The different types of oil wells

If the drilling results are conclusive, the well is put into production in two phases:

Primary production

At the beginning of the life of the well, the pressure at the oil reservoir is important, as the oil can reach the surface naturally (this is called an eruptive well). The flow then weakens rapidly, and the well no longer produces spontaneously (a non-eruptive well). Pumps are then put in place to raise the oil and continue the well’s operation. 

Secondary production

As the oil is produced, the pressure drops inside the reservoir. In order to stabilize this pressure and replace the volumes of oil extracted, water (which is produced with the oil) is injected from the reservoir into the deposit, through water injection wells. The injection points are carefully selected to maintain the pressure in the rocks containing the hydrocarbon and to sweep them to the producing wells.
In this second phase of the oil field’s life, the extracted fluid has more and more water as time passes.

There are, therefore, two types of wells: oil producing wells and water injection wells.

The optimal production of a deposit often requires up to 10 or 15 years. In addition, the production of a large deposit is spread over several decades, with the implementation of different techniques as the field ages.
