dCRP Downhole ESP – Adaptive Multiphase Artificial Lift for Challenging Wells

The OTECHOS dCRP is a next-generation electric submersible pump (ESP) designed to deliver stable and efficient artificial lift in challenging well conditions.

As reservoirs mature, wells increasingly experience declining pressure, rising gas fractions, higher water cut, and sand production. Conventional ESP systems often struggle under these conditions, leading to reduced efficiency, wear, and frequent interventions.

The dCRP addresses these challenges through a low-speed rotary displacement principle that maintains stable volumetric efficiency across varying multiphase flow conditions. It is inherently tolerant to gas, liquids, and solids, enabling reliable operation where conventional ESPs lose performance or fail.

Designed for durability and uptime, the dCRP eliminates key failure drivers: no impellers exposed to erosion, no valves, and high tolerance to sand and dry running. This significantly reduces wear and extends operational lifetime.

An adaptive control system continuously adjusts to changing well conditions, optimizing production as reservoir characteristics evolve over time.

The compact and modular design supports flexible deployment, including wireline-retrievable configurations and compatibility with standard completion systems.

By stabilizing production and reducing failure risk, the dCRP enables increased recovery from existing wells while lowering total cost of ownership.
