Oil and Gas Equipment Cost Database: Inside Kpex Module A
Kpex Module A contains cost models for process plant equipment families — compressors, vessels, heat exchangers, pumps and more. We explain the data structure, coverage and how to use it.
What Is Module A?
Module A of the Kpex platform contains cost models for individual process plant equipment items — the fundamental building blocks of a bottom-up CAPEX estimate. It covers the major equipment families found in oil and gas production, refining, petrochemical and chemical process facilities.
Equipment Families Covered
- Rotating Equipment (A.1.1) — Compressors, fans, blowers, pumps, turbines and drivers across all major types and technology variants
- Static Equipment (A.1.2) — Pressure vessels, process columns, reactors and storage tanks across material classes and pressure ratings
- Heat Transfer Equipment (A.1.3) — Shell and tube heat exchangers, air coolers, fired heaters and specialty heat transfer equipment
- Material Handling Equipment (A.1.4) — Conveyors, elevators, feeders and associated handling systems
- Miscellaneous Equipment (A.1.5) — Agitators, mixers, dryers, filters and other specialty equipment families
How the Cost Models Work
Each equipment cost model in Module A expresses purchased equipment cost as a function of the primary sizing parameter — capacity (flow, power, heat duty), physical dimension or weight. Models are presented as cost curves with confidence intervals, calibrated against vendor quotes and executed project purchase orders. Costs are expressed in USD at the module reference year, then adjusted to any other date or location using the CAF Cost Adjustment Index (Z.5) and CAF Location Factor Index (Z.4).
