Four different questions behind one job title

Filter What it means Examples
Project environment Where the technical activity is undertaken Offshore, onshore drilling, LNG facility, engineering office, workshop, marine supply base
Employment relationship Legal or commercial contract with the worker Permanent employment, fixed-term employee, contractor/consultant, internship
Project stage How the project progresses Exploration, development drilling, construction, commissioning, production, turnaround, decommissioning
Work schedule When and how workers attend the worksite Regular office hours, shifts, field travel, rotations or shutdown campaigns

Offshore roles

Offshore work may involve fixed production platforms, mobile drilling units, support vessels or specialist intervention jobs. Some assignments are rotational with remote living arrangements and emergency readiness. An offshore location does not automatically indicate a particular salary, duty cycle, training certificate or vessel-crew qualification.

Onshore roles

Onshore work can include production fields, drilling rigs, gas processing, LNG facilities, refinery-linked equipment maintenance, bases, terminals and project-construction worksites. The physical demands and industrial hazards depend on the asset and job.

Project-based and fixed-term contracts

Project roles may be hired for construction, start-up, engineering campaigns, turnarounds or decommissioning. A fixed-term contract may cover a specific calendar term, while a contractor arrangement can be based on a service agreement. These concepts should not be collapsed into one label; different countries may regulate each relationship differently.

Shutdown and turnaround work

Plant maintenance campaigns can create concentrated work over a defined period. Relevant teams may include mechanical, electrical, instrument, scaffolding, inspection, lifting, planning, quality and HSE staff. Fatigue management, permits and equipment isolation remain essential. Do not assume a temporary project always qualifies as an internship or full-time permanent role.

What to read in a project job offer

  1. Legal hiring entity and whether it is direct employment or contracting.
  2. Worksite and mobilization point, including country and possible offshore transfers.
  3. Project phase, expected contract dates and uncertainty about extensions.
  4. Schedule and actual rotation (if any), travel, accommodation and insurance arrangements.
  5. Applicable medical checks, task training and mandatory permits.
  6. Payment basis, overtime terms, taxes and return transport provisions, as applicable.

How we plan to filter verified jobs

OilfieldPeople will let readers combine country and regional location, project environment, job family, employer category, employment type and work schedule. A missing job match will lead to related learning guides without masquerading as an active vacancy.
