Description

This NSI Technologies course is designed for engineers involved in detailed design and analysis of hydraulic fracture treatments. A good understanding of, and familiarity with, fracturing fundamentals, materials selection (fluids/ proppant), and applications is required. Emphasis is placed on analyzing fracturing pressure data during pumping, and during the subsequent pressure decline, and use of this data to recognize common problems.
A wide range of real field problems will be tackled in the practical sessions (which comprise more than 50% of the course)

The “workshop” format for this course uses examples of actual problem wells from various environments. These examples place emphasis on 3-D fracture modeling for analysis/design, and the sessions are conducted using NSI’s fracture simulators StimPlan/E-StimPlan. The course includes NSI’s comprehensive manual, augmented with special material discussing fracturing in complex formations. This also includes multiple, detailed, solved case histories ranging from Australian tight gas wells, to Gulf of Mexico "frac-packs", to North Sea tip screenout (TSO) treatments.
Practical applications during the week are built on complete, detailed, real field problems. This format, used very successfully in other courses, enables participants to work with many real field examples and thus gain a deeper understanding of the subject in a short time. Participants are encouraged to bring data sets from their own fractured (or fracture candidate) wells for use in the practical sessions.

*Participants will need to bring a laptop with Microsoft Excel to each day of this course*

Who Should Attend

Primary requirements for this "2nd" course are:
Attendance at NSI Hydraulic Fracturing Course,
or
Basic familiarity with:
- Fracturing pressure analysis since we jump right into this,
- Basic fracture design variables (Height vs. In Situ stress,
Modulus, Fluid Loss Coefficient, and Tip Toughness),
- Fluids and fluid viscosity.

The course is designed for engineers involved in detailed design and analysis of hydraulic fracture treatments.

The course does use NSI's StimPlan simulator as part of the course (as we do for the "Hydraulic Fracturing" course, but to a greater degree), but mostly for manipulating data, doing plots, etc. More than 50% of the people who have taken this course do not routinely use StimPlan, and this has never created a problem. We purposefully try our best NOT to make either course a "software" course -- rather we want them to be about frac theory.
