Course overview

This course is concerned with the historical development, physical measurement principles and applications of technologies that were originally designed to obtain the orientation of strata in the subsurface, but are now used to provide a full geological description of the formations crossed by the borehole.

Who is this course aimed at?

The course will be suitable for a wide range of professionals including petrophysicists, geophysicists, geomodellers and reservoir engineers from oil, gas, geothermal, water, nuclear and CCS Industries who have used or are planning to acquire dipmeter logs / borehole image logs as part of their data acquisition campaign.

Learning objectives

1. Demonstrate the main objectives, benefits and limitations of dipmeter and borehole image logs.
2. Describe the principle of downhole navigation systems, dip computation methods and the basic rules for dipmeter log interpretation.
3. Compare the physical measurement principles and tool specifications of electrical and acoustic borehole image logging tools.
4. Evaluate the complexities of borehole image logging in special environments such as oil-base muds, heavy oil, bad hole sections.
5. Explain the basics of processing borehole image logs, quality control of field and processed data and the recognition of acquisition, processing or drilling artifacts.
6. Present the basics of a structural and/or geomechanical interpretation from borehole image logs.
7. Explain the approach towards a sedimentological, textural interpretation of borehole image logs and towards integrated facies analysis.
8. Recommend appropriate borehole image logging tools and processing and interpretation methods in clastic and carbonate environments.
9. Understand the benefits and limitations of borehole image logs in an integrated wellbore analysis. Be able to discuss core – borehole image log calibration issues.
10. Understand the principles and practices of LWD technologies and their use in the evaluation of deviated and horizontal wells.
11. Understand the way in which LWD measurements can identify productive zones and how they can guide the placement of the wellbore towards the most productive parts of the reservoir.
12. Familiarise yourself with a number of non-geosteering applications of LWD technologies.

Speakers

Jurry van Doorn

Jurry van Doorn is a geologist with 35 years' experience in the oilfield service industry. During his career he has focused on dipmeters, geochemical logs, borehole image logs, sidewall coring acquisition and core analysis. Since his retirement from Schlumberger, he has worked as a consultant, most notably with Geode-Energy Ltd.

Dr Melissa Johansson

Dr Melissa Johansson is a geologist with extensive experience in the oilfield service industry (17 years), geology consulting business (8 years) and academia (3 years). She is specialised in applications of borehole image logging technologies for the oil & gas, geothermal and CCUS industries. She recently embarked on a new project involving oil and gas decommissioning.

Iwan Roberts

Iwan Roberts' main field of expertise is the geological and petrophysical characterisation of hydrocarbon reservoirs and the preparation and delivery of technical training courses. During his 30 years with Schlumberger Iwan specialised in Logging-While-Drilling Formation Evaluation and Well Placement. He currently works as a consultant for Geode-Energy Ltd.

Location

This course will be delivered virtually via Zoom. Joining details will be sent out the day prior, alongside any course materials that may be needed.
