Directional Drilling and Well Flow Engineering (PET505)

Content

The content of the directional drilling part of the course is as follows:

Introduction to different phases of a wells life, construction of well, drilling equipment, drilling process, drilling problems, completion, and associated equipment in 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 the orientation of mudmotor, calculations related to simple two-dimensional well profiles, methods for calculation of position including application in Excel.

The content of the flow engineering part of the course 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 illustrate the use of theory in a numerical simulator for multiphase wellflow. A guided Lab work is anticipated. Measurement techniques and instrumentation by using different sensors, data acquisition, and analysis will be highlighted. In addition, LabDemo illustrating flow regimes will be conducted at the Multiphase Flow lab.
