ABSTRACT:
An apparatus (10) is disclosed for permitting continuous calculations of the depth of the fluid level (12) within a well bore (14) during a test interval. A sonic event is generated in the well bore, and the reflected sonic signals from down hole tubing collars and the fluid surface are sensed and recorded. By knowing the depth of the tubing collars, the fluid depth and speed of sound in the oerlying gas can be computed. Subsequently, the apparatus (10) generates sonic events and records the travel time for the sound to reflect off the fluid surface and return. Measurements of the actual fluid depth and sonic velocity are made at regular intervals, and interpolated between actual measurements to allow the variation in fluid level to be calculated from the measurements of travel time.
