Indonesia’s Offshore Reality: Multi-Zone, Multi-Well, Tight Decks

Offshore Indonesia mixes brownfield tie-backs with new multi-zone wells on compact platforms and jack-ups. Operators must balance high well counts with limited topside real estate, demanding wellhead packages that are:

  • Modular: configurable for single/dual completions and multi-zone flow paths without redesigning the stack.
  • Lightweight & compact: to reduce structural load, footprint and hook-up time.
  • Instrumentation-ready: clean routing for pressure/temperature taps and choke actuation.
  • API 6A/16C aligned: barrier integrity and compatibility with your BOP and test program.

Parveen’s Modular Wellhead Building Blocks

Start with a robust API 6A core and add modules as needed—no clutter, no surprises:

How the Modular Approach Saves Time & Weight

  1. Pre-engineered stacks: standardized spool heights and flange adapters reduce on-rig machining and rework.
  2. Instrument-ready from day one: add transmitters via studded crosses/tees and route signals through a unitized data header—fewer hot-work hours, cleaner cable runs.
  3. Compact valve layouts: adopt pneumatic gate valves and adjustable chokes that fit within tight envelopes while maintaining service access.
  4. Unionized connections where appropriate: use hammer unions/quick unions to accelerate make-break on test loops and temporary tie-ins.

Designing for Multi-Zone Flow Paths

Multi-zone completions need clear separation and controllability. Parveen’s architecture supports:

Example Layouts & Testing

Use Parveen’s Typical Single/Dual Completion Wellhead & X-Mas Tree Assemblies as a starting point. For commissioning and well testing, reference the Layout for Testing Gas/Condensate/Oil Wells and include Blind/Test Flanges to streamline pressure verification.

Can we phase upgrades as the field matures?

Yes. Start with a core API 6A stack—tubing head, casing head, spool—and add modules: adjustable chokes, pneumatic gates, data headers, and additional tees for sensors.

How do you reduce topside load without sacrificing integrity?

By standardizing spool heights, compact valve bodies, and optimized flange groups (weld-neck, flanged tees), we minimize weight while retaining API 6A barrier integrity.

What makes your assemblies instrumentation-friendly?

Provisioned tappings via studded crosses/tees plus centralized routing through a unitized data header for cleaner cabling and fewer leak paths.

Can Parveen support multi-zone well test operations?

Yes. Combine the Choke & Kill Manifold with the Hydraulic Drilling Choke and follow the recommended test layout to manage backpressure and measurement points.

What intervention equipment do you recommend offshore Indonesia?

Grease control heads, stuffing boxes/alt, lubricator & risers, and CT stripper packers ensure safe live-well work with limited deck space.

Are your systems compatible with our existing BOP and test iron?

Yes. Parveen wellheads and C&K manifolds align with API practices and tie-in via hammer/quick unions, test flanges, and standard flange groups.

Parveen helps engineering teams configure the right modules for multi-zone offshore wells—cutting installation hours and keeping deck loads lean while preserving API 6A integrity.
