he first stages are at normal pressure, and are drilled with water-based mud and with control densities ranging between 1.20 a 1.45 gr/cm³; in the case of abnormal densities, this is due to the shale stability control and not because it is required by the pressure gradient. The exploitation stage is drilled with water-based fluid (sodium brine), capable of increasing its viscosity in case of any contingency; it is also friendly to the production formation, and the control density can be adjusted. The Christmas tree dimensions are 9 5/8” x 6 5/8” x 2 7/8” 5,000 lb/pg²; no problems were encountered during the drilling process. 22
