About this event


This course is the VILT condensed version of the industry standard Integrated Petrophysics for Reservoir Characterisation (IPRC) course. The course will teach you how to evaluate reservoirs and quickly identify flawed results. Robust petrophysical results are achieved by the logical, systematic integration of all relevant data - new and old - which is extremely cost-effective compared to the errors resulting from a too-focused, fashionable analysis of part data sets. Integration places each data item in its proper context. This replaces the need to run irrelevant logs, explains apparent data conflicts and provides the correct answer faster.

This course, evolved from a PhD in petrophysics and 30 years of consulting and training, demonstrates how robust answers are achieved by the logical integration of diverse data. Pay and reserves are best addressed by disciplined, logical processes for porosity, saturation, permeability and fluid contacts. Low contrast pay, clastics and carbonates are evaluated by straight forward techniques which outperform any log analysis with direct, plain-to-see results. The integration of all relevant data, including PetroDB’s 30,000 core plug database, is clearly mapped out with the crucial Petrophysics to Geomodel checks set out.

IPRC, presented over 250 times, was the first public integrated petrophysics course (Jan1990) and has been continuously updated with new data and methods to mirror the modern petrophysicist’s real world experience.


  • 5 modules of 4 hours each, delivered over 5 days
  • Pre-course self-learning module
  • Post-course self learning module incl. Q&A opportunity

Course Level: Skill

Instructor: Mark Deakin


  • A petrophysicist, geologist, operations geologist, geo-modeller, reservoir engineer, geophysicist or core analyst, with a year’s experience with logs or formation evaluation

Ensure your laptop is loaded with the provided self-learning modules.

Course content can be adapted to meet the participants' requirements.


All ‘Integrated Petrophysics’ VILT courses have five components to expand and maximise the course content delivery. Content is varied and stimulating and includes short focused instructor videos; course notes extracts; micro-practicals, cornerstone 4-hour daily VILT sessions; before and after self-learning modules; Question & Answer sessions; industry videos, exercises; comprehensive Petrophysical Toolbox; Petro DB extracts; HPV sensitivities; "How to" demos; quizzes & answers

1) Pre Self-Learning module (20%) with a 1-hour live Q&A session before the main VILT

2) Cornerstone VILT: 4 hours of VILT lectures for 5 consecutive days (60%)

- The first 15 minutes of EACH DAY: Recap and Questions session

- The first 5 minutes of EACH HOUR: Questions and feedback

3) Post Self-Learning module (20%) with a 1-hour live Q&A session after one week

4) Instructor is available online for 1 hour extra at the end of the main VILT session for questions & open discussion

5) Instructor is available to answer 1-on-1 emailed questions or possible phone/skype calls for one week after the last VILT session (during Post Self-Learning module)

Before and After Self-Learning Modules

These modules are an important extra component of the course:

  • Pre is designed to focus and prepare you for the main VILT session
  • Post allows you to practise and quiz yourselves and the instructor before closing out the course


This course is a condensed package of powerful integration techniques. It provides a wide array of delivery mechanisms to build a thorough understanding and general template on how to properly evaluate wells and reservoirs.
