Oil field pipeline corrosion in addition to seawater injection line
Expanding the use of streamlined DNA extraction techniques to novel environmental microbiology samples
Samples were scraped from the inner surface of oil field pipelines. Two samples, designated "A" and "B", originated from water reinjection lines. They contained substantial quantities of crude oil, corrosion products such as iron sulfides, and extrapolymeric substances (EPS) from "biofilm."   As for the second experiment samples were scraped from the inner surface of seawater injection line. The sample designated "C".  It did not contain crude oil but did contain lesser quantities of corrosion products and EPS.
Three samples were scraped from inner surface of oil field pipelines.  Additionally, three samples were scraped from inner surface seawater injection line
