Central America ; Costa Rica
Project Type: Research

DESCRIPTION: The project will analyze logging-while drilling (LWD) and wireline logging azimuthal measurements to determine best-fit orientation of borehole breakouts. The final paper will describe the implications of the results for the tectonics of the Costa Rica convergent margin.
