Reliable Production

The Evolving Landscape of Oil Production
Modern oilfields have moved far beyond the rugged operations of the past. With advanced
drilling, real-time monitoring, and optimized production strategies, today’s wells are
engineered for precision. Yet one reality hasn’t changed—most wells cannot sustain natural
flow indefinitely. When reservoir pressure declines, artificial lift systems become critical to
keeping hydrocarbons moving to the surface.

Artificial Lift: The Lifeline of Production
In the early life of a well, reservoir pressure is sufficient to drive fluids to surface. Over time,
however, this energy depletes, causing production to slow or stall. Artificial lift reduces
bottomhole pressure, assists fluid movement, and maximizes recovery. In essence, it is the
heartbeat of a well—keeping it alive long after natural flow subsides.

Plunger Lift: Simple and Sustainable
Plunger lift remains one of the most efficient artificial lift methods for marginal or gas-
dominant wells. It uses natural reservoir pressure to push a plunger upward, carrying
accumulated liquids with it.

Advantages of plunger lift:
 Low energy requirements
 Few moving parts and minimal maintenance
 Environmentally friendly operation
This simplicity makes plunger lift a cost-effective solution for extending well life and
improving returns.

Gas Lift Valves: Precision Flow Control
Gas lift valves (GLVs) are central to gas injection systems. By regulating controlled volumes
of gas into the tubing, they reduce fluid density and enable hydrocarbons to rise more
easily.

Benefits of gas lift valves:
 Precise control of gas injection
 Improved lifting efficiency
 Stable, predictable production performance
Reliability and accurate calibration of GLVs are essential, as poorly tuned valves can
compromise the entire gas lift process.

2. Gas Lift Mandrels: Long-Term Reliability
Gas lift mandrels form the backbone of gas lift systems, securely housing the valves within
the tubing string. They provide structural integrity, enable smooth installation, and simplify
maintenance throughout the well’s lifecycle.

Key advantages of mandrels:
 Long-term durability under demanding conditions
 Adaptability across well phases
 Support for efficient recovery strategies
Together, mandrels and valves create a dependable artificial lift system that enhances
production while extending well life.

The Bigger Picture: Reliability and Sustainability
Today’s oil production is about more than just maximizing flow—it is about sustainability,
efficiency, and long-term asset value. Artificial lift systems provide operators with the
flexibility to adapt to changing reservoir conditions, reduce operating costs, and maximize
recovery.

Conclusion
Every modern oilfield requires a reliable artificial lift system to sustain production. From the
efficiency of plunger lift systems to the precision of gas lift valves and the durability of
mandrels, these technologies ensure wells remain productive, economical, and efficient.
Without artificial lift, production declines prematurely; with it, reservoirs can be fully
developed, costs controlled, and energy reliably delivered.
