Core Sedimentology Services
Obtaining full-hole core is a costly process and information from the samples obtained should be maximized. Drill core represents the only tangible sample of the reservoir and thorough investigation of all available cores is required to identify the depositional environment, classify the strata into facies, relate depositional facies to wireline log responses, and identify potential permeability barriers and baffles.
A typical core sedimentology study will encompass the following elements:
Detailed description of the core, including lithology, grain size, sorting, sedimentary structures, bioturbation, fossil content, fracturing, cementation effects and core condition, interpretation of lithofacies, facies assemblages and depositional environments. In heavily bioturbated cores, specialist ichnological analysis is recommended, which uses trace fossil assemblages (ichnofacies) to identify and refine interpretation of depositional environments.
