Center-to-Center Separation Between Two Wellbores

[Georgy1987]

Hello, @jonnymaserati . First of all, you are best and welleng is awesome!

Since you already have all more complex features implemented, I wonder if there is a quick way in welleng to calculate the center-to-center distance from a given reference well MD to the closest offset well point?

Thanks!
Georgy

Thanks for the question @Georgy1987! You actually prompted me to make some updates and issue a new version #149.

Install the new version - the following code should do it, but you might want to do so in a new env and to use the mesh version you probably need the [all] dependencies:

>>> pip install welleng[all] -U

Then create an welleng.clearance.IscwsaClearance instance - take a look at the test_clearance_iscwsa.py file in the tests folder for inspiration.

Hint: use numpy.zeros to make a dummy cov_nev input for the Survey instances.

Then to get the md on the reference well at the closest point to the offset well:

# Create a IscwsaClearance instance:
c_iscwsa = we.clearance.IscwsaClearance(
    survey_ref, survey_off, minimize_sf=True
)

# To get the md along the `ref` well of the closest point to the `off` well:
md_iscwsa = c_iscwsa.ref.md[np.argmin(c_iscwsa.distance_cc)]

Good luck!
