The process of mapping and analysing an underground reservoir's size, rock properties, and fluid content. Subcontractors use this data to understand scope for drilling, completions, and intervention work. It directly influences crew requirements, equipment specs, and contract duration.
Reservoir Characterization
Related Terms
Extended-Reach Completions
IndustryCompletion work performed on wells drilled at extreme horizontal distances from the surface location, sometimes exceeding 3,000 metres laterally. Subcontractors face longer tool-run times, specialised equipment requirements, and increased logistics complexity. Mobilisation planning and crew scheduling must account for extended job durations compared to conventional completions.
Thermal Hotspot
IndustryAn area of abnormally high surface temperature detected during infrared inspection of electrical, mechanical, or process equipment. Hotspots often signal failing components, loose connections, or insulation breakdown requiring urgent repair. Subcontractors must document and report findings promptly to avoid liability and costly unplanned shutdowns.
Subsea Tieback
IndustryA pipeline or flow line system that connects a new offshore wellhead or satellite field back to an existing production facility or platform, allowing operators to develop remote reserves without building standalone infrastructure. For subcontractors, tiebacks often involve specialised subsea installation, inspection, and maintenance scopes that require certified divers, ROV crews, or subsea engineering support.
PCP (Progressive Cavity Pump)
IndustryA rotary pump used in oil and gas production to lift heavy or viscous fluids from wellbores. Subcontractors are frequently hired for PCP installation, maintenance, and rod-string servicing. Familiarity with drive heads, stators, and rotors is essential for field technicians working these jobs.
Well Program
IndustryA technical document outlining the planned scope, procedures, and specifications for drilling or completing a well. Subcontractors use it to understand required services, equipment, and sequencing before mobilising. It directly affects how you scope work and price your bid.
Oil Rigs
IndustryStructures used to drill for oil and gas, either onshore or offshore. For subcontractors, they are primary worksites where specialised services like maintenance, inspection, and equipment supply are contracted. Mobilisation requirements, safety certifications, and site access protocols vary significantly between rig types.
