Control of Reservoir Souring and Corrosion Prevention in Production Systems in Response to Nitrate Injection Cessation

Product Number: 51324-20806-SG

Reservoir souring remains a challenging problem for the oil & gas industry, especially in aging assets where H2S and microorganisms from the reservoir can pose a serious risk to the integrity of producing wells and equipment. Nitrate treatment is commonly used to control SRB activity in the reservoir, but it is not always effective due to poor subsurface definition and increasing volumes required over time. In this study, we evaluated the use of a biocide to replace nitrate injection in reservoir conditions when nitrate is no longer effective to control SRB activity. We used sour, sand-packed reactors to evaluate a biocide formulation applied prior to and after nitrate cessation. Measurements of VFAs, nitrate, sulfide and genomic analysis were used to assess souring and changes in the microbial population. The results indicated that biocide was successful to remediate souring when applied before AND after the nitrate treatments. However, the cumulative amount of generated sulfide was higher when the biocide was applied after nitrate cessation, indicating the need of temporary co-injection of nitrate and biocide to prevent a H2S wave period. Genomic analysis indicated that this formulation specifically targeted the SRB rather than broadly killing the microbial population. Taken together, this study highlights a new strategy to control reservoir souring and potential corrosion issues in producing wells.

Evaluation of A Rapid Solution For SRB Monitoring In Industrial Water System

Product Number: 51322-17554-SG

Publication Date: 2022

$20.00

Uncontrolled growth of microorganisms in the oil field production systems have a major negative impact on the productivity and asset integrity in oil and gas industry. Sulphate-reducing bacteria (SRB) have been found as the most troublesome group of microorganisms among all organisms involved in MIC of carbon steel and other metals used in the oil industry (Abdullah et al 2014). The formation of SRB biofilm on steel surface can affect the kinetics of anodic and cathodic reactions, leading to an acceleration of steel corrosion (Beech and Sunner, 2004: Zuo,2007). In addition to that, SRB contributes to hydrogen sulfide-driven reservoir souring, increased suspended solids, reservoir plugging, etc., in oil field sites.

Failure of 24” Common Crude Piping and Formation of Iron Sulfides Due to the Influence of Sulfate & Iron Reducing Bacteria and Methanogens

Product Number: 51322-17545-SG

Publication Date: 2022

A leak suddenly occurred at the 24-inch common crude piping from the separators heading to the degassing boot inlets and the wet crude tanks in an oil gathering center. The initial observations showed the leak was due to a deep isolated pit and localized corrosion. Additional inspections by manual ultrasonic thickness (UT) and long range ultrasonic thickness (LRUT) measurements for the 24” common crude line showed similar deep isolated pits (up to 70% thickness reduction) scattered across the length of the 1100 meter piping.

Microbiological Profile and Risk Exposures in Topside Production Systems of FPSOs in West Africa

Publication Date: 2022

The incidence and proliferation of microbial population in oil and gas production facilities can have undesirable consequences on upstream, midstream and downstream production systems. Microbes thrive in the anaerobic conditions encountered in these systems and are supported by nutrients and metabolites found in produced water. Although the majority of process and water injection systems are susceptible to microbial fouling, the development of microbial activity is exacerbated by specific conditions such as stagnant fluids or the presence of deposits.¹ Threats of microbiologically influenced corrosion (MIC) and other challenges associated with microorganisms have become valid as more cases are reported. While MIC, biofouling (BF), and reservoir souring are three of the most common problems associated with microbes, many other production issues can be attributable to microbial activity including: employee infections, filter plugging, loss of injectivity, and metal sulfide deposits.²
