..., and 1007 which were drilled during ODP Leg 166 as well as boreholes Clino and Unda, which were drilled in 1990. In comparison with siliciclastics, relatively little information is available on the acoustic behavior of carbonates. Several studies have been made (e.g., Raymer et al. 1980 ; Rafavich...

... Sr) have been made on fluids obtained from two deep boreholes (Unda and Clino) drilled on the Great Bahama Bank. As a result of the fact that these holes were drilled through cemented Limestones, it was not possible to squeeze sediments to obtain interstitial pore waters, and instead the fluids were...

... the deviations instead of the neutron-porosity log. See the text for explanations and interpretations. Unda is characterized in the upper part down to 100 m depth by a mainly negative velocity-deviation trend, which is likely the result of a strong karstic overprint resulting in a cavernous borehole...
