Adapt Independent Compact Wellhead
11-in wellhead for 2- and 3-string installations
Faster installation with lower HSE impact in unconventional shale plays.
Adapt nested multistage compact wellhead
13 5/8-in wellhead for 3- and 4-string installations
Overview
Improve operating efficiency onshore and offshore
By bringing new flexibility and capabilities to wellhead installation, the globally available Adapt™ nested multistage compact wellhead (Adapt NST wellhead) accommodates multiple casing configurations for quickly adapting to changes in operating conditions, saves significant rig time to cut costs and related CO2 emissions, and improves operational HSE.
The compact design enables efficiently landing multiple casing strings within one wellhead, reducing operating time and cost compared with traditional wellheads. Changes in operating conditions can be responded to rapidly, with the nested profile supporting three- and four-string installations.
Applications
- Unconventional shale plays and conventional applications
- Onshore and offshore locations
- Operations requiring surface casing rotation
- Suitable for smaller cellars, supporting requirements for confined spaces
Benefits
Industry's fastest installation
Rig time savings of up to 45%, or more
Lower HSE risks
Lower CO2 emissions (due to faster installation), smaller footprint, fewer leak paths, reduced exposure to cellar hazards with fewer BOP makeup and breakout connections
Reduced inventory
Components interchangeable across all Adapt compact wellhead systems
Features
- Engineered for batch drilling, pad operations, and reduced-size cellars
- Incorporates industry-leading rotating capabilities for all mandrel hangers with standardized threading and torque capacities up to 50,000 lbf.ft [67,791 N.m]
- Features landing mandrel assembly with metal-to-metal seal that can be run through a diverter and BOP stack
- Accommodates severe well conditions with premium elastomer sealing technology
- Offers optional mechanical position indicator for lower casing hanger landing assurance
- Complies with API Spec 6A and ISO 10423
- Measures approximately 30% shorter than a compact multibowl nested-diverter snap-ring wellhead system
- Uses a single API Spec 6A gasket for 5,000- and 10,000-psi applications
- Offers availability of emergency kits for all strings
