Study Summarizes 20 Years of Horizontal Multistage Completions

This paper will cover the most-common types of horizontal multistage fracturing completion systems, with a primary focus on unconventionals.

The innovative idea behind the shale gas revolution was the combination of horizontal well drilling and hydraulic fracturing, which allowed for an increase in the surface area available for hydrocarbon flow and overcame the slow, shallow hydrocarbon release from the source rock. To achieve the high number of hydraulic fractures needed for economical production, different execution techniques evolved in what became known as horizontal multistage fracturing (HMSF) completions. The complete paper covers the most-common types of HMSF completion systems and includes a section about the use of these completions in conventional plays. This synopsis focuses on HMSF use in unconventionals.

Well Architecture as a Function of Location and Reservoir Properties

As hydraulic fracturing and horizontal wells became popular, many preconceptions associated with hydraulic fracturing had to be reimagined.
