Sometime More Is Just More: THPS Biocide Laboratory Kill Study on Wildtype Sulfate Reducing Bacteria.

Product Number: 51323-18858-SG

Tetrakis(hydroxymethyl)-phosphonium Sulfate (THPS) is a very common active ingredient in oil and gas biocides. While product labels provide broad guidelines application dosing the lowest effective dose of THPS is difficult to determine. Site water chemistry and bacteria biology variability will affect the dose need to achieve the desired level of bacteria population control. For these reasons biocide dose response studies are commonly conducted on solutions containing bacteria to determine the effect of treatments before application.

Synergistic Effect of Magnetite-Enriched Rust Layer and Sulfate Reducing Bacteria on Pipeline Steel Corrosion in Oilfield Produced Water

Research shows that microorganisms play a significant role in corrosion of buried steel pipes. Partially hydrolyzed polyacrylamide (HPAM), a polymer commonly used to enhance oil recovery (EOR) from reservoirs, has been found to benefit microorganisms as a nutrient source, resulting in severe microbial corrosion of steel in the vicinity. Herein, microbial corrosion behavior of carbon steel was examined under active Fe oxide and inert sand deposits in oilfield water containing HPAM and sulfate-reducing bacteria (SRB). The electrochemical results show that corrosion rate of the steel under the Fe oxide deposit was generally higher than that under the sand deposit. The steel under the Fe oxide deposit suffered severe pitting assault with wider and deeper pits of about 32.65 µm. In comparison, corrosion severity decreased in the sand-deposited sample (having a maximum pit depth of 11.22 µm). The results demonstrate a synergistic effect between SRB activities and Fe oxide deposits to exacerbate steel corrosion in the oilfield water containing HPAM gel.

Utilizing Corrosion Damage Morphology As An Indicator Of Microbiologically Influenced Corrosion (MIC) In Oilfield Waters

Product Number: 51322-17687-SG

Author: Moavin Islam

Publication Date: 2022

$20.00

Microbiologically Influenced Corrosion (MIC) is a major concern in process industries, particularly in the Oil and Gas sector. It is estimated that 25-30% of corrosion related failures in pipelines and industrial equipment can be attributed to MIC. The cost of metallic corrosion has been estimated to range between 2-3% of the gross domestic product (GDP) in developed countries and MIC certainly accounts for a significant fraction of the total cost of corrosion amounting to billions of dollars due to unexpected shutdowns, equipment replacement, mitigation strategies, etc.
