Introduction

The production stage is the most important stage of a well's life, when the oil and gas are produced.
By this time, the oil rigs used to drill and complete the well have moved off the wellbore, and the top is usually outfitted with a collection of valves called a Christmas tree or
Production trees.
These valves regulate pressures, control flows, and allow access to the wellbore in case further completion work is needed. From the outlet valve of the production tree, the flow can be connected to a distribution network of pipelines and tanks to supply the product to refineries, natural gas compressor stations, or oil export terminals.



As long as the pressure in the reservoir remains high enough, the production tree is all that is required to produce the well.



If the pressure depletes and it is considered economically viable, an artificial lift method can be employed.

Flowing Wells

Defined as any well which has sufficient pressure in the reservoir to cause the oil or gas to flow naturally to the surface through the wellbore.
A well which produces oil or
