A Case Study On Microbiologically Influenced Corrosion In Oil Producing Well Flowlines

Product Number: 51322-17924-SG
Author: Amer Jarragh, Sandip Kuthe, Sharad Londhe, Akhil Jaithlya, Abeer Rashed, Nadine El-Kaouri
Publication Date: 2022
$20.00

Oil field operating company’s (1) flowline network in North and West Kuwait (NWK) has over 3000 wells connected through 6” carbon steel pipelines flowing from wellhead to the nearest Gathering Center (GC). Untreated wet crude is transported through the flowlines to GC’s directly or passing through the Remote Headers and Manifold (RHM) to GCs. In RHM, mixing of the wet crude takes place before it is sent to GC’s via transfer lines for further separation.  The flowlines are laid aboveground except at road crossings where they are buried.

Combined Effects of Microbes and Nitrate on SRB Growth Souring and Corrosion

Product Number: 51317--9425-SG
ISBN: 9425 2017 CP
Author: Bei Yin
Publication Date: 2017
$20.00

A stationary testing method and a porous media flow reactor method were used for these studies. The effect of different NRB, including NO2NRB and sulfide-oxidizing NRB (SONRB) on corrosion of carbon steel beads in the presence and absence of nitrate was also investigated using porous media flow reactors.

Effects of Renewable Natural Gas and Hydrogen on Microbially Influenced Corrosion and Souring in Underground Gas Storage

Product Number: 51324-21146-SG
Author: Scott Leleika; Taylor Rambo; Tekle Fida
Publication Date: 2024

A bench scale laboratory experiment was conducted to assess the microbial corrosion and souring effects renewable natural gas (RNG) and natural gas amended with hydrogen have on underground gas storage systems. Steel coupon-containing vials inoculated with produced fluid from an underground storage well were subject to different headspace conditions to simulate underground gas storage. The vials were filled with geologic natural gas, geologic natural gas amended with hydrogen, RNG, and RNG amended with hydrogen. Each condition was subject to molecular (qPCR, and 16S rRNA analysis), liquid chemistry (sulfate and volatile fatty acid), corrosion, and headspace chemistry (major components and trace sulfur) analysis in duplicate at three time points. The results showed that levels of sulfide production, microbial community composition, and coupon mass loss did not differ greatly between the natural gas and RNG conditions. However, the presence of hydrogen did increase the levels of sulfide in both geologic and RNG conditions. There was also evidence of significant biotransformation of hydrogen into an organic acid (formate). This experiment has shown that microbes native to underground storage wells could have an impact on gas quality and corrosion (via hydrogen sulfide production) if hydrogen is introduced.

Iron Source in Sour Gas/Condensate Wells: Reservoir Fluids or Corrosion?

Product Number: 51317--8998-SG
ISBN: 8998 2017 CP
Author: Giulia Verri
Publication Date: 2017

In order to implement an effective iron scale mitigation strategy, operators first need to identify the main source of iron in the system. This work describes a method to predict the “maximum dissolved iron” (MDI) concentration in a reservoir/production system.

Preservative Biocide Selection and Performance in High Pressure High Temperature Bioreactors using a Thermophilic, Hydraulic-Fracturing Relevant Culture

Biocides are used in hydraulic fracturing operations to control the growth of contaminant microorganisms that lead to corrosion, souring, and conductivity loss.1,2 A variety of biocides are utilized and can be classified by mechanism of action, speed of kill, and the length of residual activity.
In general, rapid-acting biocides such as chlorine dioxide (ClO2) and DBNPA (2,2-dibromo-3- nitrilopropionamide) inactivate bacteria quickly but have little to no residual activity. Glutaraldehyde (Glut) reacts more slowly and provides some residual activity, particularly at lower wellbore or reservoir temperatures.

Experimental work has demonstrated that novel combinations of the preservative 1,3-Dimethylol-5,5-dimethylhydantoin and tetrakis hydroxymethyl phosphonium sulfate (THPS).can provide synergistic biocidal performance against commonly found oilfield bacteria.
