OBJECTIVES

After detection of that the natural drive energy of the reservoir was not strong enough to push desired oil flow from the AZ-028 well to the surface, our client (NISOC) attempted to recover more production.

The primary objective for our client and our team became to achieve desired flow rate on a continuous basis from the AZ-038 well and indeed making sure that no harm is done to the reservoir. The AZ-028 well has been drilled in 1970 and after many years of production, the well flow rate decreased to only 100 barrels of oil per day and the water cut raised to 20%. After a lot of research, simulations other types of engineering work, our team recommended the best method and unit to be implemented for this well

SOLUTIONS

PETRO EDMAN engineers team recommended a Sucker Rod Pumping (SRP) unit to be installed on the AZ-038 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, first ultra-long stroke pumping unit with stroke length of 366 inches and lifting capacity of 50klb has been installed on this well.

RESULTS

After the downhole pump installation (2024 September) and testing of the downhole pump, the downhole performance has been approved and after the surface pumping unit installation, the production will raise from 100 barrels of crude oil per day (before pump installation) to a stunning continuous rate of 1500 bbl/day.

CHALLENGES
