Shearwater wins OBN work for Shell-operated Sabah asset — implications for regional seismic activity
Teknologam follows regional seismic survey developments closely, especially where our manufacturing supports offshore campaigns. Shearwater's recent award to survey a Shell-operated field off Sabah signals renewed exploration and appraisal activity and tighter logistics across the supply chain. We see supplier and contractor coordination intensifying as the market shifts toward targeted OBN acquisition in Southeast Asia.
Key Takeaways:
- Shearwater awarded an OBN contract for a Shell-operated field — a tactical return to high-resolution imaging offshore Sabah.
- The contract shows how OBN technology drives clearer subsurface models, aiding fast-track development decisions.
- For Teknologam, this opens supply opportunities and reinforces our regional manufacturing support for OBN campaigns.
Project context and what was announced
Shell has advanced plans for activity in Malaysia’s waters, prompting Shearwater Geoservices to respond with a tailored OBN campaign. Industry reporting confirms the booking as an OBN survey contract for a Shell field off the west coast of Sabah, which signals operator intent to de-risk reservoirs with high-fidelity data. The award reflects growing capital allocation toward appraisal and near-field exploration in the region. For the original industry notice, see the report on the contract award: Shearwater awarded OBN contract for Shell-operated field off the west coast of Sabah — Energy‑Pedia.
Key insight: this procurement indicates operators favor OBN for complex shallow-water imaging where conventional methods often underperform.
Technical scope and survey approach
OBN acquisition offers superior azimuthal coverage and waveform fidelity in structurally complex areas. Shearwater’s survey will likely use node patterns optimized for imaging beneath shallow carbonates and faulted intervals. Data processing will emphasize full‑waveform inversion (FWI) and localized velocity model building to support reservoir characterization.

From our field engineering perspective, tight node deployment schedules and robust node-recovery strategies reduce operational risk and maintain data quality. Anticipated technical priorities include:
- Node layout optimized for multi-azimuth coverage.
- Battery and communications planning for extended deployments.
- Processing workflows that emphasize FWI and multi‑component imaging.
Operational and regional logistics
The announcement that Shell tapped Shearwater for a survey offshore Sabah underscores the need for disciplined logistical coordination. Mobilization must align vessels, supply chains, and port services in Malaysia. Local-content expectations remain central, and contractors often engage regional suppliers for handling, maintenance, and fabrication.
Operational logistics considerations:
- Vessel coordination and scheduling to minimize downtime.
- Local supply chain integration for spares, tooling, and rapid repairs.
- Environmental planning and stakeholder engagement with local authorities and communities.
Market implications and industry ripple effects
A contractor win on a Shell‑operated asset typically attracts complementary service demand. Providers of specialized buoyancy systems, node housings, ROV support, and bespoke handling frames can expect upticks in inquiries. For fabricators like Teknologam, there is clear potential to supply tailored components that meet OBN environmental and handling specifications.
Shearwater’s public positioning around the award highlights confidence in regional demand and positions the company as an active partner across Central & SE Asia / Australasia. That signaling encourages nearby operators to consider similar campaigns, which in turn drives demand for local fabrication, repairs, and rapid prototyping.
What Teknologam sees and how we position ourselves
We view this award as an affirmation of OBN’s business case in Southeast Asia. Teknologam plans to prioritize:
- Rapid prototyping of node enclosures using corrosion‑resistant alloys and marine-grade coatings.
- Localized supply chain readiness to support expedited mobilization and on‑site turnarounds.
- Service partnerships to support node life‑cycle maintenance, repairs, and spare‑parts provisioning.
Our engineering teams can adapt existing designs to meet Shearwater‑style operational profiles, shortening lead times and reducing integration risk. We will also emphasize documentation and testing protocols that align with operator QA/QC expectations for OBN campaigns.
Closing perspective
This contract demonstrates the practical pivot to higher‑resolution offshore imaging in the region. As Shearwater secures an OBN survey contract for a Shell field off Sabah and the market responds, suppliers must align capabilities quickly. Teknologam remains ready to support OBN deployments with specialized components, local manufacturing agility, and service partnerships that de‑risk mobilization and sustainment.
