GeoTech Laboratories utilise advanced analysis technologies to provide high-efficiency solutions to the oil, gas and geothermal industries.

We strive to make today’s laboratory technologies the field services of tomorrow.


GeoTech laboratory services are focused on helping clients to:

· Plan and optimize future wellsite activity, through preliminary tests
· Complete and integrate activity performed at wellsite, by using tools not yet available for field applications
· Test new experimental tools before moving them to wellsite.

Examples of laboratory studies include:
Oil-Oil and Oil-Source rock correlations

· Biomarkers studies on oil and extacts
· Isotopic analyses (GC-IRMS)
Source rock characterization and maturity assessment

· Pyrolysis
· Vitrinite reflectance
· Fluid inclusions
Gas characterization

· Complete chemical analyses, including contaminant gases
· Carbon and deuterium isotopic analyses
· Gas - oil correlations
· Head space analyses
· Residual gas (gas still present in cuttings)
Rock analyses and characterization

· XRD diffraction for mineralogical analyses
· XRF chemical analyses for major, minor and trace elements
· SEM studies


At GeoTech we recognise that ongoing advances in analytical techniques will have a fundamental impact upon the future of decision making within the oil, gas and geothermal industries: enabling multiple high-density data sets generated at the rigsite to replace the high-cost limited data sets previously utilised post-drilling. The availability of enhanced accuracy analysis of samples using technologies formerly restricted to laboratory environments will reinforce this trend, fusing geochemistry with mudlogging formation evaluation to produce new methods of understanding formations in real-time.

As such, GeoTech’s innovation and research are focused to:

· Make available new analytical tools for field applications (towards the future full equipped upstream lab at wellsite)
· Squeeze maximum value from acquired data, to address and solve key industry issues



GeoTech utilises a multidisciplinary group of very young and motivated professionals with PhDs/Masters drawn from a range of academic and industry backgrounds supervised by technical managers with long experience in Oil companies.


The laboratory seeks, via collaboration with a wide range of partners in academia and industry, to leverage advances across a broad spectrum of technologies to create new paradigms for the petroleum and geothermal sectors.

Use of Reservoir Geochemistry in High Water Cut Production: A Case Study in The Karakuş Field
September 2023, IPETGas

Geochemical-based production allocation methods leverage variations between individual reservoirs (EMs) to segregate mixed oil flows, crucial when budget constraints limit options like multiphase flowmeters. This approach, reliant on GC-fingerprinting and deconvolution algorithms, ensures accurate allocation but necessitates diverse chemical profiles among reservoirs for effectiveness.

Placido Franco PhD, Ivo Colombo PhD, Roberto Galimberti PhD, GeoTech

Assessment of reservoir continuity through GC-fingerprinting is widely recognized to provide reliable results and has proven to be effective in supporting or replacing classical approaches such as those based on pressure data analysis. This paper reports an attempt to extend this reservoir geochemistry approach, normally applied to oil sample analysis, to the fingerprinting of cuttings extracts. Challenges, possible solutions and limitations of such an approach, as well as a case history are reported and discussed thoroughly.

Alberto Guadagnini Prof., Anna Russian PhD, Monica Riva Prof., Politecnico di Milano, Eliana Russo MSc, Mario Chiaramonte MSc, GeoTech

Fracture characterization of NFRs plays an important role in hydrocarbon production estimation. Uncertainty propagation from input parameters to model outputs is quantified through a Monte Carlo framework. Stochastic inverse modelling with field data is performed to evaluate posterior probability densities of fracture aperture and to simulate drilling fluid invasion in fractures in quasi-real time during drilling.

H2S detection while drilling: a new approach
March 2019, 14th Offshore Mediterranean Conference and Exhibition, Ravenna, Italy

Luca Mascheroni MSc, GeoTech

Oil and gas reserve contamination by acid gas is a growing issue and H2S occurrence is more and more frequent. The use of organic scavengers in drilling mud prevents the application of techniques routinely used for H2S detection. Geolog has set up an innovative methodology to highlight H2S distribution in reservoir, even in presence of these scavengers.

High Resolution Geochemistry at Well Site, a New Emerging Tool
March 2019, AAPG Hedberg: The Evolution of Petroleum Systems Analysis: Changing of the Guard from Late Mature Experts to Peak Generating Staff, Houston, USA

Mario Chiaramonte MSc, Roberto Galimberti PhD, GeoTech

The recent impressive improvements in analytical chemistry, due on one side to the growing needs of environmental monitoring and on the other to fast developments in nanotechnologies, made possible to move part of geochemical lab activities to wellsite. New portable and more robust instruments, able treplace bulky and complex instruments used in the labs, have been adopted in mud logging units, to introduce geochemistry at well site. This trend is still ongoing and other analytical techniques will be moved soon, offering new opportunities to get in quasi-real time additional high value data, matching lab quality standards.
