may limit its application.
