OBJECTIVES
After a long time of production in “Masjed Soleyman” oil field (the first
discovered oil field in Middle East) the natural drive energy of the
reservoir was not strong enough to push desired oil flow from the
reservoir 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 reservoir and indeed
making sure that no harm is done to the reservoir. After a lot of
research, simulations and other types of engineering work, our team
recommended the best method and unit to be implemented for the
MIS-335 new drilled well.
SOLUTIONS
PETRO EDMAN engineers team recommended a Sucker Rod Pumping
(SRP) unit to be installed on the MIS-335 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, and using the most durable
downhole equipment to withstand the corrosion of acidic fluid of the
well. Therefore, first long stroke pumping unit with stroke length of 306
inches and lifting capacity of 50klb has been installed on this field.
RESULTS
After the pumping unit installation (2024 June) and commissioning, the
system performance has been analyzed and the production steadily
raised from zero barrels of crude oil per day (before pump installation)
to a stunning continuous rate of 800 bbl/day.
CHALLENGES
• Hazardous Well Fluid (High
𝐻2𝑆 Content)
• Optimized installation (Only
13 meters Above Perforations)
• 800bbl/day flow rate
• Harsh environment
BENEFITS
• Cost-effective
• Highly Durable Materials
• High Strengths Rod String
• No harm to the reservoir
• Less maintenance compared
to other artificial lift methods
• Higher flow rates with less
speed
• Smart monitoring with
EDControl and Dynamometer
