D003 Geological Interpretation of Well Logs (Distance Learning)
D003 Geological Interpretation of Well Logs (Distance Learning)
Business Impact: The ultimate objectives of this course are to be able to use sets of well logs to establish robust correlation schemes, guide well placement and derive property inputs for geological modelling. These skills will enable participants to reduce risk, understand uncertainty, improve success rates, and reduce costs throughout the E&P life cycle.
This course is an introduction to the principles and applications of conventional well logs. It shows how combinations of logs can be used to interpret mineralogy, lithology, facies, depositional environments and key sequence stratigraphic markers such as flooding surfaces. Sessions start by considering the individual measurements but as the course progresses there is an increasing emphasis on combinations of measurements and the trends with depth. The climax of the course is an exercise to produce a robust correlation scheme using data from three wells. The correlation scheme is then used to choose the location for a fourth well designed to intersect the best developed reservoir.
A virtual classroom course divided into 10 webinar sessions (equivalent to a five-day classroom course), comprising lectures, discussion, case studies, and practical exercises to be completed by participants during and between sessions.
Participants receive a complete set of digital lecture notes and a digital copy of the text book “Geological Interpretation of Well Logs” by Malcolm Rider and Martin Kennedy.
Participants will learn how to:
In this class, each individual logging tool is described in terms of basic functions, physical principles and geological interpretation. Log data is then used as a complementary set for lithology interpretation, facies recognition, log sequence analysis and correlation.

This course best suits those beginning to acquaint themselves with logs or those who do not use logs all the time and need a refresher. The course is aimed primarily at inexperienced Geologists and Geophysicists, whether in exploration or exploitation, but is also good for experienced Technologists, Reservoir and Petroleum Engineers, and new-hire Petrophysicists.
For an entry-level petrophysics class, see D083 (Introduction to Petrophysics and Reservoir Evaluation (Distance Learning)) and for a more petrophysical view of the interpretation of well logs, see course N121 (Modern Petrophysical Well Log Interpretation).
To build on the learnings of D003, it is recommended to follow with D517 (Well Log Sequence Stratigraphy for Exploration and Production (Distance Learning)), N451 (Practical Oil-Finders Guide to Siliciclastic Sequence Stratigraphy (Wyoming)), or N011 (High Resolution Sequence Stratigraphy: Reservoir Applications (Utah)). For those interested in carbonates, D073 (Integration of Sedimentology, Petrophysics and Seismic Interpretation for Exploration and Production of Carbonate Systems (Distance Learning)) would be a suitable follow-up class.

Background
Jenny became an independent Petrophysical Consultant in 2002 and has since gained a wide range of experience consulting for operating companies (UK and worldwide), in addition to heading up the petrophysical discipline within AGR/Tracs consultancy. She has provided petrophysical support to a number of Field Development and Appraisal studies as well as planning and implementing core and logging operations on behalf of a number of small Operators. She is a co-leader for a number of ‘Open Air’ reservoir modelling training courses with TRACS training.
After graduation, Jenny joined Enterprise Oil in 1990 as a Petrophysicist working in London, gaining experience in Exploration and Appraisal, as well as equity redetermination. She moved to Aberdeen in 1997 to join the Nelson Field Development Team and ultimately managed data acquisition and evaluation of all the company’s operated developments.
Jenny became an instructor for Nautilus in 2007. She has co-instructed N095 and N033, and tutored N003, all of which are courses that draw upon her skills and knowledge of Geology, Reservoir Modelling, and Petrophysics. Her main fields of interest are reservoir characterisation, integrating descriptive and quantitative core data with logs (old and modern) as part of a reservoir modelling team. She has extensive knowledge of conventional clastic reservoirs (including most North Sea plays), but has also worked with carbonates, volcanic reservoirs, and tight gas.

Background
Martin Kennedy, is a consultant petrophysicist based in Perth, Western Australia. He began his career as a wireline-logging engineer. After leaving the field, Kennedy worked in R&D, for government and for several mid-sized British independents before moving to Perth as Woodside’s Chief Petrophysicist in 2003. He left after six years to concentrate on training and consulting. His career has spanned everything from field studies to quick-look evaluations as well as managing the petrophysics skill-pool for two companies. Kennedy has worked on most of the classic petroleum provinces outside North America (and a few within) as well as some more exotic areas. He now consults for a wide range of companies ranging from small Independents to Majors and specializes in areas that do not readily yield to standard techniques. His particular interests are carbonates; the way logging tools interact with geology; image logs; and interpreting old logs, bad logs, and bad/old logs. Kennedy holds a degree in chemistry from Bristol U. and a PhD degree in electrical engineering from Edinburgh U.
