The use of extensions to CPH is how one enables analysis on informatively censored data. The notion of competing risk is straightforward...

Because of the temperature gradient between rock (permafrost) and oil, there is a probability of wax deposition in the tubing. The deposition-growth model makes different diffusion assumptions.

... and Sikora 1960 ; Prats 1961 ; Binder and Raymond 1967 ). The existing models assume either elliptical or radial flow around the well, with permeability varying azimuthally. Significant differences in the calculated well productivity indicate that earlier assumptions made regarding the flow geometry can lead...

...Kyle Friehauf; Mukul M. Sharma Summary Traditional fracturing models regard fracturing fluids as a single-component, single-phase fluid. This assumption is clearly incorrect for energized fluids where phase changes and mass transfer between phases play important roles in controlling fluid rheology...

... the liquid and gas phases as they pass through the choke. The theoretical basis of the model is a 1D balance equation of mass, momentum, and energy with the assumptions of constant quality and incompressible liquid phase. The present slip model is capable of predicting the critical-subcritical-flow boundary...
