Replacement or modernisation of sensors, transmitters, and control devices on existing facilities. For subcontractors, this work is often scoped as short-duration projects requiring certified instrumentation technicians. Tight commissioning deadlines and client-supplied materials are common on these jobs.

BPD (Barrels Per Day)
IndustryA measure of a well's or facility's daily oil output. Higher BPD typically means greater activity levels, more crews on site, and increased service demand. Subcontractors often see scope and call-out frequency tied directly to a client's BPD targets.
Single-Source Contractor
IndustryA company hired to deliver an entire scope of work, rather than splitting it among multiple subcontractors. For field service subs, this means one firm holds the prime contract and manages all trades underneath. Winning a single-source role improves cash flow and reduces competition, but increases liability exposure.
Steam Circulation
IndustryA process where steam is pumped through wellbore tubing to heat and mobilise heavy oil or bitumen. Subcontractors are often engaged for equipment operation, line connections, and monitoring during circulation cycles. Scope can expand quickly, so confirm change-order terms before mobilising.
MRP (Materials Requirements Planning)
IndustryA scheduling system that calculates what materials are needed, in what quantities, and when. Subcontractors use it to avoid shortages or excess stock on job sites. It ties material orders directly to project timelines and scopes of work.
Kelly Bar
IndustryA heavy, telescoping steel rod that transmits rotary torque from a drill rig to the auger or cutting tool. Subcontractors operating foundation or piling rigs must inspect kelly bars regularly for wear and cracking. Damage affects drilling performance and can cause costly downtime on tight project schedules.
Self-Build
IndustryA project where the owner acts as their own general contractor, hiring subcontractors directly rather than through a prime contractor. For field service companies, this often means faster access to work but requires closer coordination with the owner. Payment terms and scope changes are negotiated directly, so clear contracts are essential.
