Training

This interactive one day Borehole Image (BHI) awareness course is designed to provide an understanding of the advantages and limitations of current BHI devices, together with their applications and value to the Exploration-Appraisal-Production cycle. The course focuses on sedimentological and structural interpretation techniques, as well as methodologies for wider BHI integration with other data types. For these purposes, the course uses the Badley Ashton geologically-driven workflows and classification schemes for the different facets of the BHI interpretation.

 

• Borehole Image and dip data principles

• Informed tool choice - comparison of the available BHI tools and their geological interpretability

• Recent developments (Quanta Geo/NGI, StarTrak)

• Data acquisition, processing and loading - the big points for discussions with Vendors

• Image display optimisation

• An overview of the QC of the image and dip data

• Introduction to petrophysical BHI applications

 

• The work process and descriptive schemes

• Recognition of sedimentary, diagenetic and structural features

• Manual vs automatic dip interpretation

• Image facies identification and classification

• Structural dip evaluation and zonation

• Palaeoslope and palaeotransport analysis

• Fracture/fault analysis

• In situ stress determination

• The relative value of core-derived and BHI-derived datasets, and their effective 'marriage' (including CT core scans)

• Upscaling the BHI observations - depositional evolution and reservoir architecture interpretations

 

• Examples of deepwater projects integrating core, BHI, and CT scan data for reservoir architecture and fracture network determination

• Examples of BHI projects from other sedimentological environments (aeolian, fluvial, carbonate)

• Additional case studies from the client's own portfolio (assuming previous consultancy work by Badley Ashton)
