P.K. Services International Inc. and Nexen Inc. invite you, or a suitable member of your organization, to attend an information session on a cost-effective, proven approach to increase oil recovery and reduce H2S in production based on a new oil-releasing/sulfide-destroying biological system called Bio-competitive Exclusion (BCX) Technology.

Background
The award-winning BCX technology was developed by Geo-Microbial Technologies and The LATA Group, and is supplied in Canada by P.K. Services International Inc. This residual oil-releasing/sulfide-destroying biological system is proven to be effective and economical in the field.

The BCX process functions in-situ at the molecular and pore level throughout the aqueous phase of the reservoir by stimulating targeted indigenous, beneficial anaerobic microorganisms. These powerful microbes continuously produce chemical and physical oil-releasing agents including gases, solvents and surfactants. These well known oil-releasing mechanisms have a dramatic effect on oil trapped by capillary and other interfacial forces. The bio-products act at the interfacies of oil, water, rock and pore throat, releasing and mobilizing the trapped oil for production. This modification of the reservoir microflora has a concurrent effect of repressing SRB activity and respiration of sulfate, resulting in a significant reduction or total elimination of H2S/iron sulfide production. The BCX process is proven in medium-to-high gravity oil recovery and H2S reduction and prevention.

The recognition that it is possible to direct and manipulate certain microbial species within the reservoir for beneficial purposes has enabled The LATA Group to develop and introduce various oil recovery technologies, products, and applications, including recently developed heavy oil recovery techniques (patents pending).

Purpose
To introduce the BCX process to the Canadian market and to identify heavy oil field trial partners.

Benefits 
• Improved oil recovery
• Sweetens gas
• Reduces corrosion and cleans wells 
• Creates safer work environment for personnel
