OSTI ID:6592619
A borehole imaging apparatus is described comprising: a housing movable within a borehole; at least one acoustic transducer supported in the housing for transducing acoustic energy in such a borehole; and an acoustic fluid in at least a portion of the housing for acoustically coupling the transducer to fluid in the borehole, the acoustic fluid having a low kinematic viscosity substantially less than 50 cSt at 4/sup 0/C, and having an acoustic impedance which minimizes loss of the acoustic energy passing through the housing.
