ABSTRACT:
A well treatment fluid composition that comprises a carrier fluid and an amphoteric surfactant, and optionally a viscosifying agent and proppant, is well suited for use in fracturing coal beds to stimulate methane production. The composition preferably is a foam that comprises a gas such as nitrogen or air. Preferably, the surfactant has the formulain-line-formulae description="In-line Formulae" end="lead"?R—NH2—(CH2)n—C(O)OXin-line-formulae description="In-line Formulae" end="tail"?wherein R is a saturated or unsaturated alkyl group having from 6-20 carbon atoms, n is from 2-6, and X is hydrogen or a salt forming cation.
