06. Clarification: Type-well Curve vs Type Curve So let's get some clarity on terminology now. Type-well curves are often referred to as type curves. They are different. I am personally and to use them interchangeably throughout the course of this. So anytime I say type curves, I mean type-well curves, but type curves more properly refer to idealize production plots based on equations and or numerical simulation to which actual production results are compared. Now type-well curves actually use real production data and represent an average production profile for a collection of wells for a specified duration.
