SHORT COURSE: BEST PRACTICE IN PORE PRESSURE AND FRACTURE PRESSURE PREDICTION

DATE: 22 – 23 November 2017
TIME: 0900 – 1700 Hrs

COURSE INSTRUCTOR:
RICHARD SWARBRICK
Managing Director, Swarbrick GeoPressure Consultancy Ltd.

COURSE DESCRIPTION:
Pore and fracture pressure prediction define the expected range of the “drilling window” used in planning for well design. These predictions are often required early in the cycle. This course illustrates the data used to create “fit for purpose” pore fluid pressure and fracture pressure predictions in frontier to field development settings.   Estimating pore pressures involves knowledge of the geology and rock-types and a methodology for determining magnitude of any abnormal pressures.

The course will explain the procedures and, through class exercises, will illustrate the quantification methods. Estimating fracture pressures involves knowledge of the local and regional stress field, and application of simple algorithms, which also require input of the pore pressure prediction. Recent research results on pore pressure – fracture pressure coupling values will be reviewed. The course will reinforce the learning outcomes through a range of exercise.

COURSE LEVEL:
Intermediate

LEARNING OBJECTIVES:
In this course, participants will sharpen their knowledge on:

  • Common types and displays of data used in evaluating pressure and predicting pressure at new well locations.
  • The main mechanisms which create abnormal pore pressure.
  • Main methods and their limitations, to estimate pore pressure from a variety of data types acquired from seismic, logs and drilling.
  • How to apply standard algorithms to fracture pressure prediction, and how these are coupled to pore pressure.
  • How to select appropriate calibration data to test prediction outcomes.
  • Why there is uncertainty in pore pressure and fracture pressure predictions.
  • Elements of well planning used to define the “drilling window” and the framework for discussion of results with drilling engineers.

WHO SHOULD ATTEND THIS COURSE?
The course will appeal to geologists, geophysicists, petrophysicists, engineers and their managers or team leaders who are involved in pressure estimation, well selection and planning.

Familiarity with oilfield practice including the acquisition and uses of seismic and log data, and the relationship between mudweight and pressure will be an advantage.
