C/O tools are being applied in an increasingly wider variety of borehole configurations. One such is a barefoot completion. This paper will discuss laboratory and computer modeling of the C/O response for Halliburton?s C/O tool (RMTE centered or eccentered in uncased wells spanning the range of 4 ½-in.. to 12 ¼-in.. Borehole fluids of fresh, 100kppm saltwater, and oil were used. Test formations included sandstone, dolostone, and limestone with freshwater, oil, and 100 kppm saltwater saturating the pore space. Generally, the sensitivity of the C/O response to formations containing oil was higher as compared with the C/O response for cased wells of the same borehole size. However, borehole size and fluid effects were also somewhat greater. A technique for translating these measurements to standard conditions (i.e., a 7-in.. cased hole with a 10-in.. borehole is also described. Translation to standard conditions has the advantage that it allows use of a standard interpretation package for those who process such data.
