PET505_1

Directional Drilling and Well Flow Engineering

This is the study programme for 2020/2021.


The first main part of the course has focus on drilling and well technology. This part gives an overall introduction to the different phases of the lifecycle of a well with special focus on how a well is constructed. In addition, a more in depth study of how different well profiles are obtained by use of directional drilling is given. Here, one will address both application areas, directional drilling concepts, equipment, use of measurements for positioning and perform calculations.
The other main part of the course deals with multiphase flow of liquids, gas and particles in wells and pipelines. This has applications for both the drilling and production phase of wells.

Learning outcome

Have insight into the different phases of a wells lifecycle including drilling, completion, production, intervention and plug and abandonment.
Have knowledge about directional drilling including application areas, directional drilling concepts, different coordinate systems, directional drilling equipment, necessary measurements for positioning and uncertainty in wellbore positioning.
Be able to perform calculations for directional wells which address simple two dimensional well profiles, use of mud motor for changing position, calculation of vertical section and methods for calculating well position based on survey measurements.
Be able to perform hydraulic calculations both for single phase and multiphase flow systems related to well operations considering hole cleaning, well kicks, gas lift operations and production wells.
Be able to use digital tools like Excel and Matlab for analysis of problems and numerical simulation of processes.

Contents

The content of the directional drilling part of the course is:
Introduction to different phases of a wells life, construction of well, drilling equipment, drilling process, drilling problems, completion and associated equipment in a production well, application of directional drilling, directional drilling concepts, coordinate systems, drillstring equipment, drill bits, mud motor, rotary steerable systems, survey measurements, formation logging, geosteering, uncertainty in well positioning, calculations related to orientation of mudmotor, calculations related to simple two dimensional well profiles, methods for calculation of position including application in Excel, Monte Carlo simulation in Matlab.
The content of the flow engineering part is:
Single and multiphase flow including: rheology and fluid properties, flow patterns, fluid fractions and pressure loss calculations in vertical and horizontal wells. Important application areas are hole cleaning, gas kick, gas-lift and flow in production wells and pipelines. Matlab programs which amongst others illustrate the use of theory in a numerical simulator for multiphase wellflow.
