  • Page 5: 2-Principles Of Acoustic Measurements

    Fluid level instruments are designed to include various filters, which can be used to accent signals that correspond to these frequency ranges. The Model M records the signal on the dual channels. One channel is tuned to higher frequencies from the collars while the second channel is tuned to low frequencies from the liquid level.

  • Page 6: Depth Calculation

    The acoustic instruments can be used to measure the distance to any change in cross-sectional area inside pipe or in the annulus. Echometer Company Phone: (940) 767-4334 Model – M Manual 5001 Ditto Lane Page 6 Fax: (940) 723-7507 Wichita Falls, Texas 76302, U.S.A.

  • Page 7: General Description - Model M

    (orreduction in annulus area) is opposite to the response from an enlargement such as a hole in the casing. The Model M uses modern electronics, integrated circuits, chart drive system and a thermal printhead, which result in a very compact and lightweight system.

    The paper is dropped into the cavity so that it unrolls counter-clockwise. After inserting the paper roll, the aluminum cover is replaced. The printed Echometer logo on the paper should face up since only this side of the paper is heat sensitive. The heat sensitive paper supplied by Echometer Company operates over a wide temperature range and is made for the Echometer Chart drive system.

  • Page 12: High Pressure Gas Guns

    The casing pressure and casing pressure buildup during the acoustic test must be measured with an accurate and sensitive pressure gauge or sensor. The Remote Fire Gas Gun supplied with the Echometer Model M is equipped with a quick connect gauge that covers the range 0-200 psig. The user should consider the option of obtaining several gauges covering different pressure ranges.

    Universal Coordinated Time Zone in England. The date and time on the enhanced Model M are set as follows. There are two small holes located in the lower panel to the left of the input connector.
  • Page 14 Remote Fire Gas Gun When both collar and liquid level gain controls are set to the “AUTO” position, the Model M will automatically provide a fire signal to the Remote Fire Gas Gun after the chart drive is turned ON.

  • Page 15: Operation

    The upper record is with the filter setting on upper collars and the lower record shows the response when the filter setting is lower collars. Echometer Company Phone: (940) 767-4334 Model – M Manual 5001 Ditto Lane Page 15 Fax: (940) 723-7507 Wichita Falls, Texas 76302, U.S.A.

  • Page 16: Operation Of The Model M With The Compact Gas Gun

    COMPRESSION (EXPLOSION) MODE Expansion of gas from the Echometer gas gun is used to generate a pressure pulse. The pressure pulse is positive since the gas chamber is charged to a pressure that exceeds the well pressure by at least 100-psi.

  • Page 17: Operation Of The Model M With The Remote Fired Gas Gun

    Verify that the volume chamber pressure is at least 100-psi in excess of the Casing Pressure. Connect the coaxial cable from the microphone to the Input of the Model M. 10. Connect the remote fire cable from the gun to the REMOTE FIRE connector.

  • Page 18: Recommendations For Optimum Performance

    Recommendations for Optimum Performance The Echometer wellhead should be as near as possible to the casing annulus (or the tubing) preferably within 5 feet. Short (5-10 ft) lengths of pipe can mask the desired downhole signals. Longer (20-60 ft) lengths will generate multiple reflections, which are hard to distinguish from collar reflections.

  • Page 19: Automatic Gain Setting (Ags) Mode Characteristics

    Automatic Gain Setting (AGS) Mode Characteristics The Echometer Model M uses a microprocessor, which is programmed to evaluate the signal level before the shot and set the amplifier gain as necessary to optimize the quality of the recording. The AGS mode on either or both channels is activated by selecting the AUTO position before the chart drive is turned ON.

  • Page 20: Interpretation

    When the wave passes from the narrow liner to the larger casing a portion of the wave is converted to a rarefaction pulse, which then travels down to the liquid level and then to the surface where it is recorded.

  • Page 21: Problem Wells

    In extreme cases it may be necessary to clean the tubing and casing to remove the foreign material. Echometer Company Phone: (940) 767-4334 Model – M Manual 5001 Ditto Lane Page 21 Fax: (940) 723-7507 Wichita Falls, Texas 76302, U.S.A.

  • Page 22: Battery And External Power Information

    12-volt battery. A sealed, rechargeable, lead cell, 2.5 amp/hour internal battery is used in the Echometer Model M instrument. The battery is similar to a 12 volt sealed automobile battery. The battery charger provided with the unit permits charging the battery from an AC power outlet.

  • Page 23: Important Notes And Instructions For Rechargeable Batteries

    Important Notes and Instructions for Rechargeable Batteries The battery is rated at 2.5 Amp-Hour. The Model M current drain with the chart drive on is 1 Amp. Thus the battery operating ON-time is approximately 2.5 hours and the unit would use about five rolls of paper.

  • Page 24: Testing/Troubleshooting

    8 - Testing/Troubleshooting The Echometer Model - M has an internal test circuit, which is used to verify that the electronics and the acoustic cable are operating correctly. The test circuit is activated automatically when the power is turned ON. A system test and battery voltage is displayed on the strip chart.

  • Page 25: Maintenance

    9 - Maintenance The Echometer Model –M instrument should be kept clean. The battery should be kept charged as described by the instructions in Section 7. Do not subject the unit to shock loads. Using the Compact Gas Gun or the Remote Fire Gas Gun in the EXPLOSION mode (the preferred mode of operation) will require minimum maintenance.

  • Page 26: Remote Fire Gas Gun Pressure Rating

    Replace the "O" rings as needed. All other connectors, ports, and the solenoid valve can be serviced without need to remove the volume chamber. Echometer Company Phone: (940) 767-4334 Model – M Manual 5001 Ditto Lane Page 26 Fax: (940) 723-7507 Wichita Falls, Texas 76302, U.S.A.

  • Page 27: Calculation Of Bottomhole Pressures

On units below serial number 5100, the amplifiers and filters are checked each time that the POWER switch is turned ON.

  • Page 37: Microphone Cable Test

    On Model M Recorders having serial numbers above 5100, the microphone cable is tested in conjunction with the microphone test as described on the next page. On Model M Recorders having a serial number below 5100, the microphone cable can be tested using a special TEST circuit and TEST connector on the panel of the instrument. First, the Amplifier and Filter Check should be performed to insure that the electronics, chart drive and printhead are performing properly.
