On the use of bleach soaks to control bacteria-mediated formation souring
Journal of Petroleum Science and Engineering, 1993Abstract This a case study of a field test undertaken to establish whether the suppression of H2S-producing bacteria near the water injector wellbore could be used to control progressive reservoir souring. Three produced water injectors were soaked with 16 m3 of bleach for 20 h.

The Controlled Freeze Zone Technology for the Commercialization of Sour Gas Resources
IPTC 2014: International Petroleum Technology Conference, 2014Abstract Controlled Freeze Zone™ is an efficient single-step cryogenic distillation process for the removal of carbon dioxide, hydrogen sulfide and other impurities from natural gas. Rather than avoiding the freezing of CO2 at cryogenic temperatures, the solidification is allowed to take place, albeit in a very ...

Control of Sour Rot Using Chemical and Canopy Management Techniques
American Journal of Enology and Viticulture, 2018Sour rot is a disease complex characterized by rotting of the grape berry plus internal development of acetic acid, and it is typically associated with an abundance of fruit flies (Drosophila). Uncertainty regarding disease etiology and epidemiology has limited the development of reliable management practices for sour rot, but it is now known that ...

Corrosion and Hydrate Control in Wet Sour Gas Transmission Systems
SPE Asia Pacific Oil and Gas Conference and Exhibition, 2008Abstract Generally, the most economical material for construction in oil and gas pipeline systems is carbon steel. Besides the safety and environmental issues, downtime caused by corrosion related failures and hydrate-induced blockages in pipelines can be costly to the operator.

Simulation of Bacterial Souring Control in an Alberta Heavy-Oil Reservoir
Canadian International Petroleum Conference, 2009Abstract This paper presents the development of a simulation model describing the bacterial-induced souring of an Alberta heavy-oil producing field and its remediation via injection of nitrate. An area of the field with extensive bacterial activity was selected for the simulation study.

Implementation of Nitrate Treatment for Reservoir Souring Control: Complexities and Pitfalls
SPE International Conference & Workshop on Oilfield Corrosion, 2012Abstract The activity of sulfate-reducing bacteria (SRB) has long been a major concern in oilfield water systems and petroleum reservoirs because these microorganisms are one of the main causative agents of microbial-influenced corrosion (MIC) as well as reservoir souring. Calcium nitrate and sodium nitrate treatments have
