From 2007 to 2022, Chevron’s Mid-Continent Business Unit (MCBU) in Midland, Texas, experienced several challenges in establishing and implementing an effective internal coating management strategy for the upstream, aboveground storage tanks (ASTs) built to American Petroleum Institution (API) Specification 12F. In this journey, Chevron has addressed and resolved the opportunities shared in this Paper and listed below to enable sustainable and reliable life of coating systems applied to ASTs working in produced water and crude oil service (upstream sector):

• issues around legacy specifications of tanks acquired from other owners
• establishing the right coating systems for tanks internal surfaces
• quality issues with coatings on newly constructed tanks ordered from local manufacturers
• having multiple contracts for AST coatings field repairs
• field hot work repairs of tank floors with a foam base
The solutions that Chevron MCBU has implemented to address the issues above might be used by others to leverage from Chevron’s experience and practices to improve their AST coating management strategies.
