Petropedia explains Pay Zone
A pay zone contains a reservoir or a portion of reservoir that has been identified as an area from where large amount of hydrocarbons can be extracted. Such an area or zone is known as a high exploitable zone and is a favorable location for any oil and gas exploration and production organization. A producing zone once found is capable of paying all the expenses that an oil and gas E&P organization will incur on developing such zone as well as make them earn good revenues and profits.
