Applied Formation Evaluation using Techlog Quanti

Applied Formation Evaluation using Quanti adn Rock Typing using SCAL is a practical course that blends theory, hands-on exercises and applied Techlog (Quanti; SCAL).

During the course the  participants will work on triple  quad combo data set  and core data in a continuous interactive learning process;

- from lectures (data interpretation techniques and a quick overview of logging tool principles).

- practical exercises where properties are determined by hand, Excell and in Techlog (Quanti, SCAL) maximizing the use of the software by applying all the available options.

Day 1
  1. Course introduction 
  2. Expectations of the participants
  3. SP and GR Theory
  4. How to calculate VSH and clay type using SP and GR. Results are compared and discussed
  5. Multi-well data analysis and preparation using Techlog tools

Participants will analyze SP and GR data to determine VSH (hands-on and with Techlog) and apply Techlog tools to determine needs for data normalization

Day 2

VSH and Total Porosity Calculations using Density-Neutron.

  1. Review results from previous day
  2. Density measurement and porosity calculation
  3. Neutron measurement and porosity analysis
  4. Density/Neutron combination to calculate VSH and Porosity
  5. Introduction to core data 

 Participants will analyze and use Density and Neutron data ri determine VSH and Porosity (manually and using Techlog).

Day 3

Effective Porosity Calculation and Water Saturation.

  1. Review results from previous day
  2. Compare VSH Results from Density-Neutron vs. SP and GR. Discuss and conciliate results
  3. Effective porosity determination and calculation.  Correction for VSH and Hydrocarbon effects
  4. Introduction to Resistivity measurements and Rt, Ro, Rxo and Rw definitions.
  5. Saturation calculations

Participants will compare and conciliate the different results for VSH to determine the final VSH, calculate effective porosity (manually and with Techlog) and learn about Resistivity measurements. Integration with core measurements.

Day 4
