Coal and shale desorption

Desorption of coal samples (cores) and shale is the basic empirical method used to determine the amount and composition of gas in coal (coal bed methane) and in shale (shale gas).


GEOKRAK offers a wide range of services in the field of environmental geology and hydrology. They include investigations, assessment and forecasting of environmental conditions. For many years we have co-operated with renown Polish and foreign consulting companies, contractors and research laboratories, we have gained experience by carrying out projects.

Mudlogging and Wellsite Geology

Geological services for deep drilling projects constitute the core of GEOKRAK activities. We offer our services and knowledge for oil, gas and geothermal drilling operations. The top quality of our services is guaranteed by qualified staff who expand their skills and knowledge by regular, professional trainings.

Microscope Analyses

Microscope analyses are used in geologic investigations and often supplement final geologic reports or studies (e.g. geological maps, stratigraphic marking of borehole sections, geologic-engineering documentations). They are employed in mineralogic and petrographic analyses of rocks, allow determination of formation ages and also provide information about thermal maturity of organic matter present in rocks. The scope of work may include analyses, final reports or preparation of samples for tests (as requested).

Envinroment Protection

We provide assessment and forecasting of enviroment conditions basing on long-time experience gathered in projects prepared for clients from Poland who operate in the country as well as abroad. The experience let us keep the standards required by both state as well as international companies.

Mapping and GIS

Mapping and GIS section of GEOKRAK provides a broad range of services in structural geology. Our services include both field work as well as studial work which analyze archival materials. Samples taken from outcrops, cuttings and cores from exploration shallow boreholes are given sedimentologic, petrographic and biostratigraphic analyses. For map preparation we use state-of-the-art equipment and software including ArcGIS suite and high-resolution GPS receivers.

Geothermal Energy

GEOKRAK has participated in geothermal energy projects both in Poland and abroad. In the last few years our presence in geotermal projects.

License Applications

We offer preparation of: complete Geologic Work Programmes, applications for exploration, appraisal or production licenses, annexes to Geologic Work Programmes. All documents are based on data and materials provided by the applicant.

Engineering Geology

GEOKRAK offers broad range of services in engineering geology and geotechnics. They include investigation of soil and water conditions of the construction substrate and geologic works necessary for commencement of construction activities.
