WORKSHOP 1

Core Analysis Back to Basics

 

Instructors: Pat Lasswell and Raymond Bruce, Weatherford Labs

Date: Saturday, June 17, 2017

Time: 8:00 a.m. - 5:00 p.m.

Place: Meeting Room 16

Fee: $375.00 for registered attendees; $575.00 non-registered (includes lunch)

About the Course

Back to Basics, a review of the analytical processes which provide the basic rock properties of Permeability, Porosity and Fluid Saturations. The course is designed for those who are relatively new to the profession as well as for those who are “seasoned”.  Conventional and unconventional materials will be covered, but an emphasis will be given to the unconventional analytics.

Within the main test categories, the following analytical methods will be covered:

  • Permeability: Steady-State, Unsteady-State, Pressure Decay in Crushed Preparations
  • Porosity: Fluid Summation, Total and Effective Models, Plug vs Crushed
  • Fluid Saturations: Dean-Stark, Retort, Plug vs Crushed

For each of the analytics, the procedural steps will be presented in detail and common variations of a test will be presented as applicable. The methods and their results will be compared and contrasted. Test uncertainties will be discussed. The strengths and weaknesses of each method will be considered as well as the QC steps available to both the investigator as well as the end user.

Several case studies will be presented to explore the applicability of specific analytical methodologies. The question of fit for purpose will be considered for these tests, within the context of unconventional materials.

This short course is designed to provide investigators and data end-users with a better understanding of our basic analytical tools, to open up discussions on the merits of the available tools and to provide a platform for discussing better documentation and analytical transparency.



WORKSHOP 2

Reservoir Geomechanics and Designed Completions with an Emphasis on the Practical

Instructors: Dr. Ahmad Ghassemi, University of Oklahoma, Aaron Burton, UOG Training, Bill Grieser, Halliburton, Roger Reinmiller and Dr. David Martinez, Borehole Image Specialists

Date: Saturday, June 17, 2017

Time: 8:00 a.m. - 5:00 p.m.

Place: Meeting Room 17

Fee: $375.00 for registered attendees; $575.00 non-registered (includes lunch)

About the Course

This course is designed to give geoscience and engineering professionals the tools they need to customize hydraulic fracture designs with geomechanical models. The goal of this one day course is that you will gain familiarity with the techniques required to actively space and design completion stages in a horizontal well in an unconventional reservoir. In order to provide a foundation for the completions discussion we will cover basic rock properties and fracture mechanics first. Then we will demonstrate how to calculate pore pressure, rock strength and principal stresses from log and well test data. These are the fundamental building blocks of any fracture model. Then the often contentious role of natural fractures and mineralogy will be discussed. Natural fractures may both help or hurt a completion strategy and different scenarios will be introduced. Following the geomechanical overview we will discuss completions modelling in detail and the current thinking on how to design staging. We will finish the day with a panel discussion and participant Q&A. 

The following analytical methods will be covered:

  1. Overview of Geomechanics
    1. Basic Rock Properties
    2. In situ stress and why it is important
    3. Calculation of pore pressure
    4. Rock Strength
    5. Stress Fields and the Anderson fault model
    6. Calculation of in-situ stress in isotropic and vertically transverse isotropic mediums
  2. Effects of Natural Fractures and Mineralogy
    1. What is the influence of minerals and rock strength?
    2. What role do natural fractures play?
  3. Hydraulic Fracture Modeling Fundamentals
    1. Fracture Models and Discrete Fracture Networks
    2. Formation Injection Testing
    3. Matching pressures in modeling
    4. Designed staging
  4. Panel Discussion and Participant Q&A

Place: Meeting Room 16

Fee: $375.00 for registered attendees; $575.00 non-registered (includes lunch)

About the Course

Petrophysicists don’t always effectively integrate mud log information with well log data, often due to unfamiliarity with the measurements and recent advances in surface data logging techniques.  The course is intended for those who are relatively unfamiliar with mud logging and those who wish to learn about updates in advanced mud logging techniques.

