I am trying to create a 2d plot of a directionally drilled oil well. I have a surface location with coordinates and I need to create the borehole using this data from the measurements while drilling survey:

MWD Survey

as you can see, it gives an azimuth and coordinates in N/S ft and E/W ft.

The finished product would look something like this:

Horizontal well plot

Can you point me in the right direction?

I'm using QGIS.

Try using the Azimuth and Distance Plugin as in this answer. After installation it can be accessed via Plugins > Topography.

You will just need to extract your azimuth and distances (presumably "course length") and save only those two columns as a semicolon-delimited csv (not comma-delimited).

Here is what I tried using the data you provided:

Step 1

Extract azimuth and distances to a semicolon-delimited .csv (opened in a text editor below):

Step 2

Open the plugin. Under Options, configure the Survey Type as Boundary, Angle Type as Azimuth, Distance Unit as Feet, and Angle Unit as Gradian.

Step 3

Under the Drawing tab, import the .csv from earlier. If it works correctly you should see it populate the table. If not try and review your csv. Open it in a text editor if needed to double check the formatting.

Choose the active layer (must be linestring geometry) to draw on, or a memory layer, and select a starting point.

Step 4

Click 'Draw'. You may see a popup box that has nothing in it, just ignore it.

This is the result I got (keep in mind I'm using the wrong CRS and made up a point).
