... have shown good correlation with dynamic properties, such as fluid losses while drilling and high productivity intervals measured in production logs. It was possible to identify two distinct correlations between the increase of pore diameter and permeability response of fractured and vuggy-cavy...

... was expected between the reservoir and fracture pressures, based on correlative well data. Given this condition, conventional drilling methods could cause severe kicks and drilling fluid losses. A managed pressure drilling technique (MPD) makes it possible to exert and maintain a constant bottomhole pressure...
