Progressing Cavity Pumps (PCP): Recent Innovations

High-Temperature All-Metal PCPs

Traditionally, PCPs use elastomer stators, which degrade under heat. In thermal EOR, all-metal PCPs have shown strong performance. A 2019 field trial in Mexico with the PCM Vulcain™ confirmed their reliability in steam applications, handling high temperature without stator failure.

Outcome: Commercial validation for SAGD/steamflood projects – eliminates elastomer degradation risks.

Gas-Handling PCPs: Hydraulically Regulated (HRPCP)

In high gas wells, gas lock often kills conventional PCPs. The HRPCP design uses specialized geometry or valves to allow free gas flow. In East Africa, a well with 95% gas failed an ESP in 2 months; a PCM Slugger HRPCP ran over 755 days without failure.

Outcome: Extreme gas-handling capability – run-life increased by over 1,000%.

Rodless ESPCPs (Electric Submersible PCPs)

To deploy PCPs in deviated wells, operators use electric submersible PCPs, where a PMM drives the PCP rotor, eliminating rods. In West Africa, replacing gas lift with a KUDU ESPCP doubled production (+103%) and ran over 500 days continuously.

Outcome: Ideal for deviated, heavy-oil wells – combines PCP efficiency with ESP motor control.

Additional PCP Improvements

Incremental upgrades include:

• Better elastomers for chemical resistance

• Torque limiters and rod monitoring

• Standardized operating practices (e.g. Oman steamflood reliability program)

Outcome: PCPs now reliable in hotter, gassier, and more deviated wells.

Electric Submersible Pumps (ESP): Recent Innovations

Permanent Magnet Motors (PMMs)

Replacing induction motors, PMMs offer higher efficiency and lower heat. In heavy-oil offshore fields, PMM-ESPs improved uptime and energy use. One project saw a ~15% lower failure rate.

Outcome: Better performance in viscous and high-deviation wells.

Advanced Gas-Handling ESPs

Technologies like the MVP Centrilift™ and CHP (Contra-Helical Pump) handle >75% GVF and slugging. CHP keeps gas entrained, avoiding lock and ensuring stable flow.

Outcome: ESPs now work in conditions that once caused weekly shutdowns.

Rigless ESP Deployment

Retrievable ESP systems (e.g., AccessESP) allow slickline or coiled-tubing deployment through tubing. In Alaska, over 300 rig workovers were avoided using this technique.

Outcome: Lower downtime and costs – especially useful offshore or in remote fields.

Other ESP Improvements

• Upgraded seal sections for H₂S/CO₂

• High-temp motors for SAGD/geothermal

• Better penetrators and monitoring systems

Outcome: Modern ESPs can now achieve longer run times even in challenging wells.

Gas Lift (GL): Recent Innovations

High-Pressure Gas Lift (HPGL)

Field pilots with dedicated compressors (e.g. BPX Energy) show HPGL can match ESP performance. One test saw similar rates but cooler flow and less sand production than ESPs.

Outcome: HPGL extends gas lift into deeper or high-rate wells.

Next-Gen Gas Lift Valves

High-sensitivity valves deployed in China’s Fuling shale enabled lifting at ultra-low pressures. New designs with Monel bellows and carbide trims resist corrosion and wear.

Outcome: More reliable valve performance, especially in late-life wells.

Hybrid and Intermittent GL

Techniques like Plunger-Assisted Gas Lift (PAGL) or rigless dual-flow completions enable wells to switch between annular and tubing flow. Applied in Southeast Asia, this extended production without intervention.

Outcome: Greater flexibility and efficiency across a well’s lifecycle.

Rod Pumps: Recent Innovations

Stronger Surface Equipment

To handle long laterals and frac hits, vendors now offer 3,000–5,000 psi rated units. These use reinforced gearboxes, blowout preventers, and larger frame sizes.

Outcome: Rod lift now viable in high-load shale applications.

Downhole Components

New sand-tolerant plungers and gas separators like the WhaleShark™ improve pump fillage and reduce gas lock, especially in deviated wells.

Outcome: Extended run times and improved reliability in harsh wells.

Horizontal Well Adaptations

Use of continuous rod, fiberglass rod strings, and smart controllers have enabled rod lift in ultra-long laterals. One Canadian operator reported 21% increase in uptime with upgraded rod guides.

Outcome: Rod lift now feasible even in complex unconventionals.

---

Plunger Lift: Recent Innovations

Unconventional Gas Wells

New fast-fall, sealed, and multi-stage plungers allow effective lifting in horizontal shale wells. Optimized controllers improved production by ~7% in underperforming Marcellus wells.

Outcome: Plunger lift reestablished as a cost-effective tool in modern shale.

Gas-Assisted Plunger Lift (GAPL)

By injecting small volumes of gas during plunger cycles, operators in the Montney formation saved millions in injection gas and reduced downtime.

Outcome: Greater control and lower lifting cost in gassy wells.

Non-Traditional Completions

Plunger systems are now used in packer-completed and highly deviated wells with specialized plungers and bypass tubing.

Outcome: Expanded plunger lift envelope – not limited to vertical wells anymore.

Hybrid Lift Systems: Combined Solutions

Hybrid Type	Description	Outcome
ESP + Gas Lift	Lightens column, reduces pump stress	+30% production, lower power use, longer life
Rod Pump + Gas Assist	Injects gas to feed intake and separate gas	Improved fillage, lower BHP, fewer lockouts
Plunger + Gas Lift (PAGL)	Small gas injection to support cycles	Proven in 1,000+ wells, millions saved
ESPCP	ESP motor + PCP pump	Ideal for deviated, viscous, gassy wells

Hybrid systems have transitioned from experimental to commercial reality, delivering measurable gains in performance and economics.
