Let’s start with your early career. What led you to pursue a career in oil and gas, and how did your journey begin?
Olusola: My interest in geology began during my undergraduate studies at the University of Ilorin. I was fascinated by how the earth’s processes could be applied to solve real-world problems. Joining Shell Petroleum Development Company as a studies petrophysicist was a pivotal moment. At Shell, I was introduced to the technical intricacies of subsurface studies, including reservoir evaluation and hydrocarbon maturation.
These foundational experiences shaped my understanding of the industry and motivated me to delve deeper into subsurface management, where science, engineering, and strategic planning intersect to deliver tangible results.
Subsurface studies are a crucial aspect of oil and gas exploration. Can you explain their importance and how they contribute to successful projects?
Subsurface studies are about understanding the unseen—the reservoirs beneath the surface that hold hydrocarbons. These studies inform every stage of a project, from exploration to production. They involve creating detailed models of the reservoir to predict behavior, assess risks, and identify opportunities. For instance, in the Otakikpo field, subsurface studies played a central role in increasing production by providing accurate data to guide well placement and development strategies. Without a thorough understanding of the subsurface, any project would be a gamble.
The OPL310 project is often highlighted as one of your major successes. What were the key challenges, and how did you tackle them?
OPL310 presented several challenges, notably its low resistivity pay zones, which can be difficult to evaluate accurately. These reservoirs require advanced technology and innovative approaches. We introduced Nuclear Magnetic Resonance (NMR) technology to address these challenges, integrating it with traditional methods to improve reservoir characterization. Collaboration was also key—bringing together experts from different disciplines ensured we had a comprehensive strategy. The result was a significant evaluation of the hydrocarbon resource volume, which was deeply satisfying for the entire team.
Field development planning is an area where you’ve excelled. What’s your approach to creating effective plans?
An effective field development plan begins with a deep understanding of the reservoir. I combine deterministic and probabilistic volumetrics to create a robust framework that accounts for both known factors and uncertainties. Collaboration is another pillar of my approach. By involving drilling, engineering, and financial teams early in the process, we ensure that technical and commercial goals are aligned. For the Otakikpo Phase 3 project, this integrated approach allowed us to design a plan that was not only technically sound but also economically viable, leading to a potential production increase of 10,000 bopd.
Technology plays an increasingly important role in the industry. How have advancements influenced your work in reservoir characterization?
Technology has transformed how we approach subsurface studies. Tools like Techlog and Petrel enable us to create detailed static and dynamic reservoir models, while advanced logging techniques, such as dielectric and elemental capture spectroscopy, provide invaluable data for complex reservoirs. Maxhine learning is also making waves, allowing us to analyze large datasets and identify patterns that were previously invisible. This technology has not only improved accuracy but has also reduced the time and cost involved in decision-making.
How do deterministic and probabilistic models complement each other in hydrocarbon evaluation?
Deterministic models provide a clear, single estimate based on fixed parameters, which is useful for establishing a baseline. Probabilistic models, on the other hand, explore a range of possible outcomes by factoring in uncertainties. Together, they offer a comprehensive understanding of the reservoir. For example, in Otakikpo, we used probabilistic models to assess potential production scenarios, which allowed us to mitigate risks and make informed investment decisions.
Leadership is central to managing complex projects. How do you align diverse teams toward a common goal?
Leadership is about creating a shared vision and fostering an environment where everyone feels valued. I prioritize clear communication, setting measurable goals, and providing the resources teams need to succeed.
For Otakikpo Phase 3, I worked closely with stakeholders across drilling, procurement, and finance to ensure alignment. Regular updates and open discussions kept everyone on track, and this collaborative approach was critical to the project’s success.
What’s been your approach to ensuring technical assurance in your projects?
Technical assurance involves rigorous review processes and adherence to industry standards. For instance, during the Otakikpo Phase 3 campaign, we conducted detailed assurance reviews for volumetric assessments using SPE-PRMS standards. This ensured that our resource estimates were accurate and credible, which was crucial for securing stakeholder confidence and funding.
Sustainability is becoming a priority in the oil and gas sector. How do you incorporate it into your projects?
Sustainability is about maximizing efficiency while minimizing environmental impact. In Otakikpo, we adopted energy-efficient drilling techniques and minimized flaring to reduce emissions. We also worked closely with environmental teams to ensure compliance with regulations. These efforts not only protect the environment but also enhance project credibility with stakeholders and communities.
What challenges do you see for subsurface studies in the future?
The complexity of reservoirs is increasing as we explore unconventional reserves. These formations require advanced technologies and innovative approaches. Balancing the cost of these technologies with the need for economic feasibility is a significant challenge. Additionally, as the industry transitions toward greener energy, integrating sustainable practices into subsurface studies will become even more important.
How do you see the oil and gas industry evolving in the context of energy transition?
Oil and gas will remain essential, particularly in developing economies. However, the focus is shifting toward cleaner operations and integrating renewables. The industry must adapt by adopting carbon capture technologies, improving energy efficiency, and investing in sustainable practices. This transition presents both challenges and opportunities for innovation.
What has been the most rewarding project in your career, and why?
The Otakikpo Phase 3 Field Development Plan stands out. It was a complex project that required innovative thinking, collaboration, and technical rigor. Seeing the tangible impact of our efforts—a significant increase in production—was incredibly rewarding. It reinforced my belief in the power of teamwork and strategic planning.
With your extensive experience, how do you stay ahead of industry trends?
Staying ahead requires a commitment to continuous learning. I attend industry conferences, engage with professional networks, and keep up with the latest research. Networking with peers and sharing knowledge also provides valuable insights. The industry evolves quickly, and staying informed is essential to remain competitive.
AI and machine learning are becoming more prevalent. How do you see these technologies shaping subsurface studies?
AI and machine learning have enormous potential in subsurface studies. They enable us to process vast amounts of data quickly, identify patterns, and make more accurate predictions. For example, machine learning models can analyze seismic data to improve reservoir characterization. These technologies are enhancing efficiency and reducing risks, making them indispensable for the future of the industry.
What advice would you give to young professionals aspiring to a career in subsurface studies?
Build a strong technical foundation and stay curious about emerging technologies. The industry is evolving, and adaptability will be a key asset. Seek out mentors who can guide you and challenge you to grow. And most importantly, never stop learning—the field is as dynamic as it is rewarding.
Looking ahead, what’s next for you professionally?
