A Houston-based energy conglomerate best known for its natural gas pipeline empire in the United States, established a local subsidiary — Etosha Petroleum Company (Pty) Ltd — to explore for oil in the remote Owambo Basin of northern Namibia, then South West Africa in 1959.
Etosha Petroleum’s directors were US nationals appointed by the parent company, while local legal and administrative duties were handled through representatives in Windhoek to satisfy colonial corporate registration requirements.
There were no Namibian shareholders or government participation at the time — an arrangement typical of pre-independence exploration ventures.
Once incorporated, Etosha Petroleum launched one of the most ambitious geological programmes the territory had ever seen.
Between 1960 and 1962, the company conducted aeromagnetic and gravity surveys covering over 140,000 square kilometres, stretching from the Etosha Pan across the Owambo plains to the Angolan border. These studies confirmed the presence of deep sedimentary formations, some more than five kilometres thick — a strong indication of potential hydrocarbon-bearing strata.
Encouraged by the findings, the company drilled Namibia’s first recorded onshore petroleum well, the Strat-Test-1, in 1964.
The borehole reached a depth of roughly 1,800 metres and penetrated sequences of sandstone, shale, and limestone.
Though traces of oil-stained sandstones and minor gas shows were encountered, no commercial hydrocarbons were discovered.
The results, while disappointing, were scientifically significant. For the first time, detailed subsurface data revealed the structure and stratigraphy of the Owambo Basin.
The exploration confirmed the existence of all key geological components required for petroleum systems — source rocks, reservoirs, and potential traps — even if the right combination for production was not found at that time.
Following the dry well, Texas Eastern decided to withdraw from Namibia. By 1965–1966, Etosha Petroleum was quietly dissolved, and its exploration licence was surrendered to the South West Africa Administration.
The company’s operations were absorbed back into Texas Eastern’s US portfolio as it refocused on natural gas transmission.
In later years, Texas Eastern would itself become part of a succession of corporate mergers, ultimately forming part of Duke Energy Corporation.
Though Etosha Petroleum vanished from Namibia’s corporate register, its legacy endures.
The data, maps, and core samples from its 1960s campaign remain archived within Namcor’s geological database, forming the foundation of modern understanding of the country’s northern basins.
Every onshore survey and drilling campaign that followed — from the 1970s through to the contemporary re-evaluations of the Owambo and Etosha regions — builds upon that pioneering groundwork.
Etosha Petroleum never found oil, but it proved something equally vital: that beneath Namibia’s dry northern plains lay a true sedimentary basin, one with real geological promise.
In that sense, Texas Eastern’s short-lived venture planted the first scientific seed of Namibia’s onshore petroleum industry — decades before the nation itself would come into being.
