Staatsolie Pilot Project: Suriname State Oil Company
Objectives:
· To assess and compare Smart Pumper’s performance, quality control, online web-based automation and its economic feasibility with previous well head systems.
· To evaluate, monitor and analyze Smart Pumper’s automation performance including data transfer rates from remote locations to workstations.
 
Background:
Traditionally, Petroleum Engineers (PE) monitor well performance on a monthly basis based on flow tests, pressure tests, service information and other historical data.  Reservoir Engineers (RE) also used pressure data to monitor well behavior, and periodically request a pressure build test so that necessary reservoir calculations and predictions can be undertaken. 
 
Initiation of long term testing of three systems:  
The well shown is 290w05 in the Calcutta Field. The Smart Pumper™ solution turned out to be a low cost automated variable speed lifting option for PCPs that can also provide PEs with FBHP, FBHT, RPM, etc. to their desktop from the remote locations, saving considerable time in the management of the wells that were so equipped. 
 
RE's could also remotely activate a pressure build up test and monitor their pressure surveys in real time at their desktop without dispatching crews to go out and start, record, and then return to restart wells after a test period.  They could also make real-time adjustments to the programmed schedule of build-up and draw-down tests, thereby minimizing associated production loss.
 
Analysis of the results:
1. User Friendly web-based graphical interface accessible to those with proper user definition and password for specific levels of authority; Administrator, Field Manager, PE, RE, Well Pumper (Operator), Electrical, Maintenance.
 
2. Event log, Reports, Manage Well Page, and other aspects were easy to navigate.
 
3. Response time when commanded to change RPM or shut-down averaged 9.23 seconds and was purely based on internet connection speed at our location.
 
4. Email as well as automated SMS can be programmed.  Primary log parameters can be retrieved from the well such as FBHB, FHBT, Volts, Hz, amps, RPM as well as secondary log parameters like torque, theoretical flow and fluid level. 
 
5. For pilot, data flow was from Smart Pumper™ to local cell service provider Digicel, into internet tunnel in Suriname, to server in Houston and back.
 
6. Cost comparison between current installed system and Smart Pumper™: Smart Pumper™ was half the cost.
 
7. With Smart Pumper Automation installed on 290w05, there was a 21% increase in barrels produced compared to the prior 10 months primarily due to maintaining better actual real time fluid level control.
 
8. Fluid level control via the variable frequency drive (VFD) linked to the Smart Pumper’s proportional integral derivative (PID) controller is quite smooth.  The point from which there is a perturbation until this is corrected to the target level programmed matches; i.e., if you stipulate 90 days, it takes 90 days to target (once the pump is sized correctly).
 
9. The data retrieved from the online dashboard of well 290W05 is repeatable within the 6 sigma (standard deviation) band.
 
10. During the 12 month pilot, there were no maintenance issues that hampered the functionality of the Smart Pumper Automation.  A 100% uptime was registered.
 
Conclusion:
The Smart Pumper Automation Package is user friendly and, once installed, immediately transferred the data to the online server with an average 9.23 second response time per signal command or data retrieval. 
 
With the system installed, developers realized a reduction in travel time and cost of field operators to the wells, which allowed them to increase the completion of other meaningful tasks by focusing on other field duties.  Control of the fluid level to target was accomplished as programmed into the Smart Pumper™.  The product also eliminated all unnecessary operator, PE and RE intervention with regard to attempting well optimization. 
 
The Smart Pumper is much cheaper than Data Loggers that only logs data. The installed sensors and cables provided have worked effectively for the past 12 months.
