INTRODUCTION This field installation manual will detail and explain the operation and installation of the Sercel-GRC FORTRESS ESP Monitoring System, including gauges: ESP-1000 ESP-1500 ESP-1800 ESP-2500 ESP-3500 QESP-2500 QESP-3500 SPS-3000 Surge Suppressor (Protector) Surface Choke and surface readout equipment: SCOUT-2200 SCOUT-3000 SPS-1500 In the Appendix of this manual is a copy of the FORTRESS ESP Monitoring System Field Checklist.
BENCH TESTING AND VERIFICIATION PROCEDURES Note: Bench test and verification procedures are applicable to all Fortress ESP gauges. Tools Required 110V Power Source Either a Sercel-GRC SCOUT-3000 (Surface Readout) o Portable Scouts will include a twisted wire pair with alligator clips Or a SERCEL-GRC SCOUT-2200 Bulkhead Cable Assembly Process Steps for Bench Test and Verification 1. SECURE THE GAUGE to keep the gauge from rolling or moving during testing. 2.
a HOCKEY PUCK Figure 1: Fortress ESP Wiring Configuration b Figure 1A Fortress ESP Wiring Configuration Doc No.
Figure 1B: Fortress ESP Wiring Configuration The end of the 3-phase cable will come out somewhere in the center of the ESP cable spool as shown in Figure 1 above. Follow the steps below to test the gauge through the ESP cable spool once the cable has been connected to the motor. Since the SCOUT is powered by 110 VAC, an external power supply will be needed. Do not set the SCOUT on the Spooling unit as shown on this trailer. ONLY CONDUCT THIS CHECK WHILE THE SPOOL IS NOT MOVING.
INSTALLATION PROCEDURES FOR DOWNHOLE GAUGE Installing the ESP Sensor to the Motor This procedure outlines the best practices that should be taken in the field. The sensor can be mounted to the motor before the motor is shipped to the field. In that case, the procedure will be the same, but probably not done on the back of a flat bed trailer as shown in these pictures. 1.
Figure 3. Gauge stabbed into motor base. 3. Once the sensor has been stabbed as far as shown in Figure 3, place one of the motor base bolts through the bolt hole and into the sensor motor head to make sure that the bolt holes are lined up. DO THIS BEFORE PROCEEDING TO STAB THE SENSOR FULLY ONTO THE MOTOR BASE. 4. Use of the fill and plug valve to fill the gauge with oil from the gauge plug. Most customers do not use the fill and plug valve on the gauge and use the one located on the motor.
Testing the ESP Sensor While Installing Tubing Figure 4. Spooling Unit. Installing the Sensor Discharge Pressure Base Adapter (For ESP& QESP-3500 Gauge Models Only) Discharge Port Connection All Dual Pressure gauges are equipped with a Discharge Pressure Port. The Discharge Pressure Port must be purged with motor oil, vent plugged, and connected to the hydraulic tubing connecting to the pump discharge sub before being deployed.
THIS OPERATION NEEDS TO BE COMPLETED IN ITS ENTIRITY BEFORE THE MLE IS CONNECTED TO THE MOTOR. 1. 2. 3. 4. Remove the fitting and ensure that the NPT threads have been Teflon taped. Install the n fitting back into the base. Remove the compression nut and ferrules. Install compression nut and ferrules onto the capillary tubing ensuring the correct ferrule orientation. 5.
Installing the Resistance Temperature Detector “RTD” (For Non-Factory Installed RTDs, Probe Style) All ESP Gauges monitor Motor Temperature with a Platinum 1K RTD. There are several RTD Motor Temperature Probe options including Probe, Threaded, and customer supplied. Motor Temp probes are mounted inside the gauge assembly and placed against the Motor Windings for maximum temperature transfer and fast response.
Figure 6. Three pieces of shrink tubing on gauge wires. f. Twist one RTD wire and one RTD gauge wire together creating a splice so that it appears as a straight wire and not two wires side by side. At this time solder the two wires together using high temp solder. Do the same step for the other two wires (one from the RTD and the other from the gauge). g. Slide the heat shrink tubing down over each individual soldered bare wire and heat shrink the two pieces of tubing using a hot air gun (heat gun).
