This course will teach you how to acquire and evaluate the critical data for each major unconventional reservoir type and to judge if petrophysical results are fit for purpose. The course outlines the geological, engineering and petrophysical characteristics and challenges of each unconventional reservoir type including Shale Gas, Oil Shale (LTO), Tight Gas, Coal Bed Methane, Geothermal, CO2 Sequestration and Methane Hydrates. Armed with this knowledge the 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 the common log analysis failings and the detailed, specific procedures designed to avoid them are explained simply and clearly.

Designed for you, if you are...
A petrophysicist seeking to future-proof your career with an essential understanding of the petrophysics 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 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.
How we build your confidence
Resources types are dealt with one by one and compared and contrasted to enhance the characterisation of each.
The basic geological setting is described and the mechanical / engineering requirements which that geology demands is explained.
The petrophysical evaluation objectives are then laid out within each framework which leads to the logical choice of data acquisition for each resource.
Learning is consolidated by contrasting unconventional data acquisition and evaluation scheme with those 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. Popular interpretation techniques are 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.
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.
By the end of the course you will feel confident in your understanding of:
The geological and detailed physical characteristic of each major unconventional resource type
The mechanical / engineering setup 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 the strenghts and weaknesses of existing popular 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 future energy sources compared: conventional, unconventional, renewable
How to become a source of guidance and insight for your peers during energy discussions
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.
