Carbonate systems

Carbonate petrography

Detailed analysis of limestones, dolomites and associated deposits to reconstruct composition, depositional setting, diagenesis and present-day pore systems.

Blue-resin-impregnated carbonate thin section

A workflow from primary fabric to present-day performance.

Carbonate reservoirs demand careful separation of depositional texture from later alteration. The workflow records both—then connects them to flow-relevant rock properties.

01

Constituent analysis

Identify skeletal and non-skeletal grains, matrix and cements; classify textures using established Folk and Dunham schemes.

02

Diagenetic history

Track cementation, dissolution, dolomitization, recrystallization and replacement, and constrain their relative timing.

03

Environmental interpretation

Relate grain associations, matrix content, sedimentary fabrics and accessory minerals to depositional setting and palaeoenvironment.

04

Rock typing

Characterize present-day composition, pore types, cements, replacements and dolomite textures for reservoir-relevant rock types.

05

Applied petrography

Support reservoir evaluation, geomodelling, petrophysics, rock mechanics and construction-material assessment.

Integrated workflow

Constituents → texture → diagenesis → pores → rock types

Every interpretation is documented with representative imagery and a transparent petrographic framework.
