[16]
. This process of digitalization falls under the broader umbrella of Industry 4.0, integrating technologies such as fiber optics, mid-band 5G, low-power wide-area networks (LPWANs), WiFi 6, and 3GPP networks (including 5G and LTE). These technologies provide connectivity between the oil and gas sector and the global internet, enhancing local networks.

.
On the other hand, Non-Productive Time (NPT), which refers to the periods when drilling or other essential activities are halted or delayed, results in a lack of progress toward project goals. This downtime has significant implications for the efficiency and economics of oil exploration, First, NPT can lead to increased operational costs. During periods of non-productivity, companies are still required to cover expenses such as equipment rental, labor, and support services, even though no progress is being made. This can have a profound effect on overall project economics. For example, Santoso et al.
| [14] | Santoso, T., Ridwan, H., &Widjaja, T. (2022). Cost analysis of non-productive time in oil and gas exploration projects. International Journal of Energy Studies, 14(1), 45–62. |
[14]
found that NPT could increase total project costs by as much as 30%, particularly in offshore operations where equipment and personnel costs are high.
Second, NPT can results in delays in project timelines. Oil exploration projects are typically planned with strict deadlines to optimize production and financial returns. However, when NPT occurs, these deadlines are often missed, leading to extended project durations. This is especially problematic in offshore and remote operations, where logistical challenges make it harder to recover from downtime. McMahon et al.
| [9] | McMahon, R., Patel, S., & Turner, L. (2023). Managing delays and downtime in offshore oil exploration: New strategies for productivity. Journal of Petroleum Technology, 75(2), 98–112. |
[9]
pointed out that these delays not only affect individual wells but can also cause a ripple effect across an organization’s entire project portfolio, delaying future projects and impacting long-term production goals.
Therefore, it is against backdrop that this study evaluates the advancements in real-time monitoring technologies in order to reduce non-productive time in oil exploration.
5. Conceptual Review
5.1. Real-Time Monitoring
Real-time monitoring refers to the continuous observation and analysis of operational data as it is generated. In oil exploration, real-time monitoring systems collect data from various sensors and equipment in real-time, enabling operators to make informed decisions quickly. This approach has revolutionized oil and gas operations by providing immediate feedback on drilling conditions, wellbore integrity, and other crucial parameters, helping to prevent costly incidents or delays. Technologies such as sensors, data analytics, and automated systems form the backbone of real-time monitoring, offering enhanced visibility into subsurface conditions
| [15] | Shah, M., Patel, R., &Soni, K. (2022). Real-time monitoring technologies in oil and gas: Enabling better operational outcomes. Journal of Petroleum Engineering and Technology, 15(1), 45–58. |
[15]
.
Real-time monitoring is particularly crucial in complex environments like offshore drilling, where delays can have significant financial and environmental consequences. By integrating data from different sources, operators can optimize well placement, predict equipment failures, and take preventive measures to minimize downtime

[1]
The emergence of technologies like the Internet of Things (IoT) and Artificial Intelligence (AI) has further improved the capabilities of real-time monitoring, allowing for more accurate and predictive maintenance, thus minimizing disruptions and Non-Productive Time (NPT)

