Course summary and outline
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.
Part A. Borehole Image data - acquisition, processing and QC
• 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
Part B. Workflows for an effective interpretation
• 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
Part C. Application of the results - case studies
• 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)
Course Information
Instructors
Meriem Bertouche - Meriem is Badley Ashton's CEO and in-house BHI specialist. She is responsible for the quality control of all the BHI work that the Badley Ashton group undertake; she is also responsible for the training of Badley Ashton's staff in BHI interpretation and has particular experience in the Miocene and Oligocene turbidite systems of the Gulf of Mexico, Offshore West Africa and Offshore Malaysia. Meriem has presented this course several times in the past few years.
The course is suitable for geologists, geophysicists, petrophysicists, reservoir engineers and managers who wish to develop a better understanding of borehole image tools and their geological applications. No previous BHI experience is required.
