Advanced Carbonate Formation Evaluation with TechLog

This course will focus on the advance interpretation of carbonates.  There will be a strong emphasis on evaluating the parameters that affect carbonates such as “m”, “n”, and microporosity.  Some specific topics that will be covered during this course will include the physics and application of a select number of logging tools with special applications for carbonate interpretation.  Nuclear Magnetic Resonance (NMR) imaging, NMR scanner, acoustic measurements, and acoustic scanner imaging will also be covered.  Participants will also have a chance to learn bout new developments in wireline and LWD neutron logging during this course. 

This course will include 1-2 hours of daily workshop examples and will be most useful to petrophysicists, reservoir engineers, and geologists that work in the carbonate reservoir environment.

Day 1

Carbonate Geology and Dolomitization

  • Carbonate geology and deposition
  • Dolomitization
  • Nuclear Magnetic Resonance (NMR)
  • Acoustic measurements and acoustic scanners  

The first day of this course will focus on carbonate geology and dolomitization.  Other topics that will be covered include deposition, NMR, and NMR-Scanners.  Acoustic measurements and the acoustic scanner will also be discussed.

Day 2

Physics of Logging

  • Borehole imaging
  • Physics of neutron logging
  • Dielectric logging
  • Formation factor applications    
Day two will teach participants about the physics of logging.  Several discussion over borehole imaging using micro-resistivity and ultrasonic imaging will be covered.  The physics of neutron logging using pulsed neutrons for a sigma log will be covered.  The day will end with discussions over the physics of dielectric logging, the dielectric scanner, variable-m, and the formation factor applications.Day 3

Wettability and Dual Porosity

  • Wettability and the variable-n
  • Effect of Vugs and fractures on resistivity measurements
  • Dual porosity

On the third day, participants will learn about wettability and the variable-n.  The effect of Vugs and fractures on resistivity measurements will be covered.  Dual porosity will also be covered, to include specific topics such as MacroPorosity, MicroPorosity, and the quantitative evaluation of dual porosity in carbonates.

Day 4

Estimations and the Connectivity Theory

  • Permeability estimations in carbonates
  • Connectivity Theory
  • Flow Units and the Lorenz plots
Day four will cover permeability estimations in carbonates and the Connectivity Theory.  The Connectivity Theory is a new approach for interpretations in carbonates without the use of the Archie Equation.  Flow units and the Lorenz plots will also be discussed on this day.Day 5

Capillary Pressure

  • Capillary Pressure from core analysis and the NMT T2 conversion
  • The J-Function
  • Rock types, Winland, and the ADNOC function

The fifth day will focus on capillary pressure, from both core analysis and NMT T2 conversion.  The J-Function will also be covered on this day.  Participants will have the chance to also learn about rock types, along with Winland and the ADNOC function.
