Built for Pressure. Proven in the Field.
The United States continues to lead global energy production through tight-oil and shale developments across the Permian, Eagle Ford, and Bakken basins. As wells reach deeper and lateral lengths extend beyond 10,000 ft, maintaining safe, reliable well control becomes a critical engineering challenge. Every choke, valve, and manifold connection must perform flawlessly under high pressure, high temperature (HPHT), and abrasive flow conditions.
Parveen Industries has engineered a new generation of API 16C choke & kill manifolds designed to help U.S. operators achieve maximum uptime with minimal non-productive time (NPT). These systems integrate precision manufacturing, PR2-tested components, and modular skid layouts purpose-built for modern multi-well pad drilling.
1. API 16C + PR2-Tested Assurance
Every Parveen choke & kill manifold is fully compliant with API 16C and API 6A standards. Each assembly undergoes PR2 testing — a demanding sequence of pressure and temperature cycles verifying sealing integrity over thousands of open-close operations.
Pressure boundaries use forged bodies, ring-type joint flanges, and hammer unions machined from NACE MR0175-certified materials for sour-service wells. This combination ensures that the manifold maintains integrity even during extended fracturing or flow-back campaigns.
2. Adjustable and Positive Chokes with Erosion-Resistant Trims
Tight-oil wells often carry high sand loads that erode conventional choke trims. Parveen’s adjustable choke valves and positive chokes feature tungsten-carbide and ceramic-lined beans capable of withstanding abrasive flow streams without loss of control accuracy.
Each choke includes a quick-service bonnet design allowing seat or bean replacement in minutes, reducing downtime between wells. The result: precise flow regulation, longer service intervals, and measurable savings in maintenance cost.
3. Isolation Valves that Guarantee Control
Manifolds are equipped with slab-type gate valves and manual gate valves pressure-tested up to 15,000 psi. All valves are PR2-qualified, meaning they can operate reliably through multiple thermal cycles and high-pressure events.
Incorporating check valves and plug valves into the manifold layout provides redundant isolation pathways, ensuring that pressure can always be safely managed during kick control or formation testing.
4. Modular Skid Design for Quick Rig-Up
Parveen’s unitized well-control skids redefine efficiency on multi-well pads. Compact enough for single-lift transport, each skid integrates choke and kill lines, header blocks, and valves on a single frame.
Connections use API hammer unions and flanged tees & crosses for rapid make-up and pressure testing. Operators report up to 40 % faster rig-up and pressure-test cycles compared to conventional assemblies, translating to measurable reductions in NPT.
5. Material Engineering for Harsh Shale Environments
Parveen’s choke and gate valve trims employ HVOF-applied tungsten-carbide coatings (70 HRC) that resist sand erosion in Delaware and Williston Basin wells. Internal sealing surfaces are nitrided for hardness and corrosion resistance.
For extreme HPHT conditions, high-temperature service gate valves deliver metal-to-metal sealing reliability at temperatures exceeding 400 °F, ensuring safe isolation even during prolonged well stimulation.
6. Field-Proven Layouts that Reduce NPT
Every manifold skid is shipped with hydrostatic test certificates, traceable material documentation, and 3D layout drawings to simplify installation. By optimizing flow geometry and reducing connection count, Parveen’s layouts lower leak potential and speed up pressure testing. Field data from U.S. operators show up to 35 % reduction in downtime compared to legacy manifold systems.
7. Supporting Systems for Complete Well-Control Integration
Parveen’s product portfolio extends beyond manifolds, including blowout preventers, surface safety valves, check-valve unions, and treating irons — enabling seamless integration across the well-control stack. Each product follows the same API-certified, QA/QC-verified manufacturing process trusted by global drilling contractors.
Engineering Confidence Under Pressure
From the Permian to the Bakken, tight-oil drilling has redefined operational intensity. Parveen’s high-performance well-control equipment helps operators meet these challenges with dependable, API-certified engineering.
By combining PR2-tested valves, erosion-resistant chokes, and quick-rig modular designs, Parveen ensures safe, efficient, and consistent performance across America’s most demanding oilfields. Every component is a commitment to precision — because in well control, reliability is not optional.
FAQs
What does API 16C certification guarantee?
It confirms that a choke & kill manifold meets stringent design, material, and testing criteria for HPHT well-control applications defined by the American Petroleum Institute.
How do PR2-tested valves improve uptime?
They are pressure-cycle tested across temperature extremes, ensuring dependable sealing and torque performance throughout long drilling campaigns.
Why are tungsten-carbide trims used in chokes?
They offer superior resistance to sand erosion, maintaining precise pressure control and extending component life.
Can Parveen manifolds handle sour gas service?
Yes. All pressure-containing components are manufactured using NACE MR0175-compliant materials for H₂S environments.
How does modular skid design reduce NPT?
Quick-connect unions and compact framing cut rig-up and test time up to 40 %, minimizing equipment handling and pressure-test delays.
