Global Pore Pressure Prediction …. Some Best Practices
This presentation will discuss some of the ways to reduce drilling costs and prevent “flat time” by making better applications of available technology. Pore pressure and fracture gradient predictions are the most critical parts of every well plan. Managed pressure drilling methods require an even more precise pore pressure profile than do wildcat wells. Extended reach wells also must accurately know the pore pressures in order to properly calculate borehole stability. There are very few types of wells where having a better pore pressure prediction will not result in planning and drilling a better well.
Without knowing the specific cause(s) of the geo-pressures at a proposed drilling location in advance, it is impossible to correctly calculate their magnitude. Most predictions do not make any provision for this fact. Largely as a result of this, operators are experiencing drilling problems that could have been avoided with better pore pressure predictions. Merely trying to apply the most commonly used method does not assure that an estimate is anywhere close to being right. Come and see what some companies have discovered constitutes the best practices in pore pressure prediction technology.
