OBJECTIVES
After the AZ-028 well had been plugged and abandoned for many years, and with artificial lift methods becoming more popular in Iran—along with many successful installations by Petro Edman Company—our client (NISOC) decided to re-complete the well and resume oil production.
The primary objective for our client and our team was to achieve the desired flow rate on a continuous basis from the AZ-028 well while ensuring that no harm was done to the reservoir. The AZ-028 well was originally drilled in 1963 and, after many years of production, it was plugged and abandoned. Following extensive research, simulations, and other engineering analyses, our team recommended the most suitable method and equipment to be implemented for this well.
SOLUTIONS
The engineering team at PETRO EDMAN recommended the installation of a Sucker Rod Pumping (SRP) unit on the AZ-028 well. To maximize equipment lifespan while achieving the desired flow rate, it was essential to operate the pump as slowly as possible, using the minimum number of strokes. Consequently, an ultra-long stroke pumping unit—featuring a stroke length of 366 inches and a lifting capacity of 50,000 lbs—was installed on the well.
RESULTS
Following the installation and testing of the downhole pump in August 2024, the system’s performance was validated. After completing the installation of the surface pumping unit, production increased to an impressive and continuous rate of 1,500 barrels per day (bbl/day).
