COURSE DESCRIPTIONThis is a comprehensive course using the basic models of geology, rock-mechanics and hydrodynamics to predict and appraise subsurface geopressure and, consequently, evaluate your prospect risk pre-and post-drilling.

Participants will learn how to calculate and run their own pore pressure (PP) prediction and analyses, based on a geo-scientific foundation, rather than software design.The course applies a new method of calculating pore pressure and also discusses some of the pitfalls related to specific widely used applications.

The course proceeds from the known (measured pp) to the unknown (predicted pp). It explains the development of the subsurface geopressure compartments with depth and their impact on hydrocarbon entrapments, drilling prognoses and risk assessment.

With the knowledge gained from this course you will be able to QC the measured and predicted input data. You will also learn how to use the seismic velocities and the petrophysical data from offset wells to build the prediction model for a wildcat proposed location. We will lay down the foundation of establishing the prediction variables and exponents needed for each individual basin. Moreover, the course examines in depth the calibration process of the prediction model during and post drilling. Mud weight, casing programs and anticipated drilling challenges will be discussed.
Supra salt, sub-salt models, fault seals, Strat-geopressure fairways, AVG, and drilling challenges are some of the main topics of this course. Moreover, the distribution of geological basins world wide and their impact on geopressure profiles are discussed in case history forms.


  • Understand the causes, concepts and graphic representations of the subsurface geopressured and hydrodynamic systems.
  • Calculate pressure transgression and regression from measured wire-line and log data.

REGISTRATION should be made at least one month before the start of a course. It is recommended that participants register early due to limited seating. However, we will accept paid registrations up to the last business day before the class, provided there are seats available. Registrants will receive a confirmation email within 48 hours of registration and will receive complete venue information two weeks prior to the first day of class.

As a reminder: your seat in a course is not confirmed until payment is received.