The following topics will be covered:

  • Advanced Mud Logging
    • Sample control and quality
      • Lag depth
      • Cuttings derived GR
    • Cuttings Measurement

Practical Review of Reservoir Properties and Well Logging

Instructors: Weijun Guo, Halliburton (Coordinator), Geoff Page, Baker Hughes (NMR, Acoustics and Electromagnetic theory and measurements), Xiaogang Han, BP (Pulsed Neutron theory and applications) and Christopher Jones, Halliburton (Formation Testing theory and applications)

Date: Sunday, June 18, 2017

Time: 8:00 a.m. - 5:00 p.m.

Place: Meeting Room 17

Fee: $375.00 for registered attendees; $575.00 non-registered (includes lunch)

About the Course

Our petrophysics society is facing an epic challenge from multiple fronts: commodity price, people transitioning and the need for technology innovation to develop new types of assets with lower costs.  This course is designed for engineers, researchers, and supervisors to develop broad petrophysical knowledge, and learn the most from each logging technology.  An overview on static and dynamic reservoir properties will kick-off the course.  Subject matter experts will then share their knowledge on measurement theory, applications to determine reservoir properties, and representative case studies.  A broad portfolio of downhole logging technology will be covered: EM, Nuclear, Acoustic, Formation Testing and NMR.

  • Application of and differences between resistivity services - shallow to very deep (0-50m), low to high frequencies (0- 1ghz), vertical to horizontal.
  • Pulsed neutron tool theory and applications on reservoir surveillance
  • Acoustic Delta-T to 3D Anisotropy, permeability, fractures, geomechanics, and deep imaging.
  • Advanced theory and applications of pressure testing, downhole fluid compositional analysis, and sampling.
  • NMR capabilities overview and applications on porosity, permeability, rock texture, fluid types and volumes.

The focus of this course is to emphasize the practical applications of well logging tools while enhancing measurement understanding. 

 


WORKSHOP 5

 

Organic Shale Petrophysics – Integrating Triple Combo and Core Data

Instructors: Gary Gunter, Schlumberger

Date: Sunday, June 18, 2017

Time: 8:00 a.m. - 5:00 p.m.

Place: Meeting Room 18

Fee: $375.00 for registered attendees; $575.00 non-registered (includes lunch)

About the Course

The course will review the major factors involved in developing a petrophysical model for black shales. Intelligently constructed log models based on geologic knowledge and known logging tool responses can deliver the answers we need to make appropriate investment decisions. Log models are necessary as no logging tool measures what we really want to know, but the tools do respond to the rocks and fluids in fairly straightforward and predictable ways.

An example workflow will be presented including log quality control, model building/core calibration and hydrocarbon in place estimates. Topics covered will include: Shale core analysis (GRI, SRP, TRA), Vshale/Vclay, organics & pyrite, matrix mineralogy, porosity, saturation and geomechanics. There will also be hands-on exercises for log quality control, quick look log scans, Vshale, DeltaLogR and GIP calculations.



WORKSHOP 6

Horizontal Log Interpretation in Conventional and Unconventional Reservoirs

Instructors: Dale Fitz, John Zhou, Maxwell Dynamics and Jennifer Market, Weatherford

Date: Sunday, June 18, 2017

Time: 8:00 a.m. - 5:00 p.m.

Place: Meeting Room 19

Fee: $375.00 for registered attendees; $575.00 non-registered (includes lunch)

About the Course

Many borehole logging measurements are significantly affected by the inclination of the wellbore. Horizontal well logs are frequently mis-interpreted, which may lead to errors in calculated reservoir properties, production planning, and wellbore stability.

This course begins with a detailed review of the effects of horizontal wellbores on each logging measurement.  Both conventional and unconventional reservoirs will be considered in detail.  Methods for correctly addressing the horizontal logging effects will be discussed for each tool.  The students will be presented with multiple field example datasets to work through the correct processes for integrating logging data in horizontal reservoirs.
