SAS®
Surface Acquisition System
- Well head pressure and temperature measurement, display and recording
- Well head pressure and temperature real time acquisition by transmission to a PC
- Automatic well recognition through well identifiers for routine multiwell surveys
- High accuracy and resolution of pressure and temperature measurements
- Automatic compensation of environment temperature changes
- Data can be merged with down hole data for complete analysis
- Operated & read by any IBM compatible PC even portable
 The SAS is a measurement system that measures, displays and records well head pressure and temperature. Connected to any IBM-PC compatible computer it allows real time data acquisition. It measures well head pressure through a liner that connects to its 1/4” NPT port. A temperature probe acquires the well head temperature. If used in connection with well identifiers, the SAS recognizes the well being surveyed and records it with the measured data. Recorded data are read by the Metro Win software that allows complete analysis and merge with other down hole or surface data.
