We provide integrated services on multiple areas of Geoscience. Our partner laboratories located in Portuguese Universities use standardized, industry recognized methods. Our consultants' experience includes the whole geological column, from Precambrian to recent sediments in different regions of the World. All of our work is performed using standard routines and presented in digital format (on paper if requested) through a secure website and/or password blocked files.
Services
Petroleum Geology
Check our services on petroleum asset evaluation, source rock characterization and sedimentology
Training
Our consultants can provide training in several geological themes for techincal assistants, geoscientists, non-technical staff, managers, etc.
Stratigraphy
We provide integrated services on Stratigraphy: Sequence Stratigraphy, palynology, calcareous nannofossils, foraminifera and other fossil groups. Our partner laboratories located in Portuguese Universities use standardized, industry recognized methods. Our consultant's experience includes the whole geological column, from Precambrian to recent sediments in different regions of the World.
Palynology
Multiple organic-walled fossil groups can be analysed from rocks of terrestrial or marine origin. Allows age determination (biostratigraphy), Paleoenvironmental analysis (palynofacies), sequence stratigraphy (quantitative analysis of fossil groups).
Foraminifera
Shell forming protozoa which can provide detailed age determination in sedimentary rocks from the Late Paleozoic to the Quaternary. Equally useful for paleoenvironmental determinations in the marine realm. Either as loose specimens or in thin sections, they can be easily analysed from outcrop, cuttings, side wall core or conventional core samples.
Nannofossils
Some of the smallest fossils you can find, but also some of the most useful for age determination from the Jurassic to recent marine sediments. Even small (ca. 2g) samples may allow a statistically valid quantitative analysis.
Conodonts
Extinct chordates “teeth” that allow high resolution biostratigraphy in Cambrian to Triassic rocks. Usually restricted to core and outcrop samples.
Biostratigraphic campaigns and integration of vintage data
If you are preparing to drill a well we can advise on the sampling campaign. Oil&Gas companies often deal with vintage well reports which are difficult to harmonize with more recent data. Chronosurveys provides the service of re-interpreting old reports and other material, returning revised well tops, sedimentation ages, well correlation and other types of interpretation as requested.
Mineral exploration and metamorphic terranes stratigraphy
Obtaining valid stratigraphic data from Precambrian sediments and low-grade metamorphic rocks is often seen as impossible. Careful sampling and processing coupled with innovative observation techniques (reflected light observation, thin sectioning) opens a new perspective in the study of these rocks. Our consultants have the expertise on these difficult samples. Contact us to know more.
Petroleum GeologyPetroleum asset evaluation
Need to evaluate the hydrocarbon value of an asset in a data room or bid round? We can interpret the available seismic, well data and assess the prospects in terms of volumes and geological risk.We also provide regional prospectivity reports
Source rock analysis and thermal maturation
We provide a comprehensive array of analyses to evaluate source rocks and the thermal maturation of a Petroleum System. Services include kerogen typing, palynofacies, Total Organic Carbon (TOC), RockEval and Thermal Maturation (Vitrinite reflectance, organic matter fluorescence, spore color).
A SPdP - Sociedade Portuguesa de Paleontologia em colaboração com a Chronosurveys Lda. atribuem anualmente o Prémio Paleontologia e Estratigrafia Portuguesa, destinado a galardoar artigos ou teses de licenciatura, mestrado ou doutoramento de excelente qualidade, no domínio da Paleontologia e/ou Estratigrafia.
