Abstract: Certain examples described herein are directed to a foaming agent for utilization in drilling that has greater environmental desirability due to the elimination of molecular ammonia and ammonium ion and further, has the added feature of greater economy while maintaining nominal to superior functioning in the capacity of lifting and performing at characteristic operating temperature. In some configurations, the compositions may desirably omit toxic or flammable substances to include lighter alcohols, and or environmentally persistent components. Further, various embodiments can achieve an improved level of foam stability.
