DFIT – The Unconventional Well Test: Theory, Design, and Interpretation


Production and Operations Reservoir Descriptions and Dynamics

Training Course Description

DFIT – The Unconventional Well Test course will review the theory of fracture-injection/falloff testing, the design of DFITs, and interpretation of DFIT data using both straight-line and type-curve methods. Design and interpretation methods will be illustrated with North American field examples, including horizontal and vertical well DFITs in unconventional reservoirs. Additionally, field case studies will be included to show how DFIT interpretations can be used in production data analysis of wells producing from unconventional reservoirs.

Attendees will learn the basic theoretical foundation of diagnostic fracture-injection/falloff test implementation and analysis along with obtaining guidelines for implementing DFIT in field operations. At course end, and attendee should be comfortable with the following:

  • Designing a DFIT
  • Implementing a DFIT design in the field
  • Interpreting DFIT data using commercially-available software packages
  • Using DFIT interpretations in the analysis of production data

Course Duration

The course can be a one-day or two-day course.

Why Attend

All oil and gas professionals working in the development of unconventional reservoirs will encounter DFIT at some point during their career. Since DFIT are the primary well-testing method used in unconventional reservoir development, it is essential to understand the technology, how interpretations are used, and the limitations of a DFIT well test.

Who Should Attend

This course is intended for petroleum, production, completion, and reservoir engineers, geologists and field operation staff who are familiar with the fracturing process and interested in measuring reservoir properties, hydraulic fracturing design, treatment and interpretation, and production data analysis.

Level of Learning

This is an intermediate course. Field guidelines for absolute beginners are provided.

A basic understanding of hydraulic fracturing operations in vertical and horizontal wells is necessary along with a basic understanding of the role of permeability in flow from oil and gas reservoirs.
