Integrated Petrophysics for Unconventional Reservoirs

Integrated Petrophysics for Unconventional Reservoirs

Instructor Mark Deakin, PhD (Petrophysics)

Who Should Attend?

Petrophysicist’s who seek to future-proof their career with an essential understanding of the petrophysics of unconventional resources.  Geologists, operations geologists, structural geologists, geo-modellers, reservoir engineers, well test engineers, geophysicists or core analysts who will create or use petrophysical results for unconventional reservoirs.  Basic logs and core analysis, fracking and testing are reviewed, however a familiarity with these is desirable. Bring your laptop with MS Excel.

This course will equip you with the skills necessary to acquire and evaluate the essential data for each major unconventional reservoir type and to judge if petrophysical results are fit for purpose. The course outlines the geological and engineering configuration of each unconventional reservoir type and the resulting petrophysical objectives and problems. Types include Shale Gas (primary focus), Oil Shale (Light Tight Oil), Tight Gas, Coal Bed Methane, Geothermal, CO2 Sequestration and Methane Hydrates. Time is allocated to each resource in response to class demand and the activity in the region. Armed with this knowledge the petrophysical data and integration methods required to estimate reserves and producibility are explained.  Quick Look to full, mainstream integrated methods are covered including how to recognise and avoid the common misunderstandings and problems with petrophysical interpretation in unconventionals.  Examples of log analysis failings and the specific procedures to avoid them are explained simply and clearly with straightforward techniques on how to apply this knowledge.

Resources types are dealt with systematically, one by one, and compared and contrasted to enhance their characterisation.  The typical geological setting is explained and the mechanical / engineering requirements which that geology demands is explained with, for example, the dewatering and pressure reduction of CBM cleats and the stress orientated drilling and hydraulic fracking of brittle, organic shales.  The relevant evaluation objectives are then clearly laid out for each resource which leads to a logical choice for data acquisition.  Learning is reinforced by contrasting familiar methods with those required for unconventionals.  Finally, for each resource, the interpretation and log integration of various data types is performed, from direct measurements to log responses and answers.  The more popular rival interpretation techniques are then compared and ranked by class discussion and votes.  Daily morning recaps revise and highlight the essential data requirements, problems and petrophysical evaluation processes of each resource.

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

Course Content

Detailed Contents  (Public courses 5 days. Tailored In-House 3 or 5days)

  • Unconventional Resources are discussed in proportion to the wells drilled and investment in each resource per year and to class requirements and feedback.  This course is oversupplied with content and hence responsive and flexible.
  • The geological setting of each major unconventional reservoir type
  • Storage mechanisms, porosity types, the key resource parameters (TOC, Brittleness etc.)
  • The engineering setup required by that geological setting
  • The Formation Evaluation (FE) objectives for each resource
  • The minimum data acquisition required to assess reserves and production profiles for each resource. What is the required reference data?
  • The common failings of log and data acquisition in terms of its proper objectives
  • Quick Look log analysis for each type
  • Major steps in core-log-test integrated petrophysical evaluation for each resource
  • Primary Uncertainties and their circumnavigation / minimization
  • 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. the class’s agreed optimal method (class interactive)
  • Quick Look evaluation templates
  • Useful equations
  • What really matters? How to deliver it
  • What does netpay mean in this unconventional resource?
  • Key recommendations for Data Acquisition and Evaluation
  • Daily Interactive Petrophysical Demos, Micropracticals, Workshops, Recaps, Quizzes, Class discussions
  • Petrophysical Toolbox for Unconventionals

Instructor CV

Dr Mark Deakin is a consultant, author and lecturer in Petrophysical Data Integration. He holds a Ph.D. in ‘Integrated Petrophysics’ from London’s Imperial College, is an ex Amoco petrophysicist, and has more than 30 years’ experience, including 15 as a lecturer and director of PETROPHYSICS Pty Ltd. He has performed over 50 detailed reservoir studies, primarily in Southeast Asia’s difficult carbonate and stacked ‘low-contrast-pay’ reservoirs, keeping abreast of new technologies by technical reading, operations work, attending short courses and lecturing. Mark’s proven approach is to identify and rank reserves uncertainties, then guide companies toward defensible reserves via a process of targeted data acquisition, data-hierarchy and systematic integration. After his Ph.D. Mark authored the first public Integrated Petrophysics course which has evolved into the industry benchmark course for mainstream petrophysics.  Deakin also developed “Integrated Petrophysics for Carbonate & Fractured Reservoirs – A Roadmap”  and the powerful PetroDB-WEB core-log-test linked database evaluation for complex reservoirs. Deakin is a member of SPWLA with offices in Perth, Australia.
