SPE Distinguished Lecture:
Remediating Cusiana and Cupiagua Fracturing between a Rock and a Hard Place
In Colombia’s Cusiana and Cupiaga fields, initial well rates were disappointing, mostly because of a combination of difficult perforating conditions and significant drilling induced damage. A team was formed to determine if and how BP could fracture stimulate in the most effective manner possible. This team proposed a number of solutions for both the fields that were subsequently implemented. Issues that were addressed included coping with well deviation/azimuth, rigorous prefrac wellbore preparation, novel fracstring deployment, fracturing and an efficient remedial stacking of fracs.