Figure 8. Long piece of heat shrink tubing over both wires. Finally, replace the wye point if you have removed it. Attach the Scout-3000 or portable Scout to any of the motor terminals of the wye point or to the gauge wire if not using our wye point. Turn on the Scout and check/record gauge readings. Place the RTD in the position you had determined and reassemble the gauge and motor. Re-check and record readings using the Scout attached to the top of the motor on one motor lead.
Procedure Cut P/N 037-0050-04 off from the communication wire, refer to Appendix Fig. A1. Thread the communication wire through the hole on the terminal. Be sure not to use the RTD wires as all wiring from the choke is white. Fold the excess wire back towards itself making a loop. Refer to Figure 52. Figure 9. WYE Connector Shown with the Communication Wire Prior to Crimping. Any excess wire extending beyond the insulation of the wire should be removed.
Now solder the wire to the terminal with the aid of flux making sure not to leave any sharp edges. Refer to Fig. 11. After soldering, clean the solder with alcohol and slide the clear plastic wire insulator to the solder joint. Refer to Fig. 11. Figure 11. WYE Terminal Shown with the Communication Wire Soldered. Slide one piece of heat shrink tubing down to the hex base of the terminal. Apply heat to shrink the first heat shrink tubing before applying second layer of heat shrink tubing. Refer to Figure 12.
Now slide the second piece of heat shrink tubing down to the base of the threaded pin. This will go over the first heat shrink tubing. Refer to Fig. 13a. Figure 13. WYE Connector Shown with the Second Heat Shrink Tubing. Apply heat to the heat shrink to complete the assembly. Refer to Fig.13b for final assembly. Figure 13b. WYE Connector Terminal Shown with Both Heat Shrink Tubing Shrunk. Doc No.

Scout-3000 4-20mA Port Setup The 4-20mA Port Setup menu allows you to configure the optional 4-20mA current output loops. The term Channel reflects which gauge sensor is connected to the current loop. The single 4-20 mA card is channel 1. The 4 mA allows you to set the value that the 4 mA of current will reflect. In the example in Figure 50, a reading of 0.0 PSI will output 4 mA. The 20 mA allows you to set the value that the 20 mA of current will reflect. In this example, a reading of 5000.
TROUBLESHOOTING Sensor To Surface Communication Troubleshooting The definitive method for troubleshooting installation problems is to separate the downhole equipment from the surface equipment, including the junction box and surface cable. Once this is done the ability is gained to truly see where the problem lies with the installation. THE USE OF A MEGGER IS STRICTLY PROHIBITED DURING THIS TEST UNLESS ALL OTHER AVENUES ARE EXHAUSTED.
Scout-3000 Troubleshooting Before attempting to troubleshoot there are a few general items you should double check: Check that all connections to the fuse block and three phase choke are correct. Check the fuse on the fuse block. Check the fuses in the Scout-3000 (line circuit breaker and gauge signal fuse). Check for a short circuit in the motor power circuit. Make sure you have a dedicated ground wire from the Scout-3000 directly to the wellhead ground.
Figure 51. Scout-3000 Main Display Select “SPS Menu”. Figure 52. Scout-3000 System Menu Select “Operation Settings”. Select Operation Settings Figure 53. Scout-3000 SPS Setup Menu Select “Set Voltage” to change the SPS voltage. Doc No.
Select Set Voltage Figure 54. SPS Operating Settings Menu After changing the voltage, the voltage will be set on the SPS. (Set Voltage cannot be saved with Auto Volt turned on) Now turn off the Scout-3000 and turn it back on again. If you still are receiving errors then repeat the above process incrementing the voltage by 4 volts. Continue repeating this process until the Scout is reading the gauge data. It will take around 12 minutes to begin receiving tool data.
SPS-1500 Troubleshooting The SPS-1500 may experience communication problems due to noisy environments, grounding problems, or installation issues. The LCD on the SPS-1500 will display certain error codes depending on the failure the controller is detecting. Below is a list of common error codes and possible solutions to assist with troubleshooting the SPS1500.
