The SGM-200 is utilized for various production logging (PL) and downhole evaluation applications such as gamma ray/CCL depth correlation, locating leaks, detecting non-performing perforations, locating fluid entry zones, fluid identification, detecting channels, etc.

If precise flow data is required, the Micro-Smart SFM-200 Downhole Memory Flowmeter is run in combination. The SP-2000 Downhole Memory Gauge (pressure) can also be utilized for fluid identification and pressure monitoring. A slickline depth recorder monitors and stores time/depth data.

Accurate, reliable, QUALITY DATA leads to WELLBORE SOLUTIONS. The

SGM-200 uses a custom scintillation gamma detector with the sensitivity required for formation depth correlation. Fluid capacitance and borehole temperature sensors are mounted in a full-open window for optimal exposure to wellbore fluids.

The capacitance sensor’s large count range for air to water (3000 cts) and the sensitive, high resolution, platinum RTD temperature sensor provide quality data necessary for the evaluation of wellbore fluid dynamics. Large memory capacity is adequate for long duration logging projects.

Some advantages of slickline verses electric-line operations are:

• cost savings
  - less equipment and personnel
    required
  - less time required for transport and
    rigging
• safer operation
  - more reliable pressure control with
    less environmental hazard
• improved data quality
  - memory tool data is cleaner,  
    eliminates noise problems
    associated with electric-line
• more reliable data acquisition

- reliable battery and dual EEPROM
  tool memory eliminates potential
  problems with data transmission to
  surface unit via electric-line
  and power failures (surface
  equipment and electric-line shorts)
