Yegua Trend of Southern Texas


The Yegua II report is designed to assist exploration and production geologists in their understanding of factors that control hydrocarbon distribution in the Yegua formation of the study area. Portions of eleven counties were examined.

More than 2,300 well logs have been correlated to define the up-dip sandstone geometries and hydrocarbon trapping mechanisms.

The report documents the role of depositional systems in trapping hydrocarbons and develops predictive exploration models. These models, combined with net sand maps, make it possible to define fairways in the down-dip trend that have a higher probability for encountering significant sandstone reservoir facies.

This study covers 7,500 square miles in Texas, within which 2,322 wells were correlated, and represents several man-years of geologic research.
