MULTI-WELL COMPUTERIZED CONTROL OF FLUID PUMPING

Title:

MULTI-WELL COMPUTERIZED CONTROL OF FLUID PUMPING

Document Type and Number:

WIPO Patent Application WO1999015756

Kind Code:

A3

Abstract:

A system for controlling one or more borehole pumps (10) includes a computerized controller (120) which, in combination with sensors (20), monitors and controls the activity of the pump, thereby controlling fluid in the borehole. The system is continually in one of three modes: the monitoring mode, the pump mode, and the recovery mode. Within each cycle of modes, the system performs multiple checks on the apparatus involved. The data obtained during the check is stored in appropriate databases as well as checked against predetermined norms. In the event of a malfunction within the apparatus, or other supervised and/or monitored functions, the system can activate a notification system, such as a centralized monitoring facility (102). A pump (10) is disclosed with a fluid sensor (2) to detect the presence of fluid and transmit this presence to the computerized monitoring system (12). A slug sensor (48) notifies the computer (120) of the beginning and end of a predetermined quantity of fluid.
