... and ranges. If velocity model resolution is sufficient, the resultant pressure gradients extracted along interpreted stratigraphic horizons from one of these three-dimensional (3D) earth models yields valuable insights into lateral pressure transfer efficacy, thus informing the net-to-gross (e.g. reservoir...

The change in pressure gradient and liquid holdup across the intermittent to segregated transition is more pronounced at low v SL . In segregated flow, the pressure gradient ( -dp/dL ) increases with pressure...

... and fracture pressure. The mud pressure has to stay within pore pressure and fracture pressure over the entire open hole section. The term pressure gradient is therefore used. When this is no longer possible to achieve, the hole must be cased and cemented such that drilling can continue with a new mud weight...
