... Abstract Enhanced seismic velocity models (e.g. semblance or tomography) are key inputs for greenfield pore pressure prediction (PPP) in clastic basins, enabling velocity extraction along the planned well-path and also from a 3d earth-model surrounding the drill-site to test sensitivities...

... or lost in hole, comprehensive well logs are not always available. In the absence of a measured sonic log, a predicted acoustic log can be used for input into the pore pressure prediction avoiding the risk and cost of downhole wellbore logs, however, accuracy is extremely important. A Gradient Boosting...

... are the fine-tuning tools of calibrating the pre-drilling seismic-pressure model. The calibrated model is the backbone of any predicted pore pressure in future drilling locations in the same basin. The pore pressure prediction applying this method facilitates assigning the casing setting and mud programs...

... the carbonates. The approach requires that the inverted data be separated into the shale and carbonate velocity trends to allow the shales to be used for effective stress prediction while the complete velocity field is used for time-depth conversion. These studies have revealed that pore pressure prediction from...

.... The 3D pressure model derived demonstrates that subsalt pore pressure predictions can be obtained from seismic velocities given sufficient offset well data for calibrating a velocity-effective-stress transform. Introduction Drilling for hydrocarbons in a safe and economic manner requires that wellbore...

.... The abstract must contain conspicuous acknowledgment of where and by whom the paper was presented. Abstract An accurate knowledge of formation pore pressure is required for safe and economic drilling in overpressured areas. The use of seismic data for pore pressure prediction is well known, but the seismic...

... Abstract Porosity based pore pressure prediction is based on mechanical compaction of fine-grained sediments with known compressibility behavior. The pitfalls of the prediction methods relate to several challenges in describing overpressured rocks. Firstly, techniques which compare porosity...

The resulting difference in predictedpore pressure may become significant when a pore pressure prediction isrequired outside the interval over which the relation is calibrated, and thisdifference is examined using a deep water Gulf of Mexico case study. Introduction A knowledge of formation pore pressure...

Work is also developing on projects that will address these problems. Pre-drill Pore Pressure Prediction The technical challenge receiving the highest vote...

... Abstract Pore pressure prediction from seismic interval velocity is not a new topic, Pressures predicted using this technique have been typically used to assist the drilling engineer in the design of casing and drilling mud programs for three decades 1 . Implemented this way the technology...

... ABSTRACT Successful techniques of pore pressure prediction from conventional exploration seismic data have been established for several years. These techniques have been modified and adapted for use on multifold digital high resolution data. The initial results show the adaption to be valid...
