Celebrating 35 years of field experience

The leading independent surface logging company in the world

We look forward to many more good years to come!

December 4, 2017

“GEOLOG will continue its strategy of cost reduction, eliminating all waste, reviewing its entire production cycle, streamlining the management chain and increasing field staff and management training on new technologies. GEOLOG will also continue to invest massively in Research and Development.

Ongoing collaboration with prestigious universities and a young diversified team of researchers are both key success criteria of GEOLOG’s R&D initiatives. The crucial element of our
success is the enthusiastic team spirit that leverages all disciplines and knowledge bases, across field, base and HQ – everyone works driven by the desire to see GEOLOG succeed.
In the near future we are certain that we will be able to announce new technologies that will fuel another thirty five years of development and expansion for GEOLOG.
To all of you, our most sincere thanks. We look forward to many more good years to come!”, Antonio Calleri, President

Technological progress over the years

November 2, 2017

“Twenty years ago, the unit was equipped with only one PC where all the data of the online well were stored and saved. The software in use can be considered very outdated nowadays (Windows 3.1, database with MS-DOS, etc.). The acquisition and processing system consisted of a Motorola card with UNIX operating system. There were four online printers to plot in real-time and on continuous paper drilling and gas parameter curves, plus another printer to print every minute the alphanumeric parameters. At midnight, the plots were cut and stored in special folders (not like the current virtual printers that automatically generate 24 hours PDFs plots).  After almost 21 years since my first job, a lot has evolved in terms of available technology and client expectations”, Enrico Gemignani - Field Senior Data Engineer - 21-year milestone

Health, safety, the environment and quality are fundamental to everything we do

October 9, 2017

Over the years, GEOLOG’s HSE procedures have constantly improved with ever more awareness of safety on site and rules for implementation. GEOLOG’s vision was always to ensure we meet or exceed all health, safety and environmental expectations of our stakeholders and strive to improve our H, S & E performance on a continuous basis.
In the last years, GEOLOG received many awards for its QHSE performance and several clients worldwide expressed their appreciation to GEOLOG for contributing in achieving important results, such as whole years with no recordable incidents. GEOLOG’s operators have been receiving individual awards for their commitment to comply with the safety rules, policies and procedures and for their professionalism and teamwork at the workplace. This makes GEOLOG extremely proud!

Research & Development Commitment over the decades

September 4, 2017

In just a few decades, GEOLOG evolved from a mono-client company to the leading independent Surface Logging organization with global operations. Today, GEOLOG is present in more than 45 countries and is involved in exploration, development, deep and ultra-deep water offshore, HP/HT, geothermal and unconventional reservoir wells.
The continuous improvement of our technologies and our technical capabilities is a common target pursued by all at GEOLOG. Innovation is part of GEOLOG’s DNA as shown by the important results and solutions developed and achieved year after year. At GEOLOG, we believe our development is never complete and we therefore continuously strive towards the improvement of our systems, equipment and processes.

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!”

Paolo Baldini - Senior Technical Engineer - 25-year milestone

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.
