MIC is a problem in the oil and gas industry due to seawater injection. Biocides lead to resistance by microbes over time. In this work, D-amino acids were used to enhance the tetrakis (hydroxymethyl) phosphonium sulfate (THPS) biocide against a tough field biofilm consortium.

Biocides are used to control problematic microorganisms in the oil and gas industry. High doses of biocides cause environmental and operational problems. Therefore, using biocide enhancers to make biocides more effective is highly desirable. 2,2-dibromo-3-nitrilopropionamide (DBNPA) is a popular biocide because it is broad-spectrum, effective, kills microorganisms immediately upon addition, and it degrades rapidly. D-amino acids are natural chemicals that have been used in lab tests to enhance biocides to treat biofilms. In this work, D-tyrosine was used to enhance DBNPA against Desulfovibrio vulgaris biofilm on C1018 carbon steel. After 7 days of incubation, the weight loss of coupons without treatment chemicals in culture medium was found to be 3.1 ± 0.1 mg/cm2. With a treatment of 150 ppm (w/w) DBNPA, the weight loss was reduced to 1.9 ± 0.1 mg/cm2 accompanied by a 1-log reduction in the sessile cell count. The combination of 150 ppm DBNPA + 1 ppm D-tyrosine achieved an extra 3-log reduction in sessile cell counts and an additional 30% reduction in weight loss compared with 150 ppm treatment of only DBNPA. The combination also led to a smaller maximum pit depth. Linear polarization resistance (LPR), potentiodynamic polarization and electrochemical impedance spectrometry (EIS) tests corroborated the enhancement effects.
A top-of-line corrosion (TLC) model integrated into a CO2/H2S corrosion prediction model. The TLC model determines the top of the line corrosion rate of carbon steel based on water chemistry and film-wise condensation rate. The effect of various glycols, such as Monoethylene Glycol, Diethylene glycol and Triethylene Glycol, are included.
Traditionally, oil recovery operations are subdivided into primary, secondary and tertiary stages. EOR is commonly classified as tertiary recovery, where gases, liquid chemicals and thermal energy can be used to enhance the displacement of reservoir fluids. Different sources divide EOR into two to five categories, one particular method, polymer flooding, is based on increasing the fluid viscosity by adding a polymer to the injected water. Polymer EOR is a mobility-control process using a polymer-augmented waterflood, typically a solution of partially hydrolyzed polyacrylamide (HPAM) or polysaccharides, which is injected to displace oil towards production wells.
A novel software framework Predict-RT incorporating intelligent predictive analytics linked to process historian has been created to provide refinery / process operators the ability to see corrosion damage in real time. Built on decades of intense experimental corrosion data and predictive model development this framework offers first-of-its-kind insights to proactively manage unit operations optimize throughput management and derive enhanced safety and reliability through real-time linkages to process data. The system also enables easy implementation of industry-best practices through support for API RP584 (Integrity Operating Windows) and API RP970 (Corrosion Control Documents).This paper describes the overall predictive framework and provides recent industry case studies / practical applications related to refinery crude unit monitoring to highlight the potential of intelligent software-based predictions to drive efficient linkage between process data and degradation. The systems ability to correlate corrosion rates to process upsets while trackingcumulative wall loss at critical locations and drive proactive inspection management is also highlighted.Key words: Intelligent systems predictive analytics crude unit corrosion mechanical integrity corrosion prediction software
Due to their excellent performance properties, epoxy coatings are commonly used over metal and concrete substrates in applications where corrosion protection and chemical/solvent resistance are key requirements. One weakness of these epoxy coatings is their poor UV durability. Epoxy coatings typically have poor gloss and color retention as well as poor resistance to chalking on exterior exposure.
Cathodic protection (CP) is a well-established technique that effectively prevents corrosion of metals by adjusting the equilibrium potential of metallic structures in an electronegative direction. As the applied current increases, it reduces the anodic dissolution rate, thus leading to a decrease in the corrosion rate. The effectiveness of CP can be confirmed by measuring the protection potential values along the structures, ensuring the uniformity of the applied current, and observing the resultant potential distribution in the field.
The oil and gas industry have constantly been striving to improve efficiency and reduce costs. Advanced materials and their enhancement were one of the strategies to achieving the aforementioned goals. These materials are specifically designed to withstand harsh corrosive conditions and sustain production capability over an extended period of time. There’s a number of ways to enhance material integrity of sweet gas wells, including using CRAs, chemical treatment, monitoring wellbore environment and properly maintaining wellbore components.
This research paper describes the various predicaments and issues to enhance the effectiveness of environmentally responsible food grade paint, which helps in maximizing safety and reducing the risk of corrosion. The presentation of this report will consider the characteristics of food grade paint as well as enumerates the companies that produce food grade paint.
A Saudi Aramco facility continues to serve a vital rule in the processing and export of crude oil. This facility is one of the few facilities worldwide that is considered to be fully sufficient with different processes within its boundaries. While processing hydrocarbon throughout the day, this facility also processes utilities to serve the nearby community as well as its own oper ation. The raw water that feeds the utility process arrives from a nearby fields through the 24” supply lines. These lines provide n. the subject RO plant within the utility process with the sufficient amount of water to sustain the huge magnitude of operation.
