Permanent well monitoring system SPSK-SIAM

Successful field development due to obtaining prompt and reliable data and loss minimization while well testing

General concepts

the permanent well monitoring system consists of surface and downhole equipment and is designed to obtain accurate data about downhole pressure and temperature on a real-time basis;
the base of SPSK-SIAM is one or several high accuracy quartz gauges or strain pressure gauges installed in the borehole and transmitting pressure and temperature measurement data over separate cable (tech-cable or logging cable) into the surface control module on a real-time basis;
the surface control module is designed to store, display, transfer survey data and to set SPSK;

the selection of optimal inflow performance;
well potential assessment and reservoir state;
the possibility to lower several high accuracy sensors via the tech-cable or the logging cable;
the surface control module is equipped with a reserve supply system (when the power is cut, the system continues working for 7 days);
the surface control module is equipped with a heating system and can be explosion protected*;
The permanent well monitoring system can be equipped with self-contained power supply on the basis of solar panels, wind-powered generators, or battery-powered*;
the data transfer system can consist of a satellite communication modem and / or GSM Modem with the possibility to set the intervals of measurement data transfer;
the controller provides receiving data from submersible sensors over a separable cable, as well as visualization of received data;
Data storage in a standard SD card;
Measurement data can be copied by means of direct connection of a computer to interface block via USB port;
