| A complex technology for thermal recovery from bitumen wells has been developed and tested in the field. It provides natural bitumen recovery enhancement and reservoir neutralization of the corrosive acidic components which result from the bottomhole treatment. The neutralization is accomplished with alkaline solutions. This technology allows to lower the bottomhole temperature for the purpose of casing string protection. |
