Remote monitoring has transformed the operational status of tertiary oil and gas recovery equipment from being "only visible to on-site personnel" to being "accessible anytime on a mobile phone". However, receiving data is only the first step; it becomes effective only when it is viewed, understood, and utilized. Based on the service experience of equipment manufacturers, the most common issue encountered is not insufficient data, but rather the lack of personnel capable of interpreting the data. This article explains the analytical approach to remote monitoring data and the methods for collaboration with operation and maintenance teams.
What insights can be drawn from remote monitoring data
The operational data uploaded by the equipment contains several types of useful information: first, operational status information, such as whether the equipment is operating or in standby mode, and the start and stop times of various components; second, operating condition parameters, including vacuum levels, temperatures, and liquid levels, which reflect the process status; third, alarm and fault information, such as when the alarm was triggered, what kind of alarm it was, and how it was reset.
Looking at data at a single moment is of limited significance; the value of data lies in its trends: whether the number of starts and stops increases or decreases month by month, whether the fluctuation range of a certain parameter has widened, and whether alarms are concentrated in a particular component. Changes in trends often precede the occurrence of faults, which is precisely where remote monitoring excels over on-site inspection in detecting problems earlier.
Five steps of data analysis
- Determine key performance indicators: Work with the manufacturer to identify a list of critical parameters for the equipment at this site. The focus should be on accuracy rather than quantity;
- Set observation cycle: check status daily, observe trends weekly, and summarize monthly;
- Establish a baseline: Use data from the normal operating period of the equipment as a reference, and compare subsequent changes to the baseline;
- Marking anomalies: Any deviation of parameters from the baseline, abnormal start-stop behavior, and changes in alarm frequency are all recorded;
- Joint response: For abnormal items, conduct remote consultation with the manufacturer. If it can be handled remotely, there is no need to wait for on-site response.
Thinking process for interpreting common abnormalities
Several common situations can be interpreted along this line of thought: If the start-stop frequency of equipment becomes noticeably more frequent, first check whether there is a change in the collection volume on the process side, and then check whether there is pressure fluctuation or component performance degradation on the equipment side; if temperature parameters slowly increase, it is often related to changes in the state of the heat exchange surface, and it is recommended to arrange for inspections; if alarms repeatedly occur in the same location, do not just reset them every time, but rather observe the patterns and, if necessary, request a special inspection from the manufacturer.
When in doubt about the interpretation, it is much more efficient to send the data segment to the manufacturer than to verbally describe "the equipment seems to be a bit wrong". With the data in hand, both parties are looking at the same picture, resulting in minimal communication costs.
| Data phenomenon | Possible reasons | Recommended action |
|---|---|---|
| The frequency of starts and stops has noticeably increased | Collection volume variation or equipment pressure fluctuation | Check the process side first, then the equipment side |
| The temperature parameter is slowly increasing | Change in state of heat exchange surface | Arrange for inspection of heat exchange components |
| Alarms are concentrated in the same location | Component performance degradation or change in operating conditions | Observe the pattern and consult with the manufacturer |
| The fluctuation range of parameters has increased | Baseline drift or change in operating conditions | Re-check against the baseline, and mark observations |
| No data upload for a long time | Communication or acquisition abnormality | First, check the network and the acquisition terminal. Do not assume the device is normal |
How can manufacturers assist users in effectively utilizing data
Luoyang Wohong Petrochemical Equipment Co., Ltd. provides users with supporting services for remote monitoring data: parameter sorting and determination of key indicators during equipment access, regular data analysis and feedback during the operation period, and remote consultation and treatment suggestions for abnormal data. The user side only needs to arrange a duty personnel familiar with the equipment to handle the communication, and the daily review, analysis, and judgment of data are completed through cooperation between both parties.
The value of data analysis accumulates over time: once the baseline is established and abnormal records are kept, the high-risk areas of equipment and the consumption patterns of vulnerable parts gradually become clearer. This provides a basis for maintenance plans and spare parts reserves. This approach does not add much extra workload, but it enables operations and maintenance to shift from "passive emergency repairs" to "active scheduling".
Frequently Asked Questions
Can remote monitoring replace on-site inspection?
It cannot be completely replaced. Remote data can show the operating status, but on-site sealing status, abnormal noise, and odor require on-site inspection by personnel. A reasonable approach is to monitor data remotely and conduct regular on-site inspections, with the two lines complementing each other.
Should dedicated personnel be assigned to data analysis?
No full-time position is required. The personnel on duty can spend a few minutes each day checking the status, and the manufacturer provides regular analysis and feedback. In case of anomalies, both parties can conduct remote consultations, which can be done during one's spare time.
Can old equipment be retrofitted with remote monitoring?
Mostly, but it depends on the control configuration of the equipment. Before installation, the manufacturer will conduct an on-site inspection to confirm the communication plan and scope of modification, without altering the original control logic of the equipment.
