Vanco Energy Company is a privately held independent oil and gas company whose mission is to explore and develop oil and gas in deepwater worldwide.
Since 1997, with just over 50 people, the company has acquired licenses offshore eight African countries, becoming the largest deepwater license holder offshore West Africa with over 20 million net acres under exploration and development.
Corporate offices based in Houston have expanded to five regional offices in Africa in preparation for drilling and complete operations in 2003. Regional offices are located in Morocco, Ce d'Ivoire, Equatorial Guinea, Namibia and Madagascar.
Vanco has developed an organization and culture to meet the demands of an international operator. Its people are high-energy, creative and pro-active. The management team has years of international experience, most specific to offshore Africa.
As an operator in seven licensed countries, Vanco believes in being a good corporate citizen, and strives to contribute to the communities where it does business by offering scholarships, professional training and assistance with local social programs.
