Abstract
ABSTRACT A fully horizontal well, drilled at an angle from the fracture plane, will experience a potentially substantial increase in the fracturing pressure. The magnitude of this pressure depends on the angle (as the angle increases so does the pressure) and, very importantly, on the value of the intermediate of the three far-field stresses. Application of these findings to eight horizontal wells in the DAN field and comparison with actual data from several fracture treatments within each well showed an excellent match between predicted and observed fracturing pressures. The results are presented in this paper.
