The ADL Stable Foam method has an impeccable safety record of no incidences of down hole explosions and/or surface fires. Air does not enter the formation due to the low-pressure gradients and viscosity exhibited by stable foam.
The gaseous phase within the foam is encapsulated within the bubble. Formation gas is absorbed into the bubble. ADL has established in the field that hydrogen sulfide to 10,000 ppm can be neutralized by adding H2S scavenger to the Stable Foam. The gas is then trapped in the foam and is slowly released once it reaches the surface containment vessel. Nitrogen or non-gasses can be used for greater safety if volatile fluids such as condensate or flammable solvents are present.
Stable Foam encapsulates air, eliminating one of the ignition sources needed for a potential explosion. With the frequency of unwanted well detonations and associated liabilities, Stable Foam’s ability to eliminate the condition for combustibility within a well cannot be over emphasized.
The lack of an atmosphere eliminates flammability and combustibility satisfying Directive 033 and reducing the liabilities of your well sites. Stable Foam does not leave harmful environmentally toxic residuals, satisfying the growing demands of host communities, concerned about aquifer contamination and other environmental affects.
ADL has treated over 750 wells with productivity improved without safety or environmental incidents. This is an extraordinary record we are proud of, obtained not by luck, but directly influenced by trained personnel, coupled with detailed well assessments, and engineered work plans. Everything from foam make up to equipment placement is considered. We set up our work space neatly and efficiently.
After testing several surfactants for use with ADL’s patent foam generation system, a unique chemical composition was created by ICTC for exclusive use by ADL. The lifting capability has increased exponentially since the original chemical design, and is again undergoing another growth cycle with the help of Tim Leshchyshyn, P.Eng, a fracturing and chemical expert, who is currently setting up lab testing and chemical controls required for case studies, with the assistance of such renowned institutions as the University of Alberta.
