Paper: Use of The dc-Exponent To Minimize Drilling Costs In The Delaware Basin

Proper use of d-exponent data accurately predicts formation pressures while drilling in the Delaware Basin. This paper shows how this information can be used to minimize drilling costs by: 1) Proper maintenance of well control. 2) Selection of casing seats. 3) Prediction of hole stability caused by heaving shales in an underbalanced system.
