From Sand to Oil: My Journey at the Cairn Mangala Field

In July 2009, I stood on the sun-baked sands of Rajasthan, staring out at the vast, barren land that stretched as far as the eye could see. At first glance, it seemed like an unlikely place for a significant oil discovery, but this was the Mangala Oil Field, and I had just stepped into what would become a pivotal chapter in my life. Little did I know then that I would spend more than a decade witnessing the transformation of this desolate landscape into one of India's largest onshore oil fields.

When I arrived in 2009, the Mangala field was still in its early stages of construction. Cairn India had already discovered the field in 2004, and now it was time to turn that discovery into a fully operational oil production facility. The scorching heat and challenging terrain made every task demanding, but the excitement of being part of something ground-breaking kept us all going.

During those early days, I was heavily involved in the construction and commissioning activities. Every day brought a new challenge—whether it was dealing with logistical hurdles, ensuring safety measures were met, or coordinating with teams from different parts of the world. The sheer scale of the project was overwhelming at times, but we were all driven by a shared sense of purpose: to unlock the potential of Mangala’s reserves.

Working in oil and gas, you develop a deep respect for the sheer complexity of the industry. The field's infrastructure had to be built from scratch. Pipelines, processing units, power generation systems, and crude storage facilities were all part of the massive undertaking. But for me, the most fascinating part was witnessing the seamless integration of technology with human effort. It was incredible to see how equipment and machinery were designed to handle the specific characteristics of Mangala’s waxy crude oil, which needed special handling techniques, such as heating and insulation, to ensure smooth transportation.

On 29th August, 2009, we had successfully commissioned the field, marking the start of oil production. It was a moment of pride, not just for Cairn but for all of us who had been part of the journey so far. As I watched the first oil being pumped out of the ground, I knew that this was only the beginning.

Once the field was operational, the real test began. Oil production is a continuous and highly complex process, and even the slightest disruption can have significant consequences. The first few years were particularly challenging as we worked to stabilize production levels and implement new technologies to enhance recovery rates.

Mangala’s crude oil is rich in wax content, and transporting it posed a challenge. The pipeline from the field to the refineries is over 600 kms long, and the waxy nature of the oil meant that we had to ensure that it didn’t solidify during transportation. To solve this, we used heated pipelines, which kept the crude oil above a certain temperature. Even though it was a technological marvel, it required constant monitoring and maintenance.

As the field matured, we faced another common issue in oil production: declining reservoir pressure. To address this, we turned to Enhanced Oil Recovery (EOR) techniques. Implementing polymer flooding and now alkaline surfactant polymer (ASP) flooding to improve recovery rates, required a tremendous amount of planning and coordination. Being involved in these projects gave me first-hand experience in how advanced technology can extend the life of an oil field and maximize production.

These technologies didn’t just enhance oil production; they also enhanced my understanding of the industry. Working closely with experts in EOR and observing the application of complex chemical processes in real-time was an invaluable learning experience. Each new step felt like a significant milestone, not just for the field, but for my personal growth within the industry.

One of the most rewarding aspects of my journey at Mangala has been the opportunity to work with an incredibly diverse and talented group of people. The field's success is not just a result of technology but also the teamwork and dedication of everyone involved. From engineers and geologists to safety officers and technicians, it was our collective effort that kept the field running smoothly.

The conditions in Rajasthan were often harsh, with temperatures soaring to over 45°C in the summer. Working in such an environment demanded not just physical resilience but also mental toughness. Yet, despite the challenges, there was a strong sense of companionship among the team. We supported each other through long shifts, tough deadlines, and technical hurdles, always keeping our eye on the ultimate goal: sustaining and improving production.

As the years went by, the team grew more experienced, and our workflows became more efficient. We adapted to changing technologies, market conditions, and even fluctuating oil prices. Through it all, we remained focused on maintaining Mangala’s status as a major contributor to India's domestic oil production.

Looking back on my journey from 2009 to today, it’s astonishing to see how much the Mangala field has changed. What was once a stretch of empty sand is now a bustling oil production hub, complete with state-of-the-art infrastructure and cutting-edge technology. The transformation of the field mirrors my own personal and professional growth. When I first arrived at Mangala, I had a basic understanding of the oil and gas industry, but over the years, I’ve gained a wealth of knowledge and experience that has shaped me into the professional I am today.

One of the most profound lessons I’ve learned during my time at Mangala is the importance of adaptability. The oil and gas industry is constantly evolving, and being able to adapt to new challenges and technologies is crucial for long-term success. Whether it was implementing EOR techniques or managing the logistics of transporting waxy crude oil, each challenge we faced required creative problem-solving and a willingness to embrace change.

As I stand here today, more than a decade after first setting foot on Mangala’s sands, I can’t help but feel a deep sense of pride in what we’ve accomplished. The field has produced millions of barrels of oil, and it continues to play a vital role in India’s energy landscape. But even as we celebrate the past, we must also look to the future.

The oil and gas industry is undergoing a major transformation as the world moves towards cleaner and more sustainable energy sources. While Mangala will continue to produce oil for years to come, we are also exploring ways to minimize our environmental footprint and incorporate more sustainable practices into our operations.

For me personally, the journey at Mangala has been an unforgettable experience, one that has taught me the value of perseverance, innovation, and teamwork. From the initial construction to today’s ongoing production, I have had the privilege of watching this field transform from sand to oil, and I look forward to seeing where the future takes us next.
