A word from a long-standing employee…

July 3, 2017

“Such a long time has passed by between my first job interview in 1992 - at that time GEOLOG HQ was in a tiny apartment in Milan suburbs! - and my current position as Technical Advisor in Luanda. GEOLOG, in the meantime, has become the largest independent Surface Logging company in the world: from a handful of employees providing services only to the Italian market, to more than one and a thousand staff with operations across five continents! More importantly, GEOLOG is now a recognized brand and synonymous of excellent quality of service. We are all very proud of this achievement!”

GEOLOG in the Community

June 8, 2017

During its history, GEOLOG has been actively supporting local charities, focusing on the education and quality of life of young children. For the last few years, for example, GEOLOG has been supporting the Institute Don Bosco in Angola. In 2015, the company donated a water truck to the organization, enabling the over 8,000 children free education on a daily basis and access to fresh water every day.

Recently in Chile, GEOLOG Foundation also organized a social initiative in Punta Arenas (Chile) with a local kindergarten that hosts 104 children aging from 8 months to 4 years old. This type of public kindergarten does not receive sufficient resources to auto-sustain, and most of the families do not have conditions to buy basic materials for the kids. For this reason, GEOLOG provided materials for them and arrange a magic show for the kids.

GEOLOG prides itself on engaging and working together with local communities in the countries where we operate!

More than 3 decades of Mud Logging revolution!

March 16, 2017

By Fabrice Anglereaux, Sub Sahara Region Manager

GEOLOG is celebrating 35 years of existence and I have been here for half of this time! Coming from another Mud Logging company, I was first impressed by the quality of GEOLOG’s material. Some of you probably remember the famous comperf, comgas of the Motorola! We then moved away from our UNIX environment to the current one – a difficult transition especially as we were effectively a rapidly growing startup at the same time! 

During the past years, I have also witnessed the amazing evolution of our Mud Logging units and advanced services equipment. We have learnt a lot and now a very well-engineered and reliable product suite far above any competitor globally. When I joined the company, less than 10 units were working outside Italy in 3 countries. In 2015, GEOLOG had more than 300 units working in over 35 countries with 1700 employees. A true success story!

GEOLOG Logo Evolution

February 8, 2017

The original GEOLOG logo was designed in 1982 when the company was founded in Italy to provide mud logging services to AGIP on geothermal, oil and gas wells. 13 years later in 1995, with the company international expansion, opening bases in Tunisia, Congo and Venezuela, GEOLOG icon became more simplified.

After current management acquired the company in 2001 and when GEOLOG started to develop more innovative solutions, the symbol used since 1995, was replaced, in 2003, to a new version in blue color focused on surface logging and reduction of costs.

The 2013 logo, which is used today, was created to represent innovation, dynamism and consistently grown, reinforcing GEOLOG as the leading independent surface company in the world.
