The Middle Magdalena Basin is an actively producing region in Colombia, which in recent years has been chosen for development by means of water and steam flooding. However, complex stratigraphy has challenged the development of a detailed reservoir static model. The Tenerife 3C-3D experimental survey was conducted in 2009 as an integrated application (from acquisition design to interpretation) of multicomponent technology to differentiate lithology (sand and clay) in a Colombian field. The Tenerife 3C-3D survey was twice as expensive as conventional surveys in the same region, so a requirement was to evaluate its added value. The acquisition design resulted in a 22.3 km2 survey with a trace density of 480,000 traces/km2. After careful processing, the PP and PS data were jointly inverted for elastic properties. Even though density is the best discriminator for clay volume in this area, it was not possible to obtain a reliable estimate. Density log data were unavailable for all Tenerife wells, and shear sonic was available for only one well. However, it was possible to derive sand and shale probability volumes using the output elastic attributes from PP and PS joint inversion.
