In this presentation, I describe some of the underlying theory of a method for numerical integrating over a two dimensional curved surface. This is a natural extension of extrapolation (or Romberg integration) for planar squares or triangles. There is no need for an explicit form for the Jacobian. The method may be used when the surface is defined implicitly. However, the integrand function must be regular, and the boundaries of the domain of integration must admit a linear parameterization.
