OBJECTIVES
After detection of that the AZ-461 well has reached to the inactive phase of life cycle and natural flow of the well is not sufficient, our client (NISOC) attempted to increase the production and set the well as an active well again.
The primary objective for our client and our team became to achieve desired flow rate on a continuous basis from the AZ-461 well and indeed making sure that no harm is done to the reservoir. After a lot of research, simulations other types of engineering work, our team recommended the best method and unit to be implemented again by our team in Iran.
SOLUTIONS
PETRO EDMAN engineers team recommended a Sucker Rod Pumping (SRP) unit to be installed on the AZ-461 well. In order to maximize the life of the equipment while achieving the desired flow rate, it is desirable to pump as slowly as possible, using the minimum number of strokes. Therefore, an ultra-long stroke pumping unit with stroke length of 366 inches and lifting capacity of 50klb has been installed on this well.
