Strainer Nipple Data Tool
The Strainer Nipple Data Tool (SNDT) is a new design of downhole memory gauge that attaches to the bottom of an oil well pump, or is landed in a cased hole on a collar stop or other accessory. It records up to three years of highly accurate pressure and temperature data, with enough detail to show the shape of the individual pump strokes. Unlike traditional gauge surveys or surface pressure surveys, the SNDT is so reliable and easy to run, it can be operated by the oil company.
While the SNDT is down hole and recording continuously, a variety of pressure transient testing can be initiated by simply shutting in the well or offsetting wells.
Applications
Complete producing bottom-hole pressure histories
Pressure build-up data for regulatory requirement
Pressure response for secondary recovery schemes
Pressure data for interference or communication testing
Pressure data for single- or multi-rate testing
Data to evaluate for skin damage
