The purpose of this paper is threefold. First, we will use a simple synthetic example to demostrate that delay times without information about weathering velocities will not yiel a unique refraction static solution (Archer and Heathcote, 1985). Second, we will ilustrate with a field data example how use a refractor elevation model can improve a refraction static solution. Third, we will show that the benefits of a commonly used technique -so called "residual refraction statics"- can be obtained more appropriartely using a refractor-elevation model. Since the primary concern is model construction and static calculation, we assume that accurate delay times are available for both the synthetic and fiel data examples. p. 253-256 CONGTP Daly, C. 9239 Diggins, C. 9240 Congreso Nacional de Hidrocarburos (1er. : 1989 abr. 17-21 : Mar del Plata) 9207 Diggins, C. 9240 Daly, C. 9239 133265 133265 0 0 0 0 204184 CBAAB CBAAB 068.82-553.28 C62 1 1989 2026-03-04 200005687 0 068.82-553.28 C62 1 1989 200005687 2026-03-04 14:03:05 2026-03-04 CONGTP
