Summary

 This course addresses the multi-disciplinary technical and economic variables involved in the design and implementation of hydraulic fracturing. This flows from a reservoir evaluation of why/how to frac, to geoscience to quantify many design variables, to frac design and post-frac economic evaluation. Fracture mapping and implementation of multi-stage hydraulic fractures in horizontal wells are included.

Any subsurface activity is inherently the operator’s responsibility and in today’s environment that certainly includes stimulation, specifically hydraulic fracturing. This course prepares attendees to assume responsibility for, or intelligently evaluate stimulation design proposals from a service provider. Or, if not directly involved in detailed operations, this course prepares geologists and geoscientists to understand what input is required from them to optimize hydraulic fracturing.

The course empowers attendees to evaluate if sub-surface fracturing plans are too big, too small, or just right. Either reducing costs, enhancing value, or providing assurance of quality operations.

Feedback

Tutor did an excellent job teaching the course! I learned a lot. It was a very enlightening and enjoyable week.

Duration and Training Method

This is a four-day classroom course which includes classroom lectures with discussion, worked examples, and hands-on exercises.

Course Overview

Participants will learn to:

  1. Recognize the multi-disciplinary nature of hydraulic fracturing involving geoscientist, reservoir engineering, geomechanics, materials selection …….
  2. Assemble pre-frac data
  3. Calculate predicted post-frac productivity
  4. Estimate major frac design parameters (in-situ stress, modulus, fluid loss, and fracture tip effects)
  5. Select appropriate fluid viscosity and pump rate
  6. Select the economically optimized treatment size and proppant program
  7. Select fracturing materials, base fluids, additives, and propping agents
  8. Design and analyze pre-frac testing
  9. Determine stage size/spacing for multiple-fractured horizontal wells

1. Overview

  • Introduction
  • Important Factors in Fracturing

2. In Situ Stress

  • The dominant variable for fracture design
  • Geomechanics - What controls in situ stress and how to estimate this critical parameter
  • The role of geologic structure
  • Proppant stress and how this affects fracture conductivity

3. Reservoir Aspects of Fracturing

  • What controls post-frac productivity
  • How to predict post-frac production
  • How to determine what “type” of fracture is desired
  • Horizontal Well Fracturing
    • Well spacing
    • Cluster/Stage spacing

4. Fracture Geometry

  • Geomechanics aspects of fracturing
  • Major parameters needed for treatment design
  • PNet, Net Fracturing Pressure
  • Horizontal Well Fracturing
    • Effect of fracture interference on fracture geometry

5. Treatment Design

  • How to estimate/measure major design parameters (Height, Modulus, Fluid Loss, and Frac Tip Effects)
  • Data sources
  • Selecting desired fluid viscosity and pump rate
  • Treatment scheduling (viscous gel fracs, water fracs, tip-screenout fracs)

6. Pre-Frac Testing 

  • Step-Rate Test analysis
  • Injection/Decline (DFIT) Analysis
  • Fluid efficiency

7. Materials 

  • Proppant and Fracture Conductivity
  • Fluids and fluid selection process 

The course is designed for mid to senior level engineers and engineering supervisors/managers who are directly involved in hydraulic fracturing design and operations. It is also recommended for geologists, geoscientists and others who routinely supply input data for fracture design optimization.
