Engineering durability and precision for the Gulf’s most demanding oil and gas fields.
Saudi Arabia’s hydrocarbon fields such as Ghawar, Safaniya, and Khurais present some of the most challenging production environments in the world — with high temperatures, elevated hydrogen sulfide (H₂S) levels, and high-pressure conditions. Meeting these demands requires API 6A-certified wellhead systems that can operate flawlessly in HPHT and sour service conditions.
Parveen Industries provides an end-to-end portfolio of wellhead and Christmas tree assemblies, casing heads and spools, gate valves, and adaptors etc. designed for long-term reliability in the GCC’s toughest drilling conditions.
API 6A Integrity for HPHT Operations
All Parveen wellhead components are manufactured to API 6A (20th Edition) specifications, ensuring conformity in design, materials, and performance testing. The casing head and spool systems are built with forged alloy steel, subjected to non-destructive testing and hydrostatic verification at 1.5× working pressure. Each sealing interface — whether elastomeric or metal-to-metal — is qualified for repeated make-up and pressure cycling under HPHT conditions.
Built for Sour Gas: NACE MR0175 and CRA Metallurgy
Wells in Ghawar and Abqaiq frequently contain corrosive H2S and CO2 gases, making corrosion resistance vital. Parveen employs Corrosion Resistant Alloys (CRA) such as Inconel, and duplex stainless steels in its sealing assemblies, gate valve trims, and tubing hangers. All wetted components comply with NACE MR0175 / ISO 15156 for sour service environments, ensuring long-term structural and sealing integrity.
Modular Stacks that Reduce Installation Time
Traditional wellhead stacks can take hours of assembly and testing on site. Parveen’s modular pre-assembled wellhead stacks streamline installation with pre-aligned casing heads, spools, and hangers that can be installed as a single unit. This design not only reduces rig time but also minimizes human error, improving both safety and operational efficiency.
Integrated gate valves and flanged tees enable flexible surface layout options for both onshore and offshore rigs. Field operators in the GCC have reported up to 30% faster installation cycles when deploying Parveen’s modular systems.
Christmas Tree Assemblies for Safe and Reliable Flow Control
Parveen’s X-Mas tree assemblies provide precise flow management and are available in single, dual, and multi-completion configurations. Designed for working pressures up to 15,000 psi, they incorporate metal-to-metal sealing gates and grease injection ports for leak-free performance. Each assembly undergoes full hydrostatic, gas, and PR2 testing prior to dispatch, ensuring readiness for field deployment.
End-to-End Wellhead Solutions for GCC Operators
Parveen’s wellhead systems integrate seamlessly with surface-controlled subsurface safety valves and choke & kill manifolds to provide complete well-control assurance from the surface to the reservoir. Designed to meet GCC national oil company specifications, Parveen’s API-certified systems deliver both safety and operational continuity across drilling and production phases.
Proven Reliability in Every Pressure Zone
With five decades of engineering excellence and Parveen Industries has become a trusted partner for well-control and pressure-system solutions across the Middle East. Every wellhead system is built on precision, durability, and field-tested reliability — engineered to thrive where temperature, pressure, and corrosion converge.
FAQs – Wellhead Systems for Saudi Arabia
What is the purpose of a wellhead system?
A wellhead system provides structural support and pressure control for the casing strings and tubing in an oil or gas well, forming the interface between downhole and surface equipment.
What makes Parveen’s wellheads suitable for HPHT wells?
All systems are API 6A-certified and tested for high-pressure, high-temperature cycles using premium alloy steels and CRA sealing materials.
How do modular wellhead stacks save rig time?
They allow installation as a single pre-assembled unit, reducing alignment work and testing time, leading to faster well completion.
Are Parveen wellhead systems compatible with Saudi Aramco standards?
Yes. Parveen’s API and NACE-compliant designs meet or exceed GCC operator and Saudi Aramco specifications for HPHT and sour gas wells.
What maintenance practices extend wellhead life?
Routine inspection of sealing surfaces, pressure testing, and lubrication through grease injection fittings ensure long-term reliability in corrosive conditions.
