The oil and gas industry operates in some of the most extreme environments on Earth — from offshore platforms in the North Sea to desert wellheads in the Permian Basin, from Arctic pipelines to tropical refineries. Computing equipment deployed in these environments must withstand conditions that would destroy standard hardware in hours.
Environmental Challenges
Temperature Extremes
- Desert wellheads: Ambient temperatures exceeding 55°C, with solar loading pushing enclosure temperatures above 70°C
- Arctic operations: -40°C to -50°C during winter months
- Rapid cycling: Equipment moved between heated control rooms and outdoor conditions
Explosive Atmospheres
Oil and gas facilities contain zones where flammable gases, vapors, or dust may be present. Computing equipment in these zones must be:
- ATEX certified (EU) or Class I Division 1/2 (North America)
- Intrinsically safe or installed in purged/pressurized enclosures
- Designed to prevent any spark or hot surface that could ignite the atmosphere
Corrosion
- Salt spray in offshore and coastal environments
- H2S (hydrogen sulfide) exposure in sour gas operations
- Chemical exposure in refinery environments
Vibration and Shock
- Drilling rig vibration from rotary equipment
- Compressor station vibration from reciprocating and turbine compressors
- Transportation shock from helicopter and supply boat transit to offshore platforms
Remote Location
Many oil and gas computing deployments are in locations with:
- No network connectivity (satellite only)
- Limited power (solar, generator, or battery)
- Infrequent maintenance visits (weeks to months between site access)
Key Applications
SCADA and Process Control
Monitoring and controlling wellheads, pipelines, compressor stations, and processing equipment. Requirements: high reliability, serial communication for RTUs, multiple display outputs.
Safety Instrumented Systems (SIS)
Emergency shutdown (ESD) and fire & gas (F&G) systems that must operate independently of the main control system. Requirements: SIL-rated, redundant, extreme reliability.
Pipeline Monitoring
SCADA systems monitoring flow, pressure, temperature, and pig tracking across hundreds of miles. Requirements: remote operation, cellular/satellite communication, low power.
Video Surveillance
Security and safety monitoring of remote facilities. Requirements: multiple video inputs, NVR storage, low maintenance.
