The WellSonic Well Monitor/Controller Package
The Monitor/Controller is illustrated above in one of it's many possible configurations. As the name implies, the basic function of this advanced technology is to 'Monitor' a well and report the fluid level, and other important data, to the operator for solid decision making about operation of the well. The controller function may be activated to act on the information and automatically adjust the proper pumping speed or cycle for maximum well performance. Many additional pressure, temperature and weight reporting functions may be added to the basic fluid level and pressure readings.
Automatic Timed Well Surveys:
Internal timers may be set to automatically take a sounding and process the information at any regular time interval between 1 minute and 1 week. If an unsuccessful, or out of range, sounding is detected, the unit immediately makes additional soundings for verification and comparison. The basic unit may also be timed to take fluid and pressure build-up surveys during a time when the well is shut in for such tests. These times may be at regular intervals, or at a predetermined frequency curve, usually beginning with soundings close to each other at first, and then further and further apart as the test progresses. This information is retained in a standard format which can be easily transferred to any good well analysis program.
Internal Memory:
The basic unit surveys the well automatically, usually once per day, and stores in memory every aspect of the sounding and criteria used to make the survey. One hundred of these surveys are kept in internal memory for download. They also remain in a backup memory for security, after the primary files are downloaded to another medium. The complete sounding is always preserved as raw data on which any number of analysis may be performed without distortion of the original data.
Real Time Analysis and Results:
The survey information is usually gathered each night for assembly on a morning report to the operator. The operator selects the normal ranges preferred for each reading. Some out of range readings are transmitted immediately, if the operator deems them vital to avoidance of damage to equipment or the environment. Low fluid level on an ESP or a high rod temperature on a rod pump, are examples of information which can prevent substantial expense when transmitted as soon as they move out of the preset range, and before they become critical.
Events may be sequenced for a determination as to whether an out of range reading is critical and reported immediately, or simply reported and highlighted in red on the morning report. A slightly out of range flow temperature or amperage reading may trigger an automatic fluid level determination, and this result may instantly notify the operator of low fluid long before any other indicators would normally shut down the pump or notify the operator. If the fluid level is found to be at a safe level, the event may not be reported as urgent, and may then be reported on the normal morning report.
Acoustical Anomaly Analysis™:
This system grows out of the inventor's 37 years as an independent producer. When visiting a producing well, usually a rod pump jack, he would listen and lay his hands on several areas of the operating unit. Any little tap or grind out of the ordinary was pursued to the source. The worker's knowledge that he regularly did this was far more effective than any lubrication schedule sheet, and was a reliable early indication of any developing problems. Holding on to the operating polish rod told him the downhole story long before modern instruments. As he developed this instrument system, the same sounds and vibrations associated with potential problems were very apparent. As riding the beam of an operating unit today would be frowned upon by a long list of public agencies, this old-timer technology has been applied through electronic sensors and sophisticated computer programs with great success.
Remote Communication Links:
Beyond the immediate reporting of a potentially dangerous or expensive condition, a remote communication link to the Monitor/Controller may serve many functions. A sounding may be made and all information read at any time by remote command, from any authorized computer, if any one of the several communication links are employed. The internal program can be reviewed, and updates downloaded to adjust for varying well conditions or range and performance preferences of the operator. The well may be shut in, and a fluid and pressure build-up test completed, from the operator's desktop.
