Downhole Electronic Shut In Tool - PRELIMINARY
SST-1200

Play it Smart!
Don't allow wellbore storage effects to degrade your pressure build-up data.
The new SST-1200 Downhole Electronic Shut-In Tool from Micro-Smart Systems automatically shuts-in your well near the reservoir, removing wellbore storage effect, and minimizes production downtimes.

Our simple switch programmable electronics means no computer is necessary to prepare the tool for a standard shut and open sequence. Simply select the duration of the flow period and duration of the buildup period. It's that easy.

Of course, multiple shut/open sequences, up to 20 sequences, may be programmed into the SST-1200 to allow more elaborate production tests to be performed. Programming is accomplished by using any PC, via serial port, and Micro-Smart's user friendly software.

The SST-1200 incorporates a proprietary seal design to allow the tool to operate and seal properly in a wide variety of downhole conditions. Our innovative flow passages are designed to optimize flow, virtually eliminating the "choke" effect.

Power is supplied by 5 'C' cell or 5 'C-C' cell lithium battery packs. The cells are chosen based on the length of time downhole and the number of shut/open cycles.

The SST-1200 is run below a customer supplied lock mandrel and mechanical equalizer. Attached below, a shock absorber, pressure gauges, and centralizer complete the necessary equipment.

Micro-Smart Systems has a variety of dependable, field proven pressure gauges available to acquire precise build-up data. Your SMART choice for cutting-edge technology and superior customer service is Micro-Smart Systems.
