Engineering What Lies Beneath: How Dr. Mojtaba Moradi Is Powering a Smarter, Lower-Carbon Energy Future
Digital Version In the global energy conversation, attention is often drawn to what is visible – production volumes, infrastructure, market shifts, and policy debates. Yet the real determinants of performance, efficiency, and sustainability are frequently hidden far below the surface, embedded within complex geological systems that resist certainty and demand precision. It is in this invisible domain that Dr. Mojtaba Moradi has built his career. As Subsurface Engineering Manager at TAQA, Dr. Moradi operates in one of the most technically demanding environments in the energy industry – where incomplete data, geological variability, and operational constraints intersect. But rather than viewing uncertainty as a limitation, he has consistently treated it as an opportunity. “The subsurface is one of the most uncertain environments we work in,” he explains. “What drew me to this field was the ability to transform that uncertainty into actionable insight and measurable value.” Over more than 15 years, supported by a PhD in Petroleum Engineering, he has developed a body of work that reflects this philosophy – turning complexity into clarity, and engineering solutions that simultaneously enhance production, reduce waste, and lower environmental impact. At a time when the industry is under increasing pressure to deliver energy more responsibly, his approach offers a compelling blueprint: one where performance and sustainability are not competing priorities, but outcomes of the same intelligent design. A Career Defined by Complexity – and the Pursuit of Better Answers Dr. Moradi’s journey into subsurface engineering was shaped by a fundamental question: how can engineers make confident decisions in environments defined by uncertainty? While academic training provided him with a strong theoretical foundation, it was his hands-on experience across diverse reservoirs that sharpened his ability to navigate ambiguity. Each reservoir presented a different set of challenges – varying rock properties, fluid behaviors, and production constraints – requiring not just technical knowledge, but adaptability and judgment. Over time, he began to see a gap in traditional approaches. Subsurface disciplines – reservoir engineering, completions, production – were often treated as separate functions, each optimised individually. But real performance, he realised, depended on how well these elements worked together. This insight led him to develop a more integrated approach, combining reservoir engineering principles with advanced completion technologies to create solutions that address challenges at their source rather than reacting to them later. That ability to connect disciplines – to think beyond silos – has become a defining feature of his work, enabling him to deliver outcomes that are not only technically robust, but operationally efficient and environmentally aligned. From Reactive Systems to Intelligent Control One of the most significant shifts in subsurface engineering today is the move away from reactive intervention toward intelligent, self-regulating systems. Dr. Moradi has been at the forefront of this transition, particularly through the deployment of Autonomous Inflow Control Device (AICD) technologies. At its core, the challenge these systems address is both technical and environmental. Unwanted water production is one of the most persistent issues in oil and gas operations. It increases energy consumption, requires extensive surface processing, and contributes significantly to greenhouse gas emissions. Traditional approaches often deal with the problem after it arises. AICD technology, by contrast, manages it at the source – within the reservoir itself. “By controlling unwanted water and gas production downhole, we reduce the need for surface processing, lifting and reinjection,” Dr. Moradi explains. “This directly translates into lower energy use and fewer emissions.” The scale of impact becomes evident in one of his flagship implementations in Oman. Initially piloted across 28 wells, the technology was later expanded to more than 300 wells – transforming field performance in the process. The results were striking: a 217% increase in oil production, a 52% reduction in water production, a 51% reduction in carbon intensity, and up to a 73% reduction in energy consumption. These are not incremental gains. They represent a fundamental shift in how subsurface systems are designed – moving from reactive correction to proactive optimisation, where the reservoir itself becomes part of the solution. Sustainability Where It Matters Most While large-scale production improvements are significant, the true test of engineering lies in its ability to perform under constraint. Nowhere is this more evident than in environmentally sensitive regions, where operational decisions carry broader ecological implications. In the Peruvian Amazon, within a protected natural reserve in the Marañón Basin, Dr. Moradi led the deployment of AICD technology in a heavy oil field – a project that required balancing resource development with environmental stewardship. The results demonstrated what is possible when engineering is approached with both precision and intent. Carbon intensity was reduced by up to 56%, greenhouse gas emissions decreased by 64%, and energy consumption dropped by 78%. “What this project demonstrated is that sustainability is not a trade-off,” he notes. “With the right technology and mindset, it becomes a performance advantage.” This perspective reflects a broader shift within the industry. Sustainability is no longer treated as an external requirement or compliance metric – it is increasingly embedded within the engineering process itself, influencing decisions at every stage. Embedding Sustainability into Engineering Decisions One of the more significant, yet less visible, aspects of Dr. Moradi’s work has been the development of environmental modelling tools within TAQA. These tools enable engineers to quantify emissions and integrate sustainability metrics directly into design workflows – bringing environmental considerations into the core of technical decision-making. “This is a major shift,” he explains. “Sustainability is no longer an external metric – it is embedded into the engineering decision-making process itself.” By making environmental impact measurable and actionable, these tools allow teams to evaluate trade-offs more effectively, ensuring that performance improvements are aligned with sustainability goals. This integration marks an important evolution in subsurface engineering – one where efficiency is no longer defined solely by output, but by how intelligently resources are managed across their entire lifecycle. Extending Subsurface Expertise Beyond Oil and Gas As the global energy landscape continues to evolve, subsurface engineering is playing an increasingly important role in emerging energy systems.
