Rapid Yield Crude Oil Assay

Rapid Yield crude oil quality testing provides near real-time monitoring of changes in crude oil quality. From the well-head to the refinery.

The continuous monitoring of crude oil quality provides timely and valuable information which is useful to operational and market producers, traders, refiners, and other participants in the hydrocarbon supply-chain.

Intertek's Rapid Yield Crude Oil Assay program provides prompt, near real-time, monitoring of crude oil quality changes, from production through the supply-chain to the refinery.

The Rapid Yield program is supported by Intertek's global service and testing network. Sampling and shipping crude oil samples in 30 ml VOA sealed bottles is fast and easy using IATA and UN 1267 compliant shipping kits. Crude oil samples are shipped via air and usually cost less than other more conventional shipments of crude oil samples.

The Intertek Rapid Yield sample shipment program allows the preservation of lighter molecules in the crude, by preventing them from evaporating during opening of the container in the lab. Once in the laboratory, the crude oil sample is drawn from the container directly through the septum, ensuring a more accurate quantification of volatile hydrocarbons in the crude.

Rapid Yield incorporates a combination of Gas Chromatography (GC) techniques which utilize a software package specifically developed for testing the quality monitoring of crude oil. The first GC technique using the ASTM D6730 method allows for the evaluation of all individual molecules in the crude up to nonane, or carbon number 9.

Rapid Yield provides an accurate monitoring of reforming and alkylation precursors, and allows easy identification of contamination of the crude with any foreign material.

The second GC technique using the ASTM D7169 method is the simulated distillation of crude oil, which allows accurate yield prediction of the crude through 700 C° or carbon number 100. 

The yield curve produced by merging of these GC methods gives an accurate picture of the yield structure of the crude oil, which can be monitored for quality changes of any type. The Rapid Yield program shows a strong agreement with physical distillation test methods, along with detailed molecular data, enabliing easy identification of variations in crude oil quality.