[10]
.
5.2. Non-Productive Time (NPT)
Non-Productive Time (NPT) refers to any period during oil exploration and drilling operations when no progress is being made, leading to downtime. NPT can occur for various reasons, including equipment failure, logistical delays, or unexpected subsurface conditions. These periods are costly for oil companies, as operations continue to incur expenses without producing any output. According to Santoso et al.
| [14] | Santoso, T., Ridwan, H., &Widjaja, T. (2022). Cost analysis of non-productive time in oil and gas exploration projects. International Journal of Energy Studies, 14(1), 45–62. |
[14]
, NPT can contribute up to 30% of total project costs, particularly in offshore drilling operations where equipment and personnel costs are significantly higher.
The oil and gas industry has been focusing on reducing NPT through the adoption of advanced monitoring and automation technologies. Real-time data analytics, predictive maintenance, and remote monitoring systems are some of the key strategies being used to minimize NPT. These technologies allow operators to identify potential issues before they escalate into downtime, leading to more efficient operations and reduced costs
| [1] | Ali, M., Patel, R., & Khan, S. (2023). Technological advancements in real-time monitoring for oil and gas operations. Journal of Petroleum Engineering and Technology, 18(1), 45–61. |
[1]
. Additionally, the integration of AI-driven systems helps in forecasting equipment failures and optimizing drilling performance, further contributing to the reduction of NPT.
5.3. Oil Exploration
Oil exploration is the process of locating and evaluating potential sites for extracting oil and natural gas. This involves geological surveys, seismic data analysis, and drilling exploratory wells to determine the presence of oil reserves. Technological advancements have dramatically improved the efficiency and accuracy of oil exploration, reducing the environmental impact and increasing the chances of finding viable oil reserves. Historically, oil exploration was a time-consuming and expensive process with significant uncertainty. However, with the integration of technologies like 3D seismic imaging, real-time monitoring, and AI, exploration has become more targeted and efficient
| [5] | Ghobakhloo, M. (2020) Industry 4.0, digitization, and opportunities for sustainability, J. Clean. Prod. 252. 119869. |
[5]
.
In recent years, oil exploration has faced increasing challenges due to environmental concerns and the depletion of easily accessible reserves. As a result, companies have been forced to explore more complex and remote regions, such as deep-water offshore locations, which require advanced technologies to manage. Real-time monitoring and automation systems have been instrumental in ensuring that exploration activities are conducted efficiently and safely, especially in high-risk areas
| [16] | Shah, V., Shah, J., Dudhat, K., Mehta, P., & Shah, M. (2022) Big data analytics in O&G industry, in: Emerging Technologies for Sustainable and Smart Energy, CRC Press, Boca Raton and London, pp. 37–55. |
[16]
. These technologies help companies optimize well placement, monitor drilling conditions, and reduce the environmental impact of exploration activities.
6. Theoretical Review
6.1. System Theory
Systems theory originally developed by Ludwig von Bertalanffy in the 1940s, views complex processes and entities as interrelated components that work together to achieve a specific objective. In the context of oil exploration, the entire exploration and drilling process can be seen as a system comprising various interconnected elements such as machinery, human operators, environmental factors, and real-time monitoring technologies.
In oil exploration, Systems Theory posits that the various elements involved in the exploration and drilling processes must work harmoniously to achieve operational efficiency and minimize downtime. Each component of the system (e.g., drilling equipment, sensors, data analytics platforms, and human operators) plays a crucial role in ensuring the overall performance of the operation. When one component fails or underperforms, it can disrupt the entire system, leading to Non-Productive Time (NPT). Therefore, by improving the real-time monitoring of each component, the system as a whole can become more resilient and efficient
| [5] | Ghobakhloo, M. (2020) Industry 4.0, digitization, and opportunities for sustainability, J. Clean. Prod. 252. 119869. |
[5]
.
For instance, real-time monitoring technologies can be viewed as a subsystem within the larger oil exploration process. By continuously collecting and analyzing data from various sensors, real-time monitoring allows operators to identify and rectify issues (such as equipment malfunctions or adverse subsurface conditions) before they escalate into significant downtime
| [1] | Ali, M., Patel, R., & Khan, S. (2023). Technological advancements in real-time monitoring for oil and gas operations. Journal of Petroleum Engineering and Technology, 18(1), 45–61. |
[1]
. This aligns with the key principles of Systems Theory, which emphasize feedback loops, where information from one part of the system can influence the behavior of the entire system. In this case, the feedback provided by real-time data enables quicker decision-making and corrective action, reducing NPT and improving overall system efficiency.
Systems theory also highlights the importance of integration between different subsystems. In oil exploration, technologies such as Artificial Intelligence (AI), the Internet of Things (IoT), and advanced analytics platforms are increasingly being integrated with real-time monitoring systems to create a more cohesive and responsive operational environment. These technologies act as complementary subsystems that support the larger objective of reducing downtime and improving operational efficiency. By analyzing the interactions between these subsystems, Systems Theory helps explain how advancements in one area (e.g., real-time monitoring) can have a ripple effect throughout the entire system, leading to more efficient and productive operations
| [10] | Mousa, A., Shah, M., & Turner, L. (2022). Reducing non-productive time in offshore drilling: A review of real-time monitoring systems. Journal of Energy Technology, 25(3), 98–112. |
[10]
.
Furthermore, Systems Theory suggests that any disruption in the system should be addressed holistically rather than in isolation. In oil exploration, addressing only one issue (such as equipment failure) without considering how it affects other subsystems (such as safety, production, and data flow) can lead to incomplete or ineffective solutions. By adopting a systems-based approach, oil companies can ensure that real-time monitoring not only reduces NPT but also enhances overall operational efficiency, safety, and sustainability.
In conclusion, Systems Theory provides a valuable framework for understanding how real-time monitoring and other technologies work together within the larger oil exploration process to reduce Non-Productive Time (NPT). By emphasizing the interconnectedness of various subsystems, the theory underscores the importance of holistic, integrated solutions to optimize performance. In the context of oil exploration, this approach allows companies to identify and address potential issues before they escalate, thereby minimizing downtime and improving operational efficiency.

