Abstract

Shale well production performance is influenced by an array of factors including reservoir quality, wellbore trajectory, well completion, and operating conditions and fluid behavior.  Simulation in combination with field measurements offers insights into understanding the interplay between these factors and helps to understand how they impact well performance and, more importantly, how they can enhance well design.   This paper focuses on an analysis of the relationship between well trajectory and production performance for three horizontal shale gas wells in the Horn River.  It presents liquid holdup data obtained through downhole camera and production logging and compares these with results from integrated modeling and transient simulation technologies.  It is important to minimize liquid holdup in the case of shale gas wells as holdup contributes to instabilities and can also plug off contributing stages if those stages are flooded with liquids.  Recommendations on horizontal shale well design are presented.
