Case Studies
We have successfully deployed the IntelliCPCP® intelligent conical progressive cavity pump system across multiple Sinopec oilfields, including Shengli, Henan, and Zhongyuan. Across all projects, MTBF increased by 45.63%, cumulative cost savings and efficiency gains reached USD 606,300, and the longest pump inspection cycle achieved 4,710 days — significantly enhancing oilfield production efficiency and economic performance.

Sinopec Shengli – Xinchun
CSS in Shallow, Highly Deviated Extra-Heavy Oil Wells
Core Challenges
- Highly deviated well geometry limits rod pump setting depth; severe rod-tubing wear with minimal string optimization margin.
- Frequent rod float during late-stage production restricts cyclic production capacity.
- Post-steam pump sticking and fluid leakage necessitate frequent flushing and workover interventions.
- Premature cycle switching reduces overall OSR and constrains well productivity.
- Fatigue loading on Type-5 pumping units due to rod float overload poses safety risks.
Sinopec Henan – Nanyang
CSS in Shallow Extra-Heavy Oil Marginal & Low-Productivity Wells
Core Challenges
- Declining fluid temperature in late-stage CSS causes severe pump intake difficulties, reducing OSR.
- Rod-tubing wear limits average sucker rod lifespan to < 1.5 years.
- Sand-induced pump sticking.
- Existing tubing string prevents integrated injection-production without removal.
Sinopec Shengli – Binnan
CSS in Medium-Deep Extra-Heavy Oil Wells
Core Challenges
- Cycle switching requires tubing removal; heavy insulated tubing poses high operational risk.
- Late-stage rod float restricts cyclic production capacity.
- Severe fluid leakage results in low system efficiency.
- Frequent cycle switching reduces OSR and constrains productivity.
- Conventional surface facilities demand frequent maintenance.
Sinopec Zhongyuan – Neimeng
Combined CCUS and Electrical Heating Lift in Medium-Deep Highly Deviated Wells
Core Challenges
- Electrical heating with conventional pumping units drives high power consumption and OPEX.
- No tubing-free cycle switching — low heat utilization efficiency.
- Wellbore temperature fluctuations cause viscosity surges, hindering pump intake at low temperatures.
- Severe rod-tubing wear shortens MTBF and increases maintenance frequency.
Sinopec Shengli – Gudong
Cold Production of Conventional Heavy Oil in Medium-Deep Wells
Core Challenges
- Sand-induced pump sticking.
- Excessive rod string lifting loads.
- Sustained production unachievable even with chemical drag-reducing agents.