8. Conclusion
The study analyzed the transformative potential of emerging digital technologies, such as; artificial intelligence (AI) and the internet of things (IoT), in enhancing operational efficiency and reducing downtime in the oil and gas sector. Nigeria, as Africa's largest oil producer, faces unique challenges in its exploration activities, including aging infrastructure, remote operational sites, and frequent equipment failures, which lead to significant Non-Productive Time (NPT) and operational inefficiencies. Moreover, Nigeria’s oil and gas industry is critical to its economy, contributing over 90% of export revenues and a significant share of government income. However, many of Nigeria’s oil fields and infrastructure are decades old, leading to frequent equipment breakdowns and operational downtime. Nigeria has extensive offshore oil reserves, but the remote nature of these locations makes communication and monitoring difficult, increasing the likelihood of downtime due to delayed responses to equipment failures or environmental changes. The lack of real-time monitoring has historically led to reactive maintenance practices, with operators responding to equipment failures after they occur, which significantly increases NPT.
Therefore, the adoption of AI and IoT technologies, as discussed in the study, offers an opportunity to address these challenges. AI’s predictive capabilities, combined with IoT’s real-time monitoring, can help Nigeria’s oil operators transition from reactive to proactive maintenance strategies, significantly reducing the incidence of equipment failures and operational disruptions. AI can analyze historical data and real-time inputs from IoT sensors to predict equipment failures before they occur. This is particularly crucial for Nigeria’s aging oil infrastructure, where unanticipated breakdowns can lead to significant downtime and repair costs. By implementing predictive maintenance strategies, Nigerian operators can preemptively address equipment issues, reducing NPT and ensuring smoother operations.
Also, Nigeria’s offshore oil fields, located in the Gulf of Guinea, present logistical and operational challenges due to their remote nature. The integration of IoT sensors with AI-driven monitoring systems, as discussed by Shah et al.

, allows for continuous data transmission from these remote sites to central monitoring centers. This real-time data enables operators to detect anomalies in drilling or production operations and take immediate action, reducing delays and preventing costly shutdowns.
Furthermore, the implementation of AI and IoT in Nigeria’s oil and gas sector would not only reduce downtime but also result in significant cost savings. Reducing NPT leads to higher productivity, as operations are less likely to be interrupted by equipment failures or maintenance delays. For an economy heavily dependent on oil exports, improved operational efficiency translates directly into increased revenue and profitability for both the government and oil companies

More so, the reduction in NPT would enhance the attractiveness of Nigeria’s oil and gas sector to foreign investors. By demonstrating a commitment to modernizing operations through digital technologies, Nigeria can improve its standing in the global energy market and attract new investment for both onshore and offshore exploration projects. The global energy landscape is shifting toward more sustainable practices, and Nigeria is no exception. While the country remains heavily reliant on oil and gas, there is increasing pressure to adopt cleaner technologies and improve operational efficiency. AI and IoT can contribute to this transition by optimizing resource use, reducing emissions from exploration activities, and enabling more efficient management of oil fields. This would not only improve Nigeria’s environmental footprint but also align the country with international sustainability standards

In conclusion, the study demonstrates that the integration of AI and IoT technologies has the potential to transform oil and gas exploration activities in Nigeria. By reducing downtime, optimizing operations, and improving the reliability of aging infrastructure, these technologies can help Nigeria address longstanding challenges in its oil industry. For a country so heavily dependent on oil revenues, these advancements represent a crucial step toward greater operational efficiency, economic stability, and international competitiveness. However, the successful implementation of these technologies will require investment in digital infrastructure, training for local operators, and a commitment to ongoing innovation in the oil and gas sector.
