question: using welleng to get back to drilling window #122

Hi Jonny,

I am thinking how to use welleng to do a calculation to get back to the drilling window.

My question is: With current MWD data, and planned path, I would like to calculate a best path that can get back to the planned path that use least slide , as showing in this pic image

Or use 2 curve segment as shoing in this pic image

Do you have suggestions on how to use welleng to calculate a best path?

That's a nice problem @huangkai31.

How constrained is your new target? Can you hit any position on that plane (no lateral constraint, you just need to be at a certain angle at a certain depth) or do you have a defined target?

There are formulas/methods for landing a trajectory which are nice, but these only give you a single solution. Since you're programming though and it takes no time to generate thousands of trajectories, you could make an array of target positions and vectors and iterate through these using the Connector from the kick-off point Node. Then filter your results, e.g. for lowest dls (use a low dls_design parameter) or lowest modified_tortuosity_index. I think your subsurface team will ideas on optimal location and approach angle (inclination and azimuth).

@huangkai31 did you manage to figure this one out?
