PER-FLEX Water-based Drilling Fluid System Successfully Applied in Challenging Colombian Exploratory Well

Location: Monterrey, Colombia

With an increase in exploratory drilling activity in Colombia, different technologies and environmentally-friendly alternatives have been proposed in the Colombian drilling market. An opportunity to use a water-based mud (WBM), in an area where wells are typically drilled with oil-based muds (OBM), was presented to an operator drilling an exploratory well in the Colombian foothills. The bottomhole temperature registered at 270°F (132°C) and there was an overbalanced pressure of 1,800 psi (12.4 MPa). This was the first well drilled by the operator and also the first well drilled completely with a WBM in the zone.

Baker Hughes customized the PER-FLEX™ high-performance water-based drilling fluid system to meet the fluid objectives for the operator. The well was drilled in six sections: five were planned and one was sidetracked in a 12¼-in. hole.
