Field connectivity constraints
Sites with intermittent or no connectivity, where any application that assumes a network simply does not get used.
Asset-intensive operations, connected properly
Oil & Gas
Maintenance workflow, operational data and field application work for energy operations where assets are remote, downtime is costly and safety documentation is not optional.
Energy operations run on assets that are expensive, distributed and sometimes hard to reach. The technology problems follow from that: maintenance work managed in systems that field teams cannot reach from site, operational data trapped in historians that reporting cannot reach, and safety documentation that lives in a binder.
The useful work is usually connective — getting maintenance workflow onto devices that work offline, integrating operational technology data with business systems without compromising the OT boundary, and making inspection and compliance evidence a by-product of doing the job.
What we see
Recurring problems in oil & gas
These are the patterns that come up repeatedly. Not all of them apply to you — but if two or three do, the conversation is usually worth having.
OT/IT data separation
Operational data in historians and control systems that business reporting needs, without weakening the security boundary that keeps control systems safe.
Reactive maintenance
Maintenance driven by failure and fixed schedules rather than by condition, because the data to do better exists but is not assembled.
Inspection and compliance evidence
Safety and regulatory documentation captured on paper or in photos on a phone, then re-entered later, if at all.
Contractor and workforce coordination
Permits, certifications and work authorisation tracked across systems that do not talk to each other.
How we help
Where our services apply
Each of these maps to one or more of our service lines.
Offline-first field applications
Mobile applications that hold full function without connectivity and sync deterministically when a connection returns, with conflict handling designed rather than hoped for.
Services involved
Maintenance and inspection workflow
Work order, permit and inspection workflow with structured evidence capture, so compliance documentation is produced as work happens.
Services involved
Operational data integration
Historian and sensor data brought into the analytics platform across a governed boundary, preserving OT segregation.
Services involved
Condition-based maintenance analytics
Anomaly detection and failure prediction on equipment telemetry, surfaced into the maintenance workflow rather than into a separate dashboard.
Services involved
Support for remote operations
Managed application services with extended-hours cover appropriate to operations that do not stop at five.
Services involved

Constraints we design around
Raised at the start of an engagement rather than discovered during an audit.

FAQ
Questions we get asked
Can you build applications that work with no connectivity?
Yes, and it is a design decision that has to be made at the start. Offline-first means local storage, deterministic sync, explicit conflict resolution and a UI that tells the user what state their data is in. Retrofitting it onto an online-first app is close to a rewrite.
How do you approach OT security boundaries?
Conservatively. Data moves outward across a controlled boundary — typically a one-way or brokered path into the IT environment — and we do not put write paths into control systems as part of analytics work. Any integration design goes through your OT security team before build.
Let's talk about what you're trying to build.
A short conversation is usually enough to tell whether we're the right fit. If we're not, we'll say so and point you somewhere better.
