Overview - SRO / Memory PLT 

The Production Logging System developed by Spartek Systems is available in either 1 3/8" or 1" diameter. The system utilizes an industry standard RS485 instrument bus to maximize flexibility, and provide easy integration of new measurements. Today, the tool string can be configured to include any combination of the available sensors:
• Accelerometer
• Gamma Ray
• Casing Collar Locator
• Gradiomanometer		 • Dual Pressure Sensors
• Fluid Capacitance
• Fast Response Temperature
• Fullbore Flowmeter
• Caged Flowmeter

Both memory and SRO data acquisition modes are supported. In SRO mode, high speed digital wireline telemetry technology is utilized to transmit data in real time to the PC based surface acquisition system. Alternatively, in memory mode, the sensor data is stored on non-volatile flash memory until it is downloaded at surface using the SparWorks software. This flexibility allows the instruments to be used with electric line, slickline or other conveyance methods to achieve both practical and cost effective operations.
