摘要

Drilling wells for oil/gas in ultra-deepwater has beenrnincreasingly challenging. The major problem faced in thesernlocations is the very narrow margin between the pore (orrncollapse) and fracture pressures, which leads to numerousrncasing strings needed and, in many cases, the wells end uprnuneconomical. Wells drilled in these scenarios using thernconventional drilling method are extremely risky, and in orderrnto overcome these difficulties several initiatives arernunder way to develop a dual-gradient method, which arernextremely expensive.rnA new drilling method has been developed to tackle thesernproblems, allowing a much safer operation, reducing the risks,rnand also permitting the wells to be drilled to TD (Total Depth)rnmuch cheaper. Drilling is taken to the limit in a safe manner,rnextending each phase as much as possible, using the entirernavailable mud weight window for that well. This new methodrnuses much simpler equipment than the mud lift ones, with veryrnquick field implementation.rnPrevious works1,2 presented this method in detail; thisrnpaper will focus specifically on the method’s application forrndeepwater3. The method brings clear benefits to environmentsrnwith normal to slightly above normal pore pressure. However,rnin high pore pressure scenarios, it can also bring significantrnimprovement in safety and minimizing downtime compared tornthe traditional way of drilling wells.
