How do i begin sketching the wellbore above using design modeler with 2D analysis. I am currently having problems creating different zones like formation, cement, casing and so on. Do I begin by creating the largest circle (formation) or the smallest (annulus)? What do I do after creating the circles is it extruding and sweeping them? Also, my simulation is for temperature distribution and I intend to have results similar to these:

In 2d I'd suggest using the sketch tools and create each section as a separate face (sketch) using a combination of sketch & Concept tools. 

The method you describe above is how I've modelled full 3d bores. Create the bore centreline as a sketch line. Then start with the largest diameter & sweep along the path (frozen). Then the next one down & split. Continue until you have the full well. 

Check your sizes too, 10m is an awfully big hole!

Hi thanks for the response, do u have a 3D geometry sketch of a horizontal wellbore that I can open in workbench? I have done a 2D simulation but I have been required to do a 3D analysis which Im having trouble with. Thank you.

I don't (well, not that I can share anyway). For 3d create a line (sketch for the centre line) and look into the Sweep/Extrude tools.
