The Case for and Against Using Ball-Drop Multi-Stage Fracturing Systems in Unconventional Horizontal Wells

Abstract

The use of multi-stage stimulation tools to accelerate the process of stimulating horizontal wells has grown at a tremendous rate. In fact, the usage of these systems is currently underwritten by stimulation service companies because time constraints are minimized on 20-plus-stage treatments. However, using these tools can come with a cost. This paper will examine the cost benefit of using these tools in unconventional matrix and naturally fracturedbased gas and oil completions. The authors will present data that will help readers choose a system to meet their needs based on their particular case. Impact on production rate and ultimate recovery, frac fluid imbibition, reduced service costs, risk in running these systems in horizontal wells and other factors will be explored.
