Mitigating Reservoir Souring through Biological Monitoring

Professionals in the upstream oil and gas production industry have been aware of sulfate-reducing prokaryotes (SRP) in oilfield fluids since the early 1900’s however, it wasn’t until the 1990’s that their significant impact on reservoir souring was fully recognized. SRP reduce inorganic sulfur-containing compounds like sulfate and produce hydrogen sulfide (H2S) which is a colorless… Read More

Most Wanted Microbes – Methanogens

  From the editor: This is the thirteenth post in an ongoing series profiling microorganisms of particular significance in water and wastewater systems. In this series we will cover microorganisms of many types including some that are beneficial, inhibitory and pathogenic.  Methanogens are a group of microbes that produce methane gas through the breakdown of… Read More

Cocktail Party Examples – Microbiologically Induced Corrosion

Their global client base includes users in the food and biocorrosion space. As we discussed in a previous blog post, Microbiologically Influenced Corrosion (MIC)… Read More

Most Wanted Microbes – Iron Reducing Bacteria (IRB)

  While sulfate reducing bacteria (SRB) are widely known as a major cause of MIC in carbon steel, other bacteria with different physiological properties have been identified as potential contributors in the corrosion process as well.  Iron reducing bacteria (IRB), for example, are heterotrophic facultative anaerobes which reduce ferric ions to ferrous ions under anaerobic… Read More

Most Wanted Microbes – Sulfate Reducing Prokaryotes

  From the editor: This is the third post in an ongoing series profiling microorganisms of particular significance in water and wastewater systems. In this series we will cover microorganisms of many types including some that are beneficial, inhibitory and pathogenic.  Sulfate Reducing Prokaryotes (SRP) are a class of microorganisms that reduce inorganic sulfur-containing compounds… Read More

Study finds industrial water needs to be used more efficiently

  An interesting report came out recently from financial analysis firm, Barclays. Along with the Columbia Water Center (CWC), the company was looking at the future of industrial water usage in the United States. Specifically, how large-scale water users can impact potential water scarcity through improved water efficiency practices. The report concluded that $1 trillion… Read More

Bah! H.U.M. Bug!

  We know that phrase all too well, as the one Ebenezer Scrooge shouts out in the famous book  A Christmas Carol.   To a fuel manager, however, it means something entirely different but equally scary. We’re talking about Hydrocarbon Utilizing Microorganisms, commonly known as H.U.M. Bugs. There are at least 27 types of microbes that… Read More

The Economic Case for Microbiological Control in Fuels

  Individual retail gasoline outlets can potentially increase annual revenues by as much as $30,000 per year through a more pro-active microbiological testing program using LuminUltra’s Quench-Gone Organic Modified (QGO-M) test kit. Uncontrolled microbiological growth in fuel systems is one of the main contributors to filter plugging (Passman, 2001). If the microbiological population in Underground… Read More
