Operators manage and control the bottomhole pressure at a level of stability that enables them to drill in hard-to-drill and impossible-to-drill fields.
APD services allow operators to drill statically underbalanced with significantly reduced mud weights. That allows them to drill with a much lower equivalent circulating density and stay well below fracture gradients reduced by pressure depletion.
Lower ECDs enable operators to tackle margins too costly and technically undrillable with conventional techniques.
These new levels of bottomhole pressure control expands the drilling envelop and extends the productive life of mature fields.
