... Biocide Stability and Efficacy in Soured Oilfield Environments Rishi Raj Trivedi, Olivia Stenzel, Seth Sheridan, Marcelo Filgueira The Dow Chemical Company 400 Arcola Rd Collegeville, PA 19426 USA ABSTRACT One of the most problematic and costly microbial issues of the oil and gas industry...

... ABSTRACT Accurate bacteria population monitoring is an important tool in oil and gas production to mitigate microbiologically influenced corrosion (MIC), prevent reservoir souring and optimize biocide treatment strategies. Serum serial dilution testing (SSDT) is a flawed yet widely accepted...

... ABSTRACT Biocides play a critical role in the exploitation of low permeability oil and gas formations via hydraulic fracturing by protecting the integrity of fracturing fluids and preventing the souring of the wells. Traditionally, biocide selection for a well is determined though a limited...

... material loss due to corrosion and fouling of steel surfaces is a daunting challenge for the oil and gas industries. The use of protective polymeric coatings containing active biocides is an interesting approach to address this problem. The development of active anticorrosion/antifouling coatings via...

... ABSTRACT Microbial Influenced Corrosion (MIC) is difficult to control. Therefore, biocides are often added as a preventive measure to exterminate microbial activity and thereby also mitigate MIC. Biocides have the disadvantage that they have to be added continuously and can be hazardous...

... ABSTRACT Hydraulic fracturing, used in unconventional shale gas and oil extraction, uses large amounts of water which needs to be treated with biocides to prevent microbial degradation of the fracturing fluids and subsequent microbial contamination of the reservoir. A growing requirement...

... ABSTRACT Seawater injection is regularly used for pressure maintenance in oilfields during secondary oil recovery. Typically oxygen is removed from the seawater via a process of mechanical deaeration and oxygen scavenger is added to remove final traces. An oxidizing biocide...

... ABSTRACT The use of oxidizers in the oil and gas industry has been increasing in recent years. Peracetic acid, in particular, has been gaining acceptance as a very cost effective and superior biocide for water treatment applications. Though primarily used as biocides; oxidizers, in general...

... was determined to be microbially influenced corrosion. To control the microbial contamination in the system, an initial planktonic kill study was performed to select the best possible biocides to provide immediate microbial mitigation to the field. Upon implementation, resulting field data indicated effective...

... Abstract Biocorrosion or microbiologically influenced corrosion (MIC) is a major problem in many industries, especially the oil and gas industry. Biofilms are the culprits of MIC. In this work, D-amino acids were used to enhance two biocides, namely alkyldimethylbenzylammonium chloride (ADBAC...

In this study, we hypothesized that the addition of appropriate enzymes or cocktails of enzymes may be able to significantly enhance the effectiveness...
