Abstract
An acoustic method is disclosed for measuring fluid level in producing wells and other inaccessible cavities. The method uses flow induced pressure phenomena to locate the fluid level. Simplified equipment is involved and acoustic velocities can be measured externally from the well. The method applies to known uses for fluid levels such as well productivity, lift equipment design, and reservoir studies.
