On-Pump

On-Pump: A lifeline for Oil & Gas Production

In the world of oil and gas, "on-pump" refers to a critical technique employed to revive production from wells that have ceased flowing naturally. As oil and gas reservoirs deplete, pressure within the reservoir drops, leading to a decline in production. This is where the "on-pump" solution comes into play.

Here's how it works:

• Artificial Lift: "On-pump" utilizes artificial lift methods to bring fluids from the well to the surface. These methods essentially create a "pump" to overcome the decreasing reservoir pressure and maintain production.
• Common Techniques: Several techniques fall under the umbrella of "on-pump," each with its own advantages and applications:
  • Electric Submersible Pumps (ESPs): These pumps are submerged in the wellbore and use electric motors to drive the fluid to the surface. ESPs are known for high efficiency and are commonly used in wells with a high water cut.
  • Rod Pumps: These are traditional pumps where a sucker rod is connected to a pump downhole. The rod is driven by a surface motor, creating a reciprocating motion that lifts the fluid. Rod pumps are versatile and suitable for various well conditions.
  • Progressive Cavity Pumps (PCPs): These pumps are known for their ability to handle high viscosity fluids and are often used in wells with heavy oil or gas-condensate production.
  • Gas Lift: In this technique, compressed gas is injected into the wellbore, reducing the pressure gradient and assisting in lifting fluids to the surface.

Benefits of On-Pump:

• Sustained Production: On-pump allows for continued production from wells that would otherwise be shut-in, extending the lifespan of the reservoir.
• Increased Efficiency: By optimizing the pumping system, operators can increase the efficiency of fluid recovery.
• Cost-Effectiveness: Despite the initial investment, on-pump technology can be a cost-effective solution compared to drilling new wells.

Challenges of On-Pump:

• Installation and Maintenance: Installing and maintaining artificial lift systems can be complex and require specialized expertise.
• Equipment Failure: Pump failures can lead to downtime and production losses.
• Wellbore Integrity: Wells that have been shut-in for extended periods may require workover operations to ensure wellbore integrity before installing an artificial lift system.

Conclusion:

On-pump technology plays a crucial role in maintaining and optimizing oil and gas production from mature fields. By overcoming the limitations of declining reservoir pressure, these techniques allow operators to maximize recovery and extend the economic life of their assets. As the oil and gas industry continues to explore new ways to access and produce hydrocarbons, on-pump solutions will remain essential tools for maximizing production and ensuring the long-term viability of oil and gas operations.
