Abstract: A way to analyze/visualize the options available to safely and effectively drill an oil or gas well through a pore pressure/fracture gradient (drilling) window is presented. This method has not been previously recognized or developed and switches the focus from the traditional view using a pressure gradient (mud weight or density) to a view using pressure relative to the pressure that would be supplied by the mud weight that is in the well at a static condition (the baseline). This analysis/visualization has many advantages. It is easy to integrate Managed Pressure Drilling Operations, Horizontal wells, information from logging while drilling tools and in a real-time environment allows for the impact of operational fluctuations to be readily assessed and modeled. It is also envisaged that this analysis/visualization will enable regulatory authorities to better assess the safety of well operations reinforcing their ability to influence safe and effective drilling.
