Integrated Petrophysics for Unconventional Reservoirs (UCR03)


    This course will equip the petrophysicist with the skills necessary to acquire and evaluate the essential data for each unconventional reservoir type and the reviewer to judge if petrophysical results are fit-for-purpose. The course outlines the geological, engineering and petrophysical characteristics and risks of each unconventional reservoir type. Types include Shale Gas (primary focus), Tight Gas, Oil Shale, Coal Bed Methane, Methane Hydrates, Geothermal and CO2 Sequestration. Armed with this knowledge the minimum petrophysical data sets and integration techniques required to estimate reserves and producibility are explained. The course covers Quick Look to full mainstream integrated methods including how to recognise and avoid the common problems of petrophysical interpretation in unconventional reservoirs. Examples of common log analysis failings and the detailed, specific procedures designed to avoid them are explained simply and clearly.

    Course Level: Basic
    Instructor: Mark Deakin

    Designed for you, if you are...

    • A petrophysicist seeking to future-proof your career with an essential petrophysical understanding of unconventional resources
    • A geologist, operations geologist, structural geologist, geo-modeller, reservoir engineer, well test engineer, geophysicist or core analyst who will create or use petrophysical results for any unconventional resource

    The relevant logging tools, core analysis, fracking and testing techniques are reviewed; however some familiarity with formation evaluation is desirable.

    How we build your confidence

    • Resources are dealt with one by one but with frequent cross-reference, comparison and contrast to enhance the characterisation of each. The basic geological setting is explained, with examples, and the mechanical/engineering requirements which that geology demands is explained, again with examples such as the dewatering and pressure reduction of CBM cleats or the stress orientated drilling and hydraulic fracking of brittle, organic shales.
    • The petrophysical evaluation objectives are then clearly laid out within this framework which leads to the logical choice of data acquisition for that particular resource.
    • Learning is consolidated by comparing and contrasting the cost-benefit of data acquisition schemes which are familiar to the class.
    • Finally, for each resource, the interpretation and log integration of the various data types is performed, from direct measurements to log responses and answers. The more popular interpretation techniques are compared and ranked by class discussion and votes. Daily morning recaps revise and highlight the essential data, problems and evaluation processes.

    Data covered includes Drilling, Core, SCAL, LWD, LithoScanner, NMR, Dielectric, Sigma, Acoustic, Image-logs, MDTs, Fracking (process) and Testing. Recommendations for mudlogs, core, LWD, Wireline and testing are made for each resource type including special core analysis, where appropriate. Basic, expandable templates are provided for each resource type which may be implemented as xls sheets or as petrophysical software scripts. The course progresses via a series of interleaved theory, micro-practicals, demos, workshops and occasional movies to reinforce key facts.

    The benefits from attending

    By the end of the course you will feel confident in your understanding of:

    • The geological and physical nature of each major unconventional resource type
    • The mechanical/engineering setup that each type requires for development
    • The key data and evaluation necessary to develop and manage the resource cost-effectively
    • The key stages and essential petrophysical techniques for each resource together with a basic appreciation of popular rival methods
    • How to check if received petrophysical results are fit-for-purpose or just a table of numbers
    • The pitfalls and uncertainties waiting for you - and how to recognise and circumvent them
    • Major unconventional and future energy sources and how to become a source of guidance and insight during those discussions


    Unconventional Resources are discussed in proportion to the number or wells drilled in each resource per year and/or the class requirements and feedback. The course is responsive and flexible.

    • Geological setting of each major unconventional reservoir type
    • Storage mechanisms, porosity types, key resource parameters (TOC, brittleness, etc.)
    • Engineering setup required by that geological setting
    • Formation Evaluation (FE) objectives for each resource
    • Minimum data acquisition required to assess reserves and production profiles for each resource. What is the required reference data?
    • Common failings of log and data acquisition in terms of its proper objectives
    • Quick Look log analysis
    • Major steps in core-log-test integrated petrophysical evaluation for each resource
    • Primary uncertainties and their circumnavigation/minimisation
    • Typical log analysis pitfalls and failings - how to avoid them
    • Major rival methods compared, contrasted and ranked vs. correct FE objectives
    • Greenlists (checks) for data acquisition, evaluation and results
    • Your method vs. class agreed optimal method (class interactive)
    • Quick Look evaluation templates
    • Useful equations
    • What really matters? How to deliver it
    • What is netpay in this unconventional resource?
    • Key recommendations for data acquisition and evaluation
    • Daily interactive petrophysical demos, micropracticals, workshops, recaps, class discussions
    • Petrophysical toolbox for unconventionals
