Overview
Vaalco Energy is an independent oil and gas exploration and production company organized in Delaware and headquartered in Houston, Texas. Its business has historically centered on offshore West Africa, particularly the Etame Marin block off the coast of Gabon. Rather than operating as a large integrated energy group spanning refining, fuels marketing, chemicals, and power, Vaalco has been positioned primarily as an upstream company: it participates in the exploration, development, production, and sale of hydrocarbons from offshore fields. The Etame Marin block has been the company’s principal operating asset and the main source of its revenue. Vaalco holds a 58.8% interest in the block through a production-sharing-contract structure. The concession covers approximately 750,000 acres, or about 3,000 square kilometres, offshore Gabon. Production from this asset has historically been predominantly crude oil, making petroleum the central commercial product in the company’s portfolio. The company’s reported proved reserves as of December 31, 2021 were 11.218 million barrels of oil equivalent, and those reserves were entirely petroleum according to the cited reference material. Vaalco has expanded its West African portfolio through transactions involving both operated and non-operated interests. In 2000, it sold a 32.5% interest in the Etame Marin permit to PanAfrican Energy Corp. The transaction changed the ownership structure of the Gabonese asset while leaving Vaalco with a substantial participating interest. In November 2012, Vaalco acquired a 31% non-operating working interest in a production and development area offshore Equatorial Guinea from Petronas for $10 million. In November 2016, it acquired an additional 3.23% participating interest, equivalent to a 2.98% working interest, in the Etame Marin permit. These transactions illustrate the company’s strategy of building value through selective interests in offshore exploration and production licences rather than through a broad global operating footprint. The company’s activities involve the technical and commercial requirements typical of offshore upstream petroleum operations, including reservoir development, drilling, production management, marine logistics, regulatory compliance, field infrastructure, and crude-oil marketing. Its economic performance is therefore exposed to production levels, field decline and development results, operating costs, contractual terms under production-sharing arrangements, offshore safety and environmental requirements, and international oil prices. Vaalco’s public profile is closely associated with Gabonese offshore oil production. Its Equatorial Guinea position provides additional regional exposure, although the cited material describes that interest as non-operating and identifies an undeveloped portion of the relevant block. The available reference material does not establish a complete current asset list, current reserve position, present-day executive roster, current website, or stock-exchange details; those fields are therefore left unconfirmed in this dossier.
History
Vaalco Energy developed as an independent upstream petroleum company with a strategy centered on offshore exploration and production. Its corporate organization is in Delaware, while its headquarters are in Houston, Texas, a major center for the United States oil and gas industry. The company’s historical operating identity has been shaped less by a diversified international portfolio than by its participation in selected offshore African concessions. The company’s most important asset has been the Etame Marin block offshore Gabon. The block covers roughly 750,000 acres, or approximately 3,000 square kilometres, and has operated under a production-sharing-contract framework. Vaalco’s interest in the block has been the principal contributor to its revenue and production profile. The asset is primarily an oil-producing property, and the company’s reported proved reserves at December 31, 2021 were 11.218 million barrels of oil equivalent, all classified as petroleum in the cited reference. In 2000, Vaalco sold a 32.5% interest in the Etame Marin permit to PanAfrican Energy Corp. This transaction altered the ownership composition of the Gabonese concession while preserving Vaalco’s continuing involvement. The deal is an early example of the company using asset interests and partnership structures to manage participation in offshore projects. Vaalco broadened its regional exposure in November 2012 by acquiring a 31% non-operating working interest from Petronas in a production and development area offshore Equatorial Guinea. The consideration reported for the transaction was $10 million. Because the interest was non-operating, the transaction gave Vaalco exposure to an additional offshore petroleum opportunity without making it the operator of that area. The cited material identifies the relevant Equatorial Guinea position as involving an undeveloped portion of a block and reports a 45.9% working interest in that undeveloped area. In November 2016, the company acquired a further 3.23% participating interest in the Etame Marin permit, corresponding to a 2.98% working interest. The acquisition increased Vaalco’s economic participation in its core Gabon asset and reinforced the importance of Etame Marin to the company’s upstream strategy. Leadership also changed during this period. Cary Bounds was named chief executive officer in December 2016. The available reference does not provide a complete subsequent leadership history, so no additional current or former executives are asserted here. Operationally, Vaalco’s history reflects the characteristics of a focused offshore producer: its results depend on the performance of a limited number of assets, the terms of production-sharing and working-interest arrangements, successful field development, offshore infrastructure, and commodity prices. Its business is distinct from that of an integrated oil major because the available material describes no large refining, retail-fuel, chemicals, or power-generation platform. Instead, the company’s documented activity is concentrated in upstream hydrocarbon exploration, development, and production in West Africa.

Products and positioning
Independent upstream oil and gas company focused on offshore West African exploration, development, and production assets.
Upstream petroleum production
Crude oil
Crude oil is Vaalco’s principal documented commercial product. The company’s main revenue source has historically been its participation in production from the Etame Marin block offshore Gabon, and its proved reserves reported at the end of 2021 were entirely petroleum. Production and sales are subject to offshore operating conditions, production-sharing terms, field performance, and international crude-oil pricing.
Upstream petroleum production
Natural gas
Natural gas is included among Vaalco’s hydrocarbon products, although the cited material identifies crude oil and petroleum reserves as the company’s dominant documented output. The available sources do not provide a detailed breakdown of gas production, marketed volumes, or a separate gas-focused product line.
