Oil & gas extraction in Indonesia’s mature fields continues to evolve as reservoir pressure declines, water-cut rises, and the downhole environment becomes more chemically aggressive. In these conditions, Sucker Rod Pumping (SRP) remains the most dependable artificial-lift solution due to its simplicity, high mechanical efficiency, and proven performance across a broad range of fluid viscosities.
To maintain production stability, operators rely on pump systems engineered to withstand solids, corrosion, temperature fluctuations, and long operating cycles. This is where PT. Endurance Lift Dynamics Indonesia (ELDI) provides strong support with its SRP Tubing Pump and SRP Insert Pump technologies—both designed to operate reliably in demanding extraction environments.
SRP for Mature Reservoir Performance
Across Sumatra, Java, and Kalimantan, SRP is widely utilized because it maintains drawdown even as wells enter late-life phases. Production engineers commonly face:
- Elevated solids content from sanding or scale
- Corrosive produced fluids from waterflood or chemical injection
- Higher bottom-hole temperature
- Unstable fluid levels requiring consistent mechanical displacement
Choosing the right pump design ensures optimal efficiency:
Tubing Pump (TP) delivers high displacement per stroke and structural strength, ideal for deeper or high-volume producers.
Insert Pump (IP) offers rapid retrieval and cost-efficient maintenance, especially in wells with frequent scale or solids issues.
ELDI combines advanced metallurgy and precision machining to create SRP pump systems that deliver durability and stable performance. Pump barrels use nitrided alloy steels, while plungers receive hard-chrome or carbide coatings to resist abrasive wear. Valve components are engineered for long-cycle reliability in harsh fluid environments.
Key performance attributes include:
- Superior chemical resistance, compatible with polymer, corrosion inhibitors, and high-salinity water.
- High thermal tolerance, ensuring stable pumping in elevated-temperature wells.
- Optimized pump clearances, reducing slippage and maintaining volumetric efficiency.
- Extended MTBF, lowering lifting cost and minimizing unplanned interventions.
These capabilities make ELDI SRP systems suitable for a wide range of primary and secondary recovery applications.
