Who we are


About us

Great Holdings has been drilling oil and gas wells in Brazil since 2005. It owns eight drilling rigs capable of drilling 2,000 to 3,500-meter deep wells. Based in Rio de Janeiro, it has operations in the North, Northeast and Southeast of Brazil.

In 2015, the company expanded its activities by getting approval from the Brazilian National Agency of Petroleum (ANP) qualifying as C operator and is now able to explore and produce in onshore oil fields. In ANP’s 13th auction round, Oil tapped the first exploration blocks in Recôncavo Baiano.

Efficiency and security ensure economy and reliability

Health, safety and efficiency are Oil’s top priorities, as this ensures the cost-effectiveness of its oil & gas operations.

Our occupational safety policies have ensured excellent rates in operations. On the efficiency side, we ensure high productivity levels with very few downtimes by conducting regular maintenance on our rigs and offering continuous training.

Our CEO is Rubens Botteri. Rubens has extensive industry experience and served as a consultant for Drillfor S.A. in Ecuador, Commercial Director and CEO at Drillfor Perfurações do Brasil Ltda and CEO at Tuscany Perfurações do Brasil Ltda.
