GREETING Chevron–Richard Parrish

In this fourth edition of the Caribbean Basins, Tectonics, and Hydrocarbons (“CBTH”) Newsletter, we provide an update on our completed activities from ExxonMobil– May 2006 and offer an overview of our activities in the Jaime Buitrago, coming months. For those of you who are CBTH spon- Bolaji Famakinwa, sors, we hope over the past four months your group Ron Johnson, Randy Perkey, Robyn Schapiro has become comfortable using the CBTH web-based GIS database and website and that this resource is Newfield–Hank Woods benefiting your exploration efforts. Please let us know if you have suggestions or questions for use of the database.
