Interview with Ronald Sweatman

How the formation fluids entered the Macondo wellbore

In this interview, Ron Sweatman, a Houston-based scientist-engineer with 44 patents in the areas of cementing and fracking, explains how the premature setting of the casing seal assembly set in motion a sequence of events in the fluid mechanics of the drilling fluids that caused the Macondo well to become underbalanced. He calls for enhanced training, software and API guidance regarding the effect of temperature differentials between the drilling fluids and geothermal gradient can have on well integrity. Fig. 1 is a diagram of the Macondo well.
