I know. Chapter 25. The first chapters are numbered 1, 2, 25, 7.
Chronologically, chapter 25 occurs before chapter 1. It’s out of place in the narrative.
Most of it is a lesson on how an oil rig works. Five solid pages are devoted to a description of a 90-second oil strike.
The main character doesn’t appear at all. Two new characters appear, one is an ass and the other ... is an ass, but he contributes to the only pleasant scene in the chapter.
Problematic. It needs some dreamy harp music, or narration. “Y’all remember when we struck oil?”
