Petrophysics Summer School 2017

Physical properties of ocean sediments and basement from downhole logs and core

NEWS: Petrophysics Summer School receives formal CPD accreditation!


Looking at tools used in downhole logging

Petrophysics is the study of the physical (and chemical) properties of rocks and their interactions with fluids, and integrates downhole in situ data from logs with core and seismic data. This has significant applications in the hydrocarbon industry in terms of both exploration for, and production of, oil and gas. It is also an important component of the International Ocean Discovery Program (IODP) in helping to answer the many and varied questions posed by scientific ocean research drilling expeditions around the world. The Petrophysics Summer School provides a unique workshop bringing together experts from both academia and industry to give training in the theory and practice of petrophysics and, notably its applications across both IODP and industry. There are few opportunities for training, especially for non-industry researchers, and with recent reports indicating significant skills shortages in the hydrocarbon sector, the workshop attracts a variety of participants. In addition, the summer school aims to strengthen links between IODP and industry, and provide essential training to the next generation of petrophysicists.

This 2nd Petrophysics Summer School will build on the success of the first, which received extremely positive feedback from both participants and tutors.

“…it was very instructive to get the industry involved as well”

“…my expectations were exceeded"

“Well organized workshop with adequate independent tutorials in well logging….. the diverse scientific background of the tutors/speakers/students gave an extra positive element”

Research topics

Borehole data

The main research focus proposed here is downhole logging where in situ continuous measurements are made in the borehole, these are supplemented by continuous and discrete core physical properties data, thus enabling integration of datasets to maximise their potential use in addressing scientific problems. This summer school not only focuses on the interpretation of these data types acquired during IODP expeditions, but also the rationale behind those measurements, the methodologies associated with their acquisition, and their application beyond IODP, in an industry context.

Downhole logging measurements acquired on IODP expeditions can be used to determine the physical, chemical, and structural properties of the formation penetrated by a borehole. These data can be used to aid interpretation of stratigraphy, lithology and mineralogy as well as providing information about formation stress, or drilling-induced deformation. In the event of incomplete core recovery, these continuous datasets may provide the only means of fully characterising the geological formations encountered. Intermediate in scale between core sample measurements and geophysical surveys, downhole logs are particularly useful in the calibration and ground-truthing of geophysical surveys.  Downhole measurements therefore play a critical role in understanding physical properties across a range of scales.

A variety of physical properties measurements are undertaken on the core material recovered during IODP projects including, density, velocity, resistivity, magnetic susceptibility, natural gamma radiation, porosity and colour reflectance datasets. These high-resolution, non-destructive measurements are valuable in characterising lithological units and formation properties. They can also be used to facilitate hole-to-hole correlation and in the construction of synthetic seismograms.


ECORD Logging Summer School workshop

The 2nd Petrophysics Summer School will focus on the application of downhole logging and core physical properties data to scientific and commercial questions. The workshop will include lectures, discussion groups, and practical exercises on the different elements and data types used in petrophysical analysis. In addition, basic training in an industry-standard software package, Schlumberger’s Techlog, will form a core part of the summer school. Sessions within the summer school will fall into one of three categories: those which explain and describe the principles behind petrophysical measurements; those which demonstrate the methods by which petrophysical measurements are acquired; and those which reveal the ways in which petrophysical data can be used in the pursuit of scientific objectives through integration and interpretation.

Following a more general introduction to IODP and ocean drilling, a series of introductory interactive lectures will set the scene, with experts from both IODP and industry providing information on the various petrophysical measurements and methodologies used. Sessions will focus on real-world examples with case studies from IODP and industry. Practical sessions throughout the week may include: demonstrations of physical properties data acquisition; the generation and use of synthetic seismograms; the use of stratigraphic correlation for hole-hole and site-site correlation; and the integration of borehole images with core.

An off-site day is planned which will be divided between: a visit centred on downhole logging activities, including the development, testing, calibration and deployment of downhole logging tools; and a session at the British Geological Survey (BGS) National Core Repository where participants will have the opportunity to compare a set of cores with the corresponding downhole logging data.

Learning outcomes

The central goal of this summer school is to equip participants with a working knowledge of downhole logging and core physical properties data acquisition and application, for participation in IODP expeditions and also for use more widely, including within industry. By the end of the workshop the participants will:

  • Example MagSus datahave a working knowledge of petrophysics, including a basic understanding backed by a consistent vocabulary that enable good communication between discipline specialists;
  • be familiar with the principles and limitations of the different measurements, and how data are acquired;
  • be aware of the ways in which petrophysical data can be useful in addressing the scientific objectives of a wide variety of projects;
  • have an understanding of the ways in which industry utilise petrophysical data;
  • appreciate how a multi-sensor core logger can provide continuous core data;
  • gain an understanding of how continuous downhole logging data is acquired;
  • be able to use an industry-standard software package, and undertake basic tasks such as data loading and data analysis;
  • be familiar with the concept of core-log integration;
  • be able to apply knowledge to design a logging plan for an expedition.

Location and organisation

The 2nd Petrophysics Summer School will be hosted in 2017 in the Department of Geology at the University of Leicester, UK. The European Petrophysics Consortium and its collaborators offer this unique training opportunity for a summer school through the provision of technical and scientific expertise in the fields of downhole logging and core petrophysics. The majority of the workshop will take place on the main campus of the University of Leicester. There will also be a local, off-site component.
