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
CIP (Capital Improvement Program)
IndustryA planned cycle of major infrastructure upgrades or expansions at a facility, often releasing large volumes of subcontract work. For field service companies, CIPs signal sustained project pipelines worth pursuing long-term agreements for. Monitoring client CIP schedules helps subcontractors forecast workload and mobilise crews strategically.
EVA (Extreme Value Analysis)
IndustryA statistical method used to predict the likelihood of rare but severe events, such as equipment failures or extreme weather. Field service contractors use EVA to assess project risk and plan contingency resources. It helps justify standby equipment costs and mobilisation buffers in contract negotiations.
VLCC (Very Large Crude Carrier)
IndustryA massive oil tanker capable of carrying up to two million barrels of crude. Subcontractors providing marine maintenance, inspection, or coating services may be mobilised to service VLCCs at port or in dry dock. These vessels require specialised certifications and safety compliance for anyone working aboard.
Letter of Interest
IndustryA formal document a subcontractor submits to a prime contractor or operator to express intent to bid on upcoming work. It is not a binding commitment, but helps secure a spot in the tender process. Common in pre-qualification stages for large oilfield or construction scopes.
Pipeline Flushing
IndustryA pre-commissioning process where fluids are pumped through a pipeline to remove debris, scale, and contaminants before operations begin. Subcontractors are often scoped for this work as a standalone mobilisation. Ensure your quote covers fluid disposal, equipment, and standby time separately.
Turnkey Contract
IndustryA fixed-price agreement where the subcontractor delivers a fully completed scope of work for a set sum. You absorb all cost overruns, so accurate estimating and tight cost control are critical. Profit or loss depends entirely on how well you manage execution against your original bid.
