A bstract An analytical solution of refraction problems in anisotropic media is based on the expression for the refraction angle in an uniaxial anisotropic medium with vertical axis and elliptic anisotropy. The theory is applied to a test on the anisotropic behaviour of the sedimentary section in the vicinity of Betun, South Sumatra, employing the results from a refraction profile, a well velocity survey and a radial well survey. It is concluded that, in the Betun area, the anisotropy factor is variable with depth. Its maximum value may be as high as 1.15 in the middle part of the section.
