Fracturing of Vertical and Horizontal Wells
Program Overview
Hydraulic fracturing turns low-permeability rock into productive reservoir, but results depend on understanding stresses, fluids, proppants and how fractures grow. This course covers rock mechanics and in-situ stress, fracture geometry models, fracturing fluids and proppant selection, diagnostic injection tests and pressure analysis, treatment design for vertical wells, and multistage completion methods for horizontal wells such as plug-and-perf and sliding sleeves. Participants also study execution, quality control, flowback and post-fracture evaluation, with examples from tight gas and unconventional developments in the region and acid versus proppant fracturing choices in carbonates.
Learning Outcomes
- ✓Estimate in-situ stresses and rock properties from logs and tests for fracture design.
- ✓Compare fracture geometry models and predict fracture height, length and width for a design case.
- ✓Select fracturing fluids and proppants based on reservoir temperature, closure stress and conductivity needs.
- ✓Interpret diagnostic fracture injection tests to determine closure pressure and leak-off.
- ✓Design a multistage completion for a horizontal well, including stage spacing and perforation clusters.
- ✓Evaluate post-fracture performance using production and pressure data.
Target Audience
- Completion and stimulation engineers
- Production and reservoir engineers in tight and unconventional assets

Training Methodology
Applied Project & Assessment
Applied Project
Participants design a fracture treatment for a provided tight gas well, either vertical or horizontal, including the stress profile, fluid and proppant selection, DFIT interpretation, a pumping schedule or stage design and a post-fracture evaluation plan.
Assessment
Short diagnostic at the start, practical tasks linked to each learning outcome, and evaluation of the applied project against published criteria.
