Capabilities
Unionlever Oilfield Equipment (OFS) serves as the Group’s dedicated oilfield equipment division, integrating engineering coordination, API-compliant manufacturing, independent quality control, and global supply chain capabilities to deliver reliable, field-ready solutions worldwide.
Engineering Capability – Overview
At Unionlever Oilfield Equipment (OFS), engineering is a core in-house capability rather than a function outsourced entirely to factories.
Our engineering work is carried out by Unionlever OFS’ own engineering team, working in close coordination with selected manufacturing partners. This structure allows us to support projects from early technical discussions through final production, ensuring design intent, manufacturability, and field application requirements are fully aligned.
Our engineering capabilities are developed under Unionlever International Group (Hong Kong), established since 2008, combining accumulated design experience with practical field requirements from global drilling operations.
Unionlever Engineering Capability
Unionlever OFS engineering supports the full lifecycle of oilfield tools and well control equipment, including:
● Product design based on API specifications and real operating conditions
● Structural and pressure design for critical well control and downhole tools
● Material selection aligned with temperature, pressure, corrosion, and service environment
● Thread and connection compatibility with international standards
● Rigorous testing procedures to ensure performance and reliability under extreme conditions
● Custom design capabilities to meet unique client needs and operational challenges
Typical engineered products include FOSV, IBOP, Kelly Valves, stabilizers, crossover subs, and downhole drilling tools used in onshore and offshore operations.
Engineering Coordination with Manufacturing
Unionlever OFS engineers work directly with factory engineering teams to:
● Review and confirm drawings before production
● Optimize design details for manufacturing feasibility
● Control key dimensions, tolerances, and critical interfaces
● Resolve technical issues during production
This approach ensures that engineering decisions are not theoretical, but directly translated into reliable, manufacturable products.
Customization & Engineering Support
Unionlever OFS provides engineering support beyond standard products, including:
● Custom dimensions and connections
● Material upgrades or alternatives
● Application-specific modifications
● Technical clarification and drawing confirmation
Our engineering involvement enables international clients to source China-manufactured oilfield tools with a level of technical control comparable to established global suppliers.
