Core Descriptions

Our Core Description Services

Siliciclastic Core Descriptions

Documenting grain size, sedimentary structures, facies, and diagenesis to interpret depositional environments, reservoir quality, and stratigraphic architecture.

Carbonate Core Descriptions

Characterising textures, fabrics, allochems, pore systems, and diagenetic overprints to unravel complex carbonate depositional and diagenetic histories.

Evaporite Core Descriptions

Describing mineralogy, fabrics, textures, and deformation features to support basin analysis, seal assessment, and subsurface stability evaluations.

Siliciclastic Core Descriptions

Core logging of siliciclastic rock formations is at the forefront of MGPalaeo’s sedimentological capabilities, stemming from decades of combined outcrop and subsurface experience in various sedimentary basins across the globe.

Detailed to overview digitised core description (1:15 to 1:200 scale) according to client’s needs.

Lithofacies analysis based on sedimentary structures, degree of bioturbation, and accessories.

Lithology characterisation (grain size, sorting, matrix, cements).

Thorough trace-fossil identification and ichnological analysis.

Complete and illustrated paleoenvironmental analysis with ancient and modern depositional analogues.

Optional sequence-stratigraphic approach with identification of stacking patterns and key stratal surfaces.

Flexible reporting formats (slide deck to full manuscript).

Carbonate Core Descriptions

Lithofacies identification from core, cuttings, and image logs.

Texture and fabric analysis (grain types, allochems, matrix, cement).

Microfacies classification and thin‑section petrography.

Interpretation of depositional settings (platform, ramp, reefal, lagoonal, peritidal)

Recognition of high‑frequency cycles and parasequences

Biostratigraphic analysis (age dating).

Early and late diagenetic overprint (dolomitisation, cementation, dissolution, compaction)

Evaporite Core Descriptions

Facies characterisation of halite, anhydrite, gypsum, and mixed evaporite–clastic units.

Identification of primary vs. secondary fabrics (chevron halite, cumulate textures, nodular anhydrite).

Interpretation of depositional settings (saltern, deep‑water evaporite basin, sabkha, playa).

Assessment of deformation features (flow fabrics, shear zones, dissolution collapse).

Recognition of cyclicity and brine evolution trends.

Side Wall Core Descriptions

Lithology characterisation (grain size, sorting, matrix, cements) and identification of structures, bioturbation, and accessories.

Integration with wireline logs and depofacies interpretation.

Integration with palynology for environmental signals and biostratigraphy.

Integration with RCA data for reservoir and seal facies evaluation.

Integration is Key

Our workflows combine multiple datasets to deliver a coherent, high‑resolution interpretation

Core & Slabbed Core Photography

Detailed facies logging, texture analysis, and recognition of subtle sedimentary structures.

Borehole Image Logs

Identification of bedding, lamination, dissolution surfaces, crystal fabrics, and deformation features.

Petrophysical Logs

Integration of GR, density, neutron, sonic, and resistivity responses to refine facies boundaries and cycle thickness.

Thin Section & Petrography

Microfacies classification, diagenetic sequencing, and pore‑type analysis.

Biostratigraphy

Age control through detailed palynological and micropalaeontological analysis.

Sequence Stratigraphy

Understanding the temporal and spatial distribution of sedimentary layers.
