Integration of Borehole Image and Petrophysical Analysis

At Geodwipa we provide top-class borehole image petrophysical interpretation services, with the aim to extract the maximum value from your wireline logs or LWD Logs.  We provide specialised training courses in borehole images interpretation for geologists, petrophysicists and geophysicists.

The four day training course covers image log technology and practice (wireline and LWD), QC and processing, structural interpretation, sedimentological characterisation of clastic and carbonate rocks, in-situ stress analysis and Image Petrophysical Analysis/ Image Enhanced Porosity and Permeability. Our detailed focus on integrated analysis of imagelog and petrophysical which are can be critical in successful hydrocarbon exploration and development.

Geodwipa runs both open invitation courses and closed courses for specific clients. Course locations are available worldwide in both cases. Courses can be customised to a client’s particular needs, but typically aim to provide attendees with an insight into how borehole images can assist in reservoir evaluation and the skills required to begin borehole image interpretation.

Schedule

Day 1
Borehole Image Data Processing & QC

  • Complete data loading (including all objects from DLIS tape)
  • Raw curve data checks (e.g. completeness, depth range, curve units, curve statistics)
  • Magnetometer and accelerometer quality control
  • Corrections and recalculation of orientation data
  • Tool offset information and correct application to all time based data
  • Correction for magnetic declination and relative bearing offset
  • Accelerometer corrections
  • Button repair
  • Button equalization.

Formation Image Processing and Interpretation

  • The workshop will introduce borehole image log devices, its limitations and the methodologies used to analyze data for geological objectives in a reservoir
  • The course material used includes clastic successions with well developed cross-bedding, carbonate rocks with intense fracturing and also igneous reservoirs with both secondary porosity through weathering and fracture porosity
  • The participant will interactively work with images from these reservoirs and will be guided by the instructors during their interpretation
  • The emphasis of this course will be placed on how image logs contribute to solving geological problems/questions in a reservoir


Day 2 
Structural Geology for Image Log Interpretation

  • Introduction to the qualitative and quantitative assessment of fractures of different scale (faults with significant offset, slickensides, joints and microfractures), focusing upon structural geology techniques suitable to support and enhance image interpretation
  • Classification of brittle faults and fractures in outcrop, core and log, considering the different scales of observation and resolution
  • Basic brittle structural geology techniques used for genetic fault interpretation and kinematic/dynamic fracture/fault analysis
  • Structural core analysis and the integration of core data with image logs
  • Characterization of the fractured matrix (microfractures, joints) carrying most of a fractured reservoir’s porosity
  • Assessment of fault zones, faults and fault rocks with respect to their contribution to reservoir characteristics

Stratigraphic Evaluation of Formation Images & Interpretation of Depositional Environments

  • Image quality control and “Interpretability”
  • Importance of understanding of the near-wellbore and regional structure to a stratigraphic interpretation
  • Overview of sediment surfaces, boundaries and interfaces with an introduction to sediment architecture
  • Methodical and practical Borehole Image Facies Scheme
  • Residual dips and sediment dispersal to assess palaeotransport and/or palaeoslope
  • Image facies and facies associations to help understanding of depositional environments
  • Terrestrial sediments: Aeolian, Fluvial, Lacustrine systems etc.
  • Coastline and Marine Sediments: Paralic Estuarine, Deltaic, Shoreface systems etc.
  • Deep Water Sediments. Turbidites, Debris Flows, Hemipelagic settling etc.

Fracture System Characterization

  • Fracture/fault identification and detailed analysis utilizing borehole imaging tools, including characterization of in-stress indicators
  • Integration with complementary data e.g. core, outcrop, seismic, petrophysical data and production data
  • Fracture connectivity analysis and fracture corridor recognition
  • Applications in well completion and placement.

Carbonate Reservoirs and Borehole Image Analysis

  • Introduction to Carbonates and Reservoir Properties: a review of carbonates and their terminology.
  • Carbonates and Borehole Images: what images might tell us, and how can we use the information


Day 3
Open Hole Logging and Integration data

  • This course provides a basic background on open hole logs. and how to perform a quick look evaluation of water saturation and mineralogy
  • For each tool type there is a review of the general principles of physics to explain the functioning of the logging tool, and several work sessions on how to use these measurements in well log evaluation
  • Through a combination of discussions and work examples the class will learn how to integrate the quick look evaluation from open hole logs with data from borehole image logs, mud logs, seismic and core data, to develop a more complete understanding of the reservoir and how to use this data in formation evaluation.

Image Petrophysical Analysis – Image enhanced Porosity and Permeability

  • Petrophysical image interpretation is a way of taking the borehole images and producing a grainsize, enhanced porosity and enhanced permeability distribution and vales that describe the rock. Image Enhanced Porosity and Permeability is a method that provides the high resolution porosity distribution, locates the enhanced porosity from low porosity portion and estimates the permeability. In order to do so it uses calculated porosity from high-resolution borehole electrical Images.

Integration of Borehole Image and Petrophysical Analysis Training is designed for geologists, geophysicists, petrophysicists working in exploration and exploitation.
