Specialist SV Sensors

OSIL/AML have supplied a set of specialist SV sensors, calibrated to 2000 m/s, as part of the instrumentation package for use in water-filled cavity survey and well logging applications. The vertical sonar instrument was designed around a standard 4" bore to enable easy access to the majority of situations. The sonar is capable of surveying subterranean caverns, sub-sea caverns and wells.

As some of these environments may have parameters outside the normal range for seawater (such as high temperatures, high pressure and very high salinity/brine conditions), the requirement for accurate sound velocity readings becomes increasingly more important.

With this in mind, OSIL/AML have developed a specialist SV sensor, capable of operating over the range of 0 - 2000m/s at elevated temperatures and pressures. The units have already been successfully deployed in both well logging and brine cavity monitoring applications.
