b) Multistage centrifugal pump
Task: A newly drilled oil well has been discovered with high production potential. The well is located in a remote area with limited access to electricity, but the reservoir is at a relatively low pressure. You are tasked with choosing the best lifting method for this well.
Requirements:
Exercice Correction:
Although ESPs are known for their high efficiency and production rates, they are not the ideal choice for this scenario. The limited access to electricity poses a major challenge, as ESPs require a reliable power source to operate. Additionally, other methods like beam pumps might be more suitable for low-pressure reservoirs, especially if the well is located in a remote area.
Therefore, a beam pump would be a more suitable lifting method in this case. Beam pumps are known for their reliability in low-pressure conditions and can operate effectively without a constant power supply. They also require less specialized infrastructure, making them a practical choice for remote locations.
