Technology Platform

One Platform. Four Technology Pillars.

Thermal systems, water systems, downhole delivery, and digital intelligence integrated to improve energy production performance.

Nakasawa’s technology platform is built around the full thermal recovery chain: preparing the water, generating high-quality steam, preserving heat into the well, monitoring operations, and optimizing performance over time. This is not a fragmented equipment catalogue. It is an integrated energy recovery platform.

Platform Overview

Four pillars. Each one owns a stage of recovery.

Every pillar contributes a distinct capability to the thermal recovery chain.

How the Four Pillars Work Together

One integrated recovery chain.

Each stage depends on the one before it. Performance is set by how well the stages connect, not by any single machine.

Better water means better steam. Better steam means better recovery performance.

Specifications, benefits, and applications for every pillar, in chain order.

Pillar 01

Water Treatment Systems

Reliable steam generation begins with reliable water treatment. Nakasawa develops systems that condition, filter, and prepare water for demanding thermal operations, protecting critical equipment and reducing operating risk.

Technical Specifications

Up to 10,000 ppm TDS

Feedwater Quality Standard (Treatment Capability)

Up to 12.5 TPH

Flow Capacity

Project-specific

Recovery Rate

Pillar 02

Thermal Recovery Systems

Nakasawa develops thermal recovery systems designed to improve heat generation, steam quality, energy efficiency, and recovery performance.

Our thermal systems support applications such as Cyclic Steam Stimulation, Steam Flood, heavy oil recovery, industrial steam, and future geothermal opportunities.
