Closed In Well
Definition - What does Closed In Well mean?
When a well is shut down with a valve to halt the production, it is called as closed-in well. It is also referred to as shut-in well. All oil and gas wells are, at some point closed down for a specific period of time to allow them to undergo stabilization. The period of stabilization for a well during a closed phase allows the well to steady its pressure. While a closed-in well is under stabilization, its constant pressure determines the starting point for a well test for the next round of production.
Petropedia explains Closed In Well
Oil wells are drilled and put into a production phase. Drilling crew works on the well round the clock and produces oil from the reservoir. Every oil well has pressure build up in them and due to regular extraction, these oil wells need to be shut down for a certain period of time to undergo stabilization. When the oil well is closed with a valve to put a pause to the production, the well is referred to as a closed-in well. Every well is closed for stabilization and a valve plays an important role in enclosing the entrance, thus shutting it off for the manufacture.
