Abstract
A downhole tool for acoustically imaging a subterranean formation having a transmitter and receiver and which includes an acoustic isolator between the transmitter and receiver. The acoustic isolator includes attenuation elements with rounded ends and that are connected in series by compression fittings. The compression fittings include sleeves that threadingly engage lock nuts and compressively engage the rounded ends. The contact interfaces between the compression fittings extend along a curved path thereby limiting acoustic transmission along the series of attenuation elements.
