Our History
Since our inception in Hassi Messaoud in 1990, OSCO has evolved from a local operational support provider into a preeminent, multi-disciplinary partner across North Africa and the Middle East’s energy sectors.
Over more than three decades of continuous growth—spanning strategic hubs in Hassi Messaoud, Algiers, Adrar, and the UAE—our journey has been defined by technical precision, operational agility, and an unyielding commitment to safety.
From securing foundational partnerships with industry giants like Sonatrach to pioneering technical milestones as Algeria’s first LEEA-certified entity, we have consistently elevated standards across upstream and downstream services.
Today, our history reflects a proud legacy of reliability: transforming decades of hands-on field expertise into world-class inspection, engineering, and maintenance solutions built for the industry’s most demanding environments.
