Surface Control Equipment
Computer system, custom software for survey control and report generation, power supply, and interface module for sonar probe.
Subsurface Sonar Probe
State of the art electronics, magnetic compass, gyro compass, velocimeter, rotating and tilting mechanism, and acoustic transducer. The transducer can tilt to +/- 90 degrees ensuring complete imaging of the cavern. The acoustic echo data is sampled at 2.8 degrees or 1degree intervals.
3.5 inches Length: 72 inches ( add 36 inches if centralizer used ) Weight: 85 pounds ( add 10 pounds if centralizer used ) Maximum operating temperature: 150 degrees F Maximum operating pressure: 6000 p.s.i. Range accuracy: +/- 0.5% Range: Minimum – 1 ft. Maximum – 900 ft.Gyro accuracy: <.1 deg drift/hr
Sonar Measurements Through Pipe
One pipe: <600 ft. radius Two pipe: <400 ft. radius One pipe and LPG: <200 ft. radius Range accuracy dependent upon the condition of the pipe (e.g. scale, corrosion)
Sonar Measurement in GAS
Natural Gas under pressure (min 1500 p.s.i.) up to 300 ft.
Sonar Measurement in Crude Oil
Up to 425 ft.
