Tertiary clastic sequences within the Veracruz Basin of Mexico have been prolific hydrocarbon producers for many decades. However, during the last few years, production has declined. Several fields have recently been restudied to evaluate behind-pipe, deepening potential, and new exploration opportunities in the area. This paper focuses on a multidisciplinary integrated reservoir characterization study of Novillero field situated in the Veracruz Basin.

Novillero field, discovered in 1966, has produced about 59 BCF of gas from calcareous turbidites and mudstone-rich debris flows. Reprocessing of 2D seismic in 1996-97, land the generation of synthetic seismograms, permitted the integration of seismic and sequence stratigraphy, AVO analysis, biostratigraphy, well and core data, petrophysical analysis, and production data that resulted in a complete reservoir model based on all available data. This study led to the identification of several opportunities in the field area.

Working on a common integrated LandmarkTM platform, geological, geophysical, petrophysical, and engineering data were integrated. This integration significantly reduced turn-around time and risk. Single-well recompletion of behind-pipe potential in previously untested horizons doubled total field production and led to renewed interest and development of older fields in the Veracruz Basin.
