Course Description

About the Course:

This course gives an introduction to the capabilities of the Drillbench

Dynamic Hydraulics and the Drillbench Dynamic Well Control modules and will

make the students capable of executing realistic dynamic simulations for

hydraulics and well control situations.

This course comprises of a mixture of lectures and hands-on exercises to

make the student understand the various challenges with drilling hydraulics

and well control operations. The course will be broken down into two parts.

The first part of the course will deal with dynamic hydraulics simulations.

It will starts with an introduction to well hydraulics, and is then

followed by a number of exercises starting with a simple vertical onshore

well to show candidates how to calculated bottom hole pressures, equivalent

circulating densities, static densities and the influence of temperatures

in a well. Wellbore temperatures and hole cleaning aspects will be

addressed.

The second part of the course will deal with the aspects of dynamic well

control. This part starts with an introduction into well control and is

then followed with a number of exercises using the software to demonstrate

how the model can be used to deal with well control aspects and obtain the

results. The well control part also starts with a simple vertical onshore

well and then progresses into the more complex well types.

At the end of the course, the candidates will be familiar with the data

input and the execution of the dynamic simulations and will have gained

significant insight into the complexity of dynamic hydraulics and well

control simulations.
