Modern Well Design

Disciplines: Reservoir

Course Description

Describing operational sequences, Modern Well Design presents a unified approach to well design process and walks through an overview from spudding the well through drilling and completion to startup and production.  Attendees will learn elementary rock mechanics and simple ways to analyze borehole stability.  The information is then applied to fracture gradient curve design, which serves as input to the well design process.  Discussions regarding the potential for optimization will conclude the course.


  • Methods for improving borehole stability
  • High-pressure, high-temperature (HPHT) wells
  • Hydraulic optimization and the interpretation of ballooning in deep wells
  • Deepwater, multilateral and long-reach wells
  • Well integrity issues, with examples from the North Sea

Why Attend

Some of the practical solutions given in the course come from many years’ experience in the North Sea, and are not published elsewhere. Each participant will receive a copy of the book Modern Well Design: Second Edition by Bernt S. Aadnoy.

Who Attends

This course is for drilling and production engineers, drilling supervisors, exploration geologists, and others who work on oil and gas wells.


1.6 CEUs (Continuing Education Units) are awarded for this 2-day course.
