Engineered for Extremes — Parveen’s Wellhead Systems for Ghawar and Beyond

Parveen API 6A wellhead system designed with CRA metallurgy for sour gas operations in Saudi Arabia’s Ghawar field. TL;DR

  • Saudi Arabia’s upstream sector operates in ultra-high temperature (UHT), high H₂S and CO₂ environments, demanding the toughest wellhead systems.
  • Parveen delivers API 6A-compliant assemblies with CRA sealing, metal-to-metal barriers, and premium metallurgy for sour service and thermal cycling.
  • Robust designs proven in global HPHT plays make Parveen a reliable partner for Saudi Aramco projects and beyond.

Why “extremes” define Saudi oilfields

From the Ghawar field, the world’s largest onshore reservoir, to offshore sour gas developments, Saudi Arabia presents some of the most challenging well environments globally:

  • Reservoir temperatures >175°C
  • High H₂S and CO₂ partial pressures requiring corrosion-resistant alloys (CRA)
  • Deep HPHT completions that demand metal-to-metal sealing integrity
  • Long life cycle wells where reliability across decades is non-negotiable

In these extremes, wellheads are not just pressure barriers — they’re the frontline of safety and production continuity.

Parveen’s wellhead system solutions

1. CRA & material integrity

Parveen engineers API 6A wellhead equipment using CRA (Nickel-based alloys, Duplex, Inconel cladding) to mitigate sulfide stress cracking and CO₂-induced corrosion. Products such as the Tubing Head, Casing Head, and Tubing Head Spool are available in CRA options to withstand sour environments.

2. Metal-to-metal sealing

Unlike elastomer-based designs that degrade under UHT, Parveen provides metal-to-metal sealing technologies across Gate Valves, Choke Valves, and Wellhead Crosses & Tees. This ensures gas-tight barriers through decades of thermal cycling.

3. Pressure & flow control for HPHT

Saudi HPHT operations demand precision choke and kill systems:

4. Accessories & unions for reliability

High-integrity wellhead assembly with metal-to-metal sealing technology for ultra-high temperature Saudi oilfield environments. Reliability for Ghawar and beyond

Saudi fields require wellheads to operate for decades with minimal downtime. Parveen’s designs are tested for:

  • Thermal cycling endurance (UHT to ambient transitions)
  • H₂S/CO₂ sour service certification
  • API 6A PSL 3G and PR2 performance levels for severe service

By combining global field-proven metallurgy with localized customization, Parveen ensures compatibility with Saudi Aramco’s stringent specs.

Commercial benefits for Saudi operators

  • Reduced lifecycle cost through longer service life in sour gas wells
  • Improved uptime via reliable barriers and automation-ready interfaces
  • Safety assurance in HPHT completions and blowout prevention programs
  • Proven export partner with decades of global upstream experience

FAQs — Wellheads for Saudi HPHT & sour fields

Q1. What makes Parveen wellheads suitable for sour gas fields in KSA?
Our systems use CRA metallurgy and metal-to-metal seals that resist H₂S cracking and CO₂ corrosion over decades of service.
