Oil companies often have very remote oil pumps which are difficult to monitor using traditional Remote Terminal Unit (RTU) equipment because there is no hard wired communication channel available to connect to a central Supervisory Control and Data Acquisition (SCADA) system.

industrial oil beam and ESP pump monitoring

Oil companies generally have a need to know immediate status monitoring and longer term oil well condition monitoring. Such sites may be very remote oil pumps which are visited only occasionally by field teams. These may require a data collection and telemetry system to provide performance and status information on their operation to centrally located staff.

Application Detail

Oil Beam Pump and ESP Pump Monitoring

A typical remote oil beam pump installation would have a pump, a pump engine (diesel) and a pump controller. The pump controller typically would have a microprocessor based small RTU with a Modbus interface and there would be other interfaces, usually 4-20mA analog sensors for temperatures and pressures which are associated with the oil pump.
There are many different brands / types of oil pumps, for example there are beam pumps, jet pumps and electrically submersible pumps. All of these have some form of pump / engine controller. Some have individual sensors typically 4-20mA analog inputs and some have more complex Remote Terminal Unit (RTU) controllers with Modbus interfaces. Some also have control outputs, for example a control output to force a pump shutdown in an emergency.

Unidata has worked with Weatherford EPIC, Lufkin SAM and smaller providers of such systems. All of these have Modbus parameters which can be collected and monitored remotely, and there are limited control functions available, especially a shutdown function, which are possible across a telemetry link.

There may also be requirements to monitor older pumps without sophisticated controller systems. In these circumstances individual sensors can be attached, pressure sensors, temperature sensors and the like may need to be measured. Other local conditions, for example fuel levels, voltages, temperatures may also need to be monitored. These can be attached to analog and digital inputs of a Neon Remote Terminal to be routinely measured and reported on. Perhaps there is an electrically submersible pump that needs to be monitored. This could be accomplished by adding a clamp on current transformer to the pump power supply, so the power input can be monitored, across three phases, and determine the pump load and pump condition.
The Neon Remote Terminals / Modules can be set up to monitor the analog and digital sensors and to Modbus inputs and store readings and operating parameters locally. In most cases, the data is sent on a regular (5,10 or 15 minutes) basis to a central Neon Server to be viewed on a web browser, and sent to associated systems within an organization responsible for managing the oil pumps.

Typically such organization would have an immediate need to display the data on their SCADA systems and they would have a longer term need to analyze the performance data to determine the long term efficiency of the well.
Dynacard graphs are very valuable indicator of beam pump operation and well condition.
The Dynacard can be extracted from the Oil Pump controller, passed through the Neon Remote Terminal and displayed on the neon Applications Software Web browser.
The data could also be scanned for any out of limit condition and activate an alarm and or send an email or a text message to the appropriate people to take any action following an out of limits condition.

OIL BEAM PUMP AND ESP PUMP MONITORING

Consideration needs to be given to providing a power source. If a 12 volt supply is available, then this could be used. If an independent power system is more desirable a small solar panel and battery could be used, with a solar power recharge system. A small enclosure with a lithium battery pack could be added, and this would provide a completely independent power source for the measurement station for more than 2 years, depending on the instrument s chosen.

There needs to be some consideration on requirements for intrinsic safe instruments in this application. For any direct sensors connected to an oil pump, most likely they need to be intrinsic safe, and the wiring from them, most likely, will need intrinsic safe barriers fitted. The specific requirements for each installation need consideration, but generally, it is likely that the Neon Remote Terminal and Telemetry system would be located just outside the zone for intrinsic safe equipment, perhaps 3 meters away from the pump.
