STC Geostar

Echo-dynamometer
GEOSTAR-111

The system is designed to measure liquid level and casing pressure in oil&gas wells and register a surface dynamometer card of the down-hole pumping unit operation.
Echo-dynamometer GEOSTAR-111 is designed:
– to acquire liquid level and casing pressure in oil wells;
– to register surface dynamometer card of down-hole pumping unit operation;
– to control valves operation;
– to estimate well rate, pumping unit efficiency and BHP data.

System allows to analyze the pump card and to recognize the pump failures and predict the possible faults.

Used by oil production, research and development (R&D) and well logging departments in the oil and gas production companies.

Software EDWin
Software EDWin is designed for processing of dynamometer, echo level meter, pressure, power measurements received from GEOSTAR-111/112 device (echo/dynamometer system).

Software can perform the following operations:
1. Transfer registered data from GEOSTAR-111/112 device to computer.
2. Prepare echo/dynamometer/power cards (view/modify the parameters).
3. Print the large variety of reports such as graphic, table, complex, and statistic ones. The powerful report designer helps to create and modify reports.
4. Export to RTF (Office Word), XLS (Office Excel), JPG image, to the transport format (BND2, EDW), DYN-format and to the customer database (on demand).
