... instant and does not require human synthesis and calculation of the data which must then be relayed to the rig. Theory and Method The use of drilling data to detect pore pressure is rooted in the fundamental assessment that drilling a well disturbs the stress state of the subsurface. As pore fluid...

The properties were initially upscaled using arithmetic averaging and then modeled in 3 dimensions using sequential gaussian simulation. The 3D porosity and permeability models provided an understanding of the reservoir quality along...

... encountered in the petroleum industry is attributed to cognitive biases in project assessments (estimates or forecasts). It has been shown in the literature that if biases are reduced, portfolio profitability is increased. We will demonstrate that biases can be measured quantitatively, and through using...
