ARTIFICIAL LIFT

Sucker Rod Pumping (SRP) is one of the most widely used artificial lift methods, known for its simplicity, reliability, and cost-effectiveness in low-flow and mature wells. Utilizing a positive displacement mechanism, SRP operates efficiently under low bottom-hole pressure conditions, making it a trusted fallback when other lift methods fail.

How SRP Works

SRP systems use a reciprocating pump installed downhole, driven by a surface pumping unit connected through a string of sucker rods. As the rod string moves up and down, the pump lifts fluid from the reservoir to the surface, ensuring steady production even in wells with low gas-liquid ratios or high viscosity crude.

Key Components of an SRP System:

Surface Pumping Unit – Provides the mechanical motion required for fluid lift.

Control Panel – Regulates and optimizes pump operations for maximum efficiency.

Sucker Rods – A rod string connecting the surface unit to the downhole pump, transferring motion.

Downhole Pump – A reciprocating pump that lifts reservoir fluids to the surface.

Why Choose SRP?

Proven Performance – Decades of field use in conventional, unconventional, and mature wells.

Cost-Effective – Low operational and maintenance costs compared to other artificial lift systems.

Versatile Application – Suitable for shallow to moderately deep wells in onshore and offshore environments.

Durable & Reliable – Long service life with proper maintenance and optimized pump operation.

Handles High Viscosity & Sand Production – Effective in heavy oil wells and environments with solids production.

Progressive Cavity Pumps (PCPs) are a highly efficient positive displacement artificial lift solution, ideal for handling viscous fluids, high sand & solid content, and fluctuating flow rates. Known for their simplicity and durability, PCP systems offer low shear, gentle fluid handling, making them a preferred choice for CBM, heavy oil, and multiphase production wells.

How PCP Works

A progressive cavity pump consists of a rotor and a stator, creating sealed cavities that move fluid smoothly and continuously to the surface. The rotational motion generated by a surface drive system enables efficient fluid displacement, reducing gas interference and handling high solids content better than conventional pumps.

Key Components of a PCP System:

Surface Drivehead – Provides rotational energy to drive the pump.

Control Panel – Optimizes pump performance and protects against overloading.

Rod String – Transfers torque from the drivehead to the downhole pump.

Downhole PCP Pump – A rotor-stator assembly that lifts fluid through continuous displacement.

Why Choose PCP?

Handles High Sand & Solids Production – Superior to other lift methods in abrasive environments.

Low-Shear Fluid Handling – Minimizes emulsion formation, preserving fluid integrity.

Energy-Efficient & Cost-Effective – Requires less energy compared to other artificial lift methods.

Ideal for CBM, Heavy Oil, & Multiphase Wells – Effective in low-pressure reservoirs and dewatering applications.

Simple Maintenance & Long Service Life – Fewer moving parts result in lower operating costs and reduced downtime.

Electrical Submersible Pumps (ESPs) are one of the most efficient artificial lift solutions for high-volume fluid production in moderate to deep wells. Designed to handle high flow rates, high water cuts, and varying well conditions, ESPs provide continuous, automated operation, making them a preferred choice for CBM, conventional oil, and water-heavy reservoirs.

How ESP Works

An ESP system consists of a multistage centrifugal pump powered by a submersible motor, installed deep inside the well. The motor drives the pump, creating the pressure required to lift large volumes of fluid to the surface. Variable frequency drives (VFDs) can be used to optimize speed and adjust performance based on well conditions.

Key Components of an ESP System:

Submersible Motor – Powers the pump and is designed to withstand extreme downhole conditions.

Pump – A multistage centrifugal pump that lifts fluids from the reservoir.

Gas Separator – Prevents excessive gas from entering the pump, improving efficiency in gassy wells.

Power Cable & Motor Lead Extension – Supplies electricity to the motor from the surface.

VFD Controller – Adjusts pump speed for optimal performance and energy efficiency.

Why Choose ESP?

High Flow Rate Capability – Handles large production volumes, ideal for high-water-cut and high-permeability reservoirs.

Efficient in Deep Wells – Suitable for wells deeper than other artificial lift methods can reach.

Automated & Remote Monitoring – Can be integrated with real-time monitoring systems for optimized well performance.

Versatile Application – Effective in oil, gas, CBM, and geothermal wells, as well as high-water disposal operations.

Long Service Life – Proper design and optimization extend ESP run life, reducing workover costs.

Gas Lift is a highly effective artificial lift method that utilizes injected gas to reduce the density and hydrostatic pressure of wellbore fluids, allowing reservoir energy to lift production to the surface. Ideal for high-gas, high-deviation, and deep wells, Gas Lift provides a flexible, cost-effective solution with minimal downhole moving parts, making it a low-maintenance option for long-term operations.

How Gas Lift Works

Gas is injected into the annulus and enters the tubing through gas lift valves installed at different depths. The injected gas mixes with the produced fluid, reducing its density and allowing formation pressure to push the fluid to the surface. The system can be optimized dynamically based on production needs, making it one of the most adaptable artificial lift methods.

Key Components of a Gas Lift System:

Gas Lift Mandrels – Holds and positions gas lift valves along the tubing string.

Gas Lift Valves – Controls gas injection into the tubing at specific depths.

Injection Gas Source – Provides the gas required for lifting production fluids.

Surface Control System – Regulates injection pressure and gas flow rate for optimal performance.

Why Choose Gas Lift?

Handles High Gas-to-Liquid Ratios (GLR) – Well-suited for gassy reservoirs where other lift methods may struggle.

Ideal for Deep & Deviation Wells – Works effectively in high-angle and horizontal wells where mechanical lift systems are impractical.

Minimal Downhole Equipment & Low Maintenance – Reduces intervention costs compared to rod-driven lift systems.

Flexible & Scalable – Injection rates and depths can be adjusted dynamically to adapt to changing well conditions.

Long Operational Life – With proper gas supply and system optimization, Gas Lift provides years of efficient production.
