Occidental Petroleum Corporation—often recognized simply as Oxy—has woven a remarkable and sometimes controversial path through the fabric of American and global industry. Founded in Los Angeles in 1920, Occidental’s journey from a struggling driller on the West Coast to one of the world’s leading oil, gas, and chemical producers is a story rich in ambition, innovation, and transformation. Over the past century, the company has faced intense competition, fluctuating markets, seismic shifts in technology, and perennial questions about its role in society, the environment, and geopolitics.

This book chronicles the history of Occidental Petroleum, from its modest beginnings to its emergence as a major international player. It is a story shaped by bold visionaries—most notably Armand Hammer, whose expansionist zeal and appetite for risk forged the company’s global rise—and by pragmatic leaders who steered Oxy through the turbulent aftermath of booms and busts. Occidental’s evolving identity has been defined not only by wells, pipelines, and chemical plants but by its ability to adapt: shedding unprofitable ventures, pursuing breakthrough technologies, and forging partnerships across continents.

Yet, the Occidental Petroleum story is not merely one of executives and earnings. It is a window into the American—and indeed global—energy narrative of the twentieth and twenty-first centuries. The company’s fortunes have been bound tightly to questions of resource scarcity and abundance, environmental stewardship, and geopolitical entanglement. From oilfields in California and Libya to chemical plants in Texas, each chapter in Occidental’s history echoes larger patterns of ambition, risk, controversy, and adaptation inherent to the entire energy sector.

In recent decades, Occidental has found itself at the crossroads of immense challenge and opportunity. The acquisition of Anadarko Petroleum, for example, catapulted Oxy to new heights in petroleum production but also brought with it the weighty legacy of past environmental liabilities. Meanwhile, the growing imperative to address climate change and embrace sustainable business models has tested Occidental’s strategic priorities, compelling the company to invest heavily in carbon capture and other decarbonization initiatives. These choices not only reflect shifts within the industry but foreshadow the company’s evolving role in the transition to a lower-carbon future.

Today, Occidental stands as a symbol of both the resilience and adaptability that have long characterized major American enterprises. Its pursuit of innovation, operational excellence, and sustainable solutions demonstrates the possibilities—and the tensions—that shape the modern energy landscape. Under the leadership of trailblazers like Vicki Hollub, Occidental is navigating a world deeply transformed by technological progress, environmental awareness, and shifting societal expectations.

The chapters that follow explore the major turning points, achievements, and controversies that have defined Occidental Petroleum. They offer a lens through which to better understand corporate strategy, leadership, risk, and innovation in one of the world’s most vital industries. As Occidental charts its future course amid the global energy transition, its story remains as timely and instructive as ever.

The year 1920 dawned with a spirit of expansion across the United States, a nation still basking in the glow of victory from the Great War. Automobiles were becoming increasingly common, their internal combustion engines hungry for fuel, and industries hummed with activity, demanding energy. It was against this backdrop of surging demand that, on September 22, 1920, a new enterprise quietly entered the bustling Californian landscape: Occidental Petroleum Corporation.

Founded in Los Angeles, California, the company's very name, "Occidental," meaning "of the West," subtly hinted at its initial geographical focus. The early vision for Occidental was straightforward: to engage in the exploration and production of crude oil, capitalizing on the already burgeoning oil fields scattered across California. The state was, at the time, a hotbed of petroleum activity, and countless small ventures sprang up, each hoping to tap into the black gold beneath the golden state.

Like many fledgling oil companies of the era, Occidental Petroleum started small. Its initial capital likely came from a blend of private investors and local financial backing, a common practice for new oil ventures. The company's operations in these nascent years were entirely centered on domestic oil exploration and production within California. It was a challenging and often unpredictable business, relying heavily on geological intuition and a good deal of luck.

For its first few decades, Occidental Petroleum remained a relatively minor player in the grand scheme of the American oil industry. It was, in fact, an often unprofitable driller, struggling to gain a significant foothold amidst the more established and larger oil giants. The early years were characterized by persistent efforts to locate and extract oil, a period that laid the fundamental groundwork for future growth, even if immediate success proved elusive.

The California oil fields, while promising, were also highly competitive. Numerous companies vied for drilling rights and promising acreage, creating a landscape where only the most persistent, or the luckiest, would thrive. Occidental’s journey through these initial decades was a testament to the sheer difficulty of breaking into a capital-intensive and inherently risky industry. It was a time of learning, of trial and error, and of simply trying to stay afloat in the turbulent waters of oil exploration.

The company's existence during these early years was largely undistinguished. It was a period of quiet perseverance, where the focus was on the painstaking work of drilling, extracting, and transporting oil. While the demand for energy continued to grow, the path to profitability for smaller outfits like Occidental was fraught with financial peril and the constant threat of depletion from their limited wells.

Indeed, by the mid-1950s, Occidental Petroleum found itself in a precarious position, teetering on the brink of bankruptcy. The company was an ailing entity, its prospects looking bleak to most observers. This financial vulnerability, however, would ironically become the very catalyst for a dramatic turning point in Occidental’s story. It was precisely because of its struggles that the company would soon attract the attention of a man whose vision, ambition, and singular drive would transform it beyond recognition.

This quiet, often unremarkable beginning in California, with its struggles and small successes, set the stage for the extraordinary journey that Occidental Petroleum was about to embark upon. The foundations laid in those early years, however modest, would prove crucial when the company's fortunes were dramatically—and unexpectedly—altered by the arrival of a new, influential figure. The stage was set for the entrance of someone who saw not a dying company, but a hidden opportunity.
