Founded in 1982, Geolog provides services in geophysical technology for geological surveillance, safety and control of drilling in the exploration for oil & gas, commonly referred to as mud logging services.

Mud logging is the process of examining drill cuttings (formation rock chips), gas hydrocarbon and its constituents, basic chemical and mechanical parameters of drilling fluid or drilling mud (such as density and temperature), as well as gathering a database of the drilling parameters for Oil Companies onshore and offshore.

Mud logging has evolved over the past decades, from basic data monitoring to providing real-time formation evaluation data during drilling. Mud Logging is a relative low cost service within the overall cost of exploration and production (less than 2% of total well construction costs) with unique technologies to resolve safety issues and help with formation evaluation; it is however critical for modern complex wells - particularly deep water and directional drilling wells. It is in these complex situations that Geolog has focused its expertise and technological innovation.

Geolog´s core services are centred around 3 key industry requirements:

Initially focused on the geothermal and oil and gas wells based in Italy, Geolog has grown significantly in its 27 years of history and now specialises in niche mud logging services dedicated to the oil & gas industry up-stream sector (drilling and production) and currently operates in over 20 countries. The company has in excess of 100 operating units and employs over 850 people, making it one of the largest international mud logging companies in the world. Geolog is presently involved in exploration, development wells, deep offshore and HP/HT wells.

Geolog´s growth is to be attributed, amongst others, to its technological leadership in the mud logging sector and its strong focus on proprietary research and development. As such, Geolog invests heavily in R&D with a target to produce a new patent, on average, every two years. In line with its strategy to be the leading global supplier of choice for highly technological mud logging services to the oil and gas industry, Geolog focuses on those markets where its leadership in highly complex drilling projects is required, recognised, and rettributed. These typically include deep-water, deep-onshore and horizontal drilling with extended reach of up to and over 10 km.

In particular, Geolog is now a world leader in gas detection and gas extraction from drilling mud thanks to its advanced constant volume degasser and dual chromatograph technology.
