Advanced Hydraulic Fracturing: Stepping Beyond
Dr. Ali Daneshy
Although it is generally accepted that industrial hydraulic fractures do not obey simple theories, there is very little discussion of how they actually do behave. In the absence of this knowledge, our usual approach to solving daily fracturing problems is mostly based on “simple” theory, and at times disappointment.
Built on actual field data, this course steps beyond the simple theory and offers new concepts for fracture initiation, extension, closure, proppant transport, conductivity, screen-out, etc. It offers new guidelines for better fracture designs that lead to superior production enhancement at lower cost. Its contents are applicable to all fracturing operations; in horizontal as well as vertical wells.
This course is specifically designed for practicing engineers and managers who want to improve the outcome of their day to day fracturing operations.
Some of the topics covered in this course include;
- Initiation and extension of real hydraulic fractures; reality vs. theory
- Shear fractures and how they alter fracture propagation, proppant transport and production increase. Can we promote them to our advantage?
- Impact of completion design on fracture propagation and production increase; the pitfalls we can avoid.
- What limits fracture height growth in industrial treatments
- Qualitative assessment of fracture conductivity from analysis of fracturing pressure data. What data do we need to collect?
- Matching fracture design with formation properties; one size doesn’t fill all
- What is important about fluid selection and sand concentration?
- Cause and effect analysis of screen-out; fact vs. fiction.
- Interpretation of fracturing pressure data and using it for on-site decisions
- Fracturing fluid rerecovery: where is all the fluid we pumped?
