Formation Evaluation II

This second unit of the Virtual Mentored Learning (VML) program on Formation Evaluation is designed with a significantly deeper technical coverage of all the key topics covered in Unit 1. Participants will be able to attain Basic Application Competence Level (Level 2) in the formation evaluation of conventional hydrocarbon reservoirs by completing the course and subsequently incorporating the learnings into their job role and work activities.

Guided by experienced industry specialists, participants will cover a series of technical topics that result in a comprehensive understanding of the many components of formation evaluation. The program consists of the following topics at the applied technical level: formation evaluation data acquisition and analysis; open hole well log interpretation; conventional and SCAL core analysis, including the acquisition of full diameter and sidewall cores; advanced well testing and interpretation.

Program Content

Basic Application of Formation Evaluation; Formation Data Acquisition and Equipment; Well Log Interpretation; Use of Conventional and SCAL Core Analysis in Reservoir Characterization; Well Test Design and Interpretation.

Target Audience

Petrotechnical professionals who seek to gain a deeper understanding of all the main aspects of formation evaluation to collaborate more effectively with their multi-disciplinary colleagues. Geologists, geophysicists, reservoir engineers, petroleum engineers, drilling engineers, production engineers and technicians, asset managers and their commercial specialists, as well as early career petrophysicists, would all benefit from this extended course.


This program offers several IHRDC Action Learning modules on select topics, which are each approximately 6 hours of specialized learning supported by the program mentors. One-hour mentor sessions are designed to recap the practical aspects of weekly topics. In total, there are about 40 hours of learning time, equivalent to a one-week full-time training course, delivered in a format enabling the participants to attend their job roles while completing this course.

Learning Formats

IPIMS Action Learning Assignments, virtual mentored learning sessions including both group discussions and, where requested, individual mentoring with participants.

  • The Action Learning self-study component uses IHRDC’s Action Learning modules.
  • Practical assignments will be issued for the participants to complete in parallel with the Action Learning modules, and prior to the associated mentor sessions. The assignments should be completed prior to the virtually mentored meetings, in line with the best practice of “flipped learning” concept. Example answers to the assignments will be supplied after the course participants have completed their assignments.
  • Weekly virtual mentored learning session.
  • All course materials will be available through the dedicated IHRDC learning portal.

Program Content

Week One

Characterizing the Subsurface Environment

The weekly IPIMS e-Learning topic, entitled “the subsurface environment”, reviews the temperature and pressure conditions found in subsurface environments. It discusses the nature and behavior of subsurface waters, fluid pressures, geothermal factors, and the fluid dynamics of sedimentary basins. The topic reviews how these factors can affect hydrocarbons in the subsurface environment.

The practical assignment associated with week one is on the types of multi-disciplinary formation characterization objectives which should be recognized to enable a comprehensive formation evaluation program.

Week Two

Formation Data Acquisition

The weekly content will enable participants to fully understand the objectives and issues with acquiring, viewing, classifying, and validating the multi-disciplinary data and information required for conducting integrated reservoir studies.

In the Action Learning assignment, participants will establish the general formation evaluation data acquisition requirements for an integrated conventional hydrocarbon reservoir field study.

Week Three

Well Log Interpretation

The weekly Action Learning will enable participants to determine the rock and fluid properties using open hole well logs, mud logs, drill cuttings and core data. They will also learn how to evaluate the lithology, mineralogy, fluid distribution, temperature, and pressure gradients, as well as the rock quality.

In the Action Learning assignment, participants will design the data acquisition program for an exploration wildcat well and then conduct a quick-look interpretation of the well logs and select depths for the acquisition of formation pressure data points, fluid samples and sidewall cores.

Week Four

Conventional and SCAL Core Analysis

The week four Action Learning covers the use of well logs, cores, well-to-well correlations, and techniques to establish the distribution of the petrophysical properties within the reservoir.

In the Action Learning assignment, the participants will determine the reservoir properties for input into a field-wide petrophysical model.

Week Five

Well Test Interpretation

The final week’s coverage will enable the course participants to incorporate production data into the reservoir model, along with new data from well and core analyses. Participants will also learn how to refine the reservoir model based on differences between the predicted and the actual pressure and production performance data.

In the Action Learning assignment, participants will review the most currently available data and history-match the reservoir’s actual performance to that predicted by the original reservoir model. Based on the results of the history match, they may modify one, or more, of the following: data summary, grid data, thickness data, porosity data, permeability data, saturation data.
