Evaluators commonly use the modified hyperbolic equation to forecast rate-time profiles for unconventional wells. We will examine this equation to confirm its ability to match the physics of fractured horizontal well production and then demonstrate a new, unpublished, physics-based method for determining the modified hyperbolic coefficients.
The literature includes other decline equations proposed for forecasting the production rates from unconventional wells. Several of these equations have limitations, and the lecture will include a discussion of those limitations.
