Casing on racks- HR Picture by HR

Advanced Casing Design

Instructor: H. Rabia

One week course

Highlights: This course has been attended by practically every major oil company in the world.

The repeat running of this course and the many excellent reviews indicate that this course is one of

the best technical courses available in the petroleum industry.

Objectives

This course offers a practical approach to casing design methods and buckling analysis.

The course is based on numerous wells drilled successfully in many parts of the world including

the UK , Vietnam , Pakistan , Bulgaria , Tunisia , Egypt , Abu Dhabi , Russia , Indonesia , and Yemen.

The course will cover conventional, horizontal and high pressure/ high temperature wells.

Participants will be able to design casings for any well: onshore, offshore, high pressure and

high temperature wells, horizontal and multilateral wells.

^{Dr. Rabia wrote
his definitive textbook "Fundamentals of Casing Design", over 20 years
ago, where he presented the well design method in a structured
way. He also showed for the first time how kick tolerance and kick
profiles can be used to design wells using a variety of well conditions.
Dr. Rabia has since developed and extended most of the ideas presented
in the book into a concise and coherent methodology for well design
using the latest available technology and many ideas from unpublished work
carried out under his supervision.}

^{In his
courses, Dr. Rabia uses actual well design examples from wells he planned and
drilled over the last 23 years. He is still involved in developing and
updating a number of topics including API casing strengths, kick tolerance and
kick profiles, collapse design, shock loading and triaxial methodology. With
his strong background in Rock Mechanics, he combines this
expertise into good effect in showing where best to choose casing seats whilst
maintaining either minimum kick tolerance or company policy on kick
tolerance.}

^{Indeed, a large number
of consultants and some of our competitors still use the original textbook
which has of course been updated several times over but the updates have not
been published. You can only find out the most updated method of well design
by attending our casing design course. No other competitor can
match our expertise in this area. A quick glance at the contents of our
course and our competitors will clearly show how superior our course is
and the depth at which we go into in order to explain the well design
process.}
